Smart Card Reader ( 32320) v1.0 7/15/2010 Page 1 of 2 How it Works The pins of the IC embedded in the smart card are accessed through the gold contact pads on the top of the card. The Smart Card Reader makes this connection through eight contacts inside of the reader module (card should be inserted with the gold pads down). Once connected, the pins of the smart card broken out into breadboard friendly 0.1 spacing.
