A method of redeeming an electronic voucher using a standards compliant top up or EFTPOS terminal. A cash value voucher comprising an alphanumeric string and a cash value is sent to a mobile phone and to redeem the voucher the alphanumeric string is entered at the top up terminal. The voucher is then validated by the terminal, depending on the parameters specified by the host system. Normally these will be: <SL> <LI>1. Is the Voucher Number valid? Y/N <LI>2. Has the Voucher Number been used before/does it have any "balance of uses" left against it? Y/N </SL> If validated both parameters will have a Y parameter and the voucher then represents a cash value. |
