1. A feed system for feeding playing cards into a card handling system comprising:
- a playing card input compartment having a playing card support surface, a front wall, a rear wall and two side walls;
the playing card support surface having a slope towards the front wall of between 12 and 22 degrees;
the front wall having a slot that allows single playing cards to pass from the support surface through the slot into the card handling system;
a playing card moving system associated with the playing card input compartment that advances single playing cards through the slot;
wherein playing cards are pressed against the playing card moving system by gravity and without other mechanical pressure wherein an extendable and retractable barrier is present in the vicinity of the slot to either prevent or allow, respectively, playing cards to pass through the slot.

9. A method of advancing playing cards from a single playing card input compartment to a card moving system that transports cards from only the single playing card input compartment into a card rearranging zone selected from the group consisting of playing card shuffling and playing card sorting zone, the method comprising:
- providing only a single playing card input compartment and a playing card rearranging zone, and placing a set of cards into the compartment so that a bottom card of the set lies supported at a bottom of the compartment at a slope of 12 to 20 degrees from horizontal, wherein playing cards are pressed against the bottom of the compartment by gravity and without other mechanical pressure, and cards are subsequently advanced mechanically through a slot out of the input compartment and into direct contact with at least one pair of nip rollers in the card rearranging zone.
