This is a breakout board for our SMD Smart Card socket. Smart Cards are plastic cards with an embedded chip used to store any data you want. Smart Card applications are limitless; and they're growing increasingly popular, showing up on credit cards and other common identification cards.
A standard credit-card sized plastic card (53.98mm width) should fit snugly into the onboard socket. The socket forms a physical connection with the eight contacts on a Smart Card. See the schematic and datasheet below for pin-out.
All pins of the Smart Card socket are broken out to a 0.1" pitch header.
