Abstract
Card-handling devices may include an input area sized and shaped to receive cards and an output area for outputting at least some of the cards. A defect detection system may be located along a card path downstream from the input area. The defect detection system may include an emitter positioned and oriented to direct radiation toward a major surface of a card as the card moves along the card path. A detector may be positioned and configured to detect the radiation emitted by the emitter and reflected from the major surface of the card as the card moves along the card path. A controller may be operatively connected to the detector and configured to correlate a signal from the detector with an identification of a degree to which the major surface of the card has deviated from a reference plane.
