What if anything is RFID combined with
If it is RFID chips only, they are preventing counterfeits.
If it is combined with a computer terminal near third base, there is probably an RFID reader under the betting circle. This will record your bets, reduce your comps, give them your high, low and average bets but unless combined with a card tracking system (you should be able to see signs of it) or someone counting down the shoes from the eye, it is of little danger.
