Abstract
An article control system has an encoded marker associated with an article appointed for passage through an interrogation zone. The marker resonates upon interrogation to provide a signal which is detected and compared against a code list containing at least one predefined code. A signal generated upon verification of parity between marker resonance and the predefined code triggers an alarm or actuates a gating mechanism adapted to redirect the article.
