IC card processing apparatus
First Claim
1. An IC card processing apparatus for selective connection and data communication with an IC card, comprising:
- insert means for receiving the IC card and electrically connecting with the IC card;
read/write means, coupled to said insert means, for transmitting data for the IC card to the insert means, including PIN supplying means for supplying PIN data corresponding to a predetermined security code;
input means, coupled to the read/write means, for inputting transaction data for the IC card to the insert means, corresponding to specific transactions to be processed; and
switch means, electrically coupled to and interposed between the input means and the insert means, for interrupting an electrical connection between the input means and the insert means during transmission of the PIN data from the read/write means to the insert means.

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.
