There are many people who claim that they live lives above reproach. They are God-fearing, appear honest and are quick to let others know when they go off the straight and thin. Even those who claim to be “honest” are cheaters. They may not have stolen an entire recipe, but they did something extra to get a leg up in a competition.
Over the years, casinos have been able to keep a tight lid on card marking. Due to the reduction in floor supervisors, and the lessening of management’s emphasis on game safety, cheaters are now able to mark more cards.
Marking cards involves putting invisible ink, which is not visible to others, including the dealer. There are a variety of ways to mark a card, and they all work differently depending on what type of mark is required. Some of the traditional methods include card bending and chip indentations. The newest high-tech methods use juice dust and other chemicals to mark a card, which are then invisible to the naked eye but visible through special lenses like IR contact lenses or perspective sunglasses.
Even the most sophisticated ways to mark a card are still considered cheating. Why? It is because it breaks the game rules and gives a cheater an unfair edge. So, if you’re going to try to mark a card with invisible ink to cheat in a game, be careful — it might not be worth the risk.
