Akiba over at Freak Labs has found an interesting article on how RFID is being used to track a players chips and even cards.
These days in Vegas, even the cards can tell tales — and talk to the tables. Ask the armed motorcyclist who stole $1.5 million in chips from a Las Vegas casino. He’ll have trouble cashing out because the chips, some worth $25,000 apiece, were embedded with radio frequency identification (RFID) tags.

Thief should:
a) send an accomplice to buy more RFID tagged chips from the casino
b) microwave them, distroying the RFID
c) send accomplice back to cash out those chips. If they accept them despite the RFID tags inside not working then it would probably be safe to do the same with some of the stolen chips.
