Description Of Business And Basis Of Presentation [Abstract]
Basis Of Presentation And Summary Of Significant Accounting Policies	1. Basis of Presentation and Summary of Significant Accounting Policies Unaudited Interim Financial Information The accompanying unaudited condensed consolidated financial statements include all majority-owned subsidiaries over which the Company exercises control and have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") and the rules and regulations of the United States Securities and Exchange Commission for Quarterly Reports on Form 10-Q and include all of the information and disclosures required for interim financial reporting. The results of operations for the three and nine months ended March 31, 2018 and 2017, are not necessarily indicative of the results for the full year. The Company believes that the disclosures are adequate to make the information presented not misleading. These financial statements should be read in conjunction with the financial statements, accounting policies and financial notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended June 30, 2017. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments), which are necessary for a fair representation of financial results for the interim periods presented. During the three months ended December 31, 2017, the Company reclassified redeemable common stock out of total equity because redeemable common stock is required to be presented outside of permanent equity. The Company has restated these amounts in its unaudited condensed consolidated balance sheet as at June 30, 2017 and unaudited condensed consolidated statement of changes in equity for the nine months ended March 31, 2018. The reclassification resulted in a decrease in total equity by approximately $107.7 million and an increase in redeemable common stock, presented outside of permanent equity, of approximately $107.7 million. This reclassification had no impact on the Company's previously reported consolidated income, comprehensive income or cash flows.

References to "Net1" are references solely to Net 1 UEPS Technologies, Inc. Recent accounting pronouncements adopted In August 2014, the FASB issued guidance regarding Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern. This guidance requires an entity to perform interim and annual assessments of its ability to continue as a going concern within one year of the date that its financial statements are issued. An entity must provide certain disclosures if conditions or events raise substantial doubt about the entity's ability to continue as a going concern. The guidance is effective for the Company beginning July 1, 2017. The adoption of this guidance did not have a material impact on the Company's financial statements disclosures. In July 2015, the FASB issued guidance regarding Simplifying the Measurement of Inventory. This guidance requires entities to measure most inventory "at the lower of cost and net realizable value," thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost or market (market in this context is defined as one of three different measures). The guidance will not apply to inventories that are measured by using either the last-in, first-out ("LIFO") method or the retail inventory method ("RIM"). The guidance is effective for the Company beginning July 1, 2017. The adoption of this guidance did not have a material impact on the Company's financial statements. In November 2015, the FASB issued guidance regarding Balance Sheet Classification of Deferred Taxes. This guidance requires that deferred tax liabilities and assets are to be classified as non-current in a classified statement of financial position. The current requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount is not affected by the amendments in this update. This guidance is effective for the Company beginning July 1, 2017, and has been applied on a prospective basis. The adoption of this guidance has resulted in the reclassification of current deferred tax assets and liabilities as non-current deferred tax assets and liabilities in the unaudited condensed consolidated balance sheet as of March 31, 2018. Prior period current deferred tax assets have not been reclassified as non-current in the unaudited condensed consolidated balance sheet as of June 30, 2017. In March 2016, the FASB issued guidance regarding Improvements to Employee Share-Based Payment Accounting. The guidance simplifies several aspects of the accounting for employee share-based payment transactions for both public and nonpublic entities, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. This guidance is effective for the Company beginning July 1, 2017. The adoption of this guidance did not have a material impact on the Company's financial statements. The Company has elected to continue to estimate the number of forfeitures when an award is made. Recent accounting pronouncements not yet adopted as of March 31, 2018 In May 2014, the FASB issued guidance regarding Revenue from Contracts with Customers. This guidance requires an entity to recognize revenue when a customer obtains control of promised goods or services in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The guidance was originally set to be effective for the Company beginning July 1, 2017, however in August 2015, the FASB issued guidance regarding Revenue from Contracts with Customers, Deferral of the Effective Date. This guidance defers the required implementation date specified in Revenue from Contracts with Customers to December 2017. Public companies may elect to adopt the standard along the original timeline. The guidance is effective for the Company beginning July 1, 2018. The Company expects that this guidance may have a material impact on its financial statements and is currently evaluating the impact of this guidance on its financial statements on adoption. In January 2016, the FASB issued guidance regarding Recognition and Measurement of Financial Assets and Financial Liabilities. The guidance primarily affects the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. The guidance requires changes in the fair value of the Company's equity investments, with certain exceptions, to be recognized through net income rather than other comprehensive income. In addition, the guidance clarifies the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. This guidance is effective for the Company beginning July 1, 2018, and early adoption is not permitted, with certain exceptions. The amendments are required to be applied by means of a cumulative-effect adjustment on the balance sheet as of the beginning of the fiscal year of adoption. The Company is currently assessing the impact of this guidance on its financial statements disclosure. In February 2016, the FASB issued guidance regarding Leases. The guidance increases transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities on the balance sheet. The amendments to current lease guidance include the recognition of assets and liabilities by lessees for those leases currently classified as operating leases. The guidance also requires disclosures to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. This guidance is effective for the Company beginning July 1, 2019. Early adoption is permitted. The Company expects that this guidance may have a material impact on its financial statements and is currently evaluating the impact of this guidance on its financial statements on adoption. In June 2016, the FASB issued guidance regarding Measurement of Credit Losses on Financial Instruments. The guidance replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. For trade and other receivables, loans, and other financial instruments, an entity is required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses, which reflects losses that are probable. Credit losses relating to available-for-sale debt securities will also be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. This guidance is effective for the Company beginning July 1, 2020. Early adoption is permitted beginning July 1, 2019. The Company is currently assessing the impact of this guidance on its financial statements disclosure. In June 2016, the FASB issued guidance regarding Classification of Certain Cash Receipts and Cash Payments. The guidance is intended to reduce diversity in practice and explains how certain cash receipts and payments are presented and classified in the statement of cash flows, including beneficial interests in securitization, which would impact the presentation of the deferred purchase price from sales of receivables. This guidance is effective for the Company beginning July 1, 2018, and must be applied retrospectively. Early adoption is permitted. The Company is currently assessing the impact of this guidance on its financial statements disclosure. In January 2017, the FASB issued guidance regarding Clarifying the Definition of a Business. This guidance provides a more robust framework to use in determining when a set of assets and activities is a business. Because the current definition of a business is interpreted broadly and can be difficult to apply, stakeholders indicated that analyzing transactions is inefficient and costly and that the definition does not permit the use of reasonable judgment. The amendments provide more consistency in applying the guidance, reduce the costs of application, and make the definition of a business more operable. The guidance is effective for the Company beginning July 1, 2018. Early adoption is permitted. The Company is currently assessing the impact of this guidance on its financial statements disclosure. In January 2017, the FASB issued guidance regarding Simplifying the Test for Goodwill Impairment. This guidance removes the requirement for an entity to calculate the implied fair value of goodwill (as part of step 2 of the current goodwill impairment test) in measuring a goodwill impairment loss. The guidance is effective for the Company beginning July 1, 2020. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently assessing the impact of this guidance. In May 2017, the FASB issued guidance regarding Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting. The guidance amends the scope of modification accounting for share-based payment arrangements and provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under Accounting Standards Codification 718. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. The guidance is effective for the Company beginning July 1, 2018. Early adoption is permitted. The Company is currently assessing the impact of this guidance on its financial statements disclosure.
