Claim Text:
1. A method for detecting errors in the back of playing cards within a housed system having two inner side surfaces, an inner back surface, an inner top surface, an inner bottom surface and an open front area through which playing cards may be manually placed and removed, the method comprising: placing a playing card through the front area face-down onto the inner bottom surface of the housed system; providing ambient infrared radiation from the inner top surface of the housed system and reflecting at least some of that infrared radiation off a back surface of a playing card to an infrared radiation sensor at the inner top surface within the housed system; capturing reflected infrared radiation with the infrared radiation sensor at the inner top surface within the housed system; 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 actual image of the back of the playing card that includes erroneous markings or fraudulently applied markings indicating at least rank of the playing card based on the fraudulently applied markings within the image data.
