Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements for the three and six months ended June 30, 2019 and 2018 are unaudited. In the opinion of management, all adjustments necessary for a fair presentation of the consolidated financial statements have been included. Such adjustments consisted of normal recurring items. Interim results are not necessarily indicative of results for a full year. The consolidated financial statements and accompanying notes are presented as permitted by Form 10-Q and do not contain certain information included in the annual consolidated financial statements and accompanying notes of Fiserv, Inc. (the “Company”). These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 . Certain prior period amounts have been reclassified to conform to current period presentation. Effective January 1, 2019, the Company adopted Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) (“ASU 2016-02” ) , and its related amendments using the optional transition method applied to all leases. Prior period amounts have not been restated. Additional information about the Company’s lease policies and the related impact of the adoption is included in Notes 2 and 14 to the consolidated financial statements. Principles of Consolidation The consolidated financial statements include the accounts of Fiserv, Inc. and all 100% owned subsidiaries. Investments in less than 50% owned affiliates in which the Company has significant influence but not control are accounted for using the equity method of accounting. All intercompany transactions and balances have been eliminated in consolidation.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In June 2018, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018-07”), which simplifies the accounting for share-based payments granted to nonemployees by largely aligning it with the accounting for share-based payments to employees. For public entities, ASU 2018-07 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Entities must apply the standard, using a modified retrospective transition approach, with a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption for all liability-classified nonemployee awards that have not been settled as of the adoption date and equity-classified nonemployee awards for which a measurement date has not been established. The Company adopted ASU 2018-07 on January 1, 2019, and the adoption did not have any impact on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, which requires lessees to recognize a lease liability and a right-of-use asset for each lease with a term longer than twelve months. The recognized liability is measured at the present value of lease payments not yet paid, and the corresponding asset represents the lessee’s right to use the underlying asset over the lease term and is based on the liability, subject to certain adjustments. For income statement and statement of cash flow purposes, the standard retains the dual model with leases classified as either operating or finance. Operating leases result in straight-line expense while finance leases result in a front-loaded expense pattern. The standard prescribes a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. ASU 2016-02 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842 ; ASU No. 2018-10, Codification Improvements to Topic 842 ; ASU No. 2018-11, Leases (Topic 842) - Targeted Improvements ; ASU No. 2018-20, Narrow-Scope Improvements for Lessors; and ASU No. 2019-01, Leases (Topic 842) - Codification Improvements . ASU No. 2018-11 provides an additional transition method allowing entities to initially apply the new lease standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. For public entities, ASU 2016-02 is effective for annual and interim periods beginning after December 15, 2018. The Company adopted the new standard effective January 1, 2019 using the optional transition method in ASU No. 2018-11. Under this method, the Company has not adjusted its comparative period financial statements for the effects of the new standard or made the new, expanded required disclosures for periods prior to the effective date. The Company elected the package of practical expedients permitted under the transition guidance in ASU 2016-02 to not reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs. The Company also elected the practical expedient not to separate the non-lease components of a contract from the lease component to which they relate. The adoption of the new lease standard resulted in the recognition of lease liabilities of $383 million and right-of-use assets of $343 million , which include the impact of existing deferred rents and tenant improvement allowances on the consolidated balance sheet as of January 1, 2019 for real and personal property operating leases. The adoption of ASU 2016-02 did not have a material impact on the Company’s consolidated statements of income or consolidated statements of cash flows. Recently Issued Accounting Pronouncements In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (“ASU 2018-15”), which aligns the requirements for capitalizing implementation costs incurred in a cloud computing hosting arrangement that is a service contract with the requirements under Accounting Standards Codification (“ASC”) 350 for capitalizing implementation costs incurred to develop or obtain internal-use software. For public entities, ASU 2018-15 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019, with early adoption permitted. Entities are permitted to apply either a retrospective or prospective transition approach to adopt the guidance. The Company plans to adopt ASU 2018-15 on January 1, 2020 and does not expect the adoption to have a material impact on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which removes, modifies, and adds certain disclosure requirements of ASC Topic 820, Fair Value Measurement . ASU 2018-13 is effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2019, with the additional disclosures required to be applied prospectively and the modified and removed disclosures required to be applied retrospectively to all periods presented. Entities are permitted to early adopt the removed or modified disclosures and delay the adoption of the additional disclosures until the effective date. The Company is currently assessing the impact that the adoption of ASU 2018-13 will have on its consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) (“ASU 2016-13”), which prescribes an impairment model for most financial instruments based on expected losses rather than incurred losses. Under this model, an estimate of expected credit losses over the contractual life of the instrument is to be recorded as of the end of a reporting period as an allowance to offset the amortized cost basis, resulting in a net presentation of the amount expected to be collected on the financial instrument. For public entities, ASU 2016-13 is effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. For most instruments, entities must apply the standard using a cumulative-effect adjustment to beginning retained earnings as of the beginning of the fiscal year of adoption. The Company is currently assessing the impact that the adoption of ASU 2016-13 will have on its consolidated financial statements.

Revenue Recognition

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The Company generates revenue from the delivery of processing, service and product solutions. Revenue is measured based on consideration specified in a contract with a customer, and excludes any amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer which may be at a point in time or over time. Disaggregation of Revenue The tables below present the Company’s revenue disaggregated by major business, including a reconciliation with its reportable segments. Most of the Company’s revenue is earned domestically within these major businesses, with revenue from clients outside the United States comprising approximately 6% and 5% of total revenue for the six months ended June 30, 2019 and 2018 , respectively.

(In millions) June 30, 2019 December 31, 2018 Contract assets $ 204 $ 171 Contract liabilities 466 469 Contract assets, reported within other long-term assets in the consolidated balance sheets, primarily result from revenue being recognized where payment is contingent upon the transfer of services to a customer over the contractual period. Contract liabilities primarily relate to advance consideration received from customers (deferred revenue) for which transfer of control occurs, and therefore revenue is recognized, as services are provided. Contract balances are reported in a net contract asset or liability position on a contract-by-contract basis at the end of each reporting period. The Company recognized $248 million of revenue during the six months ended June 30, 2019 that was included in the contract liability balance at the beginning of the period, which exceeded advance cash receipts for services yet to be provided. Transaction Price Allocated to Remaining Performance Obligations The following table includes estimated revenue expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied) at the end of the reporting period. (In millions) Remainder of: June 30, 2019 2019 2020 2021 2022 Thereafter Processing and services $ 549 $ 943 $ 772 $ 560 $ 746 Product 16 31 22 12 11 The Company applies the optional exemption in paragraph 606-10-50-14(b) and does not disclose information about remaining performance obligations for account- and transaction-based processing fees that qualify for recognition in accordance with paragraph 606-10-55-18. These contracts generally have terms of three to five years , and contain variable consideration for stand-ready performance obligations for which the exact quantity and mix of transactions to be processed are contingent upon the customer’s request. The Company also applies the optional exemptions in paragraph 606-10-50-14A and does not disclose information for variable consideration, including additional seat licenses, that is a sales-based or usage-based royalty promised in exchange for a license of intellectual property or that is allocated entirely to a wholly unsatisfied performance obligation or to a wholly unsatisfied promise to transfer a distinct good or service in a series. The amounts disclosed above as remaining performance obligations consist primarily of fixed or monthly minimum processing fees and maintenance fees under contracts with an original expected duration of greater than one year.

Business Combinations [Abstract]
Acquisitions	Acquisitions On October 31, 2018, the Company acquired the debit card processing, ATM Managed Services, and MoneyPass® surcharge-free network of Elan Financial Services, a unit of U.S. Bancorp (“Elan”), for approximately $659 million . Such purchase price includes an initial cash payment of $691 million , less the receipt of post-closing working capital adjustments of $57 million in 2019 , plus contingent consideration related to earn-out provisions estimated at a fair value of $12 million and future payments under a transition services agreement estimated to be in excess of fair value of $13 million . This acquisition, included within the Payments segment, deepens the Company’s presence in debit card processing, broadens its client reach and scale, and provides new solutions to enhance the value proposition for its existing debit solution clients. The preliminary allocation of purchase price recorded for Elan as of June 30, 2019 was as follows: (In millions) Trade accounts receivable $ 20 Prepaid expenses and other current assets 94 Property and equipment 9 Intangible assets 353 Goodwill 238 Accounts payable and other current liabilities (55 ) Total purchase price $ 659 The amounts allocated to goodwill and intangible assets were based on preliminary valuations and are subject to final adjustment. Goodwill, expected to be deductible for tax purposes, is primarily attributed to synergies, including the migration of Elan’s clients to the Company’s debit platform, and the anticipated value created by selling the Company’s products and services outside of card payments to Elan’s existing client base. The values allocated to intangible assets are as follows: (In millions) Gross Carrying Amount Weighted-Average Useful Life Customer related intangible assets $ 350 15 years Trade name 3 8 years $ 353 15 years In conjunction with the acquisition, the Company entered into a transition services agreement for the provision of certain processing, network, administrative and managed services for a period of two years . The results of operations for Elan consisting of $45 million and $91 million of revenue and $5 million and $14 million of operating income, including $6 million and $12 million of acquired intangible asset amortization, for the three and six months ended June 30, 2019 , respectively, have been included within the accompanying consolidated statements of income. On January 16, 2019, the Company announced that it had entered into a definitive merger agreement to acquire First Data Corporation (“First Data”) in an all-stock transaction for an equity value of approximately $22 billion as of the announcement. Fiserv and First Data have received the final required regulatory approvals and non-objections needed to complete the proposed acquisition. Subject to the satisfaction or waiver of the remaining customary contractual conditions set forth in the merger agreement, the parties expect to close the transaction on or about July 29, 2019. See Note 13 for a description of related debt financing activities.

The Lending Joint Ventures, which were reported within the Financial segment, included all of the Company’s automotive loan origination and servicing products, as well as its LoanServ TM mortgage and consumer loan servicing platform. The Company received gross sale proceeds of $419 million from the transactions. During the six months ended June 30, 2018 , the Company recognized a pre-tax gain on the sale of $229 million , with the related tax expense of $77 million recorded through the income tax provision, in the consolidated statements of income. The pre-tax gain included $124 million related to the remeasurement of the Company’s 45% retained interests based upon the estimated enterprise value of the Lending Joint Ventures. During the six months ended June 30, 2019 , the Company recognized a pre-tax gain on the sale of $10 million , with the related tax expense of $2 million recorded through the income tax provision, as contingent special distribution provisions within the transaction agreement were resolved and thereby realized. The Company’s remaining 45% ownership interests in the Lending Joint Ventures are accounted for as equity method investments, with the Company’s share of net (loss) income reported as (loss) income from investments in unconsolidated affiliates and the related tax (benefit) expense reported within the income tax provision in the consolidated statements of income. During the three months ended June 30, 2019 , the Company received a cash distribution of $7 million from the Lending Joint Ventures, which was recorded as a reduction in the Company’s investment in the Lending Joint Ventures. The entire distribution represented a return of the Company’s investment and is reported in cash flows from investing activities. The Company’s investment in the Lending Joint Ventures was $48 million and $65 million at June 30, 2019 and December 31, 2018 , respectively, and is reported within other long-term assets in the consolidated balance sheets. The revenues, expenses and cash flows of the Lending Joint Ventures after the sale transactions are not included in the Company’s consolidated financial statements. Prior to the sale transactions described above, the Lending Joint Ventures entered into variable-rate term loan facilities for an aggregate amount of $350 million in senior unsecured debt and variable-rate revolving credit facilities for an aggregate amount of $35 million with a syndicate of banks, which transferred to the Lending Joint Ventures as part of the sale. The Company has guaranteed this debt of the Lending Joint Ventures and does not anticipate that the Lending Joint Ventures will fail to fulfill their debt obligations. These debt facilities mature in March 2023, and there are no outstanding borrowings on the revolving credit facilities as of June 30, 2019 . The Company recorded an initial $34 million liability as a reduction to the gain on sale transactions for the estimated fair value of its obligations to stand ready to perform over the term of the guarantees, which is reported primarily within other long-term liabilities in the consolidated balance sheets. Such guarantees will be amortized in future periods over the contractual term. The Company recognized $2 million during both the three months ended June 30, 2019 and 2018, and $3 million and $2 million during the six months ended June 30, 2019 and 2018, respectively, within non-operating income in its consolidated statements of income related to its release from risk under the guarantees. The Company has not made any payments under the guarantees, nor has it been called upon to do so. In conjunction with the sale transactions described above, the Company also entered into certain transition services agreements to provide, at fair value, various administration, business process outsourcing, technical and data center related services for defined periods to the Lending Joint Ventures. Amounts transacted through these agreements approximated $9 million and $18 million during the three and six months ended June 30, 2019 , respectively, and $10 million during the three and six months ended June 30, 2018

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company applies fair value accounting for all assets and liabilities that are recognized or disclosed at fair value in its consolidated financial statements on a recurring basis. Fair value represents the amount that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities, the Company considers the principal or most advantageous market and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability. The fair values of cash equivalents, trade accounts receivable, settlement assets and obligations, accounts payable, and client deposits approximate their respective carrying values due to the short period of time to maturity. The estimated fair value of total debt was based on quoted prices in active markets for the Company’s senior notes (level 1 of the fair value hierarchy). The fair value of the Company’s revolving credit facility borrowings approximates carrying value as the underlying interest rate is variable based on LIBOR. The estimated fair value of total debt was $14.0 billion and $6.0 billion at June 30, 2019 and December 31, 2018 , respectively. See Note 13 for a description of debt financing activities in connection with the Company’s proposed acquisition of First Data. The estimated fair value of the contingent consideration liability of $12 million at June 30, 2019 related to the acquisition of Elan (see Note 4 ) was based on the present value of a probability-weighted assessment approach derived from the likelihood of achieving the earn-out criteria (level 3 of the fair value hierarchy). This estimated fair value has not changed since the acquisition date. The aggregate fair values of the Company’s debt guarantee arrangements (see Note 6) with the Lending Joint Ventures approximate the $26 million carrying values at June 30, 2019 (level 3 of the fair value hierarchy). The contingent consideration and debt guarantee liabilities are reported primarily in other long-term liabilities in the consolidated balance sheets.

Debt Disclosure [Abstract]
Long-term Debt	Long-Term Debt On January 16, 2019, in connection with the definitive merger agreement to acquire First Data (see Note 4), the Company entered into a bridge facility commitment letter pursuant to which a group of financial institutions committed to provide a 364 -day senior unsecured bridge term loan facility in an aggregate principal amount of $17.0 billion for the purpose of refinancing certain indebtedness of First Data and its subsidiaries on the closing date of the merger, making cash payments in lieu of fractional shares as part of the merger consideration, and paying fees and expenses related to the merger, the refinancing and the related transactions. The Company recorded $37 million and $96 million of ex penses, reported within debt financing activities in the consolidated statements of income, related to the bridge term loan facility during the three and six months ended June 30, 2019 , respectively. There were no outstanding borrowings under the bridge term loan facility at June 30, 2019 . The aggregate commitments of $17.0 billion under the bridge facility commitment letter have been replaced with a corresponding amount of permanent financing through the term loan credit agreement and issuance of senior notes, as described below, resulting in the termination of the bridge term loan facility effective July 1, 2019. On February 6, 2019, the Company entered into an amendment to its amended and restated revolving credit facility to (i) amend the maximum leverage ratio covenant to permit it to elect to increase the permitted maximum leverage ratio from three and one-half times the Company’s consolidated net earnings before interest, taxes, depreciation, amortization, non-cash charges and expenses and certain other adjustments (“EBITDA”) to either four times or four and one-half times the Company’s EBITDA for a specified period following certain acquisitions and (ii) permit it to make drawings under the revolving credit facility on the closing date of its acquisition of First Data subject to only limited conditions. In addition, on February 15, 2019, the Company entered into a second amendment to its existing revolving credit agreement in order to increase the aggregate commitments available thereunder by $1.5 billion and to make certain additional amendments to facilitate the operation of the combined business following the acquisition of First Data. The increased commitments and additional amendments related to the revolving credit facility will become effective upon the satisfaction or waiver of conditions that are substantially similar to the conditions to funding under the term loan facility described below. On February 15, 2019, the Company entered into a new term loan credit agreement with a syndicate of financial institutions pursuant to which such financial institutions have committed to provide the Company with a senior unsecured term loan facility in an aggregate principal amount of $5.0 billion , consisting of $1.5 billion in commitments to provide loans with a three-year maturity and $3.5 billion in commitments to provide loans with a five-year maturity. The availability of loans under the term loan facility is subject to the satisfaction or waiver of certain conditions, including (i) the closing of the acquisition substantially concurrently with the funding of such loans, (ii) the absence of a material adverse effect with respect to First Data since January 16, 2019, (iii) the truth and accuracy in all material respects of certain representations and warranties, (iv) the receipt of certain certificates, and (v) the receipt of certain financial statements. Loans drawn under the term loan facility will be subject to amortization at an annual rate of 5% for the first two years and 7.5% thereafter (with loans outstanding under the five-year tranche subject to amortization at an annual rate of 10% after the fourth anniversary of the commencement of amortization), with accrued and unpaid amortization amounts required to be paid on the last business day in December of each year. Borrowings under the term loan facility will bear interest at variable rates based on LIBOR or on a base rate plus, in each case, a specified margin based on the Company’s long-term debt rating in effect from time to time. The Company is also required to pay a ticking fee that accrues on the aggregate undrawn commitments under the term loan facility at a per annum rate based upon the Company’s long-term debt rating in effect from time to time. The term loan credit agreement contains affirmative, negative and financial covenants, and events of default, that are substantially the same as those set forth in the Company’s existing revolving credit facility, as amended as described above. On June 24, 2019, the Company completed an offering of $9.0 billion aggregate principal amount of senior notes comprised of $2.0 billion aggregate principal amount of 2.75% senior notes due in July 2024, $2.0 billion aggregate principal amount of 3.2% senior notes due in July 2026, $3.0 billion aggregate principal amount of 3.5% senior notes due in July 2029 and $2.0 billion aggregate principal amount of 4.4% senior notes due in July 2049. The senior notes pay interest semi-annually on January 1 and July 1, commencing on January 1, 2020. The indentures governing the senior notes contain covenants that, among other matters, limit (i) the Company’s ability to consolidate or merge with or into, or convey, transfer or lease all or substantially all of its properties and assets to another person, (ii) the Company’s and certain of its subsidiaries’ ability to create or assume liens, and (iii) the Company’s and certain of its subsidiaries’ ability to engage in sale and leaseback transactions. The Company may, at its option, redeem the senior notes, in whole or in part, at any time prior to the applicable par call date. If the proposed merger between the Company and First Data is terminated, has not been consummated, or the Company uses reasonable judgment to determine that the merger will not be consummated, on or prior to April 16, 2020, the Company is required to redeem all outstanding senior notes at a price equal to 101% of the aggregate principal amount plus any accrued and unpaid interest. The Company intends to use the net proceeds of the senior notes to refinance indebtedness in connection with the closing of the merger with First Data and used a portion of the net proceeds from the offering described above to repay all outstanding borrowings totaling $790 million under its amended and restated revolving credit facility pending such use. Remaining proceeds were invested in a highly liquid institutional bank deposit held at a single financial institution and were recorded as cash equivalents on the consolidated balance sheet as of June 30, 2019. In June 2019, the Company entered into an underwriting agreement with a syndicate of financial institutions for the issuance and sale of €1.5 billion aggregate principal amount and £1.05 billion aggregate principal amount of senior notes comprised of €500 million aggregate principal amount of 0.375% senior notes due in July 2023, €500 million aggregate principal amount of 1.125% senior notes due in July 2027, €500 million aggregate principal amount of 1.625% senior notes due in July 2030, £525 million aggregate principal amount of 2.25% senior notes due in July 2025, and £525 million aggregate principal amount of 3.0% senior notes due in July 2031. The Company completed its offering of these senior notes on July 1, 2019, therefore, such senior notes are not reflected within the consolidated balance sheet as of June 30, 2019. The senior notes pay interest annually on July 1, commencing on July 1, 2020. The indentures governing the senior notes contain covenants that are substantially the same as those set forth in the Company’s $9.0 billion aggregate principal amount senior notes described above. In connection with the anticipated issuance of the senior notes described above, the Company entered into foreign exchange forward contracts to minimize foreign currency exposure to the Euro and British Pound upon settlement of the proceeds from the senior notes. At June 30, 2019, the notional amount of these derivatives was £1.05 billion ( $1.34 billion ) and €563 million ( $641 million ), and the fair value totaling $2.0 million was reported in prepaid expenses and other current assets in the consolidated balance sheet and in debt financing activities in the consolidated statement of income as of and during the three months ended June 30, 2019. The foreign exchange forward contracts matured on July 1, 2019, concurrent with the offering of the senior notes described above.

Leases [Abstract]
Leases	Leases The Company adopted ASU 2016-02 and its related amendments (collectively known as “ASC 842”) effective January 1, 2019 using the optional transition method in ASU 2018-11. Therefore, the reported results for the three and six months ended June 30, 2019 reflect the application of ASC 842 while the reported results for the three and six months ended June 30, 2018 were not adjusted and continue to be reported under the accounting guidance, ASC 840, Leases (“ASC 840”), in effect for the prior periods. The Company determines if an arrangement is a lease at inception. The lease term begins on the commencement date, which is the date the Company takes possession of the property, and may include options to extend or terminate the lease when it is reasonably certain that the option will be exercised. The lease term is used to determine lease classification as an operating or finance lease and is used to calculate straight-line lease expense for operating leases. The Company elected the package of practical expedients permitted under the transition guidance within ASU 2016-02 to not reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs. Right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. As a practical expedient, lease agreements with lease and non-lease components are accounted for as a single lease component for all asset classes, which are comprised of real estate leases and equipment leases. ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. ROU assets also include prepaid lease payments and exclude lease incentives received. The Company estimates contingent lease incentives when it is probable that the Company is entitled to the incentive at lease commencement. As the Company’s leases typically do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date for both real estate and equipment leases. The determination of the incremental borrowing rate requires judgment. The Company determines the incremental borrowing rate using the Company’s current unsecured borrowing rate, adjusted for various factors such as collateralization and term to align with the terms of the lease. The Company elected the short-term lease recognition exemption for all leases that qualify. Therefore, leases with an initial term of 12 months or less are not recorded on the balance sheet; instead, lease payments are recognized as lease expense on a straight-line basis over the lease term. The Company leases certain office space, data centers, and equipment. The Company’s leases have remaining lease terms of one to 11 years . Most leases contain renewal options for varying periods, which are at the Company’s sole discretion. For leases where the Company is reasonably certain to exercise a renewal option, such option periods have been included in the determination of the Company’s ROU assets and lease liabilities. Certain leases require the Company to pay taxes, insurance, maintenance, and other operating expenses associated with the leased asset. Such amounts are not included in the measurement of the lease liability to the extent they are variable in nature. These variable lease costs are recognized as a variable lease expense when incurred. Certain leases include options to purchase the leased asset at the end of the lease term, which is assessed as a part of the Company’s lease classification determination. The depreciable life of the ROU assets and leasehold improvements are limited by the expected lease term unless the Company is reasonably certain of a transfer of title or purchase option.

Accounting Policies [Abstract]
Principles of Consolidation, Policy	Principles of Consolidation The consolidated financial statements include the accounts of Fiserv, Inc. and all 100% owned subsidiaries. Investments in less than 50% owned affiliates in which the Company has significant influence but not control are accounted for using the equity method of accounting. All intercompany transactions and balances have been eliminated in consolidation.
Recently Adopted And Issued Accounting Pronouncements, Policy	Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In June 2018, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018-07”), which simplifies the accounting for share-based payments granted to nonemployees by largely aligning it with the accounting for share-based payments to employees. For public entities, ASU 2018-07 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Entities must apply the standard, using a modified retrospective transition approach, with a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption for all liability-classified nonemployee awards that have not been settled as of the adoption date and equity-classified nonemployee awards for which a measurement date has not been established. The Company adopted ASU 2018-07 on January 1, 2019, and the adoption did not have any impact on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, which requires lessees to recognize a lease liability and a right-of-use asset for each lease with a term longer than twelve months. The recognized liability is measured at the present value of lease payments not yet paid, and the corresponding asset represents the lessee’s right to use the underlying asset over the lease term and is based on the liability, subject to certain adjustments. For income statement and statement of cash flow purposes, the standard retains the dual model with leases classified as either operating or finance. Operating leases result in straight-line expense while finance leases result in a front-loaded expense pattern. The standard prescribes a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. ASU 2016-02 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842 ; ASU No. 2018-10, Codification Improvements to Topic 842 ; ASU No. 2018-11, Leases (Topic 842) - Targeted Improvements ; ASU No. 2018-20, Narrow-Scope Improvements for Lessors; and ASU No. 2019-01, Leases (Topic 842) - Codification Improvements . ASU No. 2018-11 provides an additional transition method allowing entities to initially apply the new lease standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. For public entities, ASU 2016-02 is effective for annual and interim periods beginning after December 15, 2018. The Company adopted the new standard effective January 1, 2019 using the optional transition method in ASU No. 2018-11. Under this method, the Company has not adjusted its comparative period financial statements for the effects of the new standard or made the new, expanded required disclosures for periods prior to the effective date. The Company elected the package of practical expedients permitted under the transition guidance in ASU 2016-02 to not reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs. The Company also elected the practical expedient not to separate the non-lease components of a contract from the lease component to which they relate. The adoption of the new lease standard resulted in the recognition of lease liabilities of $383 million and right-of-use assets of $343 million , which include the impact of existing deferred rents and tenant improvement allowances on the consolidated balance sheet as of January 1, 2019 for real and personal property operating leases. The adoption of ASU 2016-02 did not have a material impact on the Company’s consolidated statements of income or consolidated statements of cash flows. Recently Issued Accounting Pronouncements In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (“ASU 2018-15”), which aligns the requirements for capitalizing implementation costs incurred in a cloud computing hosting arrangement that is a service contract with the requirements under Accounting Standards Codification (“ASC”) 350 for capitalizing implementation costs incurred to develop or obtain internal-use software. For public entities, ASU 2018-15 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019, with early adoption permitted. Entities are permitted to apply either a retrospective or prospective transition approach to adopt the guidance. The Company plans to adopt ASU 2018-15 on January 1, 2020 and does not expect the adoption to have a material impact on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which removes, modifies, and adds certain disclosure requirements of ASC Topic 820, Fair Value Measurement . ASU 2018-13 is effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2019, with the additional disclosures required to be applied prospectively and the modified and removed disclosures required to be applied retrospectively to all periods presented. Entities are permitted to early adopt the removed or modified disclosures and delay the adoption of the additional disclosures until the effective date. The Company is currently assessing the impact that the adoption of ASU 2018-13 will have on its consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) (“ASU 2016-13”), which prescribes an impairment model for most financial instruments based on expected losses rather than incurred losses. Under this model, an estimate of expected credit losses over the contractual life of the instrument is to be recorded as of the end of a reporting period as an allowance to offset the amortized cost basis, resulting in a net presentation of the amount expected to be collected on the financial instrument. For public entities, ASU 2016-13 is effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. For most instruments, entities must apply the standard using a cumulative-effect adjustment to beginning retained earnings as of the beginning of the fiscal year of adoption. The Company is currently assessing the impact that the adoption of ASU 2016-13 will have on its consolidated financial statements.
Revenue from Contract with Customer, Policy	The Company applies the optional exemption in paragraph 606-10-50-14(b) and does not disclose information about remaining performance obligations for account- and transaction-based processing fees that qualify for recognition in accordance with paragraph 606-10-55-18. These contracts generally have terms of three to five years , and contain variable consideration for stand-ready performance obligations for which the exact quantity and mix of transactions to be processed are contingent upon the customer’s request. The Company also applies the optional exemptions in paragraph 606-10-50-14A and does not disclose information for variable consideration, including additional seat licenses, that is a sales-based or usage-based royalty promised in exchange for a license of intellectual property or that is allocated entirely to a wholly unsatisfied performance obligation or to a wholly unsatisfied promise to transfer a distinct good or service in a series. The amounts disclosed above as remaining performance obligations consist primarily of fixed or monthly minimum processing fees and maintenance fees under contracts with an original expected duration of greater than one year. Contract assets, reported within other long-term assets in the consolidated balance sheets, primarily result from revenue being recognized where payment is contingent upon the transfer of services to a customer over the contractual period. Contract liabilities primarily relate to advance consideration received from customers (deferred revenue) for which transfer of control occurs, and therefore revenue is recognized, as services are provided. Contract balances are reported in a net contract asset or liability position on a contract-by-contract basis at the end of each reporting period. The Company generates revenue from the delivery of processing, service and product solutions. Revenue is measured based on consideration specified in a contract with a customer, and excludes any amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer which may be at a point in time or over time.
Leases, Policy	The Company determines if an arrangement is a lease at inception. The lease term begins on the commencement date, which is the date the Company takes possession of the property, and may include options to extend or terminate the lease when it is reasonably certain that the option will be exercised. The lease term is used to determine lease classification as an operating or finance lease and is used to calculate straight-line lease expense for operating leases. The Company elected the package of practical expedients permitted under the transition guidance within ASU 2016-02 to not reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs. Right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. As a practical expedient, lease agreements with lease and non-lease components are accounted for as a single lease component for all asset classes, which are comprised of real estate leases and equipment leases. ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. ROU assets also include prepaid lease payments and exclude lease incentives received. The Company estimates contingent lease incentives when it is probable that the Company is entitled to the incentive at lease commencement. As the Company’s leases typically do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date for both real estate and equipment leases. The determination of the incremental borrowing rate requires judgment. The Company determines the incremental borrowing rate using the Company’s current unsecured borrowing rate, adjusted for various factors such as collateralization and term to align with the terms of the lease. The Company elected the short-term lease recognition exemption for all leases that qualify. Therefore, leases with an initial term of 12 months or less are not recorded on the balance sheet; instead, lease payments are recognized as lease expense on a straight-line basis over the lease term. The Company leases certain office space, data centers, and equipment. The Company’s leases have remaining lease terms of one to 11 years . Most leases contain renewal options for varying periods, which are at the Company’s sole discretion. For leases where the Company is reasonably certain to exercise a renewal option, such option periods have been included in the determination of the Company’s ROU assets and lease liabilities. Certain leases require the Company to pay taxes, insurance, maintenance, and other operating expenses associated with the leased asset. Such amounts are not included in the measurement of the lease liability to the extent they are variable in nature. These variable lease costs are recognized as a variable lease expense when incurred. Certain leases include options to purchase the leased asset at the end of the lease term, which is assessed as a part of the Company’s lease classification determination. The depreciable life of the ROU assets and leasehold improvements are limited by the expected lease term unless the Company is reasonably certain of a transfer of title or purchase option.
