<p>A method for redeeming a plurality of vouchers distributed via portable electronic devices in a single transaction in which a first voucher having a number (1) and a cash value (3) is entered into a standards compliant POS terminal (9), which generates a standards compliant validation request message (15) and sends it to an acquirer (14) which in turn forwards it to a service provider (6). The message is then authenticated. If the voucher number (1) is valid, a flag (16) in the message (15) is set to "pre-authorised". The service provider (6) searches for additional vouchers associated with the voucher and generates a pre-authorisation message including the numbers (18, 19) of any additional vouchers. The messages are then transmitted to the terminal (9) to inform the customer (13) accordingly. The customer can then select the vouchers to be redeemed and the terminal (9) sends redemption messages (20, 21) to the service provider (6) which cancels the selected vouchers and generates messages (22, 23) authorising payment corresponding to the vouchers' cash value.</p> |
