摘要
The portable data carrier, e.g. an IC card, has an EEPROM (electrically erasable read only memory) and data input/output equipment is provided for communication with the data carrier. The secret code entered into equipment is compared with the secret code stored on the card, and, if the code entered is false or wrong, the count in the error counter (FBZ) is either increased or decreased by 1. After a certain number of false entries, further processing is automatically blocked.
