How do the retail shop theft alarms work?

464 viewsOther

I bought a dress from a mainstream shop. The item didn’t have a tag on nor a price tag, so the cashier had to manually enter the price. When I left the store the alarm didn’t set off but a machine that the security guy was holding started beeping. He approached me, showed me a tablet that had the item I bought on and asked me if I have a receipt for it , which I did, but I had to walk in and out the store again until the machine stopped beeping.
How does this alarm system work?

A tiny piece of electronics identifies itself to the alarm bars at the doors, and the alarm bars either “just” notice that there is a tag present and starts beeping or they actually identify the alarm tag and tell what security should look for.

The electronics can be an extra sticker on the price tag. A small plastic clip. just a piece of wire and a reeeeeeeeeally small circuit, looks almost like a small needle. Or a bulkier thing that also contains some hard-to-wash paint, so that the paint ruins the piece of clothing if you to remove the alarm.
