Abstract
With a portable compact flash card retaining application software/database set in a portable terminal, the portable terminal performs data processing by accessing the application software/database in the CF card. First, the portable terminal reads terminal ID previously stored in the CF card. Then, the portable terminal compares the terminal ID in the CF card with its own terminal ID previously set, and determines whether or not to be able to access the application software/database in the CF card based on the comparison result.
