Do you know how to read a deck of marked cards? This is a good question, but before we reply this question, I have another question: do you know how many types of marked cards there are? This question is related to the marked cards readers closely, if you have answer to this question, so you will know how to read marked cards.
For different types of invisible ink marked cards, you need different marked cards reader to view. There are three types of marked cards: contact lenses marked cards, barcode marked cards for poker analyzer, infrared marked cards.
There is no doubt that the contact lenses marked cards can be seen with invisible ink contact lenses, you also can see them with invisible ink glasses.
While the barcode marked cards, it is still a secret for many people, because the marks of the barcode marked cards are on the four edges of cards, there are still few people know. The barcode marked cards work together with poker analyzer and poker scanning camera together. The barcode of marked cards poker can be read by all types of poker scanning cameras, for example: cell phone camera, wallet poker camera, power bank poker scanner, button scanning camera, water bottle camera and so on.
The IR marked cards are special marked cards, which can't be seen by invisible ink contact lenses, also can't be read by all type of poker scanners. The invisible ink for IR marked cards are different from the invisible ink to mark contact lenses marked cards and barcode marked cards, which are marked with IR invisible ink, the IR invisible ink can't be seen by black light, and which only can be seen by IR Poker Camera.
