Phuong Quoc Truong aks Pai Gow John plead guilty in casino scam:
According to federal prosecutors, the scheme worked like this: A member of the crew, called the card recorder, would track the order of blackjack cards, relaying them with a hidden transmitter to an off-site associate who would enter the sequence into a computer.
The bribed dealers would then perform false shuffles, creating a “slug” of unshuffled cards. The slug would be returned to the shoe, the device that holds the cards being dealt. When the slug cards were dealt in later rounds, the card recorder would signal associates at the table to dramatically increase their bets on hands the recorder knew would probably win. The off-site associate, using a card-tracking computer program, would relay when the odds were the greatest.
