Ukash was a form of currency for e-commerce. Users purchased Ukash vouchers for real money, and then used those vouchers to make purchases online. Ukash was available for financial transactions with approximately 420,000 online merchants, but could not be used to conduct person-to-person transactions. The Ukash service was acquired by the Skrill Group in 2014, and merged into their PaySafeCard online purchasing system. All unused Ukash vouchers expired in October 2015.
