Abstract
A portable terminal in which an application area in a contactless IC chip can be shared by a plurality of users. The portable terminal is provided with the IC chip that has a contactless communication function enabling use of a plurality of services. In addition, the portable terminal is provided with an application area information storage unit that stores application area information for associating users, application identifiers for identifying applications corresponding to services to be used, and plural application areas provided in the IC chip; and an application area control unit that puts into a useable state an application area of a user corresponding to the identification information in the IC chip, based on the application area information and the identification information for identifying the users, read from a loaded storage medium; wherein the plurality of services that use the contactless communication function can be used by each user.

9. An application area control method of performing control of usage of a plurality of application areas provided in an IC chip of a portable terminal in which said IC chip, having a contactless communication function, is mounted, and which enables services using said contactless communication function, wherein said application area control method comprises:
-
storing application area information associating users, application identifiers for identifying applications corresponding to services to be used, and plural application areas provided in an IC chip, in an application area information storage unit provided in a portable terminal; and in a case where a storage medium that stores identification information for identifying users is replaced, putting into a usable state an application area of a user corresponding to said identification information in said IC chip, based on said application area information and identification information read from said storage medium.

10. An application area control program that performs control of usage of a plurality of application areas provided in an IC chip of a portable terminal in which said IC chip, having a contactless communication function, is mounted, and which enables services using said contactless communication function, wherein said application area control program executes on a computer installed in said portable terminal:
-
a process, in a case where an application identifier is inputted from outside, of storing application area information for associating users, application identifiers for identifying applications corresponding to services to be used, and plural application areas provided in an IC chip, in an application area information storage unit provided in a portable terminal; and a process, in a case where a storage medium that stores identification information for identifying users is replaced, of putting into a usable state an application area of a user corresponding to said identification information in said IC chip, based on said application area information and identification information read from said storage medium.
