ELECTRONIC ARTICLE SURVEILLANCE RELAY DEVICE

摘要

An electronic article surveillance device attaches to an object having an electronic article surveillance RFID label in it. The EAS device interrogates the label for information and associates itself with the label. The device retransmits the information from the label to the broader system and over a longer range than the label can by itself. The device has a motion detector and periodically interrogates the label to insure the presence of the label, especially when motion is detected. The unexpected absence of the label is considered an alarm condition and the device will alarm in those circumstances. External devices arm and disarm the device and detach the device as well.
