PLAYING CARD HANDLING DEVICES, SYSTEMS, AND METHODS FOR VERIFYING SETS OF CARDS
First Claim
1. A system for handling and verifying sets of playing cards, the system comprising:
- an automatic card shuffler, comprising;
a card-shuffling mechanism configured to shuffle a set of playing cards; and
a printing device for applying a same set symbol to each card in the set of playing cards to uniquely identify the set of playing cards prior to removal of the set of playing cards from the automatic card shuffler;
a card output tray comprising;
a receptacle for receiving playing cards from the set of playing cards in the automatic card shuffler; and
a set symbol reader for reading each card of the set of playing cards for a presence and identity of a set symbol; and
at least one processor programmed to randomly select the set symbol for application to each card in the set of playing cards by the printing device and configured to verify, using data from the set symbol reader, that each playing card of the set of playing cards includes a set symbol matching the randomly selected set symbol.

Abstract
Systems include an automatic card shuffler and a shoe. The automatic card shuffler may include a printing device for applying a randomly selected set symbol on each card of a set of cards. The shoe may include a set symbol reader for reading each card for a presence and identity of a set symbol. A shoe processor may be configured to receive a signal from a shuffler processor indicating the selected set symbol to enable the shoe processor to verify that each card belongs to the set of cards. An automatic card shuffler includes a processor programmed to randomly select a card set symbol and a card-marking system for forming the randomly selected set symbol on cards. Methods include forming a randomly determined set symbol on each card of a set of cards and detecting whether cards include a set symbol matching the determined set symbol.

9. A method of verifying that playing cards to be removed from a card-handling device belong to a particular set of playing cards, the method comprising:
-
inserting the particular set of playing cards into a first card-handling device comprising a printing device and a card-moving mechanism; randomly determining a set symbol to be formed on each card in the particular set of playing cards with at least one processor; forming the same randomly determined set symbol on each card in the particular set of playing cards with the printing device of the first card-handling device to uniquely identify the set of playing cards; moving the particular set of playing cards from the first card-handling device to a second card-handling device; detecting with a card reader of the second card-handling device the presence and identity of a set symbol on each card therein; and verifying, with the at least one processor and using data from the card reader of the second card-handling device, whether each card in the second card-handling device includes a set symbol matching the randomly determined set symbol. - View Dependent Claims (10, 11, 12, 13, 14)

15. An automatic card shuffler, comprising:
-
a card infeed tray configured to receive a set of playing cards to be shuffled; a card-shuffling mechanism configured to receive and randomize the order of cards from the set of playing cards in the card infeed tray; a card output tray configured to receive playing cards from the card-shuffling mechanism; at least one processor programmed to randomly select a set symbol to form on each card in the set of playing cards; and a card-marking system for forming, prior to delivery of each card to the card output tray, the same randomly selected set symbol on each card received in the card infeed tray. - View Dependent Claims (16, 17, 18, 19, 20)
