Protec Fire Detection

Several automated systems have been designed to facilitate the detection of card counters. Mind game system scans card values for the entire deck after shuffling just prior to playing. Shuffle Master Intelligent Shoe system scans card values individually as cards exit the shoe. Software called Bloodhound and Protec allows voice input values of the cards and betting, which is used to determine the player edge. A more recent innovation is the use of signatures embedded RFID in casino chips to the table can automatically track paris.

Automated card reading technology has known abuse potential in that it can be used to simplify the practice of preferential mixing-have the dealer reshuffle the cards whenever the odds favor the players. To avoid liability issues, some blackjack protection systems were designed to avoid sending data over the network until the shoe is completed. Other vendors consider the real-time notification to surveillance that a shoe is "hot" to be an important product feature.

With the card values, the decisions of the game, and bet decisions easily accessible, the casino can bet analyze variations, the accuracy of game playing and variation.

Bet variation. The easiest way to a map-cons make money is to bet more when he has an advantage. When playing tapes of a recent game session, the software can generate a scatter plot of the amount wagered against the count at the time the bet was made and find the trendline that best fits the scattered points. If the player is not counting cards, there will be no trend; bet its variation and change account will not always correlated. If the player is counting and varying according to the number paris, there will be a trend whose slope reflects the average player's edge of this technique.

Play precision. Normal players tend to make mistakes-base strategy. Card counters must accurately know exactly when to hit, stand, split or double. The software can check the speed at which the player makes errors and calculate the house edge that results.

Play variation. When the card-counters vary from basic strategy, they do so in response to the count, to gain an additional advantage. The software can check if there is a tendency to play variation. It is particularly interesting if the player sometimes (when the count is positive) takes insurance and stands on 16 against a dealer 10, but plays differently when the number is negative.
