ABSTRACT:
An IC card processing apparatus has a data reading/writing unit which accepts an IC card and electrically connects the IC card with terminal equipment. Data is exchanged with the IC card and/or the data reading/writing unit. To shorten the time for processing data of the IC card processing apparatus, the terminal equipment directly exchanges data with the IC card. To achieve this, the data line of the terminal equipment is connected to the data line of the IC card. Before using the IC card for transactions, the data reading/writing unit feeds a personal identification number (PIN) to the IC card for identifying the PIN information. To prevent the PIN information from being delivered to the terminal equipment, a switch is provided between the data line of the terminal equipment and the data line of the IC card. While identification of the PIN information is underway, the switch remains totally open, preventing reception of the code by an unauthorized party.
