I just saw a guy shove loads of chocolate bars and candy into a big black bag, get two beers. I got curious cause usually people don’t put stuff they intend to buy into bags.
Then he proceeds to checkout but only pays for the beers, not a single beep from the sensors. Are they only meant to detect certain items or did the homeless guy have something to disrupt the sensors?

From what I know, certain (usually more expensive) items have RFID chips/tags inside them that will trigger the sensors when left unpaid. So normal food items, like vegetables, can’t be tracked but a pack of batteries might be.
