I watched a Roulette game at Yaamava' yessterday'. They were using the house Abbiati chips, mostly $1 and $5 denominations, although $25 bets were happily accepted. I cannot see how the "black eyed" $1 chips could be tracked by radio device, although they were tossed down the hole and came back sorted out properly. Perhaps the device works by UV light? I then tried to get into the Buffet line, and asked a casino employee if I could eat there. "Do you have a reservation?" he asked. "No," I replied, "But the Indians do!" And that's about the time I was kicked out of there.
