I read the article in IBD today. Think the author was kind of sloppy in his details:

"The firm doesn't make complete betting chips. It sells the RFID tags that casinos affix to the chips they already use. "It's a small RFID tag about the size of the tip of the baby finger that's embedded in the gaming chip," McMeekin said."

Casinos affix to the chips they already use???? I doubt it.

"The RFID chip transmits more than just the amount bet. It also indicates the identity of the player. This way, dealers know if a player is a regular patron and entitled to special prizes or favors. "

Really? I'd like to see the system that can transmit the i.d. of the player that put the chip in play!!!
