The invention relates to a radio-frequency detection system with at least two radio-frequency detection devices, which each have an aerial with a detection range for a radio-frequency marking and are each designed to detect the radio-frequency marking and marking information made available by the latter in the detection range. The invention is characterised in that the radio-frequency detection system is designed to weaken 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 compensating element, in such a way that the radio-frequency marking cannot be detected by the detecting radio-frequency detection device in the detection range of the at least one other radio-frequency detection device. The compensating element is designed to feed a compensating current into the at least one other aerial and thus to generate a magnetic opposing field by means of the at least one other aerial in the at least one other detection range, which magnetic opposing field weakens or suppresses the magnetic field of the detecting aerial in the at least one other detection range.
