1. A transponder communication device for contactless communication with a mobile transponder:
- the transponder communication device comprising;
interrogation means for generating interrogation information in response to which the mobile transponder, when in an active state, generate and transmit answer information;
transmission means for transmitting the interrogation information to the mobile transponder;
receiving means for receiving the answer information;
answer information detection means for detecting the presence of the mobile transponder depending on the occurrence of the answer information;
an operational test transponder detachably secured in the transponder communication device for testing the transponder communication device when mobile transponders are situated within a receiving range of the transponder communication device and the operational test transponder including means for generating and for transmitting operational test information to be received by the receiving means of the transponder communication device;
operational test information detection means connected to the receiving means and configured to detect received operational test information and configured to generate error information when the received operational test information deviates from valid operational test information.

Abstract
A transponder communication device interrogates an operational test transponder that is permanently within a receiving range of the transponder communication device. In response thereto, the operational test transponder sends operational test information to the transponder communication device. The transponder communication device checks whether received operational test information is valid, and generates an error signal if the received operational test information is invalid.
