Abstract
A coded marker in a magnetomechanical resonant electronic article identification system, includes a plurality of ductile magnetostrictive elements or strips based on an amorphous magnetic alloy ribbon with improved magnetomechanical resonance performance. The coded marker takes full advantage of the improved magnetomechanical properties, and an electronic article identification system utilizes the coded marker. The improved encodable and decodable marker/identification system is capable of identifying considerably larger number of articles than conventional systems.
