Playing card handling devices, systems, and methods for verifying sets of cards

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, a card-moving mechanism, and a random number generator;
• randomly determining a set symbol to be formed on each card in the particular set of playing cards with the random number generator of the first card-handling device;
• 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;
• transmitting with a data transmission device of the first card-handling device a signal representing the randomly determined set symbol to the second card-handling device;
• and
• detecting with the second card-handling device whether each card therein includes a set symbol matching the randomly determined set symbol transmitted from the first card-handling device to the second card-handling device.

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 shuffled playing cards from the card-shuffling mechanism;
• a 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.
