A pair of fashionable home game perspective sunglasses can be turned into a cheating device for poker by electroplating purple membranes on the lenses. The lenses can reflect and transmit infrared light to allow a player to see the values and suits of the cards without occlusion. These glasses can be used in both professional and home tournaments. The perspective sunglasses, unlike contact lenses, can be worn as much as you like.
They can also be easily hidden in other sunglasses to ensure that you are not detected when wearing them. It also comes with a high-quality invisible ink marker that can be written on the card, making it easy to use. The invisible ink is made from a sensitive material which can be read even when hidden by the glasses. The glasses are also a good choice for reading luminous marks on the back of a playing card.
The present invention can be used in any shuffling systems that use physical cards, but especially with mechanical shoe shufflers. The present invention can also be used at intermediate positions between the input areas for cards and the delivery trays, to read the cards as they are being moved by electromagnetic components. To detect certain forms or tamperings, polarized light can be used. Alternatively, the polarity of light source can be rotated to create a moving light. This method can work with a wide variety of standard playing cards that are available commercially.
