An RFID tag (or less reliable is a dumb RF tag as anti-theft only) can stop shoplifting and do inventory control; those are very cheap and don't need the manufacturer to add something. A BT system is about 100x more expensive and no better, maybe even worse. So there is some other reason for this system than the stated one, or the article is wrong and it's simply an RFID tag to create an alarm and nothing is disabled. Anyway how would BT disable a tool that wouldn't be easily circumvented? I'd think it more believable if it was some expensive gadget that already has embedded BT.
