摘要

The invention relates to a device (10) for monitoring a occupancy - state of a parking space with a processing unit (20) and a first wireless communication unit (31), which is adapted, with a first external unit (41) to communicate in a first frequency range.The core of the invention is that the device a second, wireless communication unit (32), which is adapted, with a second external unit (42) to communicate in a second frequency range, which is different from the first frequency range. In addition, the processing unit (20) configured for this purpose, first authentication data (51) of the first unit (41) by means of the first communication unit (31) to receive and with second, stored authentication data (52) to compare. Furthermore, the processing unit (20) is adapted, in the case of the first and second authentication data (51, 52) a signal (60) by means of the second communication unit (32), which indicates a wrong parker.In addition, the invention relates to a method for operating such a device (10).n="17"
