Casinos Bet on RFID-Enabled Gambling Chips

Casinos are becoming more interested in radio frequency identification technology, or RFID, which allows them to track the movement of gambling chips. The device, a chip placed within a chip, communicates to casino operators, through radio frequency, details that include players' average bets. RFID is already being used by Wal-Mart Stores Inc to track product movements from factories to store shelves. The use of RFID on casino chips also helps prevent counterfeiting and theft.
