Abstract:
A method for executing transactions that are protected by a chip card, comprising the steps of:connecting one chip card of a plurality of possible types of chip cards to a terminal;determining a code for a transaction procedure according to which the transaction is to be carried out, the code being determined by an operating program in the terminal after the one chip card is connected to the terminal;determining a network address of a corresponding transactor of a plurality of transactors from the code of the transaction procedure, said corresponding transactor corresponding to said one chip card;setting up a connection from said terminal to the corresponding transactor through a data network by the operating program, said connection being protected by cryptographic methods; andsubsequently implementing the transaction by bi-directional communication between the chip card and the corresponding transactor;connecting said corresponding transactor to a host;providing a security module in said corresponding transactor; andproviding a secure transaction between said corresponding transactor and said host using said security module.
