Abstract

An electronic article surveillance (EAS) apparatus is comprised of a carrier and an EAS unit. The carrier receives the EAS unit and has an adhesive element on one of its surfaces to attach to an item to be protected. The EAS unit may have several electronic components including, among others, an EAS coil, a microprocessor, communication elements, a switch, a battery, and an audible alarm generator. The EAS unit can be removed from a protected item by opening, or parting, the carrier. Once the carrier is opened the EAS unit can be retrieved for reuse. External devices can be used to communicate with and disarm the EAS unit. If an EAS unit is removed without being disarmed, a switch detects the change in status and an audible alarm is generated.
