Abstract
The apparatus for identity verification using a data card contains at least one terminal and a security service station. The terminal(s) and the station are connected to each other via a communication system. The terminal is provided with a central processing unit including a memory, a card reader for reading data from the data card, a sensor or number input device for introducing personal identification information, and a crypto module. The crypto module encrypts and decrypts data received from the memory under the control of the central processing unit. The security service station likewise also contains a central processing unit including a memory, and a crypto module. This station also contains a comparator for comparing personal identification information with reference personal identification information. Both kinds of information are transmitted to the station from the terminal.
