First Claim
1. A mobile electronic apparatus which performs a process according to a command given by an external apparatus, comprising:
- a storage unit which stores a record file which stores a plurality of record data;
a data saving process unit which stores record data before rewriting of the record data requested to be rewritten in the record file as backup data, in the case where a command requesting the record data in the record file to be rewritten is given from the external apparatus; and

Abstract
A data memory of an IC card serving as a mobile electronic apparatus stores a record file which stores record data. The data memory has a record area which stores the record data and a data saving area which stores backup data to the record data stored in the record area. When a CPU of the IC card receives a command which requests record data in the record file to be rewritten from an IC card processing apparatus through a communication control unit and an interface, the CPU stores the record data stored in the record area as backup data in the data saving area. The CPU of the IC card rewrites the record data stored in the record area after the backup data is stored in the data saving area.
