20. An automatic deck verification system comprising:
-
a microprocessor with memory for controlling the operation of the device;
an in-feed compartment for receiving cards to be randomized;
a card moving mechanism for moving cards individually from the in-feed compartment into a card reading compartment;
an image capture system that can identify at least the rank of each card as it is moved into or through the card reading compartment, but before removal from the device, the image capture device illuminating a face of the card displaying the rank and suit with electromagnetic radiation selected from the group consisting of ultraviolet radiation, near infrared radiation, infrared radiation, far infrared radiation, and wavelengths comprising a fluence consisting of at least 40% wavelengths selected from the group consisting of 1) UV, Violet, Indigo, blue-green, green, and infrared;
2) UV, blue-green, green and IR (as described above);
3) UV, blue green and green;
4) UV and green; and
5) green;
the microprocessor identifying a position for each card in each set of cards formed in the card mixing compartment, a memory that records at least the rank of each card in each set of cards read in the card reading compartment.
