Did you know that beer now has RFID tags?
RFID: Radio Frequency Identification
I walked out of Wal-Mart and the buzzer went off for a case of beer that I paid for.
Answers:
Granted that Wal-mart is trying to use RFID technology for inventory purposes, but it sounds like an integrated Sensormatic theft deterrent tag on the item. Its two different systems, the RFID is used mainly on pallets to check in merchandise to the store. Sensormatic is used to set off an alarm on tags that have not been properly deactivated that is leaving the building.
