Abstract
A method of reading suit and rank of playing cards is enabled on a system for controlled provision of image content of faces of a playing card that has: e) a support surface for playing cards; f) a source of infrared radiation; g) an infrared sensitive camera; and h) a processor. The infrared sensitive camera positioned to capture infrared radiation transmitted through the playing cards and transmit information based on the captured radiation to the processor; and the processor configured to provide suit and rank information of a playing card through which the infrared radiation was transmitted.

A method of reading information from a playing card while an image face of the playing card is hidden by a visible light-opaque back comprising:
- an infrared-sensitive camera positioned over the playing card back receives infrared information passing through the playing card;
- a filter on the camera filtering out at least some visible and some infrared radiation, allowing a defined range of infrared radiation into the camera;
- the camera capturing radiation within the defined range of radiation and transmitting signals based on the captured radiation;
- a processor receiving the transmitted signals and executing code to define patterns in the captured radiation;
- and
- the defined patterns including image content of suit and rank on the image face of the playing card.
A system for controlled provision of image content of faces of a playing card comprising:
- a) a support surface for playing cards;
- b) a source of infrared radiation;
- c) an infrared sensitive camera;
- and
- d) a processor;
- the infrared sensitive camera positioned to capture infrared radiation transmitted through the playing cards and transmit information based on the captured radiation to the processor;
- and
- the processor configured to provide suit and rank information of a playing card through which the infrared radiation was transmitted.
