Abstract:
A reading device for contactless communication with a transponder unit includes a first antenna for generating a reading device field in the form of an alternating magnetic field. The reading device further contains one or more second antennas configured, and arranged in relation to the first antenna, such that during a contactless communication of the reading device with a transponder unit which generates communication signals by means of load modulation, a predetermined change of a detection signal is captured on the second antenna or antennas if the transponder unit is located in a predetermined zone around the reading device.
