I see these sensormatic tags in almost everything these days, but I'm still really confused on how they work. How can they be activated and deactivated by just sliding them across one of those counter deactivators? Do they have some sort of battery in each one. Wounldn't that be expensive? Do they work with magnets?
How do sensormatic tags work?
I know something you don't know! Hehe. Anyways, why do you want to know? Probably not for a good reason.
