Cheating at a poker game can ruin your reputation. There are ways to cheat and win poker without breaking any laws. These include using marked cards, which have hidden marks that you can only see with special equipment. These marks can reveal to you the suit or the number of the card before the dealer deals. This can help you decide whether to call a bluff, or fold your hands.
The most popular method of cheating at poker is using invisible ink marked playing cards. These cards have a message printed on the back that our human eyes cannot see, but which can be seen by contact lenses or infrared sunglasses. This can help you see the cards that your opponents have before they are dealt and decide when to bet.
A wireless camera is another common cheating device. These devices can be difficult to detect because they are small and compact. They can be hidden inside a watch, car key or other small items. They can communicate to the cheater via a small speaker and audio earpiece.
You can also purchase a poker analyzer/scanner that can read the barcodes on both sides of a card. This device will then send this information to your mobile phone or tablet, which you can then use to analyze the results of the hand. This can give a huge advantage over your opponents. However, the person running the games may be aware of this.
