The Arduino SMARTSHIELD connects your Arduino with smartcards. This allows the implementation of electronic payment systems and access control.
The Arduino shield SMARTSHIELD has two smartcard connectors: a standard ISO-7816 and a SIM that can be used for mounting a SAM module for authentication that allows to easily implement cryptographic functionality.
A microcontroller generates the necessary signals for the proper functioning of smartcards and interfaces Arduino via the SPI port. To allow compatibility with other commercial shield, you can configure the address of SS pin using a jumper (pin 7/8/10).
On the shield are two diagnostic LEDs that provide information about smartcards presence and exchange data.
The SMARTSHIELD shield interfaces with Arduino via SPI pins 7/8/10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). Hardware compatibility of SMARTSHIELD is guaranteed with Arduino Uno e Duemilanove. For different models of Arduino you can still use the SMARTSHIELD using the software library SPI.
Synchronous Smartcard Library
This library allows an Arduino board to control synchronous smartcards (SLE4442 and SLE4428 protected memory cards) by SMARTSHIELD shield.
CPU Smartcard Library
This library allows an Arduino board to control asynchronous (CPU) smartcards with T=0 protocol (i.e. ACS ACOS, SCHUMBLERGER PAYFLEX) and T=1 protocol (i.e. SIEMENS INFINEON, ST INCARD) by SMARTSHIELD shield. It is also supported the italian national and regional services card (CNS/CRS).
