The Caesars Entertainment chain of casino resorts has brought the MindPlay technology to its games.

Using miniature built-in sensors, they can track both the cards being played and betting chips � giving the house a more accurate way of rewarding big players with “comps,” and weeding out card counters.

Caesars Chief Information Officer Carol explains: “Pride MindPlay tracks cards and chips. The dealer shuffles cards. … On the side of the card, there’s invisible ink, and each card is bar coded. The system reads the stack of cards and knows when the cards are being dealt out, and which card goes to which player. The chips have a stripe on the side of them, and there are computers under each table that can read the side of the chip.

With the information we get, we know how many hands are being played, the value and size of someone’s bet as they play. We use that information to rate the player for comps.”
