Abstract
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.

Claim 6
Independent Claim
96 words
A method of operating an EAS tag detacher, the method comprising the steps of: placing the detacher in a first mode of operation in which the detacher operates to separate snap-connected elements of an EAS tag only in response to an ID signal generated by the tag; and transmitting a conditioning signal to the detacher to switch the detacher from said first mode of operation to a second mode of operation in which the detacher separates snap-connected elements of an EAS tag presented for separation in the absence of an ID signal generated by the tag.
Claim 7
Independent Claim
96 words
A method of operating an EAS tag detacher, the method comprising the steps of: placing the detacher in a first mode of operation in which the detacher operates to separate snap-connected elements of an EAS tag only in response to an ID signal generated by the tag; and transmitting a conditioning signal to the detacher to switch the detacher from said first mode of operation to a second mode of operation in which the detacher separates snap-connected elements of an EAS tag presented for separation in the absence of an ID signal generated by the tag.
