Abstract: Card processing mechanisms and methods whereby after a card has been processed on one surface thereof at a card processing station such as, but not limited to, a card printing mechanism, the card can be recirculated back upstream of the card processing station along a return card travel path that is separate from the primary card travel path through the card processing station where the card can then be reintroduced back into the primary card travel path and transported through the card processing station a second time. As the card is being returned along the return card travel path, the card can be flipped over so that when the card is transported back through the card processing station, the opposite surface of the card can be processed.
