Jack Black Signature

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

Automatic card reading technology has known abuse potential in that it can be used to simplify the practice of brewing preferentially having the dealer reshuffle the cards when 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 see real-time notification to surveillance that a shoe is "hot" to be an important element of the product.

With the card values, decisions of the game, and bet decisions easily accessible, the casino can bet analyze variations, the accuracy of the game, and the change in play.

variation Bet. The easiest way money is made by credit card cons of betting more when he has an advantage. When playing tapes of a recent play session, the software can generate a scatter plot of the amount of the bet against the count at the time the bet was made and find the trendline that best fits the points dispersed. If the player is not counting cards, there will be no trend; bet its variation and variation of account will not always correlated. If the player is counting and paris different depending on the number, there will be a trend whose slope reflects on the average player of this technique.

accuracy of reading. Normal players tend to make mistakes basic strategy. Card counters must know with precision 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 involved.

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