Camera Ink Demo
This demo shows one of the possible methods of marking cards for a camera system. The ink used in this demo is very similar to the ink that was used to mark the cards in the Camera System and the Gaffed Blackjack Shoe demos. However, this ink is different.
As you can see from the video, the ink used in this demo appears much darker then the ink in the other two demos. Without revealing the exact specifications of this ink it suffices to say that this ink fluoresces at a different wavelength then the inks used in the other demos. As a result, the ink marks appear much darker on camera.
This demo shows an example how cards may be marked to cheat at poker; i.e. marked for value and suit. The marks are pretty obvious, should they be discovered. However, this ink does not have to be used exactly as shown in this demo.
Since this ink is capable of producing marks that appear almost black on camera the marks can be much more discrete. For this, one would need to know a secret code that has (to the best of my knowledge) been developed specially for the game of Texas Hold'em. Best I can describe without revealing the secret, the code is comprised of lines that appear at the outer frame of the cards (on the back, of course). The particular position and orientation of the marks give away the value and suit of each and every card and also yields some other advantages that I cannot discuss at this time. But basically, it boils down to the marks being less obvious (not that anyone could see them without a camera, anyway) and also more practical, specifically to cheat at Texas Hold'em.
There are other marking possibilities, however.
If the cards are marked to cheat at blackjack there is no need to maker any other cards then the 10-value cards. In this case all the 10-value cards can be marked in less then 10 seconds. Basically, the 10s, Js, Qs and Ks are removed from the deck, spread across a flat surface and one stroke of a brush will edge-mark all 16 cards. The process is then repeated for the opposite side. These edge marks can be used to locate all the 10-value cards inside the shoe. The edge of the top card is visible at the bottom of the slot and (depending on the design of the shoe) the edge marks are visible across the entire shoe, due to the fact that the cards are naturally beveled when they lay inside of a dealing shoe. Of course, there is also always a possibility to use a gaffed shoe (gaffed in a number of ways, specifically for this scam).
I am often asked the question, how invisible is this ink? Since I am a bit exhausted form answering the same question, over and over again, I might as well explain it here.
Of course, there is no such thing as a truly invisible substance. When I look inside the ink vial, I can tell there's ink inside. So, the ink is not literally invisible. If that vial was filled with some kind of ink that was truly invisible, the vial would look empty, even when there's ink inside. So, the ink is not literally invisible. In fact, it is quite dark.
So, the ink is invisible just form a practical sense. If you examine the cards with your naked eyes, you will not see any ink marks. But as soon as you view the same cards through the cameras system, the ink marks will look exactly was you see them on this video. Furthermore, the particular ink used in this video is also not visible with any kind of luminous glasses or contact lenses. You need a camera to see these marks.
Now, since the ink is not literally invisible, it can be visible, even without a camera, if the ink is applied too thick. In this case, the ink would appear pitch black on camera and would only have a faint appearance to the naked eye.
All camera systems have not been created equal. A primitive camera system would basically be a camera version of a luminous system. Some luminous systems are very good, so we could expect to make an equally good camera system, using the same technology. However, those camera systems are obviously not as good as this one, since the same marks can be seen with luminous glasses or contact lenses.
And lastly, the primitive (or should we call them "luminous") camera systems would only work for red-backed cards, due to the fact that they work on the principle of color blocking. However, this camera system works on any cards, of any colored backs. The cards used in this particular video were blue. But they could just as well have been red, green or any other color. It should be noted, however, that all cards do not produce the same results.
