Barcode marked cards are a special type of playing cards that have a barcode printed on them. These barcodes can be scanned and interpreted by specialized reading devices to reveal the value of the card. They are mainly used in games of chance, such as poker, blackjack, and baccarat, as well as in magic tricks and illusions.
The use of barcode marked cards dates back to the late 20th century, when they were first introduced as a way to improve the accuracy and speed of card counting in casinos. This made it easier for skilled players to keep track of the cards that had been played, giving them a better chance of predicting the outcome of the game.
However, the use of barcode marked cards has since spread beyond the casino world, and today they are also used by magicians and performers to create illusions and magic tricks. The barcodes can be easily disguised and blended into the design of the card, making them virtually undetectable to the naked eye.
One of the main advantages of barcode marked cards is that they allow for quick and accurate readings of the cards. This makes it possible for players to keep track of the cards that have been played in real-time, without having to rely on memory or other methods. This can greatly improve a player’s chances of winning, especially in games where strategy and card counting are important factors.
Another advantage of barcode marked cards is that they can be used with specialized reading devices, such as barcode scanners, which are designed specifically to detect and interpret the barcodes on the cards. These reading devices can quickly and accurately identify the value of each card, making it easier for players to keep track of the cards that have been played.
However, it’s important to note that the use of barcode marked cards is not without controversy.

This is because marked cards can give players an unfair advantage, which can negatively impact the integrity of the game.
Despite these controversies, barcode marked cards remain popular among players and magicians alike. They offer a unique and convenient way to keep track of the cards that have been played, making them an indispensable tool in the world of gaming and gambling.
