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?

Stickers and such need to be deactivated at the register. You probably don’t even notice it, but your cashier runs it across a pad or other such scanner and it deactivates. If it hasn’t been deactivated, it’ll set off the alarm.
