Abstract
A detacher unit for disengaging a combination EAS/RFID tag from its article. The detaching unit detaches the spring clamp mechanism of a combination EAS/RFID tag when the tag is placed within a particular region within the detaching unit. A near field magnetic loop antenna is situated within the placement region in a housing. When the combination EAS/RFID tag is placed within the placement region just above the near field magnetic loop antenna, the RFID code of the tag is read and the detachment unit releases the clamp mechanism that attaches the EAS/RFID tag to its article.
