Abstract
A method for carrying out a transaction between a portable data carrier, such as a chip card, and a terminal is described. An information item (TID) about the terminal is transferred to the portable data carrier upon the transmission of transaction data by a communication between the portable data carrier and the terminal. As a result, the portable data carrier obtains from the information item a locational position (ZID, WID, GID) of the terminal. Further, there is ascertained a locational position (OP) of the portable data carrier to which the portable data carrier has access. Finally, the portable data carrier compares the locational position (ZID, WID, GID) of the terminal with its locational position (OP), and initiates a measure for protecting the transaction in case a deviation between the two locational positions (ZID, WID, GID; OP) exceeds a predetermined threshold.
