ABSTRACT:
A transaction system having a first transportable integrated circuit (IC) device, a terminal, and a security device is disclosed. The first IC device includes a processor, memory, data stored in the memory, and an operating program stored in the memory. The terminal includes a reader/writer device, a processor, memory, and an operating program stored in the memory. The reader/writer device establishes communication with the first IC device whereby the processor of the first IC device is in communication with the terminal processor. The security device includes a processor, memory, data stored in the memory and an operating program stored in the memory. The security device communicates with the terminal so that the processor of the security device communicates with the terminal processor. Upon establishing communication with the first IC device, the terminal processor initiates and controls a series of operations by the security device processor utilizing the data and the operating program stored in the security device memory and data received from the first IC device for verification by the security device of the validity of the first IC device.
