ABSTRACT:
In an IC card, a user area is set to have a first area in which a write password is made valid, and a second area in which a read password is made valid. When a write command for the first area is sent together with a password from a read/write apparatus, the password is collated with the write password. When a read command for the second area is sent together with a password, the password is collated with the read password. As a result of the collation, when the passwords are identical, the respective commands are executed.
