Abstract:
A radio frequency detection system is provided that includes at least two radio frequency detection devices, which have an antenna each with a detection range for a radio frequency identification and detect the radio frequency identification information provided in the detection range. The radio frequency detection system is designed to attenuate a detection range of a detecting radio frequency detection device in the detection range of the at least one other radio frequency detection device by means of a compensation member such that the radio frequency identification cannot be detected by the detecting radio frequency detection device in the detection area of the at least one other radio frequency detection device. The compensation member feeds a compensation current to the at least one other antenna to generate an opposing magnetic field, which attenuates or extinguishes the magnetic field of the detecting antenna in the at least one other detection range, by the at least one other antenna in the at least one other detection range.
