Abstract
The invention concerns a method for supporting cashless payment as well as a payment interworking server, a mobile terminal and a computer program product for a cashless payment system. A mobile subscriber identity stored in the subscriber identification module of the mobile terminal is sent to a payment interworking unit. The payment interworking unit transmits the mobile subscriber identity to an authentication server of a mobile communication system which replies an authentication number and a signed response. The authentication number is sent to the mobile terminal which calculates a signed response and transmits the signed response to the payment interworking server. This server compares the singed responses received from the authentication server and from the mobile terminal and sends a confirmation message to a POS unit or a billing system, if the received signed result is correct.
