Some people use a poker card cheating gadget to increase their chances of winning a game. The device scans bar codes on cards to provide information about their ranking and suit. It can also tell the player what hand he will win. The device is usually hidden in a battery, watch, or other item which can be easily hidden at a table. It can be disguised even as a ring.
A shiner is another popular poker cheating gadget. The shiner is a mirror or other object that will reflect the indexes of the cards. This allows you to read the cards without anyone else knowing. The shiner is anything that can be easily concealed at a table of poker, such as a lighter.
A skilled cheat may also use a technique known as false dealing. Card sharps will often deal themselves a desired card. This card is usually the card at the bottom of the deck or a particular card in the center. This can be done with or without a confederate.
The CVK 500 poker analyzer, which looks and functions like a normal phone, has an internal scanning camera. The poker scanner can be used to scan the barcodes hidden on marked playing cards. It can be attached to a phone or inserted into a deck of cards.
