Here's the latest card from Diamond Mountain Casino in Susanville, CA thatis an RFID-type card that is swiped on the machine instead of being inserted. There is no mag stripe or barcode, and there is no player info printed on the cards. The cards also replace TITOs by carrying win credits on the card from machine to machine and to the cashier or cash machine. This is supposedly the first card like this to be used in the USA.
