How do the small security tags (usually stuck on with adhesive) work on things in supermarkets, like meats, dvds etc?
They don’t get removed after purchase, so how come that individual item doesn’t set of the alarms even though the tag is still on it?
In: Technology
At checkout the tags are passed over the deactivation system that is usually built into the register scanner. Once that tag is deactivated it won’t alarm when you exit and the tag can’t be reused.
