摘要： 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.
