ABSTRACT:
A portable terminal including a noncontact IC card function unit and capable of being used by inserting a subscriber information card is provided, in which a noncontact IC card use permission list on which numbers of subscribers permitted to use a noncontact IC card function are registered is prepared in advance; the subscriber number recorded on the subscriber information card is compared with the noncontact IC card use permission list to judge whether or not the relevant subscriber number is in the list, and if the relevant subscriber number is not included in the list, only the function of noncontact IC card function unit is stopped. Accordingly an arbitrary third party is prevented from using the noncontact IC card function in a portable terminal incorporating a noncontact IC card function and capable of being used by inserting a subscriber information card such as an SIM card.
