摘要
System for preventing detection stationary identification marker in a detection zone of an electronic article surveillance system. The system includes a transmitter for transmitting an exciter pulse for exciting an identification marker, and a receiver system for receiving a characteristic response energy emitted by an identification marker in an inhibit field of the detection zone and in a main area of said detection zone. A comparator system is provided for generating an alarm condition when the characteristic response energy received in the main area exceeds the characteristic response energy received in the inhibit field by a predetermined threshold value.
