If so, which companies offer such a tag?
Yes. Checkpoint Systems, a leading provider of electronic article surveillance (EAS) and radio frequency identification systems, offers a combination tag (see Checkpoint Combines EAS Tags With RFID). And ADT, which acquired EAS provider Sensormatic years ago, also offers a tag that combines EAS and RFID technologies (see RFID News Roundup: ADT Europe Develops RFID-EAS System).
Tagit-EAS and RFID company Truecount have teamed up to develop and market the Circumvention Resistant RFID (CRRFID) tag, which combines RFID and EAS technologies. The CRRFID tag will contain an EPC Gen 2 passive ultrahigh-frequency (UHF) RFID inlay and an electromagnetic (EM) EAS wire, resulting in a multifunction tag that will not only set off alerts at a store's exit in the event that an unpurchased item bearing that tag is removed, but also provide data regarding the product being taken. The tag can also be used to track inventory from the point of manufacture to the point of sale (see Tagit-EAS, Truecount Work on Circumvention Resistant RFID Tag).
In addition, UPM Raflatac produces a series of four EPC Gen 2 UHF tags, targeted to the retail market, that have RFID chips with built-in EAS capabilities. The tags can be read by any EPC Gen 2 interrogator, and can have the EAS function turned on and off by the same RFID reader (see Raflatac Releases RFID Tags With Built-In EAS).
