Abstract
A card with a magnetic stripe when fed into a card reader can be illegally read by a read head unobtrusively attached to the outside of the card reader adjacent to the slot into which the card is fed. To defeat this illegal reading, movement of a card through the read head is interrupted thereby making it difficult for the illegal read head to read the stripe. This interruption occurs at the point where the proper read head inside the card reader is not reading the magnetic stripe. The interruption can be a brief stop or a brief reversal in direction. The interruption occurs once while the card is being fed into the card reader and once when the card is being fed out of the card reader.
