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
They either get removed when purchased or are simply deactivated, causing them to not respond to the sensors anymore when you are leaving the store. Where I work, we just have a small device that pops the tags off though.
