An IC card generally consists of a CPU and a writeable or writable and rewritable PROM. Then, an authentication number such as a PIN or card number unique to the IC card is set in advance on the IC card, and when writing or reading, if the authentication numbers input to the IC card do not match, the CPU writes it to the PROM. Or it can be controlled so that reading cannot be performed,
Write or read security is extremely high.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention
While using a card, there is a reading means for reading information electrically stored from an inserted IC card, an input means such as a key for inputting various information, and a RAM, for example, for electrically storing input information. a display means, for example, a liquid crystal display, for displaying the input information from the input means or the read information from the reading means, and electrically storing the input information from the input means in an IC card. Therefore, the writing means allows writing to the IC card only when the authentication signals such as a password or card number from the input means match, and the coincidence of the authentication signals is canceled when the inserted IC card is removed. It is equipped with the following.

Function: It makes it possible to read the information electrically stored on the IC card, but it also allows writing to the IC card only when the authentication signals match, and when the inserted IC card is removed, the authentication signals match. By canceling this, information processing with sufficient security functions can be performed at the site where the data is generated.
