Deactivation for Magnetomechanical Marker Used in Electronic Article Surveillance

摘要

A marker for use in a magnetomechanical electronic article surveillance system is described. The EAS marker includes at least one resonator, a housing configured to provide a cavity for vibration of the at least one resonator, a first, magnetized, biasing element configured to provide a biasing magnetic field for the at least one resonator, and a second, non-magnetized, biasing element.
