Abstract
An electronic article surveillance (EAS) tag incorporates alternative theft deterrence systems. The security tag incorporates both a benefit-denial ink-based system and two independent EAS detection elements operating at two different frequencies such that the tag can alternatively be operated in two different systems. The security tag is further adapted to be reusable after ink ampoule breakage and includes a visual indication of ink to serve as a further visual deterrence to shoplifters.
