What tech/signal do these use?

This is sticker for my monthly membership to a car was. The sticker has on the back of it copper wires and a device that detects it at the wash. However I have it on this sticker and not on my windshield because for some reason my windshield tint blocks it's signal so I need to hold it out my window to work. I was wondering if I could copy it with the flipper and see if that works.
