ABSTRACT:
A radio-frequency identification (RFID) and an electronic article surveillance (EAS) tag includes an RFID device and an EAS device. The RFID device may operate in a plurality of states including an activated state in which communication with a reader is enabled and a deactivated state in which communication with a reader is disabled. The EAS device may operate in a plurality of states including an activated state in which activation of an alarm is enabled and a deactivated state in which activation of an alarm is disable. The RFID device may be deactivated when the EAS device is deactivated. For example, the same piece of equipment that deactivates the EAS device also deactivates the RFID device at the same time. The RFID device may include an antenna, an RFID chip connected to the antenna for communicating with a reader, and an active element operatively disposed with respect to the antenna. The active element, which may include a conductive strip or lead, may have an activated state in which the antenna is enabled for communicating with a reader in a far field and a deactivated state in which the antenna is disabled from communicating with a reader in a far field. In addition, the EAS device may include a magnetic resonator and a bias magnet. When activated, the bias magnet may cause or affect the resonator to resonate and the active element to be in the activated state. Further, when deactivated, the bias magnet may cause the active element to be in the deactivated state.
