The one thing appears to be a RFID tag of some sorts, and the other is a antitheft device that triggers those alarm things at the door of many stores.

Exactly as Steve says. They work as air coils with at least dual resonating natural frequencies activated by RF AC in large diameter windings placed in around the Exit.

A simple radio like detector sets of an alarm when it hears a resonance.

The cashier has a means to permanently turn the air coil when you pay for the product :-)

They are antitheft devices, they would trigger alarms if you left the store without paying for them....
