Abstract

The present invention provides an apparatus and method for moving playing cards from a first group of cards into a second group of cards, wherein the second group of cards is randomly arranged or shuffled. The apparatus comprises a card receiver for receiving the first group of cards, a single stack of card-receiving compartments generally adjacent to the card receiver, the stack generally vertically movable, an elevator for moving the stack, a card-moving mechanism between the card receiver and the stack for moving cards one at a time into a selected one of the compartments, another card moving mechanism for moving cards from one of the compartments to a second card receiver and a microprocessor that controls the card-moving mechanisms and the elevator. A count of cards within specified areas of the card handling system is maintained and card handling is halted and all cards counted by adding a count of all cards not within the specified areas to the total of cards counted within the specified areas.
