Abstract
PURPOSE:To reduce software-like load by making the check bit of an incoming first transmission block forcedly into an error representing level, and informing difference or sameness from/to the contents of the sequentially incoming second transmission block. CONSTITUTION:An I/O 16, that is, an interface to an IC card supplies a power source voltage Vcc to the IC card, and at the same time, inputs a reset signal, a clock signal and data, etc. A shift register 10 fetches the data transmitted from the IC card to a microcomputer 15, and inputs it to a setter 11. The setter 11 inputs the data, as it is or after inverting it, to an AND circuit 12, and a signal generation circuit 13 makes the check bit of the first transmission block forcedly into the error representing level. The computer 15 compares the contents of the first transmission block with the contents of the sequentially incoming second transmission block, and lights an OK lamp 3 or an NG lamp 4. Thus, the IC card can be tested while the software-like load being lightened.
