BASIS OF PREPARATION [Abstract]
Basis of Preparation and Seasonality [Text Block]	Basis of Preparation
	The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The consolidated financial statements include the accounts of Euronet and its wholly owned and majority owned subsidiaries and all significant intercompany balances and transactions have been eliminated. Euronet's investments in companies that it does not control, but has the ability to significantly influence, are accounted for under the equity method. Euronet is not involved with any variable interest entities. Results from operations related to entities acquired during the periods covered by the consolidated financial statements are reflected from the effective date of acquisition. Certain amounts in prior years have been reclassified to conform to the current year's presentation.
	The preparation of the consolidated financial statements in conformity with U.S. GAAP requires that management make a number of estimates and assumptions relating to the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses. Significant items subject to such estimates and assumptions include computing income taxes, contingent purchase price consideration, estimating the useful lives and potential impairment of long-lived assets and goodwill, as well as allocating the purchase price to assets acquired and liabilities assumed in acquisitions and revenue recognition. Actual results could differ from those estimates.
	Seasonality
	Euronet’s EFT Processing Segment experiences its heaviest demand for dynamic currency conversion services during the third quarter of the fiscal year, coinciding with the tourism season. Additionally, the EFT Processing and epay Segments are impacted by seasonality during the fourth quarter and first quarter of each year due to higher transaction levels during the holiday season and lower levels following the holiday season. Seasonality in the money transfer segment varies by region of the world. In most markets, Euronet usually experiences increased demand for money transfer services from the month of May through the fourth quarter of each year, coinciding with the increase in worker migration patterns and various holidays, and its lowest transaction levels during the first quarter of the year.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES	Summary of Significant Accounting Policies and Practices
	Foreign currencies
	Assets and liabilities denominated in currencies other than the functional currency of a subsidiary are remeasured at rates of exchange on the balance sheet date. Resulting gains and losses on foreign currency transactions are included in the Consolidated Statements of Income.
	The financial statements of foreign subsidiaries where the functional currency is not the U.S. dollar are translated to U.S. dollars using (i) exchange rates in effect at period end for assets and liabilities, and (ii) weighted average exchange rates during the period for revenues and expenses. Adjustments resulting from translation of such financial statements are reflected in accumulated other comprehensive income (loss) as a separate component of consolidated equity.
	Cash equivalents
	The Company considers all highly liquid investments, with an original maturity of three months or less, and certificates of deposit, which may be withdrawn at any time at the discretion of the Company without penalty, to be cash equivalents.
	Inventory - PINs and other
	Inventory - PINs and other is valued at the lower of cost or market value and primarily represents prepaid personal identification number (“PIN”) inventory for prepaid mobile airtime related to the epay Segment. PIN inventory is generally managed on a specific identification basis that approximates first in, first out for the respective denomination of prepaid mobile airtime sold. Inventory also includes vouchers, merchandise for physical reward fulfillment and other electronic payment products. Additionally, from time to time, Inventory - PINs and other may include POS terminals, mobile phone handsets and ATMs held by the Company for resale.
	Property and equipment
	Property and equipment are stated at cost, less accumulated depreciation. Property and equipment acquired in acquisitions have been recorded at estimated fair values as of the acquisition date.
	Depreciation is generally calculated using the straight-line method over the estimated useful lives of the respective assets. Depreciation and amortization rates are generally as follows:
	ATMs or ATM upgrades	5 - 7 years
	Computers and software	3 - 5 years
	POS terminals	3 - 5 years
	Vehicles and office equipment	3 - 10 years
	Leasehold improvements	Over the lesser of the lease term or estimated useful life
	Goodwill and other intangible assets
	The Company accounts for goodwill and other intangible assets in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 350, Intangibles - Goodwill and Other. ASC Topic 350 requires that the Company test for impairment on an annual basis and whenever events or circumstances dictate. Goodwill is allocated among and evaluated for impairment at the reporting unit level, which is defined as an operating segment or one level below an operating segment.
	ASC Topic 350 provides an entity the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (more than 50%) that the estimated fair value of a reporting unit is less than its carrying amount. If an entity elects to perform a qualitative assessment and determines that an impairment is more likely than not, the entity is then required to perform the existing two-step quantitative impairment test (described below), otherwise no further analysis is required. An entity also may elect not to perform the qualitative assessment and, instead, proceed directly to the two-step quantitative impairment test. The ultimate outcome of the goodwill impairment review for a reporting unit should be the same whether an entity chooses to perform the qualitative assessment or proceeds directly to the two-step quantitative impairment test. The Company has a policy for its annual review of goodwill to perform the qualitative assessment for all reporting units not subjected directly to the two-step quantitative impairment test.
	Under the qualitative assessment, various events and circumstances (or factors) that would affect the estimated fair value of a reporting unit are identified (similar to impairment indicators). These factors are then classified by the type of impact they would have on the estimated fair value using positive, neutral, and adverse categories based on current business conditions. Furthermore, the Company considers the results of the most recent two-step quantitative impairment test completed for a reporting unit and compares, among other factors, the weighted average cost of capital ("WACC") between the current and prior years for each reporting unit.
	During the 2014 annual goodwill impairment test, the Company performed the two-step quantitative impairment test for all but one of the reporting units, including those which would qualify for the qualitative assessment. The quantitative impairment tests were performed to establish a current quantitative test for all reporting units which will used as bases for future qualitative assessments.
	For the qualitative assessment performed on the one reporting unit, the Company concluded that it was more likely than not that the estimated fair value of reporting unit was more than its carrying value. As such, no further analysis was required.
	Under the two-step quantitative impairment test, the evaluation of impairment involves comparing the current fair value of each reporting unit to its carrying value, including goodwill. The Company uses weighted results from the discounted cash flow model ("DCF model") and guideline public company method ("Market Approach model") to estimate the current fair value of its reporting units when testing for impairment, as management believes forecasted cash flows and EBITDA are the best indicator of such fair value. A number of significant assumptions and estimates are involved in the application of the DCF model to forecast operating cash flows, including sales volumes and gross margins, tax rates, capital spending, discount rates and working capital changes. Most of these assumptions vary significantly among the reporting units. Significant assumptions in the Market Approach model are projected EBITDA, selected market multiple, and the estimated control premium.
	In the event the estimated fair value of a reporting unit is less than the carrying value, additional analysis is required. The additional analysis would compare the carrying amount of the reporting unit's goodwill with the implied fair value of that goodwill. The implied fair value of goodwill is the excess of the fair value of the reporting unit over the fair value amounts assigned to all of the assets and liabilities of that unit as if the reporting unit was acquired in a business combination and the fair value of the reporting unit represented the purchase price. If the carrying value of goodwill exceeds its implied fair value, an impairment loss equal to such excess would be recognized.
	No impairment charges were recorded as a result of the 2014 goodwill impairment test. During the 2013 annual goodwill impairment test, the Company completed the two-step quantitative impairment test for nine reporting units. As a result, the Company recorded a non-cash goodwill impairment charge of $18.4 million with respect to the epay Australia and epay Spain reporting units.
	During the 2012 annual goodwill impairment test, the Company completed the two-step quantitative impairment test for eight reporting units. As a result, the Company recorded a non-cash goodwill impairment charge of $23.5 million with respect to the epay Brazil reporting unit.
	Other Intangibles - In accordance with ASC Topic 350, intangible assets with finite lives are amortized over their estimated useful lives. Unless otherwise noted, amortization is calculated using the straight-line method over the estimated useful lives of the assets as follows:
	Non-compete agreements	2 - 5 years
	Trademarks and trade names	2 - 20 years
	Software	3 - 10 years
	Customer relationships	6 - 12 years
	The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If such events or changes in circumstances are present, a loss is recognized if the carrying value of the asset is in excess of the sum of the undiscounted cash flows expected to result from the use of the asset and its eventual disposition. An impairment loss is measured as the amount by which the carrying amount of the asset exceeds the fair value of the asset. During 2012, the Company recorded a non-cash impairment charge of $5.2 million with respect to the customer relationships of the epay Brazil business. No impairment of long-lived assets was recorded during 2014 or 2013.
	See Note 8, Goodwill and Acquired Intangible Assets, Net, for additional information regarding the impairment of goodwill and other intangible assets.
	Other assets
	Other assets include deferred financing costs, investments in unconsolidated affiliates, capitalized software development costs and capitalized payments for new or renewed contracts, contract renewals and customer conversion costs. Deferred financing costs represent expenses incurred to obtain financing that have been deferred and are being amortized over the life of the loan. Euronet capitalizes initial payments for new or renewed contracts to the extent recoverable through future operations, contractual minimums and/or penalties in the case of early termination. The Company's accounting policy is to limit the amount of capitalized costs for a given contract to the lesser of the estimated ongoing net future cash flows related to the contract or the termination fees the Company would receive in the event of early termination of the contract by the customer.
	The Company accounts for investments in affiliates using the equity method of accounting when it has the ability to exercise significant influence over the affiliate. Equity losses in affiliates are generally recognized until the Company's investment is zero. In July 2013, the Company completed the sale of its investment in epay Malaysia for $7.6 million, which resulted in the recognition of a $2.8 million gain. As of December 31, 2014 and 2013, the Company had no material investments in unconsolidated affiliates.
	Convertible notes
	The Company accounts for its convertible debt instruments that may be settled in cash upon conversion in accordance with ASC Topic 470, Debt, which requires the proceeds from the issuance of such convertible debt instruments to be allocated between debt and equity components so that debt is discounted to reflect the Company's nonconvertible debt borrowing rate. Further, the Company applies ASC 470-20-35-13, which requires the debt discount to be amortized over the period the convertible debt is expected to be outstanding as additional non-cash interest expense.
	Noncontrolling interests
	The Company accounts for noncontrolling interests in its consolidated financial statements according to ASC Topic 810, Consolidations, which requires noncontrolling interests to be reported as a component of equity.
	Business combinations
	The Company accounts for business combinations in accordance with ASC Topic 805, Business Combinations, which requires most identifiable assets, liabilities, noncontrolling interests and goodwill acquired in a business combination to be recorded at “full fair value” at the acquisition date. Additionally, ASC Topic 805 requires transaction-related costs to be expensed in the period incurred.
	Income taxes
	Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
	In accordance with ASC Topic 740, Income Taxes, the Company's policy is to record estimated interest and penalties related to the underpayment of income taxes as income tax expense in the Consolidated Statements of Income. See Note 13, Taxes, for further discussion regarding these provisions.
	Presentation of taxes collected and remitted to governmental authorities
	The Company presents taxes collected and remitted to governmental authorities on a net basis in the accompanying Consolidated Statements of Income.
	Fair value measurements
	The Company applies the provisions of ASC Topic 820, Fair Value Measurements and Disclosures, regarding fair value measurements for assets and liabilities. ASC Topic 820 defines fair value, establishes a framework for measuring fair value and requires certain disclosures about fair value measurements. The provisions apply whenever other accounting pronouncements require or permit fair value measurements. See Note 17, Financial Instruments and Fair Value Measurements, for the required fair value disclosures.
	Accounting for derivative instruments and hedging activities
	The Company accounts for derivative instruments and hedging activities in accordance with ASC Topic 815, Derivatives and Hedging, which requires that all derivative instruments be recognized as either assets or liabilities on the balance sheet at fair value. Primarily in the Money Transfer Segment, the Company enters into foreign currency derivative contracts, mainly forward contracts, to offset foreign currency exposure related to the notional value of money transfer settlement assets and liabilities in currencies other than the U.S. dollar. These contracts are considered derivative instruments under the provisions of ASC Topic 815; however, the Company does not designate such instruments as hedges for accounting purposes. Accordingly, changes in the value of these contracts are recognized immediately as a component of foreign currency exchange gain (loss), net in the Consolidated Statements of Income. The impact of changes in value of these contracts, together with the impact of the change in value of the related foreign currency denominated settlement asset or liability, on the Company's Consolidated Statements of Income and Consolidated Balance Sheets is not significant.
	Cash flows resulting from derivative instruments are included in operating activities in the Company's Consolidated Statements of Cash Flows. The Company enters into derivative instruments with highly credit-worthy financial institutions and does not use derivative instruments for trading or speculative purposes. See Note 11, Derivative Instruments and Hedging Activities, for further discussion of derivative instruments.
	Revenue recognition
	The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed or determinable and collection is reasonably assured. The majority of the Company's revenues are comprised of monthly recurring management fees and transaction-based fees. A description of the major components of revenue by business segment is as follows:
	EFT Processing - Revenues in the EFT Processing Segment are primarily derived from transaction and management fees and foreign currency exchange margin from owned and outsourced ATM, POS and card processing networks and from the sale of EFT software solutions for electronic payment and transaction delivery systems, and fees or margin earned from value added services, including dynamic currency conversion.
	Transaction-based fees include charges for cash withdrawals, debit or credit card transactions, balance inquiries, transactions not completed because the relevant card issuer does not give authorization and prepaid mobile airtime recharges. Outsourcing services are generally billed on the basis of a fixed monthly fee per ATM, plus a transaction-based fee. Transaction-based fees are recognized at the time the transactions are processed and outsourcing management fees are recognized ratably over the contract period.
	Certain of the Company's non-cancelable customer contracts provide for the receipt of up-front fees from the customer and/or decreasing or increasing fee schedules over the agreement term for substantially the same level of services to be provided by the Company. The Company recognizes revenue under these contracts based on proportional performance of services over the term of the contract. This generally results in “straight-line” (i.e., consistent value per period) revenue recognition of the contracts' total cash flows, including any up-front payment received from the customer.
	Revenues from the sale of EFT software solutions represent software license fees, professional installation and customization fees, ongoing software maintenance fees, hardware sales and transaction fees. The Company recognizes professional service fee revenue in accordance with the provisions of ASC Topic 985, Software and ASC Topic 605, Revenue Recognition. ASC Topic 985 generally requires revenue earned on software arrangements involving multiple elements to be allocated to each element based on the relative fair values of those elements.
	Revenues from software licensing agreement contracts are recognized over the professional services portion of the contract term using the percentage-of-completion method, following the guidance in ASC Topic 605, as prescribed by ASC Topic 985. Software maintenance revenue is recognized over the contractual period or as the maintenance-related service is performed. Revenues from the sale of hardware are generally recognized when title passes to the customer.
	epay - Revenue generated in the epay Segment is primarily derived from commissions or processing fees associated with distribution and/or processing of prepaid mobile airtime and other electronic payment products. These fees and commissions are received from mobile phone and other telecommunication operators, top-up distributors, other product vendors or distributors or from retailers. In accordance with ASC Topic 605, commissions received are recognized as revenue during the period in which the Company provides the service. The portion of the commission that is paid to retailers is generally recorded as a direct operating cost. However, in circumstances where the Company is not the primary obligor in the distribution of the electronic payment products, those commissions are recorded as a reduction of revenue. In selling certain products, the Company is the primary obligor in the arrangements; accordingly, the gross sales value of the products are recorded as revenue and the purchase cost as direct operating cost. Transactions are processed through a network of POS terminals and direct connections to the electronic payment systems of retailers. Transaction processing fees are recognized at the time the transactions are processed.
	Money Transfer - In accordance with ASC Topic 605, revenues for money transfer and other services represent a transaction fee in addition to a margin earned from purchasing currency at wholesale exchange rates and selling the currency to customers at retail exchange rates. Revenues and the associated direct operating cost are recognized at the time the transaction is processed. The Company has origination and distribution agents in place, which each earn a fee for the respective service. These fees are reflected as direct operating costs.
	Share-based compensation
	The Company follows the provisions of ASC Topic 718, Compensation - Stock Compensation, for equity classified awards, which requires the determination of the fair value of the share-based compensation at the grant date and subsequent recognition of the related expense over the period in which the share-based compensation is earned (“requisite service period”).
	The amount of future compensation expense related to awards of nonvested shares or nonvested share units (“restricted stock”) is based on the market price for Euronet Common Stock at the grant date. The grant date is the date at which all key terms and conditions of the grant have been determined and the Company becomes contingently obligated to transfer equity to the employee who renders the requisite service, generally the date at which grants are approved by the Company's Board of Directors or Compensation Committee thereof. Share-based compensation expense for awards with only service conditions is generally recognized as expense on a “straight-line” basis over the requisite service period. For awards that vest based on achieving periodic performance conditions, expense is recognized on a “graded attribution method.” The graded attribution method results in expense recognition on a straight-line basis over the requisite service period for each separately vesting portion of an award. The Company has elected to use the “with and without method” when calculating the income tax benefit associated with its share-based payment arrangements. See Note 15, Stock Plans, for further disclosure.
Recently issued and adopted accounting pronouncements
Recently Issued - In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard will become effective for the Company on January 1, 2017 and early adoption is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.
Recently Adopted - In July 2013, the FASB issued Accounting Standards Update No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists ("ASU 2013-11"). The amendments in ASU 2013-11 provide guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The Company adopted ASU 2013-11 as of January 1, 2014, and its adoption did not have a material impact on the Company's results of operations, cash flows or financial position.

Stockholders' Equity Note [Abstract]
Stockholders' Equity	Stockholders' Equity
	Earnings Per Share
	Basic earnings per share has been computed by dividing earnings available to common stockholders by the weighted average number of common shares outstanding during the respective period. Diluted earnings per share has been computed by dividing earnings available to common stockholders by the weighted average shares outstanding during the respective period, after adjusting for the potential dilution of options to purchase the Company's Common Stock, assumed vesting of restricted stock and the assumed conversion of the Company's convertible debt.
	The following table provides the computation of diluted weighted average number of common shares outstanding:
		Year Ended December 31,
		2014	2013	2012
	Computation of diluted weighted average shares outstanding:
	Basic weighted average shares outstanding	51,757,867	49,964,819	50,529,476
	Incremental shares from assumed exercise of stock options and vesting of restricted stock	2,143,173	1,953,484	883,034
	Incremental shares from assumed conversion of convertible debentures	—	64,317	—
	Diluted weighted average shares outstanding	53,901,040	51,982,620	51,412,510
	The table includes all stock options and restricted stock that are dilutive to the Company's weighted average common shares outstanding during the period. The calculation of diluted earnings per share excludes stock options or shares of restricted stock that are anti-dilutive to the Company's weighted average common shares outstanding for the years ended December 31, 2014, 2013 and 2012 of approximately 585,000, 438,000 and 3,679,000, respectively.
	In October 2014, the Company issued convertible notes that, if converted, would have a potentially dilutive effect on its Common Stock. At issuance, the Company stated its intent to settle any conversion of these notes by paying cash for the principal value and issuing Common Stock for any conversion value in excess of the principal value. As of December 31, 2014, and currently, the Company maintains the intent and ability to settle any conversion as stated. Accordingly, the convertible notes would only have a dilutive effect if the market price per share of Common Stock exceeds the conversion price per share of Common Stock. Therefore, according to ASC Topic 260, Earnings per Share, these notes were not dilutive to earnings per share for the year ended December 31, 2014. See Note 10, Debt Obligations, for more information about the convertible notes.
	During 2013 and 2012, the Company had convertible debentures that, if converted, would have had a potentially dilutive effect on its Common Stock. In September 2013, the Company repurchased at par the remaining $3.6 million principal amount of the convertible debentures outstanding. Based on the evaluation of these debentures under ASC Topic 260, if dilutive, the impact of the contingently issuable shares was included in the calculation of diluted earnings per share under the “if-converted” method, regardless of whether the conditions upon which the debentures would be convertible into shares of the Company’s Common Stock had been met. Under the if-converted method, the dilutive effect of the assumed conversion of the debentures was 64,317 shares for the year ended December 31, 2013. The assumed conversion of the debentures was anti-dilutive for the year ended December 31, 2012.
	Share repurchases
	In August 2011, the Board of Directors authorized a stock repurchase program ("2011 program") allowing the Company to repurchase up to $100 million in value or 5.0 million shares of its Common Stock. During 2012, the Company repurchased 2.0 million shares at an average purchase price per share of $21.60 for a total value of $42.9 million. The 2011 program expired in August 2013.
	In September 2013, the Board of Directors authorized a stock repurchase program through September 19, 2015 ("2013 program") allowing the Company to repurchase up to $100 million in value or 5.0 million shares of its Common Stock. No repurchases were made in 2014 or 2013 under the 2013 program. Repurchases under the 2013 program may take place in the open market or in privately negotiated transactions, including derivative transactions, and may be made under a Rule 10b5-1 plan.
	In conjunction with the October 2014 convertible note issuance, the Board of Directors approved a separate one-time stock repurchase which resulted in the purchase of 1.2 million shares at an average price per share of $53.47 for a total value of $64.5 million.
	Preferred Stock
	The Company has the authority to issue up to 10 million shares of preferred stock, of which no shares are currently issued or outstanding.
	Stockholder Rights Agreement
	On March 26, 2013, the Company entered into a new Rights Agreement (the "Rights Agreement") with Computershare Trust Company, N.A., as Rights Agent. The Rights Agreement became effective at the close of business on April 3, 2013, immediately following the expiration of the prior rights agreement, and has a three year term. In connection with its approval of the Rights Agreement, the Board of Directors also declared a dividend of one "Right" for each outstanding share of Euronet's common stock, payable on April 3, 2013 to stockholders of record at the close of business on April 3, 2013. As long as the Rights are attached to the common shares, the Company will issue one Right (subject to adjustment) with each new common share that is issued so that all such shares will have attached Rights. When exercisable, each Right will initially entitle the registered holder to purchase from the Company one one-hundredth of a share of Series A Junior Participating Preferred Stock at a price of $125 per one one-hundredth of a share, subject to adjustment. Upon occurrence of a trigger event under the Rights Agreement, each holder of a Right (excluding certain holders) thereafter would have the right to receive upon exercise a number of common shares having a market value of two times the then current price of the Right.
	The Rights are not exercisable until the earlier of (i) ten business days following a public announcement that (or a majority of the Board of Directors of the Company becoming aware that) a person or group of affiliated or associated persons or any person acting in concert therewith, has acquired, or obtained the right to acquire beneficial ownership of 20% or more of the Company's common shares (as defined in the Rights Agreement), or (ii) ten business days following the commencement or announcement of an intention to make a tender offer or exchange offer, the consummation of which would result in any person becoming an acquiring person (as defined in the Rights Agreement), unless the Board of Directors sets a later date in either event. The Rights Agreement is intended to encourage a potential acquiring person to negotiate directly with the Board of Directors, but may have certain anti-takeover effects. The Rights Agreement could significantly dilute the interests in the Company of an acquiring person. The Rights may therefore have the effect of delaying, deterring or preventing a change in control of the Company. The Rights have a de minimus fair value and expire on April 3, 2016.
	Accumulated other comprehensive loss
	As of December 31, 2014 and 2013, accumulated other comprehensive loss consists entirely of foreign currency translation adjustments. The Company recorded a foreign currency translation loss of $87.7 million for the year ended December 31, 2014. For the years ended December 31, 2013 and 2012, the Company recorded foreign currency translation gains of $0.8 million and $10.9 million, respectively. During 2013, the Company reclassified $0.3 million of foreign currency translation into the Consolidated Statements of Income. There were no reclassifications of foreign currency translation into the Consolidated Statements of Income for the years ending December 31, 2014 and 2012.

Acquisitions [Abstract]
Acquisitions [Text Block]	Acquisitions
	In accordance with ASC Topic 805, the Company allocates the purchase price of its acquisitions to the tangible assets, liabilities and intangible assets acquired based on fair values. Any excess purchase price over those fair values is recorded as goodwill. The fair value assigned to intangible assets acquired is supported by valuations using estimates and assumptions provided by management. Generally, for certain large acquisitions, management engages an appraiser to assist in the valuation process.
	2014 Acquisitions
	On May 20, 2014, the Company completed the acquisition of all of the capital stock of EIM (FX) Limited and TBK (FM) Limited (the "Acquired Companies") pursuant to a Share Purchase Agreement dated March 7, 2014 (the "Purchase Agreement") among the Company and the selling shareholders (the "Sellers"). The Acquired Companies, each a United Kingdom limited company, own subsidiaries that operate under the brand names HiFX and HiFM, respectively.
	HiFX offers account-to-account international payment services to high-income individuals and small-to-medium sized businesses, complementing Euronet’s existing consumer-to-consumer money transfer business. HiFX has an innovative multi-channel platform which allows customers to make transfers, track payments and manage their international payment activity online or through a customer service representative. HiFM offers cash management solutions and foreign currency risk management services to small-to-medium sized businesses.
	Under the terms of the Purchase Agreement, the Sellers received purchase consideration (the "Purchase Consideration") of £111.8 million in cash ($188.0 million), including working capital adjustments finalized in the third quarter of 2014, and 1,262,654 shares of Euronet common stock, with a fair value at date of acquisition of $56.6 million (the "Consideration Shares"). An amount equal to $16.0 million of the cash portion of the Purchase Consideration and all of the Consideration Shares were placed in escrow at closing as security for the Sellers' indemnification and other obligations under the Purchase Agreement. Any Purchase Consideration remaining in escrow will be released to the Sellers two years following the closing date, net of any pending indemnification or other claims under the Purchase Agreement.
	The Purchase Consideration was allocated to the assets acquired and liabilities assumed, including identifiable intangible assets, based on their respective fair values at the date of acquisition. None of the goodwill or intangible asset amounts are expected to be deductible for income tax purposes. Pro-forma results of operations, assuming this acquisition was made at the beginning of the earliest period presented, have not been presented because the effect of this acquisition was not material to the Company's results. The net assets of the Acquired Companies and their results from operations after the acquisition are included in the Money Transfer Segment's results.
	During the third and fourth quarters of 2014, the Company adjusted the purchase price allocation of the Acquired Companies and finalized the allocation as of December 31, 2014. Changes from the Company's preliminary estimates as of June 30, 2014 were not material to its consolidated financial statements. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed as of the acquisition date.
	(in thousands)	As of May 20, 2014

	2013 Acquisitions
	On January 4, 2013, the Company acquired all of the common stock of an Australian company, Pure Commerce Pty Limited (“Pure Commerce”), which offers industry leading currency conversion and multi-currency acquiring products to global, local and online merchant acquirers, banks and retailers. The purchase price consisted of cash of approximately $31.3 million, subject to customary purchase price adjustments, and $5.3 million of the Company's common stock. With respect to the stock portion of the purchase price and pursuant to the acquisition agreement, the Company issued at closing 224,425 shares of common stock to the shareholders of Pure Commerce. Further, Euronet agreed, pursuant to an earnout provision, to pay additional purchase consideration of up to $30.0 million Australian dollars if certain performance targets were met during the measurement period ending December 31, 2013. As of the acquisition date, the fair value of the contingent consideration liability was $21.7 million. Pure Commerce did not meet the minimum performance targets necessary to require the Company to pay contingent consideration. See Note 17, Financial Instruments and Fair Value Measurements, for additional information related to the contingent consideration liability.

	2012 Acquisitions
	In January 2012, the Company acquired the remaining 51% of the common stock of Euronet Middle East W.L.L. which it did not previously own. The purchase price of approximately $6.4 million was paid from cash on hand. Accordingly, the assets and liabilities of Euronet Middle East W.L.L. were recorded at fair value, which resulted in a $4.4 million pre-tax gain on the 49% interest previously owned.
	In November 2012, the Company acquired certain assets and retail contracts of ezi-pay Limited ("ezi-pay"), which added additional product offerings, and processing and distribution services for New Zealand-specific brands to the Company's epay operations in Europe. The purchase price of approximately $19.7 million was paid from cash on hand. Additionally, $3.3 million in cash is being held in escrow to secure certain obligations of the sellers under the acquisition agreement.
	The following table summarizes the fair values of the acquired net assets at the respective acquisition dates:

	The Company performs its annual goodwill impairment test during the fourth quarter of each year. The annual goodwill impairment test completed during the fourth quarter of 2014 resulted in no impairment charge. As a result of the 2013 and 2012 annual goodwill impairment tests, the Company recorded non-cash goodwill impairment charges of $18.4 million and $23.5 million, respectively.
	In performing the annual goodwill impairment test, management must apply judgment in determining the estimated fair value of a business and uses all available information to make these fair value determinations, including discounted projected future cash flow analysis using discount rates commensurate with the risks involved in the assets, together with comparable sales prices that the Company or another purchaser would likely pay for the respective assets.
	Of the total goodwill balance of $599.9 million as of December 31, 2014, $370.7 million relates to the Money Transfer Segment, $171.0 million relates to the epay Segment and the remaining $58.2 million relates to the EFT Processing Segment. Amortization expense for intangible assets with finite lives was $24.4 million, $21.1 million and $22.1 million for the years ended December 31, 2014, 2013 and 2012, respectively. Estimated annual amortization expense, before income taxes, on intangible assets with finite lives as of December 31, 2014, is expected to total $22.0 million for 2015, $20.4 million for 2016, $18.3 million for 2017, $16.0 million for 2018 and $15.2 million for 2019.
	2013 Impairment Charges
	As a result of the 2013 annual goodwill impairment test, the Company recorded non-cash goodwill impairment charges related to its epay reporting units in Australia and Spain of $12.3 million and $6.1 million, respectively. The goodwill impairment charge in Australia was the result of continuing declines in the demand for mobile top-up services, caused by certain large retailers (which have a significant share of the retail market) negotiating direct agreements with two mobile operators and certain mobile operators modifying their distribution strategies to drive consumer demand for top-up services to on-line or mobile device channels. In Spain, the goodwill impairment charge was the result of the longer term effect of poor economic conditions, including continued high levels of unemployment and increased competitive pressures. In response to the business challenges in Australia and Spain, the Company has continued to sell additional products and services to mobile operators and develop strategies to increase the distribution of other prepaid products. However, in the fourth quarter of 2013, the Company concluded that while future cash flows from existing agreements with mobile operators and from the launch of new products would likely grow steadily over time, the growth would not add the level of cash flows previously forecasted. Based upon these revised future cash flow forecasts, the Company concluded that the resulting valuations were not sufficient to support the goodwill carrying values of epay Australia and epay Spain. Therefore, the impairment charges were recorded in the period. There are no remaining goodwill or acquired intangible assets in the epay Australia and Spain reporting units as of December 31, 2013.
	2012 Impairment Charges
	In the fourth quarter of 2012, epay Brazil recorded a goodwill impairment charge of $23.5 million and an additional $5.2 million impairment charge of other acquired intangibles assets, specifically customer relationships. The impairment charges were the cumulative result of a culmination of several factors in Brazil including, but not necessarily limited to, changes in mobile operator distribution strategies, delays in non-mobile product distribution and operating costs.
	The initial factor contributing to the impairment charges was changes in certain mobile operators' distribution strategies throughout 2012. These changes limited the Company's ability to distribute certain mobile operators' products in certain markets and had a negative impact on epay Brazil's 2012 results. While the changes affected the 2012 results, the Company continued to negotiate alternative arrangements with the mobile operators in order to regain profitability in Brazil. In the fourth quarter of 2012, the Company determined that these negotiations were not likely to result in arrangements that would restore its profitability from those products in the future.
	While these distribution changes were occurring, the Company was also establishing plans to introduce other electronic payment products in the Brazilian market which was expected to increase profitability. As the plans became more concrete in the fourth quarter of 2012, the Company's assessment was that the added profitability from these new products would likely grow steadily over time, but would not add significant earnings as quickly as originally projected.
	Simultaneously with the changes in the mobile operators' distribution strategies, epay Brazil undertook efforts to align costs with revenues. While significant progress was made in reducing costs during 2012, the extent of that progress was constrained by the investments needed to launch the new electronic payment products. In the fourth quarter of 2012, the revised cost structure, which aligns costs with the decreased mobile revenues and supports the new products, was solidified and resulted in cost savings which were less than initially expected.
	Further, the changes in the mobile operators' distribution strategies accelerated efforts to pursue other distribution channels. In the fourth quarter of 2012, epay Brazil acquired new partners in these other channels which provided insight to the profit potential of these channels. The Company's assessment of the opportunity in these channels was that while these channels are expected to be profitable, they are not likely to have profit margins as great as the ones lost with the changes in mobile operators' distribution strategies previously discussed.
	As described above, the Company had several initiatives to improve profitability which were evolving during the year. The collective impact of those initiatives was the key consideration to determining if the epay Brazil business could return to or exceed its previous profitability. While each initiative had the potential to significantly contribute to that goal, during the fourth quarter of 2012, the Company determined that each initiative was likely to contribute less than what was previously expected. The culmination of these various factors in the fourth quarter of 2012 led the Company to conclude that the resulting valuation was not sufficient to support the recorded value of its investment in epay Brazil and, therefore, it recorded the goodwill and other acquired intangible assets impairment charges in the period.

	Long-term debt obligations	$	410,368		$	188,510
	As of December 31, 2014, aggregate annual maturities of long-term debt are $5.2 million in 2015, $7.0 million in 2016, $8.9 million in 2017, $13.6 million in 2018, $42.8 million in 2019 and none thereafter. This maturity schedule reflects the term loan and revolving credit facilities maturing in 2019.
	Credit Facility
	On August 18, 2011, the Company and certain of its subsidiaries entered into an Amended and Restated Credit Agreement (the "Credit Agreement") with a lending syndicate consisting of nine banks (the "Lenders") with Bank of America, N.A. serving as Administrative Agent and Collateral Agent and U.S. Bank National Association serving as Syndication Agent.
	On April 9, 2014, the Company amended and restated the Credit Agreement to, among other things, (i) increase the amount of Term Loan A from $66 million to $75 million, (ii) increase the aggregate credit commitments under the revolving credit facility from $400 million to $600 million, (iii) reduce the margin over the London Inter-Bank Offered Rate (“LIBOR”) rate and base rate by 12.5 basis points, and (iv) extend the expiration date of the Credit Agreement from August 18, 2016 to April 9, 2019. In connection with the amendment, the Company incurred $2.5 million in debt issuance costs, which are being amortized over the term of the Credit Facility.
	Under the Credit Agreement, the Lenders have made available a $675 million senior secured credit facility (the "Credit Facility") consisting of a $590 million five-year revolving credit facility, a $10 million five-year India revolving credit facility and a $75 million five-year term loan which has been reduced to $72.2 million as of December 31, 2014 through principal amortization payments. The revolving credit facility allows for borrowings in U.S. dollars, euro, British pound sterling, Australian dollars and/or Indian rupees. The revolving credit facility contains a $200 million sublimit for the issuance of letters of credit and a $25 million sublimit for swingline loans.
	Fees and interest on borrowings vary based upon the Company's consolidated total leverage ratio (as defined in the Credit Agreement) and will be based, in the case of letter of credit fees, on a margin, and in the case of interest, on a margin over London Inter-Bank Offered Rate (“LIBOR”) or a margin over the base rate, as selected by the Company, with the applicable margin ranging from 1.375% to 2.375% (or 0.375% to 1.375% for base rate loans). The base rate is the highest of (i) the Bank of America prime rate, (ii) the Federal Funds rate plus 0.50% or (iii) the Fixed LIBOR rate plus 1.00%. The term loan is subject to scheduled quarterly amortization payments, as set forth in the Credit Agreement. The maturity date for the Credit Facility is April 9, 2019, at which time the outstanding principal balance and all accrued interest will be due and payable in full. The weighted average interest rate of the Company's borrowings under the term loan and revolving credit facility was 1.5% and 11.3%, respectively, as of December 31, 2014, and 1.7% for each as of December 31, 2013.
	As of December 31, 2014 and 2013, the Company had stand-by letters of credit/bank guarantees outstanding against the revolving credit facility of $63.6 million and $58.7 million, respectively. Stand-by letters of credit/bank guarantees reduce the Company's borrowing capacity under the revolving credit facility and are generally used to secure trade credit and performance obligations. The Company pays an interest rate for stand-by letters of credit/bank guarantees at a rate that may adjust each quarter based upon the Company's consolidated total leverage ratio. As of December 31, 2014 and 2013, the stand-by letters of credit interest charges were 1.38% and 1.50% per annum, respectively.
	The Credit Agreement contains customary affirmative and negative covenants, events of default and financial covenants, including (all as defined in the Credit Agreement): (i) a Consolidated Total Leverage Ratio not to exceed 4.0 to 1.0; and (ii) a Consolidated Fixed Charge Coverage Ratio of not less than 1.5 to 1.0. Subject to meeting certain leverage ratio and liquidity requirements (as defined in the Credit Agreement), the Company is permitted to pay dividends, repurchase common stock and repurchase subordinated debt.
	The Company and certain subsidiaries have guaranteed the repayment of obligations under the Credit Facility and have granted pledges of the shares of certain subsidiaries along with a security interest in certain other personal property collateral of the Company and certain subsidiaries.
	Convertible Debt
	On October 30, 2014, the Company completed the sale of $402.5 million of Convertible Senior Notes due 2044 (“Convertible Notes”). The Convertible Notes have an interest rate of 1.5% per annum payable semi-annually in April and October, and are convertible into shares of Euronet Common Stock at a conversion price of approximately $72.18 per share if certain conditions are met (relating to the closing prices of Euronet Common Stock exceeding certain thresholds for specified periods). Holders of the Convertible Notes have the option to require the Company to purchase their notes at par on October 1, 2020, and have additional options to require the Company to purchase their notes at par on October 1, 2024, 2029, 2034, and 2039, or upon a change in control of the Company. In connection with the issuance of the Convertible Notes, the Company recorded $10.7 million in debt issuance costs, which are being amortized through October 1, 2020.
	In accordance with ASC 470-20-30-27, proceeds from the issuance of convertible debt is allocated between debt and equity components so that debt is discounted to reflect the Company's nonconvertible debt borrowing rate. ASC 470-20-35-13 requires the debt discount to be amortized over the period the convertible debt is expected to be outstanding as additional non-cash interest expense. The allocation resulted in an increase to additional paid in capital of $66.1 million.
	Contractual interest expense was $0.9 million and accretion expense was $1.6 million for the year ended December 31, 2014. The effective interest rate was 4.7% for the year ended December 31, 2014. As of December 31, 2014, unamortized discounts were $64.5 million, and will be amortized through October 1, 2020.
	On October 4, 2005, the Company completed the sale of $175.0 million of Contingent Convertible Debentures Due 2025 (“2025 Convertible Debentures”). The 2025 Convertible Debentures had an interest rate of 3.5% per annum and were convertible into shares of Euronet Common Stock under certain circumstances. Holders of the 2025 Convertible Debentures had the option to require the Company to purchase their debentures at par on October 15, 2012 and most of them exercised their option which resulted in the Company purchasing $167.9 million of the 2025 Convertible Debentures. In September 2013, the Company repurchased at par the remaining principal amount of 2025 Convertible Debentures outstanding.
	Contractual interest expense for the 2025 Convertible Debentures was $0.1 million and $4.8 million for the years ended December 31, 2013 and 2012, respectively. The effective interest rate was 8.4% for all periods through October 15, 2012 and 3.5% thereafter. Discount accretion expense was $6.3 million for the year ended December 31, 2012.
	Other obligations
	Certain of the Company's subsidiaries have available lines of credit and an overdraft credit facility that provide for short-term borrowings that are used from time to time for working capital purposes. As of December 31, 2014 and 2013, borrowings under these arrangements were $6.0 million and $2.4 million, respectively.

Derivative Instruments and Hedging Activities (Note)	12 Months Ended
	Dec. 31, 2014
Derivative Instruments and Hedges, Assets [Abstract]
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	Derivative Instruments and Hedging Activities
	The Company is exposed to foreign currency exchange risk resulting from (i) the collection of funds or the settlement of money transfer transactions in currencies other than the U.S. dollar, (ii) derivative contracts written to its customers in connection with providing cross-currency money transfer services and (iii) short-term borrowings that are payable in currencies other than the U.S dollar. The Company enters into foreign currency derivative contracts, primarily foreign currency forwards and cross-currency swaps, to minimize its exposure related to fluctuations in foreign currency exchange rates. As a matter of Company policy, the derivative instruments used in these activities are economic hedges and are not designated as hedges under ASC Topic 815, Derivatives and Hedging, primarily due to either the relatively short duration of the contract term or the effects of fluctuations in currency exchange rates are reflected concurrently in earnings for both the derivative instrument and the transaction and have an offsetting effect.
	Foreign currency exchange contracts - Ria Operations
	In the United States, the Company uses short-duration foreign currency forward contracts, generally with maturities up to 14 days, to offset the fluctuation in foreign currency exchange rates on the collection of money transfer funds between initiation of a transaction and its settlement. Due to the short duration of these contracts and the Company’s credit profile, the Company is generally not required to post collateral with respect to these foreign currency forward contracts. Most derivative contracts executed with counterparties in the U.S. are governed by an International Swaps and Derivatives Association agreement that includes standard netting arrangements; therefore, asset and liability positions from forward contracts and all other foreign exchange transactions with the same counterparty are net settled upon maturity.
	As of December 31, 2014, the Company had foreign currency forward contracts outstanding in the U.S. with a notional value of $116 million, primarily in Australian dollars, Canadian dollars, British pounds, euros and Mexican pesos.
	Foreign currency exchange contracts - HiFX Operations
	As discussed in Note 5, Acquisitions, on May 20, 2014, the Company acquired EIM (FX) Limited, which owns subsidiaries that operate under the brand name HiFX. HiFX writes derivative instruments, primarily foreign currency forward contracts and cross-currency swaps, mostly with counterparties comprised of individuals and small-to-medium size businesses and derives a currency margin from this activity as part of its operations. HiFX aggregates its foreign currency exposures arising from customer contracts and hedges the resulting net currency risks by entering into offsetting contracts with established financial institution counterparties. Foreign exchange revenues from HiFX's total portfolio of positions were $37.3 million for the year ended December 31, 2014. All of the derivative contracts used in the Company' s HiFX operations are economic hedges and are not designated as hedges under ASC Topic 815, Derivatives and Hedging. The duration of these derivative contracts is generally less than one year.
	The fair value of HiFX's total portfolio of positions can change significantly from period to period based on, among other factors, market movements and changes in customer contract positions. HiFX manages counterparty credit risk (the risk that counterparties will default and not make payments according to the terms of the agreements) on an individual counterparty basis. It mitigates this risk by entering into contracts with collateral posting requirements and/or by performing financial assessments prior to contract execution, conducting periodic evaluations of counterparty performance and maintaining a diverse portfolio of qualified counterparties. HiFX does not expect any significant losses from counterparty defaults.
	The aggregate equivalent U.S. dollar notional amounts of foreign currency derivative customer contracts held by the Company in its HiFX operations as of December 31, 2014 was approximately $729 million. The significant majority of customer contracts are written in major currencies such as the euro, Canadian dollar, British pound, and Australian dollar.

Subsequently recognized tax benefits relating to the valuation allowance for deferred tax assets as of December 31, 2014 are expected to be allocated to income taxes in the Consolidated Statements of Income with the following exception. The tax benefit of net operating losses generated from share-based compensation have been excluded from the amounts disclosed for tax loss carryforwards and valuation allowance to the extent the benefit will be recognized in equity if realized. The excluded tax benefit of $25.6 million will be allocated to additional paid-in capital when utilized to offset taxable income.
As of December 31, 2014, and 2013, the Company's U.S. federal and foreign tax loss carryforwards were $180.1 million and $155.8 million, respectively, and U.S. state tax loss carryforwards were $62.7 million and $56.4 million, respectively.
In assessing the Company's ability to realize deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, management believes it is more likely than not the Company will only realize the benefits of these deductible differences, net of the existing valuation allowances, as of December 31, 2014.
As of December 31, 2014, the Company had U.S. federal and foreign tax net operating loss carryforwards of $180.1 million, which will expire as follows:
(in thousands)		Gross			Tax Effected
Year ending December 31,
2015		$	2,101		$	515
2016		4,292			1,052
2017		2,146			495
2018		1,769			375
2019		2,111			513
Thereafter		137,859			43,422
Unlimited		29,822			7,369
Total		$	180,100		$	53,741
In addition, the Company's state tax net operating loss carryforwards of $62.7 million will expire periodically from 2015 through 2034.
No provision has been made in the accounts as of December 31, 2014 for U.S. federal and state income taxes which would be payable if the gross undistributed earnings of the foreign subsidiaries were distributed to the Company since management has determined that the earnings are permanently reinvested. Gross undistributed earnings reinvested indefinitely in foreign subsidiaries aggregated $684.9 million as of December 31, 2014. The determination of the amount of unrecognized deferred U.S. income tax liabilities and foreign tax credits, if any, is not practicable to calculate at this time.
Accounting for uncertainty in income taxes
A reconciliation of the beginning and ending amount of unrecognized tax benefits for the years ended December 31, 2014 and 2013 is as follows:
		Year Ended December 31,
(in thousands)		2014			2013
Beginning balance		$	14,242		$	11,370
Additions based on tax positions related to the current year		2,427			5,570
Reductions for tax positions of prior years		(1,641		)	(427		)
Settlements		—			(2,271		)
Ending balance		$	15,028		$	14,242
As of December 31, 2014 and 2013, approximately $10.1 million and $9.2 million, respectively, of the unrecognized tax benefits would impact the Company's provision for income taxes and effective income tax rate, if recognized. Unrecognized tax benefits of approximately $1.8 million are presented in the December 31, 2014 financial statements as a reduction to the Company's deferred tax asset for tax loss carryforwards. Total estimated accrued interest and penalties related to the underpayment of income taxes was $2.8 million and $2.2 million as of December 31, 2014 and 2013, respectively. The following income tax years remain open in the Company's major jurisdictions as of December 31, 2014:
Jurisdictions	Periods
U.S. (Federal)	2000 through 2002, 2004 through 2006, and 2010 through 2014
Spain	2009 through 2014
Australia	2010 through 2014
U.K.	2009 through 2014
Germany	2009 through 2014
The application of ASC 740-10-25 and -30 requires significant judgment in assessing the outcome of future income tax examinations and their potential impact on the Company's estimated effective income tax rate and the value of deferred tax assets, such as those related to the Company's net operating loss carryforwards. It is reasonably possible that the balance of gross unrecognized tax benefits could significantly change within the next twelve months as a result of the resolution of audit examinations and expirations of certain statutes of limitations and, accordingly, materially affect the Company's operating results. At this time, it is not possible to estimate the range of change due to the uncertainty of potential outcomes.

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	Stock Plans
	The Company has share-based compensation plans (“SCP”) that allow it to grant restricted shares, or options to purchase shares, of Common Stock to certain current and prospective key employees, directors and consultants of the Company. These awards generally vest over periods ranging from three to seven years from the date of grant, are generally exercisable during the shorter of a ten-year term or the term of employment with the Company. Certain stock option grants vest over a five-year period, subject to the achievement of pre-determined performance targets. With the exception of certain awards made to the Company's employees in Germany, awards under the SCP are settled through the issuance of new shares under the provisions of the SCP. For Company employees in Germany, certain awards are settled through the issuance of treasury shares, which also reduces the number of shares available for future issuance under the SCP. As of December 31, 2014, the Company has approximately 4.8 million in total shares remaining available for issuance under the SCP.
	Share-based compensation expense was $12.9 million, $11.5 million and $11.8 million for the years ended December 31, 2014, 2013 and 2012, respectively, and is recorded in salaries and benefits expense in the accompanying Consolidated Statements of Income. The Company recorded a tax benefit of $0.8 million, $0.6 million and $0.7 million during the years ended December 31, 2014, 2013 and 2012, respectively, for the portion of this expense that relates to foreign tax jurisdictions in which an income tax benefit is expected to be derived.

	Employee stock purchase plan
	The Company has a qualified Employee Stock Purchase Plan (the “ESPP”), which allows qualified employees (as defined by the plan documents) to participate in the purchase of rights to purchase designated shares of the Company's Common Stock at a price equal to the lower of 85% of the closing price at the beginning or end of each quarterly offering period. The Company reserved 1,000,000 shares of Common Stock for purchase under the ESPP. Pursuant to the ESPP, during the years ended December 31, 2014, 2013 and 2012, the Company issued 50,470, 44,323 and 56,189 rights, respectively, to purchase shares of Common Stock at a weighted average price per share of $38.04, $25.06 and $15.42, respectively. The grant date fair value of the option to purchase shares at the lower of the closing price at the beginning or end of the quarterly period, plus the actual total discount provided, are recorded as compensation expense. Total compensation expense recorded was $0.5 million for the years ended December 31, 2014 and $0.2 million for each of the years ended December 31, 2013 and 2012. The following table provides the weighted-average fair value of the ESPP stock purchase rights during the years ended December 31, 2014, 2013 and 2012 and the assumptions used to calculate the fair value using the Black-Scholes-Merton option-pricing model:

FAIR VALUE MEASUREMENTS

Financial Instruments and Fair Value Measurements

Concentrations of credit risk

The Company's credit risk primarily relates to trade accounts receivable and cash and cash equivalents. The EFT Processing Segment's customer base includes the most significant international card organizations and certain banks in its markets. The epay Segment's customer base is diverse and includes several major retailers and/or distributors in markets that they operate. The Money Transfer Segment trade accounts receivable are primarily due from independent agents that collect cash from customers on the Company's behalf and generally remit the cash within one week. The Company's performs ongoing evaluations of its customers' financial condition and limits the amount of credit extended, or purchases credit enhancement protection, when deemed necessary, but generally requires no collateral. See Note 14, Valuation and Qualifying Accounts, for further disclosure.

The Company invests excess cash not required for use in operations primarily in high credit quality, short-term duration securities that the Company believes bear minimal risk.

Fair value measurements

Fair value measurements used in the consolidated financial statements are based upon the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below:

•

Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities.

•

Level 2 – Valuations based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities.

•

Level 3 – Unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its own assumptions about the inputs that market participants would use in pricing.

The following table details financial assets measured and recorded at fair value on a recurring basis:

The carrying amounts of cash and cash equivalents, trade accounts receivable, trade accounts payable and short-term debt obligations approximate fair values due to their short maturities. The carrying values of the Company’s term loan due 2019 and revolving credit agreements approximate fair values because interest is based on the London Inter-Bank Offered Rate ("LIBOR") that resets at various intervals of less than one year. The Company estimates the fair value of the convertible notes using quoted prices in inactive markets for identical liabilities (Level 2). As of December 31, 2014, the fair value of the convertible notes was $408.0 million with a carrying value of $338.0 million.

Contingent Consideration Liability

The contingent consideration liability relating to the Pure Commerce acquisition was recorded at fair value using a Monte Carlo simulation. The significant unobservable inputs used in the fair value measurement of the contingent consideration liability are forecasted financial results, including estimates of future revenues, gross profit, and EBITDA (Level 3). As of the acquisition date, the fair value of the contingent consideration liability was $21.7 million. Changes in any of these inputs could result in a significantly higher or lower fair value measurement. Changes in the fair value of the contingent consideration liability are recorded as income or expense within operating income in the Company's Consolidated Statements of Income.

During 2013, the Company recorded a $2.4 million foreign currency exchange gain related to this contingent consideration liability as a result of fluctuations in the value of the Australian dollar against the U.S. dollar. In third quarter of 2013, the Company adjusted to fair value the contingent consideration liability based on its assessment that the performance targets for gross profit and EBITDA would not be met. As of December 31, 2013 (end of the performance period), the fair value of the contingent consideration liability is zero. The change in fair value resulted in the recognition of a $19.3 million gain.

Impairment of goodwill and acquired intangible assets

Certain assets are measured at fair value on a non-recurring basis. In connection with the annual goodwill impairment test during the fourth quarters of 2013 and 2012, the Company assessed the fair value of goodwill and recorded goodwill impairment charges related to certain of its epay reporting units of $18.4 million and $23.5 million, respectively. The fair values were determined using significant unobservable inputs (Level 3). The fair values of goodwill related to impaired reporting units were determined by calculating the implied fair values as the excess of the fair value of the respective entity over the fair value of its net assets. Further, in 2012, the Company recorded an impairment charge of acquired intangible assets of $5.2 million, specifically related to customer relationship assets in Brazil. The acquired intangible asset impairment charge was measured as the amount by which the carrying amount of the asset exceeded the fair value of the asset. No other assets were measured at fair value on a non-recurring basis during 2014, 2013, or 2012.

Accounting Policies [Abstract]
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign currencies
	Assets and liabilities denominated in currencies other than the functional currency of a subsidiary are remeasured at rates of exchange on the balance sheet date. Resulting gains and losses on foreign currency transactions are included in the Consolidated Statements of Income.
	The financial statements of foreign subsidiaries where the functional currency is not the U.S. dollar are translated to U.S. dollars using (i) exchange rates in effect at period end for assets and liabilities, and (ii) weighted average exchange rates during the period for revenues and expenses. Adjustments resulting from translation of such financial statements are reflected in accumulated other comprehensive income (loss) as a separate component of consolidated equity.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash equivalents
	The Company considers all highly liquid investments, with an original maturity of three months or less, and certificates of deposit, which may be withdrawn at any time at the discretion of the Company without penalty, to be cash equivalents.
Inventory, Policy [Policy Text Block]	Inventory - PINs and other
	Inventory - PINs and other is valued at the lower of cost or market value and primarily represents prepaid personal identification number (“PIN”) inventory for prepaid mobile airtime related to the epay Segment. PIN inventory is generally managed on a specific identification basis that approximates first in, first out for the respective denomination of prepaid mobile airtime sold. Inventory also includes vouchers, merchandise for physical reward fulfillment and other electronic payment products. Additionally, from time to time, Inventory - PINs and other may include POS terminals, mobile phone handsets and ATMs held by the Company for resale.
Property, Plant and Equipment, Policy [Policy Text Block]	Property and equipment
	Property and equipment are stated at cost, less accumulated depreciation. Property and equipment acquired in acquisitions have been recorded at estimated fair values as of the acquisition date.
	Depreciation is generally calculated using the straight-line method over the estimated useful lives of the respective assets. Depreciation and amortization rates are generally as follows:
	ATMs or ATM upgrades	5 - 7 years
	Computers and software	3 - 5 years
	POS terminals	3 - 5 years
	Vehicles and office equipment	3 - 10 years
	Leasehold improvements	Over the lesser of the lease term or estimated useful life
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and other intangible assets
	The Company accounts for goodwill and other intangible assets in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 350, Intangibles - Goodwill and Other. ASC Topic 350 requires that the Company test for impairment on an annual basis and whenever events or circumstances dictate. Goodwill is allocated among and evaluated for impairment at the reporting unit level, which is defined as an operating segment or one level below an operating segment.
	ASC Topic 350 provides an entity the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (more than 50%) that the estimated fair value of a reporting unit is less than its carrying amount. If an entity elects to perform a qualitative assessment and determines that an impairment is more likely than not, the entity is then required to perform the existing two-step quantitative impairment test (described below), otherwise no further analysis is required. An entity also may elect not to perform the qualitative assessment and, instead, proceed directly to the two-step quantitative impairment test. The ultimate outcome of the goodwill impairment review for a reporting unit should be the same whether an entity chooses to perform the qualitative assessment or proceeds directly to the two-step quantitative impairment test. The Company has a policy for its annual review of goodwill to perform the qualitative assessment for all reporting units not subjected directly to the two-step quantitative impairment test.
	Under the qualitative assessment, various events and circumstances (or factors) that would affect the estimated fair value of a reporting unit are identified (similar to impairment indicators). These factors are then classified by the type of impact they would have on the estimated fair value using positive, neutral, and adverse categories based on current business conditions. Furthermore, the Company considers the results of the most recent two-step quantitative impairment test completed for a reporting unit and compares, among other factors, the weighted average cost of capital ("WACC") between the current and prior years for each reporting unit.
	During the 2014 annual goodwill impairment test, the Company performed the two-step quantitative impairment test for all but one of the reporting units, including those which would qualify for the qualitative assessment. The quantitative impairment tests were performed to establish a current quantitative test for all reporting units which will used as bases for future qualitative assessments.
	For the qualitative assessment performed on the one reporting unit, the Company concluded that it was more likely than not that the estimated fair value of reporting unit was more than its carrying value. As such, no further analysis was required.
	Under the two-step quantitative impairment test, the evaluation of impairment involves comparing the current fair value of each reporting unit to its carrying value, including goodwill. The Company uses weighted results from the discounted cash flow model ("DCF model") and guideline public company method ("Market Approach model") to estimate the current fair value of its reporting units when testing for impairment, as management believes forecasted cash flows and EBITDA are the best indicator of such fair value. A number of significant assumptions and estimates are involved in the application of the DCF model to forecast operating cash flows, including sales volumes and gross margins, tax rates, capital spending, discount rates and working capital changes. Most of these assumptions vary significantly among the reporting units. Significant assumptions in the Market Approach model are projected EBITDA, selected market multiple, and the estimated control premium.
	In the event the estimated fair value of a reporting unit is less than the carrying value, additional analysis is required. The additional analysis would compare the carrying amount of the reporting unit's goodwill with the implied fair value of that goodwill. The implied fair value of goodwill is the excess of the fair value of the reporting unit over the fair value amounts assigned to all of the assets and liabilities of that unit as if the reporting unit was acquired in a business combination and the fair value of the reporting unit represented the purchase price. If the carrying value of goodwill exceeds its implied fair value, an impairment loss equal to such excess would be recognized.
	No impairment charges were recorded as a result of the 2014 goodwill impairment test. During the 2013 annual goodwill impairment test, the Company completed the two-step quantitative impairment test for nine reporting units. As a result, the Company recorded a non-cash goodwill impairment charge of $18.4 million with respect to the epay Australia and epay Spain reporting units.
	During the 2012 annual goodwill impairment test, the Company completed the two-step quantitative impairment test for eight reporting units. As a result, the Company recorded a non-cash goodwill impairment charge of $23.5 million with respect to the epay Brazil reporting unit.
	Other Intangibles - In accordance with ASC Topic 350, intangible assets with finite lives are amortized over their estimated useful lives. Unless otherwise noted, amortization is calculated using the straight-line method over the estimated useful lives of the assets as follows:
	Non-compete agreements	2 - 5 years
	Trademarks and trade names	2 - 20 years
	Software	3 - 10 years
	Customer relationships	6 - 12 years
	The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If such events or changes in circumstances are present, a loss is recognized if the carrying value of the asset is in excess of the sum of the undiscounted cash flows expected to result from the use of the asset and its eventual disposition. An impairment loss is measured as the amount by which the carrying amount of the asset exceeds the fair value of the asset. During 2012, the Company recorded a non-cash impairment charge of $5.2 million with respect to the customer relationships of the epay Brazil business. No impairment of long-lived assets was recorded during 2014 or 2013.
	See Note 8, Goodwill and Acquired Intangible Assets, Net, for additional information regarding the impairment of goodwill and other intangible assets.
Other assets policy [Policy Text Block]	Other assets
	Other assets include deferred financing costs, investments in unconsolidated affiliates, capitalized software development costs and capitalized payments for new or renewed contracts, contract renewals and customer conversion costs. Deferred financing costs represent expenses incurred to obtain financing that have been deferred and are being amortized over the life of the loan. Euronet capitalizes initial payments for new or renewed contracts to the extent recoverable through future operations, contractual minimums and/or penalties in the case of early termination. The Company's accounting policy is to limit the amount of capitalized costs for a given contract to the lesser of the estimated ongoing net future cash flows related to the contract or the termination fees the Company would receive in the event of early termination of the contract by the customer.
	The Company accounts for investments in affiliates using the equity method of accounting when it has the ability to exercise significant influence over the affiliate. Equity losses in affiliates are generally recognized until the Company's investment is zero. In July 2013, the Company completed the sale of its investment in epay Malaysia for $7.6 million, which resulted in the recognition of a $2.8 million gain. As of December 31, 2014 and 2013, the Company had no material investments in unconsolidated affiliates.
Debt, Policy [Policy Text Block]	Convertible notes
	The Company accounts for its convertible debt instruments that may be settled in cash upon conversion in accordance with ASC Topic 470, Debt, which requires the proceeds from the issuance of such convertible debt instruments to be allocated between debt and equity components so that debt is discounted to reflect the Company's nonconvertible debt borrowing rate. Further, the Company applies ASC 470-20-35-13, which requires the debt discount to be amortized over the period the convertible debt is expected to be outstanding as additional non-cash interest expense.
Consolidation, Policy [Policy Text Block]	Noncontrolling interests
	The Company accounts for noncontrolling interests in its consolidated financial statements according to ASC Topic 810, Consolidations, which requires noncontrolling interests to be reported as a component of equity.
Business Combinations Policy [Policy Text Block]	Business combinations
	The Company accounts for business combinations in accordance with ASC Topic 805, Business Combinations, which requires most identifiable assets, liabilities, noncontrolling interests and goodwill acquired in a business combination to be recorded at “full fair value” at the acquisition date. Additionally, ASC Topic 805 requires transaction-related costs to be expensed in the period incurred.
Income Tax, Policy [Policy Text Block]	Income taxes
	Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
	In accordance with ASC Topic 740, Income Taxes, the Company's policy is to record estimated interest and penalties related to the underpayment of income taxes as income tax expense in the Consolidated Statements of Income. See Note 13, Taxes, for further discussion regarding these provisions.
Presentation of taxes collected and remitted to government authorities policy [Policy Text Block]	Presentation of taxes collected and remitted to governmental authorities
	The Company presents taxes collected and remitted to governmental authorities on a net basis in the accompanying Consolidated Statements of Income.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair value measurements
	The Company applies the provisions of ASC Topic 820, Fair Value Measurements and Disclosures, regarding fair value measurements for assets and liabilities. ASC Topic 820 defines fair value, establishes a framework for measuring fair value and requires certain disclosures about fair value measurements. The provisions apply whenever other accounting pronouncements require or permit fair value measurements. See Note 17, Financial Instruments and Fair Value Measurements, for the required fair value disclosures.

	The Company accounts for derivative instruments and hedging activities in accordance with ASC Topic 815, Derivatives and Hedging, which requires that all derivative instruments be recognized as either assets or liabilities on the balance sheet at fair value. Primarily in the Money Transfer Segment, the Company enters into foreign currency derivative contracts, mainly forward contracts, to offset foreign currency exposure related to the notional value of money transfer settlement assets and liabilities in currencies other than the U.S. dollar. These contracts are considered derivative instruments under the provisions of ASC Topic 815; however, the Company does not designate such instruments as hedges for accounting purposes. Accordingly, changes in the value of these contracts are recognized immediately as a component of foreign currency exchange gain (loss), net in the Consolidated Statements of Income. The impact of changes in value of these contracts, together with the impact of the change in value of the related foreign currency denominated settlement asset or liability, on the Company's Consolidated Statements of Income and Consolidated Balance Sheets is not significant.
	Cash flows resulting from derivative instruments are included in operating activities in the Company's Consolidated Statements of Cash Flows. The Company enters into derivative instruments with highly credit-worthy financial institutions and does not use derivative instruments for trading or speculative purposes. See Note 11, Derivative Instruments and Hedging Activities, for further discussion of derivative instruments.
Revenue Recognition, Policy [Policy Text Block]	Revenue recognition
	The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed or determinable and collection is reasonably assured. The majority of the Company's revenues are comprised of monthly recurring management fees and transaction-based fees. A description of the major components of revenue by business segment is as follows:
	EFT Processing - Revenues in the EFT Processing Segment are primarily derived from transaction and management fees and foreign currency exchange margin from owned and outsourced ATM, POS and card processing networks and from the sale of EFT software solutions for electronic payment and transaction delivery systems, and fees or margin earned from value added services, including dynamic currency conversion.
	Transaction-based fees include charges for cash withdrawals, debit or credit card transactions, balance inquiries, transactions not completed because the relevant card issuer does not give authorization and prepaid mobile airtime recharges. Outsourcing services are generally billed on the basis of a fixed monthly fee per ATM, plus a transaction-based fee. Transaction-based fees are recognized at the time the transactions are processed and outsourcing management fees are recognized ratably over the contract period.
	Certain of the Company's non-cancelable customer contracts provide for the receipt of up-front fees from the customer and/or decreasing or increasing fee schedules over the agreement term for substantially the same level of services to be provided by the Company. The Company recognizes revenue under these contracts based on proportional performance of services over the term of the contract. This generally results in “straight-line” (i.e., consistent value per period) revenue recognition of the contracts' total cash flows, including any up-front payment received from the customer.
	Revenues from the sale of EFT software solutions represent software license fees, professional installation and customization fees, ongoing software maintenance fees, hardware sales and transaction fees. The Company recognizes professional service fee revenue in accordance with the provisions of ASC Topic 985, Software and ASC Topic 605, Revenue Recognition. ASC Topic 985 generally requires revenue earned on software arrangements involving multiple elements to be allocated to each element based on the relative fair values of those elements.
	Revenues from software licensing agreement contracts are recognized over the professional services portion of the contract term using the percentage-of-completion method, following the guidance in ASC Topic 605, as prescribed by ASC Topic 985. Software maintenance revenue is recognized over the contractual period or as the maintenance-related service is performed. Revenues from the sale of hardware are generally recognized when title passes to the customer.
	epay - Revenue generated in the epay Segment is primarily derived from commissions or processing fees associated with distribution and/or processing of prepaid mobile airtime and other electronic payment products. These fees and commissions are received from mobile phone and other telecommunication operators, top-up distributors, other product vendors or distributors or from retailers. In accordance with ASC Topic 605, commissions received are recognized as revenue during the period in which the Company provides the service. The portion of the commission that is paid to retailers is generally recorded as a direct operating cost. However, in circumstances where the Company is not the primary obligor in the distribution of the electronic payment products, those commissions are recorded as a reduction of revenue. In selling certain products, the Company is the primary obligor in the arrangements; accordingly, the gross sales value of the products are recorded as revenue and the purchase cost as direct operating cost. Transactions are processed through a network of POS terminals and direct connections to the electronic payment systems of retailers. Transaction processing fees are recognized at the time the transactions are processed.
	Money Transfer - In accordance with ASC Topic 605, revenues for money transfer and other services represent a transaction fee in addition to a margin earned from purchasing currency at wholesale exchange rates and selling the currency to customers at retail exchange rates. Revenues and the associated direct operating cost are recognized at the time the transaction is processed. The Company has origination and distribution agents in place, which each earn a fee for the respective service. These fees are reflected as direct operating costs.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Share-based compensation
	The Company follows the provisions of ASC Topic 718, Compensation - Stock Compensation, for equity classified awards, which requires the determination of the fair value of the share-based compensation at the grant date and subsequent recognition of the related expense over the period in which the share-based compensation is earned (“requisite service period”).
	The amount of future compensation expense related to awards of nonvested shares or nonvested share units (“restricted stock”) is based on the market price for Euronet Common Stock at the grant date. The grant date is the date at which all key terms and conditions of the grant have been determined and the Company becomes contingently obligated to transfer equity to the employee who renders the requisite service, generally the date at which grants are approved by the Company's Board of Directors or Compensation Committee thereof. Share-based compensation expense for awards with only service conditions is generally recognized as expense on a “straight-line” basis over the requisite service period. For awards that vest based on achieving periodic performance conditions, expense is recognized on a “graded attribution method.” The graded attribution method results in expense recognition on a straight-line basis over the requisite service period for each separately vesting portion of an award. The Company has elected to use the “with and without method” when calculating the income tax benefit associated with its share-based payment arrangements. See Note 15, Stock Plans, for further disclosure.
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Recently issued and adopted accounting pronouncements
	Recently Issued - In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard will become effective for the Company on January 1, 2017 and early adoption is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.
	Recently Adopted - In July 2013, the FASB issued Accounting Standards Update No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists ("ASU 2013-11"). The amendments in ASU 2013-11 provide guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The Company adopted ASU 2013-11 as of January 1, 2014, and its adoption did not have a material impact on the Company's results of operations, cash flows or financial position.
