Invisible mark
Cheating by tampering with a marked deck is almost as old as cards themselves. The only thing that has changed is the technology used to escape detection. Cards marking experience different stages. Throughout the history of card marking so far, the earliest attempt to mark poker involves bending, curling and tiny needle impacts, or scratching with special tools, just like text labels.
As more and more players on the integrity of the brand itself in increasingly high demand, the first process was naturally be abandoned. In second stage, marked poker cards are visible. If scrutinizing the marked deck of cards, you can detect some slight marks without the help of any other cheating devices. It’s very convenient. There are numerous ways to make visible codes on playing decks.
For example, you can use dots in different positions to stand for different numbers. Players have to memorize these patterns. Otherwise, you still don’t know the secret of these cards even though you see the dots.
Later, some minor designs on the back of the card began to appear, marking the recognition by changing the back of the card design by adding or removing lines or bolding the lines of the pattern and changing the color.
Invisible ink marked deck is the most widely used marking cards technology.
As time flies, those marked deck processed by the second stage craftsmanship already can't meet the players demands. Although those cards didn't destroy their shape, but those traditional cards marking have their disadvantage that it must be read closely because the marks are small while luminous and juice marked-card technology can be read closely or from across a table.
Another disadvantage is that visible marks are easily caught by other players if they pay more attention on back pattern. That's why the third stage craftsmanship appeared.

5 types marks for invisible marked deck

That's mean, although those two type cards marked the same way, but you can't use infrared contact lenses or sunglasses to see the marks on playing cards for IR camera lens. There is no doubt that infrared contact lenses will be easier to operate than a camera lens which you need to install into unique item, such as chandelier, surveillance cameras, smoke detector and so on.
Working Principle
Invisible ink marked deck is based on the principle of infrared and ultraviolet light. In our daily life, we are no stranger to infrared and ultraviolet light. We know them, but we can’t see and touch them. They are invisible for us. Invisible ink precisely takes advantage of this principle. Processed cards are “invisible” for us because the invisible ink is beyond the wave band we can see through our naked eyes. Normally, we can see something with wave band between 390 to 700 nm.
If there is something beyond this range, this thing is invisible for us. Actually, it really exists. Just like marked deck poker, there really exist some special marks even though we can’t detect them by our eyes. But if we wear some specific devices, these marks will be visible. When printed by different invisible ink, these cheating cards will have different performances. Because IR invisible ink has different wavelengths with UV ink, IR marked decks can’t be viewed by UV contact lens. So do UV luminous cheating cards.
Q: Can I mark cards with the invisible ink pen?
A: In theory, this is feasible. But how to make the effect of marks is invisible perfectly is not only relaying on the ink, but also our marking cards machine. What's more, you should know how to mix ink with different color according to back pattern of playing cards.
