I don't think the RFID played so much a part in this guy getting caught as the article implies. He was caught trying to sell them online as the "Biker Bandit." The primary $25K chips were pulled and the back up chips were put into play immediately. He managed to play the $5K and lesser chips he stole while staying at the casino.

He got sentenced to more time for the Suncoast robbery of $20K than the Bellagio $1.5M!
