Accounting Policies [Abstract]
Nature of Operations and Summary of Significant Accounting Policies	1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Nature of Operations
	Mitek Systems, Inc. (the “Company”) is engaged in the development, sale and service of its proprietary software solutions related to mobile capture and identity authentication.
	The Company applies its patented technology in image capture, correction and intelligent data extraction in the mobile financial and business services markets. The Company’s technology allows users to remotely deposit checks, pay bills, transfer credit card balances, open accounts and get insurance quotes by taking pictures of various documents with their camera-equipped smartphones and tablets instead of using the device keyboard. The Company’s products use advanced algorithms to correct image distortion, extract relevant data, route images to their desired location and process transactions through users’ financial institutions. As of March 31, 2015, the Company has been granted 21 patents and has an additional 21 patent applications pending.
	The Company’s products enable deposits, confirm identity and accelerate payments for mobile transactions.
	Deposit
	The Company’s Mobile Deposit® and Commercial Mobile Deposit Capture™ products are software that allows consumers and businesses to remotely deposit checks using their camera-equipped smartphone or tablet. As of March 31, 2015, 3,705 financial institutions have signed agreements to deploy Mobile Deposit® and 3,181 of these financial institutions have deployed Mobile Deposit® to their consumers, including all of the top ten, and  nearly all  of the top 50, U.S. retail banks, as ranked by SNL Financial for the fourth quarter of calendar year 2014. Commercial Mobile Deposit Capture™ utilizes the same technology as Mobile Deposit®, but has additional capabilities specifically designed to meet the needs of business users such as invoice capture.
	Identity
	The Company’s identity offerings feature Mobile Photo Account Opening™ which allows a consumer to take a photo of his or her driver’s license or other identity document to pre-fill mobile application forms on a mobile device. The Company’s identity offerings are currently in early deployment with large banks and insurance companies where they help consumers to open new financial accounts or get competitive rate quotes. Mobile Photo Account Opening™ can be used by bank personnel (both in-branch or at a community event) as well as by consumers on their mobile device (both native app or mobile web).
	Payment
	The Company’s mobile photo payment solutions enable mobile bill payment for financial institutions and organizations that bill consumers directly.
	Mobile Photo Bill Pay® is for financial institutions and Mobile Photo Payments™ is for organizations that bill consumers directly. Both allow a consumer to take a photo of a bill to extract data which is then used to pre-fill the fields required to accomplish certain tasks such as making a mobile payment, adding a new payee or paying monthly bills on a smartphone or tablet.
	Mobile Photo Balance Transfer™ allows a consumer to take a photo of a credit card statement to extract data which is then used to pre-fill the fields of a credit card balance transfer application. The consumer is then presented with a competitive credit card offer and can transfer the existing credit card balance to the new credit card. The Company’s mobile photo payment software solutions are available for iOS and Android operating systems.
	Developer Program
	In February 2014, the Company launched Mitek Developers. The program extends use of the Company’s mobile capture SDK and Mobile Imaging Platform™ to developers interested in creating new mobile applications that use camera-equipped smartphones and tablets to capture data from documents.
	Distribution Model
	The Company delivers its mobile capture software solutions on-premise as well as in the cloud and markets and sells these solutions through channel partners or directly to enterprise customers. The Company’s mobile capture software solutions are often embedded in mobile banking or enterprise applications developed by banks, insurance companies or their partners, and marketed under their own proprietary brands.
	Basis of Presentation
	The accompanying unaudited financial statements of the Company as of March 31, 2015 have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X and, accordingly, they do not include all information and footnote disclosures required by accounting principles generally accepted in the U.S. (“GAAP”). The Company believes the footnotes and other disclosures made in the financial statements are adequate for a fair presentation of the results of the interim periods presented. The financial statements include all adjustments (solely of a normal recurring nature) which are, in the opinion of management, necessary to make the information presented not misleading. You should read these financial statements and the accompanying notes in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2014, filed with the U.S. Securities and Exchange Commission (the “SEC”) on December 5, 2014 (the “Form 10-K”).
	Results for the three and six months ended March 31, 2015 are not necessarily indicative of results for any other interim period or for a full year.
	Reclassifications
	Certain prior period amounts have been reclassified to conform to the current period presentation. These reclassifications do not impact the reported net loss for such periods and do not have a material impact on the presentation of the overall financial statements.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses and the related disclosure of contingent assets and liabilities. On an ongoing basis, management reviews its estimates based upon currently available information. Actual future results could differ materially from those estimates. These estimates include, but are not limited to, assessing the collectability of accounts receivable, estimation of the value of stock-based compensation awards and income taxes.
	Net Income (Loss) Per Share
	The Company calculates net income (loss) per share in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 260, Earnings Per Share. Basic and diluted net income (loss) per share are based on the weighted-average number of common shares outstanding during the period, without giving effect to potentially dilutive securities. In a period with a net loss position, potentially dilutive securities, such as options, warrants and restricted stock units (“RSUs”), are not included in the calculation of diluted net loss because to do so would be antidilutive, and the number of shares used to calculate basic and diluted net loss is the same.
	For the three and six months ended March 31, 2015 and 2014, the following potentially dilutive common shares were excluded from the calculation of net income (loss) per share, as they would have been antidilutive:
		Three Months Ended						Six Months Ended
		March 31,						March 31,
		2015			2014			2015		2014
	Stock options		2,507,643			2,708,063			2,218,425		2,708,063
	Restricted stock units		399,780			1,155,472			435,461		1,155,472
	Warrants		-			6,667			-		6,667
	Total potentially dilutive common shares outstanding		2,907,423			3,870,202			2,653,886		3,870,202
	The calculation of basic and diluted net income (loss) per share is as follows:
		Three Months Ended						Six Months Ended
		March 31,						March 31,
		2015			2014			2015		2014
	Net income (loss)	$	507,650		$	(2,193,017	)	$	653,830	$	(3,661,317	)
	Weighted-average common shares outstanding:
	Basic		30,697,391			30,453,455			30,657,308		30,427,646
	Diluted		31,321,259			30,453,455			31,241,374		30,427,646
	Net income (loss) per share:
	Basic		0.02			(0.07	)		0.02		(0.12	)
	Diluted		0.02			(0.07	)		0.02		(0.12	)
	Revenue Recognition
	Revenue from sales of software licenses sold through direct and indirect channels is recognized upon shipment of the related product, if the requirements of FASB ASC Topic 985-605, Software Revenue Recognition (“ASC 985-605”) are met, including evidence of an arrangement, delivery, fixed or determinable fee, collectability and vendor specific objective evidence (“VSOE”) of the fair value of the undelivered element. If the requirements of ASC 985-605 are not met at the date of shipment, revenue is not recognized until such elements are known or resolved. Revenue from customer support services, or maintenance revenue, includes post-contract support and the rights to unspecified upgrades and enhancements. VSOE of fair value for customer support services is determined by reference to the price the customer pays for such element when sold separately; that is, the renewal rate offered to customers. Revenue derived from professional services primarily includes consulting, implementation, and training. Revenue from fixed fee service engagements is recognized after the services are performed using the completed performance method. Revenue from time and materials service engagements is generally recognized as the services are performed.
	In those instances when objective and reliable evidence of fair value exists for the undelivered items but not for the delivered items, the residual method is used to allocate the arrangement consideration. Under the residual method, the amount of arrangement consideration allocated to the delivered items equals the total arrangement consideration less the aggregate fair value of the undelivered items. Revenue from post-contract customer support is recognized ratably over the term of the contract. Certain customers have agreements that provide for usage fees above fixed minimums. Fixed minimum transaction fees are recognized as revenue ratably over the term of the arrangement. Usage fees above fixed minimums are recognized as revenue when such amounts are reasonably estimable and billable. Revenue from professional services is recognized when such services are delivered. When a software sales arrangement requires professional services related to significant production, modification or customization of software, or when a customer considers professional services essential to the functionality of the software product, revenue is recognized based on predetermined milestone objectives required to complete the project, as those milestone objectives are deemed to be substantive in relation to the work performed. Any expected losses on contracts in progress are recorded in the period in which the losses become probable and reasonably estimable.
	Accounts Receivable and Allowance for Doubtful Accounts
	Accounts receivable, net, is as follows:
		March 31,			September 30,
		2015			2014
	Accounts receivable	$	2,998,753		$	2,961,450
	Less: Allowance for doubtful accounts		(16,000	)		(6,100	)
	Accounts receivable, net	$	2,982,753		$	2,955,350
	Trade accounts receivable are recorded at the net invoice value and are not interest bearing. The Company considers receivables past due based on the contractual payment terms. Allowances for doubtful accounts are established based on various factors, including credit profiles of the Company’s customers, contractual terms and conditions, historical payments, and current economic trends. The Company reviews its allowances by assessing individual accounts receivable over a specific aging and amount. Accounts receivable are written off on a case-by-case basis, net of any amounts that may be collected.
	Capitalized Software Development Costs
	Costs incurred for the development of software that will be sold, leased or otherwise marketed are capitalized when technological feasibility has been established. Software development costs consist primarily of compensation of development personnel and related overhead incurred to develop new products and upgrade and enhance the Company’s current products, as well as fees paid to outside consultants. Capitalization of software development costs ceases and amortization of capitalized software development costs commences when the products are available for general release. For the three and six months ended March 31, 2015 and 2014, no software development costs were capitalized because the time period and costs incurred between technological feasibility and general release for all software product releases were not material.
	Fair Value of Equity Instruments
	The fair value of equity instruments involves significant estimates based on underlying assumptions made by management. The fair value for purchase rights under the Company’s equity plans is measured at the grant date using a Black-Scholes valuation model, which involves estimates of stock volatility, expected life of the instruments and other assumptions, and using the closing price of the Company’s common stock on the grant date for RSUs. The fair value of stock-based awards is recognized as an expense over the respective terms of the awards.
	Deferred Income Taxes
	Deferred income taxes reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the tax basis of such assets and liabilities. The Company maintains a valuation allowance against its deferred tax assets due to the uncertainty regarding the future realization of such assets, which is based on historical taxable income, projected future taxable income and the expected timing of the reversals of existing temporary differences. Until such time as the Company can demonstrate that it will no longer incur losses, or if the Company is unable to generate sufficient future taxable income, it could be required to maintain the valuation allowance against its deferred tax assets.
	Comprehensive Income (Loss)
	Comprehensive income (loss) consists of net income (loss) and unrealized gains and losses on available-for-sale securities. Included on the balance sheet at March 31, 2015 is an accumulated other comprehensive loss of $13,664, compared to an accumulated other comprehensive loss of $7,810 at September 30, 2014, related to the Company’s available-for-sale securities.
Recent Accounting Pronouncements
In May 2014, the FASB issued guidance codified in ASC 606, Revenue Recognition – Revenue from Contracts with Customers (“ASC 606”) which amends the guidance in former ASC 605, Revenue Recognition.  This accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2018.  The FASB has issued for public comment a proposed Accounting Standards Update, Revenue from Contracts with Customers (Topic 606):  Deferral of the Effective Date that would defer the effective date of its new revenue recognition standard by one year. The Company is currently evaluating the impact of the provisions of ASC 606.

	Total		$	18,348,998	$	1,472	$	(9,282	)	$	18,341,188
	The cost of securities sold is based on the specific identification method. Amortization of premiums, accretion of discounts, interest, dividend income and realized gains and losses are included in investment income.
	The Company determines the appropriate designation of investments at the time of purchase and reevaluates such designation as of each balance sheet date. All of the Company’s investments are designated as available-for-sale debt securities. As of March 31, 2015 and September 30, 2014, the Company’s short-term investments have maturity dates of less than one year from the balance sheet date and the Company’s long-term investments have maturity dates of greater than one year from the balance sheet date.
	Available-for-sale marketable securities are carried at fair value as determined by quoted market prices for identical or similar assets, with unrealized gains and losses, net of tax, and reported as a separate component of stockholders’ equity. Management reviews the fair value of the portfolio at least monthly, and evaluates individual securities with fair value below amortized cost at the balance sheet date. For debt securities, in order to determine whether impairment is other than temporary, management must conclude whether the Company intends to sell the impaired security and whether it is more likely than not that the Company will be required to sell the security before recovering its amortized cost basis. If management intends to sell an impaired debt security or it is more likely than not that the Company will be required to sell the security prior to recovering its amortized cost basis, an other-than-temporary impairment is deemed to have occurred. The amount of an other-than-temporary impairment on debt securities related to a credit loss, or securities that management intends to sell before recovery, is recognized in earnings. The amount of an other-than-temporary impairment on debt securities related to other factors is recorded consistent with changes in the fair value of all other available-for-sale securities as a component of stockholders’ equity in other comprehensive income. No other-than-temporary impairment charges were recognized in the three and six months ended March 31, 2015 and 2014.
	Fair Value Measurements and Disclosures
	FASB ASC Topic 820, Fair Value Measurements (“ASC 820”) defines fair value, establishes a framework for measuring fair value under GAAP and enhances disclosures about fair value measurements. Fair value is defined under ASC 820 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs. ASC 820 describes a fair value hierarchy based on the following three levels of inputs that may be used to measure fair value, of which the first two are considered observable and the last unobservable:
	·	Level 1—Quoted prices in active markets for identical assets or liabilities;
	·	Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as 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 market data for substantially the full term of the assets or liabilities; and
	·	Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	Based on the fair value hierarchy, all of the Company’s investments are classified as Level 2, as represented in the following table:

	Stock-Based Compensation Expense
	The following table summarizes stock-based compensation expense related to stock options and RSUs, which was allocated as follows:
		Three Months Ended					Six Months Ended
		March 31,					March 31,
		2015			2014		2015		2014
	Sales and marketing	$	191,962		$	234,167	$	367,080	$	435,690

	expenses
	No stock options were granted to employees during the six months ended March 31, 2014. The fair value calculations for stock-based compensation awards to employees for the six months ended March 31, 2015 were based on the following assumptions:
		Six Months Ended
		31-Mar-15
	Risk-free interest rate	1.29 – 1.66%
	Expected life (years)		5.25
	Expected volatility		98%
	Expected dividends	None
	The expected life of options granted is derived using assumed exercise rates based on historical exercise patterns and vesting terms, and represents the period of time that options granted are expected to be outstanding. Expected stock price volatility is based upon implied volatility and other factors, including historical volatility. After assessing all available information on either historical volatility, implied volatility, or both, the Company concluded that a combination of both historical and implied volatility provides the best estimate of expected volatility.
	As of March 31, 2015, the Company had $6,270,849 of unrecognized compensation expense related to outstanding stock options and RSUs expected to be recognized over a weighted-average period of approximately 2.8 years.
	2012 Incentive Plan
	In January 2012, the Company’s board of directors adopted the Mitek Systems, Inc. 2012 Incentive Plan (the “2012 Plan”), upon the recommendation of the compensation committee of the Company’s board of directors. On February 19, 2014, the Company’s stockholders approved an amendment to the 2012 Plan that increased the total number of shares of the Company’s common stock reserved for issuance thereunder from 2,000,000 shares to 4,000,000 shares plus that number of shares of the Company’s common stock that would otherwise return to the available pool of unissued shares reserved for awards under its 1999 Stock Option Plan, 2000 Stock Option Plan, 2002 Stock Option Plan, 2006 Stock Option Plan and 2010 Stock Option Plan (collectively, the “Prior Plans”).  As of March 31, 2015, (i) stock options to purchase 2,232,477 shares of the Company’s common stock and 541,091 RSUs were outstanding under the 2012 Plan, and 1,292,117 shares of the Company’s common stock were reserved for future grants under the 2012 Plan and (ii) stock options to purchase an aggregate of 1,478,244 shares of the Company’s common stock were outstanding under the Prior Plans.
	Director Restricted Stock Unit Plan
	In January 2011, the Company’s board of directors adopted the Mitek Systems, Inc. Director Restricted Stock Unit Plan, as amended and restated (the “Director Plan”), reserving up to 1,000,000 shares of the Company’s common stock  for the issuance of RSUs that may be granted to both employee and non-employee members of the Company’s board of directors. As of March 31, 2015, (i) 384,998 RSUs were outstanding under the Director Plan and (ii) 510,171 shares of the Company’s common stock were reserved for future grants under the Director Plan.

Income Tax Disclosure [Abstract]
Income Taxes	4. INCOME TAXES
	The Company’s deferred tax assets are primarily comprised of federal and state net operating loss carryforwards. Such federal and state net operating loss carryforwards begin to expire in the fiscal years ending September 30, 2018 and September 30, 2015, respectively.  The Company carries a deferred tax valuation allowance equal to 100% of the net deferred tax assets. In recording this allowance, management has considered a number of factors, particularly the Company’s recent history of sustained operating losses. Management has concluded that a valuation allowance is required for 100% of the net deferred tax assets as it is more likely than not that the deferred tax assets will not be realized.
	There can be no assurance that the Company will ever realize the benefit of any or all of the federal and state net operating loss carryforwards or the credit carryforwards, either due to ongoing operating losses or due to ownership changes, which may limit the usefulness of the net operating loss carryforwards. Due to the 100% valuation allowance on the net deferred tax assets, the Company does not anticipate that future changes in the Company’s unrecognized tax benefits will impact its effective tax rate.
	The Company’s policy is to classify interest and penalties related to income tax matters as income tax expense. The Company had no accrual for interest or penalties as of March 31, 2015 or March 31, 2014, and has not recognized interest and/or penalties in the statements of operations for the three and six months ended March 31, 2015 or March 31, 2014.

	Legal Matters
	Rothschild Mobile Imaging Innovations, Inc.
	On May 16, 2014, Rothschild Mobile Imaging Innovations, Inc. (“RMII”) filed a complaint against the Company in the U.S. District Court for the District of Delaware alleging that certain of the Company’s mobile imaging products infringe four RMII-owned patents related to mobile imaging technology. On June 1, 2014, RMII amended its complaint to add JPMorgan Chase & Co. and JPMorgan Chase Bank, N.A. (together, “Chase”), one of the Company’s customers, as a defendant in the lawsuit (as amended, the “Initial Lawsuit”). On September 8, 2014, RMII filed three additional complaints (the “Subsequent Lawsuits” and together with the Initial Lawsuit, the “RMII Lawsuits”) against the Company in the U.S. District Court for the District of Delaware. The Subsequent Lawsuits contain allegations substantially similar to the Initial Lawsuit regarding infringement by the Company’s mobile imaging products of the four RMII-owned patents related to mobile imaging technology, but name as co-defendants Citibank, N.A., Citigroup Inc., Wells Fargo & Company, Wells Fargo Bank, N.A., Bank of America Corporation and Bank of America, N.A., respectively (together with Chase, the “Bank Defendants”), each of whom offers the Company’s mobile imaging technology as part of its mobile banking applications. The trial has been scheduled for April 3, 2017.
	The Company has filed motions to dismiss RMII’s willful infringement claims against the Company in the Initial Lawsuit and motions to dismiss claims against the Company in the Subsequent Lawsuits. On November 10, 2014, the Company filed a motion to sever and stay the claims against Chase in the Initial Lawsuit pending resolution of RMII’s claims against the Company and to transfer the claims against the Company to the Southern District of California. On November 19, 2014, the Company filed joinders to the motion to stay with respect to the Subsequent Lawsuits. All motions are still pending before the Court.
	Based on the Company’s current understanding of the claims, the Company has agreed to accept the demands for indemnity and defense tendered by each of the Bank Defendants in connection with their respective RMII Lawsuits. The Company is currently controlling the defense of such claims and has taken actions to defend the RMII Lawsuits, as more fully described above. The Company believes that RMII’s claims are without merit and intends to vigorously defend against those claims. The Company does not believe that the results of the RMII Lawsuits will have a material adverse effect on its financial condition or results of operations.
	Other Legal Matters
	In addition to the foregoing, the Company is subject to various claims and legal proceedings arising in the ordinary course of its business. The Company accrues for such liabilities when it is both (i) probable that a loss has occurred and (ii) the amount of the loss can be reasonably estimated in accordance with ASC 450, Contingencies. While any legal proceeding has an element of uncertainty, the Company believes that the disposition of such matters, in the aggregate, will not have a material effect on the Company’s financial condition or results of operations.
	Facility Lease
	The Company’s principal executive offices, as well as its research and development facility, are located in approximately 22,523 square feet of office space in San Diego, California. The term of the lease for the Company’s offices continues through June 30, 2019. The annual base rent under the lease is approximately $471,000 per year and is subject to annual increases of approximately 3% per year. In connection with the lease, the Company received tenant improvement allowances totaling $675,690. These lease incentives are being amortized as a reduction of rent expense over the term of the lease. As of March 31, 2015, the unamortized balance of the lease incentives was $445,845, of which $104,905 has been included in other current liabilities and $340,940 has been included in other non-current liabilities. Under the terms of the lease, the Company issued a standby letter of credit to the landlord that allows for one or more draws of up to $210,000 over the term of the lease. The Company believes its existing properties are in good condition and are sufficient and suitable for the conduct of its business.

Risks And Uncertainties [Abstract]
Revenue and Vendor Concentrations	6. REVENUE AND VENDOR CONCENTRATIONS
	Revenue Concentration
	For the three months ended March 31, 2015, the Company derived revenue of $2,287,599 from two customers, with such customers accounting for 29% and 11%, respectively, of the Company’s total revenue.  For the three months ended March 31, 2014, the Company derived revenue of $1,644,145 from one customer accounting for 37% of the Company’s total revenue. For the six months ended March 31, 2015, the Company derived revenue of $4,385,305 from two customers, with such customers accounting for 29% and 11%, respectively, of the Company’s total revenue.  For the six months ended March 31, 2014, the Company derived revenue of $4,055,587 from two customers, with such customers accounting for 35% and 11%, respectively, of the Company’s total revenue. The corresponding accounts receivable balances of customers from which revenues were in excess of 10% of total revenue were $2,043,769 and $1,471,245, respectively, at March 31, 2015 and 2014.
	The Company’s revenue is derived primarily from the sale by the Company to channel partners, including systems integrators and resellers, and end-users of licenses to sell products covered by the Company’s patented technologies. These contractual arrangements do not obligate the Company’s channel partners to order, purchase or distribute any fixed or minimum quantities of the Company’s products. In most cases, the channel partners purchase the license from the Company after they receive an order from an end-user. The channel partners receive orders from various individual end-users; therefore, the sale of a license to a channel partner may represent sales to multiple end-users. End-users can purchase the Company’s products through more than one channel partner.
	Revenues can fluctuate based on the timing of license renewals by channel partners. When a channel partner purchases or renews a license, the Company receives a license fee in consideration for the grant of a license to sell the Company’s products and there are no future payment obligations related to such agreement; therefore, the license fee the Company receives with respect to a particular license renewal in one period does not have a correlation with revenue in future periods. During the last several quarters, sales of licenses to one or more channel partners have comprised a significant part of the Company’s revenue. This is attributable to the timing of renewals or purchases of licenses and does not represent a dependence on any single channel partner. The Company believes that it is not dependent upon any single channel partner, even those from which revenues were in excess of 10% of the Company’s total revenue in a specific reporting period, and that the loss or termination of the Company’s relationship with any such channel partner would not have a material adverse effect on the Company’s future operations because either we or another channel partner could sell our products to the end-user that had purchased from the channel partner we lost.
	International sales accounted for approximately 4% and 3% of the Company’s total revenue for the three and six months ended March 31, 2015, respectively. International sales accounted for approximately 6% and 7% of the Company’s total revenue for the three and six months ended March 31, 2014, respectively. The Company sells its products in U.S. currency only.
	Vendor Concentration
	The Company purchases its integrated software components from multiple third-party software providers at competitive prices. For the three and six months ended March 31, 2015 and 2014, the Company did not make purchases from any one vendor comprising 10% or more of the Company’s total purchases. The Company has entered into contractual relationships with some of its vendors; however, the Company does not believe it is substantially dependent upon nor exposed to any significant concentration risk related to purchases from any of its vendors, given the availability of alternative sources for its necessary integrated software components.

Nature of Operations	Nature of Operations
	Mitek Systems, Inc. (the “Company”) is engaged in the development, sale and service of its proprietary software solutions related to mobile capture and identity authentication.
	The Company applies its patented technology in image capture, correction and intelligent data extraction in the mobile financial and business services markets. The Company’s technology allows users to remotely deposit checks, pay bills, transfer credit card balances, open accounts and get insurance quotes by taking pictures of various documents with their camera-equipped smartphones and tablets instead of using the device keyboard. The Company’s products use advanced algorithms to correct image distortion, extract relevant data, route images to their desired location and process transactions through users’ financial institutions. As of March 31, 2015, the Company has been granted 21 patents and has an additional 21 patent applications pending.
	The Company’s products enable deposits, confirm identity and accelerate payments for mobile transactions.
	Deposit
	The Company’s Mobile Deposit® and Commercial Mobile Deposit Capture™ products are software that allows consumers and businesses to remotely deposit checks using their camera-equipped smartphone or tablet. As of March 31, 2015, 3,705 financial institutions have signed agreements to deploy Mobile Deposit® and 3,181 of these financial institutions have deployed Mobile Deposit® to their consumers, including all of the top ten, and  nearly all  of the top 50, U.S. retail banks, as ranked by SNL Financial for the fourth quarter of calendar year 2014. Commercial Mobile Deposit Capture™ utilizes the same technology as Mobile Deposit®, but has additional capabilities specifically designed to meet the needs of business users such as invoice capture.
	Identity
	The Company’s identity offerings feature Mobile Photo Account Opening™ which allows a consumer to take a photo of his or her driver’s license or other identity document to pre-fill mobile application forms on a mobile device. The Company’s identity offerings are currently in early deployment with large banks and insurance companies where they help consumers to open new financial accounts or get competitive rate quotes. Mobile Photo Account Opening™ can be used by bank personnel (both in-branch or at a community event) as well as by consumers on their mobile device (both native app or mobile web).
	Payment
	The Company’s mobile photo payment solutions enable mobile bill payment for financial institutions and organizations that bill consumers directly.
	Mobile Photo Bill Pay® is for financial institutions and Mobile Photo Payments™ is for organizations that bill consumers directly. Both allow a consumer to take a photo of a bill to extract data which is then used to pre-fill the fields required to accomplish certain tasks such as making a mobile payment, adding a new payee or paying monthly bills on a smartphone or tablet.
	Mobile Photo Balance Transfer™ allows a consumer to take a photo of a credit card statement to extract data which is then used to pre-fill the fields of a credit card balance transfer application. The consumer is then presented with a competitive credit card offer and can transfer the existing credit card balance to the new credit card. The Company’s mobile photo payment software solutions are available for iOS and Android operating systems.
	Developer Program
	In February 2014, the Company launched Mitek Developers. The program extends use of the Company’s mobile capture SDK and Mobile Imaging Platform™ to developers interested in creating new mobile applications that use camera-equipped smartphones and tablets to capture data from documents.
	Distribution Model
	The Company delivers its mobile capture software solutions on-premise as well as in the cloud and markets and sells these solutions through channel partners or directly to enterprise customers. The Company’s mobile capture software solutions are often embedded in mobile banking or enterprise applications developed by banks, insurance companies or their partners, and marketed under their own proprietary brands.
Basis of Presentation	Basis of Presentation
	The accompanying unaudited financial statements of the Company as of March 31, 2015 have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X and, accordingly, they do not include all information and footnote disclosures required by accounting principles generally accepted in the U.S. (“GAAP”). The Company believes the footnotes and other disclosures made in the financial statements are adequate for a fair presentation of the results of the interim periods presented. The financial statements include all adjustments (solely of a normal recurring nature) which are, in the opinion of management, necessary to make the information presented not misleading. You should read these financial statements and the accompanying notes in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2014, filed with the U.S. Securities and Exchange Commission (the “SEC”) on December 5, 2014 (the “Form 10-K”).
	Results for the three and six months ended March 31, 2015 are not necessarily indicative of results for any other interim period or for a full year.
Reclassifications	Reclassifications
	Certain prior period amounts have been reclassified to conform to the current period presentation. These reclassifications do not impact the reported net loss for such periods and do not have a material impact on the presentation of the overall financial statements.
Use of Estimates	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses and the related disclosure of contingent assets and liabilities. On an ongoing basis, management reviews its estimates based upon currently available information. Actual future results could differ materially from those estimates. These estimates include, but are not limited to, assessing the collectability of accounts receivable, estimation of the value of stock-based compensation awards and income taxes.
Net Income (Loss) Per Share	Net Income (Loss) Per Share
	The Company calculates net income (loss) per share in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 260, Earnings Per Share. Basic and diluted net income (loss) per share are based on the weighted-average number of common shares outstanding during the period, without giving effect to potentially dilutive securities. In a period with a net loss position, potentially dilutive securities, such as options, warrants and restricted stock units (“RSUs”), are not included in the calculation of diluted net loss because to do so would be antidilutive, and the number of shares used to calculate basic and diluted net loss is the same.
Revenue Recognition	Revenue Recognition
	Revenue from sales of software licenses sold through direct and indirect channels is recognized upon shipment of the related product, if the requirements of FASB ASC Topic 985-605, Software Revenue Recognition (“ASC 985-605”) are met, including evidence of an arrangement, delivery, fixed or determinable fee, collectability and vendor specific objective evidence (“VSOE”) of the fair value of the undelivered element. If the requirements of ASC 985-605 are not met at the date of shipment, revenue is not recognized until such elements are known or resolved. Revenue from customer support services, or maintenance revenue, includes post-contract support and the rights to unspecified upgrades and enhancements. VSOE of fair value for customer support services is determined by reference to the price the customer pays for such element when sold separately; that is, the renewal rate offered to customers. Revenue derived from professional services primarily includes consulting, implementation, and training. Revenue from fixed fee service engagements is recognized after the services are performed using the completed performance method. Revenue from time and materials service engagements is generally recognized as the services are performed.
	In those instances when objective and reliable evidence of fair value exists for the undelivered items but not for the delivered items, the residual method is used to allocate the arrangement consideration. Under the residual method, the amount of arrangement consideration allocated to the delivered items equals the total arrangement consideration less the aggregate fair value of the undelivered items. Revenue from post-contract customer support is recognized ratably over the term of the contract. Certain customers have agreements that provide for usage fees above fixed minimums. Fixed minimum transaction fees are recognized as revenue ratably over the term of the arrangement. Usage fees above fixed minimums are recognized as revenue when such amounts are reasonably estimable and billable. Revenue from professional services is recognized when such services are delivered. When a software sales arrangement requires professional services related to significant production, modification or customization of software, or when a customer considers professional services essential to the functionality of the software product, revenue is recognized based on predetermined milestone objectives required to complete the project, as those milestone objectives are deemed to be substantive in relation to the work performed. Any expected losses on contracts in progress are recorded in the period in which the losses become probable and reasonably estimable.
Capitalized Software Development Costs	Capitalized Software Development Costs
	Costs incurred for the development of software that will be sold, leased or otherwise marketed are capitalized when technological feasibility has been established. Software development costs consist primarily of compensation of development personnel and related overhead incurred to develop new products and upgrade and enhance the Company’s current products, as well as fees paid to outside consultants. Capitalization of software development costs ceases and amortization of capitalized software development costs commences when the products are available for general release. For the three and six months ended March 31, 2015 and 2014, no software development costs were capitalized because the time period and costs incurred between technological feasibility and general release for all software product releases were not material.
Fair Value of Equity Instruments	Fair Value of Equity Instruments
	The fair value of equity instruments involves significant estimates based on underlying assumptions made by management. The fair value for purchase rights under the Company’s equity plans is measured at the grant date using a Black-Scholes valuation model, which involves estimates of stock volatility, expected life of the instruments and other assumptions, and using the closing price of the Company’s common stock on the grant date for RSUs. The fair value of stock-based awards is recognized as an expense over the respective terms of the awards.
Deferred Income Taxes	Deferred Income Taxes
	Deferred income taxes reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the tax basis of such assets and liabilities. The Company maintains a valuation allowance against its deferred tax assets due to the uncertainty regarding the future realization of such assets, which is based on historical taxable income, projected future taxable income and the expected timing of the reversals of existing temporary differences. Until such time as the Company can demonstrate that it will no longer incur losses, or if the Company is unable to generate sufficient future taxable income, it could be required to maintain the valuation allowance against its deferred tax assets.
Comprehensive Income (Loss)	Comprehensive Income (Loss)
	Comprehensive income (loss) consists of net income (loss) and unrealized gains and losses on available-for-sale securities. Included on the balance sheet at March 31, 2015 is an accumulated other comprehensive loss of $13,664, compared to an accumulated other comprehensive loss of $7,810 at September 30, 2014, related to the Company’s available-for-sale securities.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In May 2014, the FASB issued guidance codified in ASC 606, Revenue Recognition – Revenue from Contracts with Customers (“ASC 606”) which amends the guidance in former ASC 605, Revenue Recognition.  This accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2018.  The FASB has issued for public comment a proposed Accounting Standards Update, Revenue from Contracts with Customers (Topic 606):  Deferral of the Effective Date that would defer the effective date of its new revenue recognition standard by one year. The Company is currently evaluating the impact of the provisions of ASC 606.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts
	Trade accounts receivable are recorded at the net invoice value and are not interest bearing. The Company considers receivables past due based on the contractual payment terms. Allowances for doubtful accounts are established based on various factors, including credit profiles of the Company’s customers, contractual terms and conditions, historical payments, and current economic trends. The Company reviews its allowances by assessing individual accounts receivable over a specific aging and amount. Accounts receivable are written off on a case-by-case basis, net of any amounts that may be collected.
