ABSTRACT:
An electronic system verifies that an article has been tagged with an electronic article surveillance marker. The marker includes a resonant circuit for use in detecting the presence of the article by receiving an interrogation signal and returning a response signal. In the system, the physical presence of an article is detected using an article presence detector which outputs an article presence signal upon physical detection thereof. An interrogation zone is monitored with an interrogator for disturbances in the form of a response signal caused by the presence of a marker within the interrogation zone. The interrogator outputs an interrogator output signal when a marker is detected in the interrogation zone. The article presence signals and the interrogator output signals are received in a processor. After an article presence signal is received from a newly physically detected article, the processor determines whether an interrogator output signal is received as a result of an interrogation of the newly physically detected article. The processor outputs either a first or second output signal depending upon whether after an article presence signal is received from a newly physically detected article, the processor receives an interrogator output signal as a result of an interrogation of the newly physically detected article.
