SYSTEM AND METHOD FOR SECURELY STORING, GENERATING, TRANSFERRING AND PRINTING ELECTRONIC PREPAID VOUCHERS

摘要

A system and a method that utilizes transaction terminals (125, 121) equipped with smart card readers to download and store multiple prepaid electronic vouchers to a smart card, retrieve and decrypt prepaid vouchers from the smart card and print a voucher receipt with a printer (122). A mobile transaction server (191) acts as a gateway to a prepaid system (190) and routes transactions between transaction terminals (125, 121) and the prepaid system and between transaction terminals. The method includes storing a voucher encryption key on a second smart card or hardware security module. The voucher encryption key is utilized to decrypt encrypted vouchers on a voucher repository smart card. The method also allows for transferring encrypted vouchers between voucher smart cards. The transaction terminals may be mobile devices communicating to the mobile transaction server over wireless networks or computers connected to a wired network.
