Recently a poker card was taken from a major casino where suspected cheating was going on. The card was determined to be synthesized in such a way that a card could be switched from one face value to another using high tech equipment. This card was chosen at random so the other cards in play were capable of this as well.
Casino technology development companies have patented this idea for several years. Now proof has been discovered that they are actually in play.
Bally Technology - Articles & Methods to facilitate the delivery of Playing Cards. Patent # 11480345
I'll just post a piece from the patent here:
"In still other embodiments, the playing card media may take the form of existing playing cards, from which the playing card value markings will be erased, prior to being reformed or otherwise generated. In some embodiments, the playing card media may take the form of a fiber based media, for example card stock, vellum, or polymer based media. In some embodiments, the playing card media takes the form of an active media, for example a form of electronic or "e-paper", smart paper, and/or ink code, which allows the formation and erasure of markings via electrical, magnetic, or electromagnetic radiation.
Smart paper is a product developed by Xerox Palo Alto Research Center, of Palo Alto, Calif. The smart paper consists of a flexible polymer containing millions of small balls and electronic circuitry. Each ball has a portion of a first color and a portion of a second color, each portion having an opposite charge from the other portion. Applying a charge causes the balls to rotate within the polymer structure, to display either the first or the second color. Charges can be selectively applied to form different ones or groups of the balls to from the respective markings 154-160 on the playing cards 108. The markings 154-160 remain visible until another charge is applied. Alternatively, the playing card handling system 120c can be adapted to employ color-changing inks such as thermochromatic inks (e.g., liquid crystal, leucodyes) which change color in response to temperature fluctuations, and photochromatic inks that respond to variations in UV light"
A patent that uses a random number generator to deliver physical playing cards, HMMMM
The card found was synthesized using a type of bichromal molecules such as chiral nematic liquid crystal molecules & made into thin film dye layers which are transparent or invisible until a certain wavelength of electromagnetic radiation is aborbed by the card. This happens in femoseconds as soon as the card is exposed to light.
