Accounting Policies [Abstract]
Consolidation	CONSOLIDATION The consolidated financial statements include the accounts of JHA and all of its subsidiaries, which are wholly-owned, and all intercompany accounts and transactions have been eliminated.
Use of Estimates	USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Revenue Recognition	REVENUE RECOGNITION The Company derives revenue from the following sources: license arrangements, support and service fees (non-software) and hardware sales. There are no rights of return, condition of acceptance or price protection in the Company’s sales contracts. License Arrangements: For software license agreements, the Company recognizes revenue when persuasive evidence of an arrangement exists, delivery of the product or service has occurred, the fee is fixed and determinable and collection is probable. For arrangements where the fee is not fixed or determinable, revenue is deferred until payments become due. The Company’s software license agreements generally include multiple products and services or “elements.” Generally, none of these elements are deemed to be essential to the functionality of the other elements. For multiple element arrangements, which contain software elements and non-software elements, we allocate revenue to the software deliverables and the non-software deliverables as a group based on the relative selling prices of all of the deliverables in the arrangement. For our non-software deliverables, we allocate the arrangement consideration based on the relative selling price of the deliverables using estimated selling price ("ESP"). For our software elements, we use VSOE for this allocation when it can be established and ESP when VSOE cannot be established. The selling price for each element is based upon the following selling price hierarchy: VSOE if available, third party evidence ("TPE") if VSOE is not available, or ESP if neither VSOE or TPE are available. Generally, we are not able to determine TPE because our go-to-market strategy differs from that of our peers and our offerings contain a significant level of differentiation such that the comparable pricing of products with similar functionality cannot be obtained. ESP is determined after considering both market conditions (such as the sale of similar products in the market place) and entity-specific factors (such as pricing practices and the specifics of each transaction). For our non-software deliverables, a delivered item is accounted for as a separate unit of accounting if the delivered item has standalone value and if the customer has a general right of return relative to the delivered item, delivery or performance of the undelivered item is probable and substantially within the vendor’s control. For our software licenses and related services, including the software elements of multiple-element software and non-software arrangements, U.S. GAAP generally require revenue earned on software arrangements involving multiple elements to be allocated to each element based on vendor-specific objective evidence (“VSOE”) of fair value. VSOE of fair value is determined for implementation services based on a rate per hour for stand-alone professional services and the estimated hours for the bundled implementation, if the hours can be reasonably estimated. VSOE of fair value is determined for post-contract support ("PCS") based upon the price charged when sold separately. For a majority of the elements within our software arrangements, we have determined that VSOE cannot be established; therefore, revenue on our software arrangements is generally deferred until the only remaining element is post-contract support ("PCS"). At that point, the entire arrangement fee is recognized ratably over the remaining PCS period, assuming that all other criteria for revenue recognition have been met. The amounts deferred are included in the balance sheet as deferred revenue and recognized to Bundled Products & Services revenue within Support & Service revenue in the income statement. For arrangements that include specified upgrades, such upgrades are accounted for as a separate element of the arrangement. For those specified upgrades for which VSOE of fair value cannot be determined, revenue related to the software elements within the arrangement is deferred until such specified upgrades have been delivered. Total revenue recognized ratably related to our Bundled Products & Services was $60,685, $64,275 and $73,942 for the years ended June 30, 2014, 2013, and 2012, respectively. Support and Service Fee Revenue (Non-software): Maintenance support revenue contracted for outside of a license arrangement is recognized pro-rata over the contract period, typically one year. Outsourced data processing and ATM, debit card, and other transaction processing services revenue is recognized in the month the transactions are processed or the services are rendered. Hardware Revenue: Hardware revenue is recognized upon delivery to the customer, when title and risk of loss are transferred. In most cases, we do not stock in inventory the hardware products we sell, but arrange for third-party suppliers to drop-ship the products to our customers on our behalf. The Company also remarkets maintenance contracts on hardware to our customers. Hardware maintenance revenue is recognized ratably over the agreement period. Revenue-based taxes collected from customers and remitted to governmental authorities are presented on a net basis (i.e. excluded from revenues).
Deferred Costs	Costs for certain software and hardware maintenance contracts with third parties, which are prepaid, are recognized ratably over the life of the maintenance contract, generally one to five years, with the related revenue amortized from deferred revenues. Direct and incremental costs associated with arrangements subject to Accounting Standards Codification ("ASC") 985-605 (for which VSOE of fair value cannot be established) are deferred until the only remaining element in the revenue arrangement is PCS at which point the costs are recognized ratably over the remaining PCS period with the related revenue. Direct and incremental costs associated with arrangements not subject to ASC 985-605 consist primarily of certain up-front costs incurred in connection with our software hosting arrangements and are recognized ratably over the contract period which typically ranges from 5-7 years. These costs include commissions, costs of third-party licenses and the direct costs of our implementation services, consisting of payroll and other fringe benefits.
Deferred Revenues	DEFERRED REVENUES Deferred revenues consist primarily of prepaid annual software support fees, deferred bundled software arrangements revenue, and prepaid hardware maintenance fees. Deferred bundled software arrangements revenue and hardware maintenance contracts may be recognized over multiple years; therefore, the related deferred revenue and maintenance are classified in accordance with the terms of the contract. Software and hardware deposits received are also reflected as deferred revenues. The vast majority of our maintenance (PCS) renews annually and runs from July 1 to June 30. Renewal billings are submitted to customers each June and the Company has the right to bill at that date; therefore we include those billings as gross in deferred revenue and as a receivable on our balance sheet at the end of each fiscal year.
Computer Software Development	COMPUTER SOFTWARE DEVELOPMENT The Company capitalizes new product development costs incurred from the point at which technological feasibility has been established through the point at which the product is ready for general availability. Software development costs that are capitalized are evaluated on a product-by-product basis annually and are assigned an estimated economic life based on the type of product, market characteristics, and maturity of the market for that particular product. These costs are amortized based on current and estimated future revenue from the product or on a straight-line basis, whichever yields greater amortization expense. All of this amortization expense is included within Cost of support and service.
Cash Equivalents	CASH EQUIVALENTS The Company considers all highly liquid investments with maturities of three months or less at the time of acquisition to be cash equivalents.
Property and Equipment	PROPERTY AND EQUIPMENT AND INTANGIBLE ASSETS Property and equipment is stated at cost and depreciated using the straight-line method over the estimated useful lives of the assets.
Intangible Assets	Intangible assets consist of goodwill, customer relationships, computer software, and trade names acquired in business acquisitions in addition to internally developed computer software. The amounts are amortized, with the exception of those with an indefinite life (such as goodwill), over an estimated economic benefit period, generally five to twenty years. The Company reviews its long-lived assets and identifiable intangible assets with finite lives for impairment whenever events or changes in circumstances have indicated that the carrying amount of its assets might not be recoverable. The Company evaluates goodwill and other indefinite-lived intangible assets for impairment of value on an annual basis as of January 1 and between annual tests if events or changes in circumstances indicate that the asset might be impaired.
Reportable Segment Information	REPORTABLE SEGMENT INFORMATION In accordance with U.S. GAAP, the Company's operations are classified as two reportable segments: bank systems and services and credit union systems and services (see Note 13). Revenue by type of product and service is presented on the face of the consolidated statements of income. Substantially all the Company’s revenues are derived from operations and assets located within the United States of America.
Common Stock	COMMON STOCK The Board of Directors has authorized the Company to repurchase shares of its common stock. Under this authorization, the Company may finance its share repurchases with available cash reserves or short-term borrowings on its existing credit facilities. The share repurchase program does not include specific price targets or timetables and may be suspended at any time. At June 30, 2014, there were 19,795 shares in treasury stock and the Company had the remaining authority to repurchase up to 5,196 additional shares. The total cost of treasury shares at June 30, 2014 is $577,781. During fiscal 2014, the Company repurchased 3,041 treasury shares for $175,699. At June 30, 2013, there were 16,754 shares in treasury stock and the Company had authority to repurchase up to 8,237 additional shares. Dividends declared per share were $0.84, $0.56, and $0.44 for the years ended June 30, 2014, 2013, and 2012, respectively.
Earnings Per Share	EARNINGS PER SHARE Per share information is based on the weighted average number of common shares outstanding during the year. Stock options have been included in the calculation of income per diluted share to the extent they are dilutive. The difference between basic and diluted weighted average shares outstanding is the dilutive effect of outstanding stock options (see Note 10).
Income Taxes	INCOME TAXES Deferred tax liabilities and assets are recognized for the tax effects of differences between the financial statement and tax bases of assets and liabilities. A valuation allowance would be established to reduce deferred tax assets if it is more likely than not that a deferred tax asset will not be realized. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based upon the technical merits of the position. The tax benefits recognized in the financial statements from such a position is measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. Also, interest and penalties expense are recognized on the full amount of deferred benefits for uncertain tax positions. Our policy is to include interest and penalties related to unrecognized tax benefits in income tax expense.
