Security Tag Deactivation System Abstract A system for deactivating security tags, which bear a resonant circuit made of conductors on opposite sides of a dielectric. The system deactivates by applying to a tag sufficiently high RF power at the resonance frequency to produce breakthrough between opposed conductors. A tag presence alert signal is intentionally extended beyond the period of active tag presence detection. During high power operation, the system inhibits other nearby RF deactivating and electronic article surveillance systems. The RF transmissions of all these systems may also be slaved. The high power RF produced by the deactivating system is principally dissipated where it causes no undesirable heating effects.
