Abstract (en)
[origin: WO9839743A2] The invention relates to a method for carrying out modifications in authorization data records which are stored on data carriers, especially chip cards, wherein said data carrier is connected to a terminal and a security module for data exchange. The data record which is to be modified is read out in cryptographically secure form by the security module from the data carrier. After authenticating the authorization data, said data is modified in the security module according to instructions issued by the terminal. The modified authorization data is transmitted to the data carrier in cryptographically secure form and is stored in the data carrier after authentication.
