Marked Poker Cards

Marked decks have a long history. At the beginning of card marking, practices were simple and crude – even outright foolish. For example, players would make a marked deck by bending the cards or add visible marks on the back with a needle or nails. They would even add or remove lines and patterns from the back of the card design.

Not many people will notice such a small change in the color or pattern on poker cheat cards – even a cheater won’t find such markings easily at first. But if you look at them from a short distance, these kinds of marked cards are easy to detect. Another fatal flaw is that they must be read close-up. Once luminous ink and juice ink arrived on the scene to make invisible marks, it proved a real breakthrough in the creation of poker cheat cards.
