RF induction readers that send out a radio signal that induces a current in the card, that then sends back a low power RF response.
no they are credit cards with a chip in them. all you do is hold the card up to this thing and it reads your credit card info without it being swiped or inserted into anything. my ex used to leave his card in his wallet and his wallet in his pants and hold his behind up to the gas pump and it read his card. lol
