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 a mobile solutions provider engaged in the development, sale and service of its proprietary software solutions.
	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 November 21, 2013, the Company’s has been granted 18 patents and it has an additional 21 patent applications pending.
	The Company’s Mobile Deposit® product is software that allows users to remotely deposit a check using their camera-equipped smartphone or tablet. As of September 30, 2013, 1,420 financial institutions have signed agreements to deploy Mobile Deposit®, and 805 of these financial institutions have deployed Mobile Deposit® to their customers, including all of the top ten U.S. retail banks and more than two-thirds of the top 50 U.S. retail banks and payment processing companies, as ranked by SNL Financial for the second quarter of calendar 2013. Other mobile imaging software solutions offered by the Company include Mobile Photo Bill Pay®, a mobile bill payment product that allows users to pay their bills using their camera-equipped smartphone or tablet, Mobile Balance Transfer™, a product that allows credit card issuers to provide an offer to users and transfer an existing credit card balance by capturing an image of the user’s current credit card statement, Mobile Photo Account Opening™, a product that enables users to open a checking, savings or credit card account by capturing an image of the front and back of their driver’s license with their camera-equipped smartphone or tablet, and Mobile Photo Quoting™, a product that enables users to receive insurance quotes by using their camera-equipped smartphone or tablet to take a picture of their driver’s license and insurance card. The Company’s mobile imaging software solutions can be accessed by smartphones and tablets using iOS and Android operating systems.
	The Company markets and sells its mobile imaging software solutions through channel partners or directly to enterprise customers that typically purchase licenses based on of the number of transactions or subscribers that use our mobile software. The Company’s mobile imaging software solutions are often embedded in other mobile banking or enterprise applications developed by banks, insurance companies or their partners, and marketed under their own proprietary brands.
	Basis of Presentation
	The financial statements are prepared under the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 105-10, Generally Accepted Accounting Principles, in accordance with accounting principles generally accepted in the U.S. (“GAAP”).
	Reclassifications
	Certain prior period amounts have been reclassified to conform to the current period presentation. These reclassifications do not impact the reported net loss 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, expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, management reviews its estimates based upon currently available information. Actual results could differ materially from those estimates.
	Net Loss Per Share
	The Company calculates net income (loss) per share in accordance with FASB ASC Topic 260, Earnings Per Share. Basic net income (loss) per share is based on the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share also gives effect to all potentially dilutive securities outstanding during the period, such as options, warrants and restricted stock units (“RSUs”), if dilutive. In a period with a net loss position, potentially dilutive securities are not included in the computation 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.
	At September 30, 2013, 2012 and 2011, the following potentially dilutive common shares were excluded from the net loss per share calculation, as they would have been antidilutive:
		2013			2012			2011
	Stock options		2,824,964			3,512,286			4,553,904
	Warrants		6,667			6,667			132,189
	Restricted stock units		692,504			515,834			300,000
	Total potentially dilutive common shares outstanding		3,524,135			4,034,787			4,986,093
	The computation of basic and diluted net loss per share for the fiscal years ended September 30, 2013, 2012 and 2011 is as follows:
		2013			2012			2011
	Net loss	$	(7,275,706	)	$	(7,839,996	)	$	(125,057	)
	Weighted-average common shares and share equivalents outstanding—basic		27,492,670			25,124,179			21,506,508
	Effect of dilutive stock options		—			—			—
	Weighted-average common shares and share equivalents outstanding—diluted		27,492,670			25,124,179			21,506,508
	Net loss per share:
	Basic	$	(0.26	)	$	(0.31	)	$	(0.01	)
	Diluted	$	(0.26	)	$	(0.31	)	$	(0.01	)
	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. 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.
	Cash and Cash Equivalents
	Cash and cash equivalents are defined as highly liquid financial instruments with original maturities of three months or less. A substantial portion of the Company’s cash is deposited with one financial institution. The Company monitors the financial condition of this financial institution and does not believe that funds on deposit are subject to a significant degree of risk.
	Investments
	Investments consist of corporate notes and bonds, and commercial paper. The Company classifies investments as available-for-sale at the time of purchase and reevaluates such classification as of each balance sheet date. All investments are recorded at estimated fair value. Unrealized gains and losses for available-for-sale securities are included in accumulated other comprehensive income, a component of stockholders’ equity. The Company evaluates its investments to assess whether those with unrealized loss positions are other than temporarily impaired. Impairments are considered to be other-than-temporary if they are related to deterioration in credit risk or if it is likely that the Company will sell the securities before the recovery of its cost basis. Realized gains and losses and declines in value judged to be other-than-temporary are determined based on the specific identification method and are reported in other income (expense), net in the Statements of Operations. No other-than-temporary impairment charges were recognized in the fiscal years ended September 30, 2013, 2012 and 2011.
	All investments whose maturity or sale is expected within one year are classified as “current” on the balance sheet. All other securities are classified as “long-term” on the balance sheet.
	Fair Value Measurements
	The carrying amounts of cash equivalents, investments, accounts receivable, accounts payable and other accrued liabilities are considered representative of their respective fair values because of the short-term nature of those instruments.
	Accounts Receivable and Allowance for Doubtful Accounts
	Accounts receivable, net, is as follows (in thousands):
		September 30,			September 30,
		2013			2012
	Accounts receivable	$	1,506,627		$	1,115,084
	Less: Allowance for doubtful accounts		(12,000	)		(17,773	)
	Accounts receivable, net	$	1,494,627		$	1,097,311
	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. The Company had no write-offs of the allowance for doubtful accounts for the years ended September 30, 2013 and 2012, respectively.
	Deferred Maintenance Fees
	Deferred maintenance fees consist of capitalized costs associated with software maintenance fees paid to vendors who supply licenses and maintenance for software embedded in the Company’s products that it sells to customers. These software maintenance fees, which are included in other current assets on the balance sheet, are typically billed annually to the Company and are amortized to cost of revenue-maintenance and professional services in the Statements of Operations over the maintenance period, which is typically one year.
	Property and Equipment
	Property and equipment are carried at cost. The following is a summary of property and equipment as of September 30, 2013 and 2012:
		2013			2012
	Property and equipment—at cost:
	Equipment	$	1,054,868		$	684,552
	Furniture and fixtures		227,189			130,559
	Leasehold improvements		975,838			65,227
			2,257,895			880,338
	Less: accumulated depreciation and amortization		(628,231	)		(460,223	)
	Construction in progress		—			70,964
	Total property and equipment, net	$	1,629,664		$	491,079
	Depreciation and amortization of property and equipment are provided using the straight-line method over estimated useful lives ranging from three to five years. Leasehold improvements are amortized over the lease term. Depreciation and amortization of property and equipment totaled $323,383, $140,146 and $42,133 for the fiscal years ended September 30, 2013, 2012 and 2011, respectively. Included in property and equipment as of September 30, 2013 and 2012 in the table above is equipment of $95,388 purchased under a capital lease. There were no fixed assets acquired under capital leases at September 30, 2011. Depreciation expense related to the equipment purchased under the capital lease was $19,078 and $17,488 in the fiscal years ended September 30, 2013 and 2012, respectively, and accumulated depreciation was $36,566 and $17,488 at September 30, 2013 and 2012, respectively. The Company recorded no depreciation expense related to capital leases in the fiscal year ended September 30, 2011, nor was there any related accumulated depreciation at September 30, 2011. Expenditures for repairs and maintenance are charged to operations. Total repairs and maintenance expenses were $97,532, $57,815 and $43,115 for the fiscal years ended September 30, 2013, 2012 and 2011, respectively.
	Long-Lived Assets
	The Company evaluates the carrying value of long-lived assets, including license agreements and other intangible assets, when events and circumstances indicate that these assets may be impaired or in order to determine whether any revision to the related amortization periods should be made. This evaluation is based on management’s projections of the undiscounted future cash flows associated with each product or asset. If management’s evaluation indicates that the carrying values of these intangible assets were impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. The Company did not record any impairment for the fiscal years ended September 30, 2013, 2012 and 2011.
	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 fiscal years ended September 30, 2013 and 2012, no software development costs were capitalized because the time period and cost incurred between technological feasibility and general release for all software product releases were not material.
The Company evaluates its capitalized software development costs at each balance sheet date to determine if the unamortized balance related to any given product exceeds the estimated net realizable value of that product. Any such excess is written off through accelerated amortization in the quarter in which it is identified. Determining net realizable value, as defined by FASB ASC Topic 985-20, Accounting for the Costs of Software to Be Sold, Leased or Otherwise Marketed, requires making estimates and judgments in quantifying the appropriate amount to write off, if any. Actual amounts realized from the software products could differ from those estimates. Also, any future changes to the Company’s product portfolio could result in significant increases to its cost of license revenue as a result of the write-off of capitalized software development costs.
The Company recorded no amortization of software development costs for the fiscal year ended September 30, 2013. The Company recorded amortization of software development costs of $91,438 and $137,157 for the fiscal years ended September 30, 2012 and 2011, respectively. The Company records amortization of software development costs as cost of revenue-software in the Statements of Operations.
Deferred Revenue
Deferred revenues represent advance payments or billings for software licenses, professional services and maintenance billed in advance of the time we recognize the related revenues. Deferred maintenance revenue represents customer billings, paid up front, generally annually at the beginning of each maintenance period, with revenue recognized ratably over such period. For certain other licensing arrangements, revenue attributable to undelivered elements, including post-contract customer support which typically includes telephone support and the right to receive unspecified upgrades and enhancements of software on a when-and-if-available basis, is based upon the sales price of those elements when sold separately and is recognized ratably on a straight-line basis over the term of the arrangement.
Guarantees
In the ordinary course of business, the Company is not subject to potential obligations under guarantees that fall within the scope of FASB ASC Topic 460, Guarantees (“ASC 460”), except for standard indemnification and warranty provisions that are contained within many of the Company’s customer license and service agreements and certain supplier agreements, and give rise only to the disclosure requirements prescribed by ASC 460. Indemnification and warranty provisions contained within the Company’s customer license and service agreements and certain supplier agreements are generally consistent with those prevalent in the Company’s industry. The Company has not historically incurred significant obligations under customer indemnification or warranty provisions and does not expect to incur significant obligations in the future. Accordingly, the Company does not maintain accruals for potential customer indemnification or warranty-related obligations.
Income Taxes
The Company accounts for income taxes in accordance with FASB ASC Topic 740, Income Taxes (“ASC 740”). Deferred tax assets and liabilities arise from temporary differences between the tax bases of assets and liabilities and their reported amounts in the financial statements that will result in taxable or deductible amounts in future years.
Management evaluates the available evidence about future taxable income and other possible sources of realization of deferred tax assets. The valuation allowance reduces deferred tax assets to an amount that represents management’s best estimate of the amount of such deferred tax assets that more likely than not will be realized. See Note 5 for additional details.
The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax positions will be sustained on examination by the tax authorities, based on the technical merits of the position. The tax benefit is measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company recognizes interest and penalties related to income tax matters in income tax expense. See Note 5 for additional details.
Stock-Based Compensation
The Company records stock-based compensation in accordance with FASB ASC Topic 718, Compensation-Stock Compensation (“ASC 718”). The Company estimates the fair value of stock options using the Black-Scholes option pricing model. The fair value of stock options granted is recognized as an expense over the requisite service period. Stock-based compensation expense for all share-based payment awards is recognized using the straight-line single-option method.
The Black-Scholes option pricing model requires subjective assumptions, including future stock price volatility and expected time to exercise, which greatly affect the calculated values. The expected term of options granted is derived from historical data on employee exercises and post-vesting employment termination behavior. The risk-free rate selected to value any particular grant is based on the U.S. Treasury rate that corresponds to the expected life of the grant effective as of the date of the grant. The expected volatility is based on the historical volatility of the Company’s stock price. These factors could change in the future, affecting the determination of stock-based compensation expense in future periods.
Advertising Expense
Advertising costs are expensed as incurred and totaled $123,905, $72,053 and $76,026 during the fiscal years ended September 30, 2013, 2012 and 2011, respectively.
Research and Development
Research and development costs are expensed in the period incurred.
Leases
Leases are reviewed and classified as capital or operating at their inception. For leases that contain rent escalations, the Company records the total rent payable on a straight-line basis over the term of the lease. The difference between rent payments and straight-line rent expense is recorded as deferred rent.
Segment Reporting
FASB ASC Topic 280, Segment Reporting, requires the use of a management approach in identifying segments of an enterprise. During the fiscal year ended September 30, 2013, management determined that the Company has only one operating segment: the development, sale and service of our proprietary software solutions related to mobile imaging.
Comprehensive Loss
Comprehensive loss consists of net loss and unrealized gains and losses on available-for-sale securities. The following table summarizes the components of comprehensive loss for the fiscal years ended September 30, 2013, 2012 and 2011:
	2013			2012			2011
Net loss	$	(7,275,706	)	$	(7,839,996	)	$	(125,057	)
Other comprehensive loss:

Total comprehensive loss	$	(7,273,252	)	$	(7,830,757	)	$	(134,912	)
Included on the balance sheet at September 30, 2013 is an accumulated other comprehensive gain of $1,838, compared to an accumulated other comprehensive loss $616 at September 30, 2012, related to the Company’s available-for-sale-securities.

	2	INVESTMENTS
	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 September 30, 2013 and 2012, the Company’s short-term investments have maturity dates of greater than 90 days and less than one year from the balance sheet date. 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 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 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 fiscal years ended September 30, 2013, 2012 and 2011.
	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 following table summarizes investments by security type as of September 30, 2013 and 2012:

	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 three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which consists of the following:
		•		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 were classified as Level 2 at September 30, 2013 and 2012, as represented in the following table:

	3	DEBT
	Convertible Debt
	In December 2009, the Company entered into a securities purchase agreement with accredited investors pursuant to which the Company agreed to issue the following securities in exchange for aggregate consideration of $1,012,500: (i) 5% senior secured convertible debentures in the principal amount of approximately $1,000,000, and (ii) warrants to purchase an aggregate of 337,501 shares of the Company’s common stock with an exercise price of $0.91 per share. Each investor received a warrant to purchase that number of shares of the Company’s common stock that equals 25% of the quotient obtained by dividing such investor’s aggregate subscription amount by $0.75. The transaction resulted in proceeds to the Company of $922,223, net of transaction costs and expenses.
	In December 2010, the Company converted the then-outstanding balance of the debentures of $1,063,926, including accrued interest of $51,426, into 1,418,573 shares of the Company’s common stock at a conversion price of $0.75 per share. In addition, the Company recognized as interest expense the remaining unamortized discount of $319,836 related to the beneficial conversion feature at the time of conversion in accordance with FASB ASC Topic 470-20, Debt with Conversion and Other Options.
	Prior to the conversion, interest was payable in cash or stock at the rate of 5% per annum on each conversion date (as to the principal amount being converted), on each early redemption date (as to the principal amount being redeemed) and on the maturity date. The principal amount of the debentures, if not paid earlier, was due and payable on December 10, 2011. The Company had the right to redeem all or a portion of the debentures before maturity by payment in cash of the outstanding principal amount plus accrued and unpaid interest on the principal amount being redeemed. The Company agreed to honor any notices of conversion that it received from the holder before the date the Company paid off the debentures. The debentures were convertible into shares of the Company’s common stock at any time at the discretion of the holder at a conversion price of $0.75 per share, subject to adjustment for stock splits, stock dividends and the like. The Company had the right to force conversion of the debentures if (i) the closing price of its common stock exceeded 200% of the then-effective conversion price for 20 trading days out of a consecutive 30 trading-day period or (ii) the average daily trading volume for its common stock exceeded 100,000 shares per trading day for 20 trading days out of a consecutive 30 trading-day period and the closing price of its common stock exceeded 100% of the then-effective conversion price for 20 trading days out of a consecutive 30 trading-day period. The debentures imposed certain covenants on the Company including restrictions against paying cash dividends or distributions on shares of its outstanding common stock. The debentures were secured by all of the Company’s assets under the terms of a security agreement it entered into with the investors dated December 10, 2009.
	In evaluating the accounting for the convertible debentures, the Company considered whether the conversion option related to the convertible debentures required bifurcation and separate accounting as a liability at fair value. Because the conversion option entitled the holder to convert to a fixed number of shares at a fixed price, the Company was not required to bifurcate the conversion option and the related debt host. Similarly, the warrant contract entitled the holder to convert to a fixed number of shares at a fixed price and was therefore recorded in stockholders’ equity.
	Of the gross proceeds, $786,432 was allocated to the debentures and $226,068 to the warrants. The value of the warrants was estimated using a Black-Scholes option pricing model. The amount allocated to the warrants was recorded as a discount on the debentures and was being amortized to interest expense in the accompanying Statements of Operations over the term of the debentures. In addition, based on the conversion price of $0.75 and relative value of the debentures, a beneficial conversion feature of $401,568 was recorded as an additional discount on the debentures and was being amortized to interest expense in the accompanying Statements of Operations over the term of the debentures. The remaining unrecognized interest expense was recorded at the time of conversion.
	The fair value of the vested warrants was estimated on the grant date using the Black-Scholes option pricing model with the following assumptions:
	Risk-free interest rate		2.19	%
	Expected term (in years)		5
	Stock price volatility		207	%
	Expected dividend yield		0	%
	Credit Facility
	In January 2011, the Company entered into a loan and security agreement with its primary operating bank (the “Loan Agreement”). The Loan Agreement permitted the Company to borrow, repay and re-borrow up to $400,000 from time to time until January 31, 2013, subject to the terms and conditions of the Loan Agreement. The Loan Agreement expired on January 31, 2013, at which time there were no borrowings outstanding.

	Common Stock
	In October 2010, the Company sold 500,000 shares of common stock at $1.50 per share to accredited investors in a private placement, resulting in net proceeds of $750,000.
	In December 2010, the Company issued 1,418,573 shares of common stock upon the conversion of outstanding convertible debentures as discussed in greater detail in Note 3.
	In May 2011, the Company entered into a securities purchase agreement with certain accredited investors pursuant to which the Company sold to the investors an aggregate of 2,857,143 shares of the Company’s common stock at a purchase price of $5.25 per share for aggregate gross proceeds of $15,000,000. The Company paid cash compensation of approximately $1,050,000 in placement agent fees and reimbursed $25,000 of placement agent out-of-pocket expenses incurred in connection with the financing. In addition, the Company incurred legal fees of approximately $80,000 in connection with the private placement, resulting in net proceeds of approximately $13,845,000.
	In June, 2013, the Company sold 2,857,142 shares of its common stock at a price of $5.25 per share in an underwritten public offering (the “Offering”) and received $13,877,447 in net proceeds, after deducting underwriting discounts and commissions and other offering expenses of $1,122,549. Under the terms of the underwriting agreement for the Offering, the Company granted the underwriter a 30-day option to purchase an additional 428,571 shares of its common stock to cover overallotments. The underwriter exercised its overallotment option during June 2013 and the closing of the sale of shares of the Company’s common stock pursuant to such option occurred during July 2013, resulting in $2,127,350 in additional net proceeds to the Company.
	Warrants
	Historically, the Company has granted warrants to purchase its common stock to service providers and investors. As of September 30, 2013, there were warrants to purchase 6,667 shares of the Company’s common stock outstanding with an exercise price of $0.91 per share, subject to adjustment for stock splits, stock dividends and the like. These warrants expire in December 2014.
	In connection with the issuance of shares of common stock to John H. Harland Company (“JHH Co.”) in February and May 2005, the Company issued to JHH Co. warrants to purchase 321,428 shares of the Company’s common stock at an exercise price of $0.70 per share, subject to adjustment for stock splits, stock dividends and the like. In June 2011, JHH Co. exercised the warrants, which were due to expire between February and May 2012. The warrants were exercised under the cashless exercise method, resulting in the issuance of 288,582 shares of common stock to the warrant holder and the cancellation of the remaining 32,846 shares in consideration of the issuance.
	In connection with issuance of convertible debentures in December 2009, the Company issued warrants to purchase an aggregate of 337,501 shares of the Company’s common stock with an exercise price of $0.91 per share, as discussed in greater detail in Note 3. Of such warrants, warrants to purchase 330,834 shares of the Company’s common stock have been exercised and warrants to purchase 6,667 shares of common stock remain outstanding as of September 30, 2013. These warrants expire in December 2014.
	The following table summarizes warrant activity in the fiscal years ended September 30, 2013, 2012 and 2011:

	Stock-based Compensation
	The Company applies the fair value recognition provisions of ASC 718.
	The fair value of stock options granted to employees and directors is calculated using the Black-Scholes option pricing model. The Black-Scholes option pricing model requires subjective assumptions, including future stock price volatility and expected time to exercise, which greatly affect the calculated values. The expected term of options granted is derived from historical data on employee exercises and post-vesting employment termination behavior. The risk-free rate selected to value any particular grant is based on the U.S. Treasury rate that corresponds to the expected life of the grant effective as of the date of the grant. The expected volatility is based on the historical volatility of the Company’s stock price. These factors could change in the future, affecting the determination of stock-based compensation expense in future periods.
	The value of stock-based compensation is based on the single option valuation approach under ASC 718. It is assumed no dividends will be declared. The estimated fair value of stock-based compensation awards is amortized using the straight-line method over the vesting period of the option.
	ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The estimated average forfeiture rate for the fiscal year ended September 30, 2013 of 15.3% for all stock option grants was based on historical forfeiture experience.
	ASC 718 requires the cash flows from tax benefits resulting from tax deductions in excess of the compensation cost recognized for options to be classified as financing cash flows. Due to the Company’s valuation allowance from losses in the previous years, there were no such tax benefits during the fiscal years ended September 30, 2013, 2012 and 2011. Prior to the adoption of ASC 718, any tax benefits received by the Company related to stock option exercises would have been reported as operating cash flows.
	The fair value calculations for stock-based compensation awards to employees for the fiscal years ended September 30, 2013, 2012 and 2011 were based on the following assumptions:
			2013		2012	2011
	Risk-free interest rate		0.18% - 1.20%		0.35% - 1.06%	0.26% - 2.26%
	Expected life (years)		5.3		5	5.5
	Expected volatility		175%		110%	193%
	Expected dividends		None		None	None
	The following table summarizes stock-based compensation expense related to stock options and RSUs under ASC 718 for the fiscal years ended September 30, 2013, 2012 and 2011, which were allocated as follows:

The total intrinsic value of options exercised during the fiscal years ended September 30, 2013, 2012 and 2011 was $3,832,374, $14,215,750 and $4,731,689, respectively. The per-share weighted average fair value of options granted during the fiscal years ended September 30, 2013, 2012 and 2011 was $3.57, $5.97 and $3.54, respectively.
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 board of directors. The total number of shares of the Company’s common stock reserved for issuance under the 2012 Plan is 2,000,000 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 the Company’s 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”). There were no awards granted under the Prior Plans after the approval of the 2012 Plan by the Company’s stockholders on February 22, 2012. Stock options granted under the Prior Plans that were outstanding at such date remain in effect until such options are exercised or expire.
The 2012 Plan authorizes the grant of stock options, stock appreciation rights, restricted stock, RSUs and cash awards. Stock options granted under the 2012 Plan may be either options intended to constitute incentive stock options or nonqualified stock options, in each case as determined by the compensation committee of the board of directors in accordance with the terms of the 2012 Plan. As of September 30, 2013, stock options to purchase 1,214,397 shares of the Company’s common stock and 217,504 RSUs were outstanding under the 2012 Plan, and 776,308 shares of the Company’s common stock were reserved for future grants.
The following table summarizes the number of stock options outstanding under the Prior Plans as of September 30, 2013:
2000 Stock Option Plan			215,412
2002 Stock Option Plan			226,100
2006 Stock Option Plan			49,000
2010 Stock Option Plan			1,120,055
Total stock options outstanding under the Prior Plans			1,610,567
In May 2003, the Chief Executive Officer of the Company was granted an option to purchase up to 400,000 shares of the Company’s common stock in connection with his appointment as President and Chief Executive Officer. This grant was made without shareholder approval as an inducement award pursuant to Rule 5635(c)(4) of the NASDAQ Listing Rules. The Company filed a registration statement on Form S-8 with the Securities and Exchange Commission registering the shares subject to the grant on December 15, 2011.
Restricted Stock Units
In January 2011, the Company’s board of directors adopted, subject to stockholder approval, 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 to both employee and non-employee members of the board of directors of the Company. On February 23, 2011, the Director Plan was approved by the Company’s stockholders at its annual meeting.
In addition, the Company has awarded RSUs to certain of its employees under the 2012 Plan. The RSUs vest in equal annual installments over four years.
The following table summarizes RSU activity in the fiscal years ended September 30, 2013, 2012 and 2011:
		Number of			Weighted-average

The cost of a RSU is determined using the fair value of the Company’s common stock on the award date, and the compensation expense is recognized ratably over the vesting period. The Company recognized $768,839, $529,072 and $179,343 in stock-based compensation expense related to outstanding RSUs in the fiscal years ended September 30, 2013, 2012 and 2011, respectively. As of September 30, 2013, the Company had approximately $2,274,490 of unrecognized compensation expense related to outstanding RSUs expected to be recognized over a weighted-average period of approximately 3.1 years.

	Valuation allowance for net deferred tax assets			(11,313,377	)		(9,344,389	)
	Total		$	—		$	—
	The Company has provided a valuation allowance against deferred tax assets recorded as of September 30, 2013 and 2012 due to uncertainties regarding the realization of such assets.
	The net change in the total valuation allowance for the fiscal years ended September 30, 2013 and 2012 was an increase of $1,968,988 and $2,247,615, respectively. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during periods in which those temporary differences become deductible. The Company considers projected future taxable income and planning strategies in making this assessment. Based on the level of historical operating results and projections for future taxable income, the Company has determined that it is more likely than not that the deferred tax assets will not be realized. Accordingly, the Company has recorded a valuation allowance to reduce deferred tax assets to zero. There can be no assurance that the Company will ever be able to realize the benefit of some or all of the federal and state loss carryforwards or the credit carryforwards, either due to ongoing operating losses or due to ownership changes, which limit the usefulness of the loss carryforwards.
	As of September 30, 2013, the Company has available net operating loss carryforwards of $45,392,347 for federal income tax purposes, which will start to expire in 2018. The net operating loss carryforwards for state purposes are $35,164,486 and will begin to expire in 2013. Included in these amounts are federal and state net operating losses of $17,654,877 attributable to stock option deductions of which the tax benefit will be credited to equity when realized. As of September 30, 2013, the Company has available federal research and development credit carryforwards of $29,306 and alternative minimum tax credit carryforwards of $66,320. The research and development credits will start to expire in 2023. As of September 30, 2013, the Company has available state research and development credit carryforwards and manufacturers’ investment credit carryforwards of $21,963 and $8,346, respectively. The state research and development credits have no expiration date and the state manufacturers’ investment credits started to expire in the current year.
	The Company’s ability to use its net operating loss and research and development credit carryforwards may be substantially limited due to ownership change limitations that may have occurred or that could occur in the future, as required by Section 382 of the Internal Revenue Code of 1986, as amended (“Section 382”), as well as similar state provisions. The Company has not completed a study to assess whether an ownership change has occurred or whether there have been multiple ownership changes since the Company became a “loss corporation” as defined in Section 382. Due to the existence of the valuation allowance, it is not expected that any possible limitation will have an impact on the results of operations or financial position of the Company.
	The difference between the income tax provision (benefit) and income taxes computed using the U.S. federal income tax rate was as follows for the years ended September 30, 2013, 2012 and 2011:
			2013			2012			2011
	Amount computed using statutory rate		$	(2,473,374	)	$	(2,666,961	)	$	(42,519	)

	Income tax provision (benefit)		$	1,076		$	(4,008	)	$	2,492
	The Company files income tax returns in the U.S. federal jurisdiction and various state jurisdictions. Because the Company is carrying forward federal and state net operating losses from 1997 and 2002, respectively, the Company is subject to U.S. federal and state income tax examinations by tax authorities for all years since 1997 and 2002, as the case may be. The Company does not have any uncertain tax positions. As of September 30, 2013, no accrued interest or penalties are recorded in the financial statements.

	Legal Matters
	USAA
	On March 29, 2012, United Services Automobile Association (“USAA”) filed a complaint in the U.S. District Court for the Western District of Texas San Antonio Division against the Company seeking, among other things, a declaratory judgment that USAA does not infringe certain of the Company’s patents relating to Mobile Deposit®, and that such patents are not enforceable against USAA. In addition, USAA alleges that it disclosed confidential information to the Company and that the Company used such information in its patents and Mobile Deposit® product in an unspecified manner. USAA seeks damages and injunctive relief. USAA subsequently amended its pleadings to assert a claim for false advertising and reverse palming off under the Lanham Act, and to seek reimbursement under the parties’ license agreement.
	On April 12, 2012, the Company filed a lawsuit against USAA in the U.S. District Court for the District of Delaware, alleging that USAA infringes five of the Company’s patents relating to image capture on mobile devices, breached the parties’ license agreement by using the Company’s products beyond the scope of the agreed-upon license terms and breached the parties’ license agreement by disclosing confidential pricing and other confidential information for the Company’s legacy product installation in the lawsuit USAA filed in Texas.
	The courts consolidated the foregoing cases in the U.S. District Court for the Western District of Texas, and on November 19, 2012, the Company answered USAA’s various claims and counterclaims, moved to dismiss USAA’s Lanham Act cause of action and filed a counterclaim against USAA for violation of the Lanham Act. On February 15, 2013, the court granted the Company’s motion and dismissed USAA’s Lanham Act claim.
	The Company believes USAA’s claims are without merit and intends to vigorously defend against those claims and pursue its claims against USAA. The Company does not believe that the results of USAA’s claims will have a material adverse effect on its financial condition or results of operations.
	Top Image Systems Ltd.
	On September 26, 2012, the Company filed a lawsuit against Israeli-based Top Image Systems Ltd. and TIS America Inc. (collectively, “TISA”) in the U.S. District Court for the District of Delaware, alleging that TISA infringes five of the Company’s patents relating to image capture on mobile devices. The Company is seeking damages against TISA and injunctive relief to prevent them from selling their mobile imaging products.
	On January 7, 2013, TISA answered the Company’s complaint by denying the allegations and raising several affirmative defenses. On January 11, 2013, the Company amended its complaint to add its sixth patent, which had recently been issued and also relates to image capture on mobile devices. On January 28, 2013, TISA responded to the Company’s amended complaint by again denying the allegations and raising the same affirmative defenses that they raised in their answer to the Company’s initial complaint.
	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. 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.
	Employee 401(k) Plan
	The Company has a 401(k) plan that allows participating employees to contribute a percentage of their salary, subject to Internal Revenue Service annual limits. The Company’s board of directors may, at its sole discretion, approve matching contributions by the Company. During the fiscal years ended September 30, 2013, 2012 and 2011, the Company’s board of directors did not approve any Company matching contributions to the plan.
	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 September 30, 2013, the unamortized balance of the lease incentives was $603,202, of which $104,905 has been included in other current liabilities and $498,297 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.
	Future annual minimum rental payments payable under the lease are as follows:
	Years ending September 30:
	2014		$	481,535
	2015			495,981
	2016			510,861

	2018			541,972
	Thereafter			416,959
	Total		$	2,973,495
	Rent expense for the Company’s operating lease for its facility for the years ended September 30, 2013, 2012 and 2011 totaled $379,529, $335,946 and $288,041, respectively.

	Revenue Concentration
	For the fiscal year ended September 30, 2013, the Company derived revenue of $3,607,417, or 24% of the Company’s total revenue, from one customer, compared to revenue of $3,787,730 from three customers, with such customers accounting for 15%, 15% and 12%, respectively, of the Company’s total revenue for the fiscal year ended September 30, 2012. For the fiscal year ended September 30, 2011, the Company derived revenue of $3,384,788 from two customers, with such customers accounting for 22% 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 $588,475, $675,074 and $2,235,500 at September 30, 2013, 2012 and 2011, respectively.
	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. 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 few years, 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 the Company or another channel partner could sell the Company’s products to the end-user that purchased from the channel partner the Company lost.
	International sales accounted for approximately 3%, 5% and 12% of the Company’s total revenue for the fiscal years ended September 30, 2013, 2012 and 2011, 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 fiscal years ended September 30, 2013 and 2012, the Company did not make purchases from any one vendor comprising 10% or more of the Company’s total purchases. The Company made purchases from one vendor that comprised approximately 13% of the Company’s total purchases for the fiscal year ended September 30, 2011. 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.

	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, expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, management reviews its estimates based upon currently available information. Actual results could differ materially from those estimates.
Net Loss Per Share	'
	Net Loss Per Share
	The Company calculates net income (loss) per share in accordance with FASB ASC Topic 260, Earnings Per Share. Basic net income (loss) per share is based on the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share also gives effect to all potentially dilutive securities outstanding during the period, such as options, warrants and restricted stock units (“RSUs”), if dilutive. In a period with a net loss position, potentially dilutive securities are not included in the computation 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.
	At September 30, 2013, 2012 and 2011, the following potentially dilutive common shares were excluded from the net loss per share calculation, as they would have been antidilutive:
		2013			2012			2011
	Stock options		2,824,964			3,512,286			4,553,904

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. 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.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	Cash and cash equivalents are defined as highly liquid financial instruments with original maturities of three months or less. A substantial portion of the Company’s cash is deposited with one financial institution. The Company monitors the financial condition of this financial institution and does not believe that funds on deposit are subject to a significant degree of risk.
Investments	'
	Investments
	Investments consist of corporate notes and bonds, and commercial paper. The Company classifies investments as available-for-sale at the time of purchase and reevaluates such classification as of each balance sheet date. All investments are recorded at estimated fair value. Unrealized gains and losses for available-for-sale securities are included in accumulated other comprehensive income, a component of stockholders’ equity. The Company evaluates its investments to assess whether those with unrealized loss positions are other than temporarily impaired. Impairments are considered to be other-than-temporary if they are related to deterioration in credit risk or if it is likely that the Company will sell the securities before the recovery of its cost basis. Realized gains and losses and declines in value judged to be other-than-temporary are determined based on the specific identification method and are reported in other income (expense), net in the Statements of Operations. No other-than-temporary impairment charges were recognized in the fiscal years ended September 30, 2013, 2012 and 2011.
	All investments whose maturity or sale is expected within one year are classified as “current” on the balance sheet. All other securities are classified as “long-term” on the balance sheet.
Fair Value Measurements	'
	Fair Value Measurements
	The carrying amounts of cash equivalents, investments, accounts receivable, accounts payable and other accrued liabilities are considered representative of their respective fair values because of the short-term nature of those instruments.
Accounts Receivable and Allowance for Doubtful Accounts	'
	Accounts Receivable and Allowance for Doubtful Accounts
	Accounts receivable, net, is as follows (in thousands):
		September 30,			September 30,
		2013			2012
	Accounts receivable	$	1,506,627		$	1,115,084
	Less: Allowance for doubtful accounts		(12,000	)		(17,773	)
	Accounts receivable, net	$	1,494,627		$	1,097,311
	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. The Company had no write-offs of the allowance for doubtful accounts for the years ended September 30, 2013 and 2012, respectively.
Deferred Maintenance Fees	'
	Deferred Maintenance Fees
	Deferred maintenance fees consist of capitalized costs associated with software maintenance fees paid to vendors who supply licenses and maintenance for software embedded in the Company’s products that it sells to customers. These software maintenance fees, which are included in other current assets on the balance sheet, are typically billed annually to the Company and are amortized to cost of revenue-maintenance and professional services in the Statements of Operations over the maintenance period, which is typically one year.
Property and Equipment	'
	Property and Equipment
	Property and equipment are carried at cost. The following is a summary of property and equipment as of September 30, 2013 and 2012:
		2013			2012
	Property and equipment—at cost:
	Equipment	$	1,054,868		$	684,552
	Furniture and fixtures		227,189			130,559
	Leasehold improvements		975,838			65,227
			2,257,895			880,338
	Less: accumulated depreciation and amortization		(628,231	)		(460,223	)
	Construction in progress		—			70,964
	Total property and equipment, net	$	1,629,664		$	491,079
	Depreciation and amortization of property and equipment are provided using the straight-line method over estimated useful lives ranging from three to five years. Leasehold improvements are amortized over the lease term. Depreciation and amortization of property and equipment totaled $323,383, $140,146 and $42,133 for the fiscal years ended September 30, 2013, 2012 and 2011, respectively. Included in property and equipment as of September 30, 2013 and 2012 in the table above is equipment of $95,388 purchased under a capital lease. There were no fixed assets acquired under capital leases at September 30, 2011. Depreciation expense related to the equipment purchased under the capital lease was $19,078 and $17,488 in the fiscal years ended September 30, 2013 and 2012, respectively, and accumulated depreciation was $36,566 and $17,488 at September 30, 2013 and 2012, respectively. The Company recorded no depreciation expense related to capital leases in the fiscal year ended September 30, 2011, nor was there any related accumulated depreciation at September 30, 2011. Expenditures for repairs and maintenance are charged to operations. Total repairs and maintenance expenses were $97,532, $57,815 and $43,115 for the fiscal years ended September 30, 2013, 2012 and 2011, respectively.
Long-Lived Assets	'
	Long-Lived Assets
	The Company evaluates the carrying value of long-lived assets, including license agreements and other intangible assets, when events and circumstances indicate that these assets may be impaired or in order to determine whether any revision to the related amortization periods should be made. This evaluation is based on management’s projections of the undiscounted future cash flows associated with each product or asset. If management’s evaluation indicates that the carrying values of these intangible assets were impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. The Company did not record any impairment for the fiscal years ended September 30, 2013, 2012 and 2011.
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 fiscal years ended September 30, 2013 and 2012, no software development costs were capitalized because the time period and cost incurred between technological feasibility and general release for all software product releases were not material.
	The Company evaluates its capitalized software development costs at each balance sheet date to determine if the unamortized balance related to any given product exceeds the estimated net realizable value of that product. Any such excess is written off through accelerated amortization in the quarter in which it is identified. Determining net realizable value, as defined by FASB ASC Topic 985-20, Accounting for the Costs of Software to Be Sold, Leased or Otherwise Marketed, requires making estimates and judgments in quantifying the appropriate amount to write off, if any. Actual amounts realized from the software products could differ from those estimates. Also, any future changes to the Company’s product portfolio could result in significant increases to its cost of license revenue as a result of the write-off of capitalized software development costs.
	The Company recorded no amortization of software development costs for the fiscal year ended September 30, 2013. The Company recorded amortization of software development costs of $91,438 and $137,157 for the fiscal years ended September 30, 2012 and 2011, respectively. The Company records amortization of software development costs as cost of revenue-software in the Statements of Operations.
Deferred Revenue	'
	Deferred Revenue
	Deferred revenues represent advance payments or billings for software licenses, professional services and maintenance billed in advance of the time we recognize the related revenues. Deferred maintenance revenue represents customer billings, paid up front, generally annually at the beginning of each maintenance period, with revenue recognized ratably over such period. For certain other licensing arrangements, revenue attributable to undelivered elements, including post-contract customer support which typically includes telephone support and the right to receive unspecified upgrades and enhancements of software on a when-and-if-available basis, is based upon the sales price of those elements when sold separately and is recognized ratably on a straight-line basis over the term of the arrangement.
Guarantees	'
	Guarantees
	In the ordinary course of business, the Company is not subject to potential obligations under guarantees that fall within the scope of FASB ASC Topic 460, Guarantees (“ASC 460”), except for standard indemnification and warranty provisions that are contained within many of the Company’s customer license and service agreements and certain supplier agreements, and give rise only to the disclosure requirements prescribed by ASC 460. Indemnification and warranty provisions contained within the Company’s customer license and service agreements and certain supplier agreements are generally consistent with those prevalent in the Company’s industry. The Company has not historically incurred significant obligations under customer indemnification or warranty provisions and does not expect to incur significant obligations in the future. Accordingly, the Company does not maintain accruals for potential customer indemnification or warranty-related obligations.
Income Taxes	'
	Income Taxes
	The Company accounts for income taxes in accordance with FASB ASC Topic 740, Income Taxes (“ASC 740”). Deferred tax assets and liabilities arise from temporary differences between the tax bases of assets and liabilities and their reported amounts in the financial statements that will result in taxable or deductible amounts in future years.
	Management evaluates the available evidence about future taxable income and other possible sources of realization of deferred tax assets. The valuation allowance reduces deferred tax assets to an amount that represents management’s best estimate of the amount of such deferred tax assets that more likely than not will be realized. See Note 5 for additional details.
	The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax positions will be sustained on examination by the tax authorities, based on the technical merits of the position. The tax benefit is measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company recognizes interest and penalties related to income tax matters in income tax expense. See Note 5 for additional details.
Stock-Based Compensation	'
	Stock-Based Compensation
	The Company records stock-based compensation in accordance with FASB ASC Topic 718, Compensation-Stock Compensation (“ASC 718”). The Company estimates the fair value of stock options using the Black-Scholes option pricing model. The fair value of stock options granted is recognized as an expense over the requisite service period. Stock-based compensation expense for all share-based payment awards is recognized using the straight-line single-option method.
	The Black-Scholes option pricing model requires subjective assumptions, including future stock price volatility and expected time to exercise, which greatly affect the calculated values. The expected term of options granted is derived from historical data on employee exercises and post-vesting employment termination behavior. The risk-free rate selected to value any particular grant is based on the U.S. Treasury rate that corresponds to the expected life of the grant effective as of the date of the grant. The expected volatility is based on the historical volatility of the Company’s stock price. These factors could change in the future, affecting the determination of stock-based compensation expense in future periods.
Advertising Expense	'
	Advertising Expense
	Advertising costs are expensed as incurred and totaled $123,905, $72,053 and $76,026 during the fiscal years ended September 30, 2013, 2012 and 2011, respectively.
Research and Development	'
	Research and Development
	Research and development costs are expensed in the period incurred.
Leases	'
	Leases
	Leases are reviewed and classified as capital or operating at their inception. For leases that contain rent escalations, the Company records the total rent payable on a straight-line basis over the term of the lease. The difference between rent payments and straight-line rent expense is recorded as deferred rent.
Segment Reporting	'
	Segment Reporting
	FASB ASC Topic 280, Segment Reporting, requires the use of a management approach in identifying segments of an enterprise. During the fiscal year ended September 30, 2013, management determined that the Company has only one operating segment: the development, sale and service of our proprietary software solutions related to mobile imaging.
Comprehensive Loss	'
	Comprehensive Loss
	Comprehensive loss consists of net loss and unrealized gains and losses on available-for-sale securities. The following table summarizes the components of comprehensive loss for the fiscal years ended September 30, 2013, 2012 and 2011:
		2013			2012			2011
