  • Patent number: 7281656
    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.

  • Patent number: 6527187
    Abstract: A card reader has an opening at the base thereof in communication with the card insertion slot and forward of the IC contacts of the contacts carriage. When foreign materials such as coins are inserted into the card passageway, they are discharged through this bottom opening without contacting or causing damage to electronic contacts and without building up in the reader. Further, a blocking mechanism for the card passageway prevents foreign material such as coins from being inserted. When a read head senses the magnetic swipe of a card as the card is initially inserted, the blocking member is pivoted out of the way.
