Abstract
A device for removing reusable "hard" EAS tags from articles of merchandise is controlled so as to operate in response to identification data generated by an RFID element in the hard tag. A transmitter-key device is provided to selectively condition the detaching unit to operate in the absence of the otherwise required identification data. The transmitter-key device may also be used to turn the detaching unit on and off. Data indicative of the identity of the holder of the transmitter-key device may be stored in the detaching unit or an associated point-of-sale terminal to log detaching transactions authorized by the transmitter-key device.
