DETECTION OF SPURIOUS INFORMATION OR DEFECTS ON PLAYING CARD BACKS

摘要

Methods and systems detect markings or flaws on the backs of playing cards. The method includes: providing ambient radiation at a gaming table and reflecting some of that radiation off a back surface of a playing card; capturing reflected radiation with a radiation sensor; the radiation sensor transmitting signals based on the reflected radiation captured by the radiation sensor; the transmitted signals providing data that contains image data of the back of the playing card; and displaying an image of the back of the playing card based on the image data. The transmitted signals provide image data of the back of the playing card and are also received by a processor that evaluates or compares that data. The system may be an installed casino system (with eye-in-the-sky technology), a portable box, or a component within a shuffling device or dealer shoe.

主权项

1. A method for detecting errors in the back of playing cards comprising:
providing ambient infrared radiation at a gaming table and reflecting at least some of that infrared radiation off a back surface of a playing card; capturing reflected infrared radiation with an infrared radiation sensor; the infrared radiation sensor transmitting signals based on the reflected infrared radiation captured by the infrared radiation sensor; the transmitted signals providing data that contains image data of the back of the playing card; and displaying an image of the back of the playing card based on the image data.
