Abstract:
1. An integrated circuit (IC) Card for use with a read/write device, the IC card comprising: a first processing device; a first interconnection defined between the first processing device and the read/write device and including an input/output (I/O) contact pad; a second processing device connectable to the first processing device to communicate with the first processing device via the I/O contact pad; a second interconnection defined between the second processing device and the first processing device; and a switch control to selectively switch between the first interconnection for a transmission of data between the read/write device and the first processing device, and the second interconnection for a transmission of data between the first processing device and the second processing device; communication between the first processing device and the second processing device defining a master slave communication, the first processing device being the master and sending commands to the second processing device, and the second processing device being the slave and returning results to the first processing device.
