Abstract
A communication station (1) for contactless communication with at least one transponder (2) contains station identification-generating means (7) by means of which a station identification signal (SIDB) can be generated, which can be delivered to the transponder (2) and which can be analyzed in the transponder (2), for which purpose the transponder(2) has station identification signal detection means (45) and station identification signal storage means (46) and station identification signal comparison means (47).
Claims10
A communication station (1),
- which is designed for contactless communication with at least one transponder (2) and
- which has inquiry signal generating means (5) for the generation of at least one inquiry signal (IDB, LDB, SDB) for at least one transponder (2) and
- which has response signal detection means (8) for the detection of at least one response signal (ADB) transmitted to the communication station (1) by a transponder (2) and
- which has transmission means (17) for the delivery of the minimum of one inquiry signal (IDB, LDB, SDB) to the minimum of one transponder (2) and for the reception of the minimum of one response signal (ADB) transmitted to the communication station (1) by a transponder (2),
- characterized in that additional station identification signal generating means (7) are provided, by means of which at least one station identification signal (SIDB;
- SIDB1, SIDB2) can be generated, which can be delivered to at least one transponder (2) by transmission means (17) and by means of which the identity of the communication station (1) can be communicated to least one transponder (2).
