1. An actuation device, said actuation device having:
- a housing, said housing having a slot for receiving a data-carrying card;
an electronically actuated control unit disposed in said housing for regulating a device;
a signal evaluation unit disposed in said housing for receiving data signals received as a consequence of the reading of a data-carrying card, said signal evaluation unit configured to, based on the received data signals, selectively generate an actuation signal to said control unit to regulate the operation of said control unit;
a cover separate from said housing that is disposed over said housing, said cover positioned over said housing to extend over the housing slot;
a transponder reader unit, said transponder reader unit comprising;
an antenna mounted to said cover to receive signals from a transponder external to said housing and said cover; and
a signal processing circuit disposed in said housing and connected to said signal evaluation unit, said signal processing circuit configured to;
receive signals from said antenna;
convert the signals from said antenna into a form in which said signal evaluation unit can evaluate the signals; and
forward the converted signals to said signal evaluation unit; and
an electrical connector mounted to said cover, wherein said antenna is connected to said electrical connector and said electrical connector applies the signals from said antenna to said signal processing circuit.

Abstract
An actuation device, for example for a door lock, is capable of actuation by a control unit which can be initiated by a transponder reader unit, said control unit being connected to a magnetic signal evaluation unit. The transponder reader unit generates signals which correspond to the signals of a magnetic card read head, for the initiation of the magnetic signal evaluation unit.
