Mark Milian of the LA Times reports on an iPhone application called A Blackjack Card Counter that has pit bosses in Vegas looking for people who keep their hands in their pockets.
The $3.99 app has a feature, called stealth mode, that allows the user to easily operate the card counter with the phone concealed in a pocket. Simply press the right half of the screen when a card valued at 10 or higher appears on the table or the left half when a low card is flipped. The phone vibrates when it's time to place a big bet. The program also takes additional factors into account that elude most mental card counters and is therefore more accurate.
Using a device to count cards is a felony in Nevada.
