Abstract
The present invention describes a device and a procedure for the user-controlled release of chip-card functions in particular through the input of authentication data. The input of the authentication data takes place by way of an input device of a mobile chip-card reader, particularly one designed as a pocket chip-card reader. The authentication data are checked in the chip-card on the basis of a reference list. If the authentication data agree with the reference-data, a function stored in the non-volatile memory of the chip-card is released. The released function can be specified by number, time and period of validity. The chip-card can then be used in a terminal in accordance with the specified release. The present invention thereby guarantees in a simple manner, that authentication data cannot leave the area under the control of the user's chip-card. Moreover, the authentication ensures that only functions released by the authorization such as, for example, the production of a signature or read or write commands, are executed.
