<p>PROBLEM TO BE SOLVED: To hold the security of data stored in the memory of an IC card and to collectively manage plural types of data with one IC card. SOLUTION: Plural data storage means 17a-17z store plural types of data for every type of data, and a password data storage means 22 stores password data, which have been set for every data storage means 17a-17z, for example. A collation means collates password data received from outside by input means 12 and 13 with password data and a data processing means accesses the data storage means 17a-17z where matching is obtained with the recognition of matching as a condition. A separation memory 18 stores data of comparatively high secrecy and access from the data processing means to the separation memory 18 is made possible only when an access request from an external reader/ writer where access right to the separation memory 18 is set is given.</p> |
