Do the alarms at the exits of grocery stores such as Jewel Osco really work? - walgreens alarm went off
It seems that when I am in the supermarket I see kids stealing a candy bar or pack of gum out of the box and go through the detectors at the exit from the sensors without bin. Sometimes I think people use the program around and put items in their luggage without paying for scanning and not for everything. In addition, leave without sensors.
So after I happened almost every time I Jewel Osco, I want to know if the sensors in the doors actually work for something or not in supermarkets and stores like Walgreens. I know who work in electronics stores like Best Buy a special day, which have triggered the alarm, but not products like bread, shaving cream, candy, or?
WHat is the point of these sensors, when people steal work in grocery stores? Are there some things that trigger such alerts or what?

The sensors are not content to distinguish to magically all the goods from the gate and then the alarm.
Using RFID tags, labels too small to respond to a signal from the sensor. Just the labels on the products more expensive. Often, when opening a package that will be a small plastic container is affixed within the packaging. This is the RFID tag, and could have had stored there by the manufacturer.
