Summary of Significant Accounting Policies and Practices [Abstract]
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Share-based compensation The Company follows the provisions of ASC Topic 718, Compensation - Stock Compensation, for equity classified awards, which requires the determination of the fair value of the share-based compensation at the grant date and subsequent recognition of the related expense over the period in which the share-based compensation is earned (“requisite service period”). The amount of future compensation expense related to awards of nonvested shares or nonvested share units (“restricted stock”) is based on the market price for Euronet Common Stock at the grant date. The grant date is the date at which all key terms and conditions of the grant have been determined and the Company becomes contingently obligated to transfer equity to the employee who renders the requisite service, generally the date at which grants are approved by the Company's Board of Directors or Compensation Committee thereof. Share-based compensation expense for awards with only service conditions is generally recognized as expense on a “straight-line” basis over the requisite service period. For awards that vest based on achieving annual performance conditions, expense is recognized on a “graded attribution method.” The graded attribution method results in expense recognition on a straight-line basis over the requisite service period for each separately vesting portion of an award. The Company has elected to use the “with and without method” when calculating the income tax benefit associated with its share-based payment arrangements. See Note 15, Stock Plans, for further disclosure.
