Claim:
1. A hand-held device for detecting errors or fraudulent markings on the back of playing cards comprising: a radiation sensor for capturing ambient radiation; the radiation sensor configured to transmit signals based on captured radiation; the transmitted signals providing data that contains image data of the captured radiation with both visible wavelength radiation and radiation outside the visible wavelengths; a processor configured to receive the transmitted signals as both visible wavelength radiation and radiation outside the visible wavelengths, process the transmitted signals both visible wavelength radiation and radiation outside the visible wavelengths and transmit the processed transmitted signals in a format that can be displayed as a visible image on a display system combining the processed transmitted data into the visible image; and the display system configured to display the visible image of a surface from which both visible radiation and radiation outside the visible wavelengths were reflected off or transmitted through to provide the transmitted signals; wherein a cut-off filter allowing transmission of radiation outside of the visible spectrum is positioned between the radiation sensor and the back of a playing card.
