Smart Card Reader



Today, smart cards are used in a wide variety of applications from healthcare to personal finance. They are ever-increasing in popularity due to their convenience and security. Generally, smart cards are about the size of a credit card with an embedded IC for storing data.

The Smart Card Reader provides a low-cost solution for reading and writing data to contact memory-based smart cards and is compatible with both the BASIC Stamp and Propeller microcontrollers. Four mounting holes are provided for installation in your application and a card detect switch allows for easy detection of smart card insertion.

Pin Definitions and Ratings

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.

Pin Name Type Function
1 I/O I/O Bidirectional data I/O
2 CD O Detects whether card is inserted
3 CLK I Synchronous clock input
4 RST I Reset
5 VCC P Supply voltage
6 GND G Ground

Pin Type: P = Power, G = Ground, I = Input, O = Output
