Electronic detection system for detecting antitheft and/or identification labels

摘要

An electronic system for detecting antitheft and/or identification labels, comprising a number of electronic antitheft and/or identification labels which can operatively be attached to goods to be secured or registered or can be worn by a person or animal to be registered and/or identified, transmitting and receiving means for generating an electromagnetic interrogation field in a detection zone and for detecting one of the labels which is located in the interrogation field, characterized in that the system is further provided with measuring means for measuring a Q factor and/or a resonance frequency of one of the labels and/or for measuring a Q factor and/or resonance frequency of an environment of the detection zone.
