Abstract

In a portable terminal 10 incorporating a non-contact IC 20, the non-contact IC 20 includes a card appli storage region 24 in which a card appli is stored, and the portable terminal 10 includes an appli storage region 15 in which appli's inclusive of the card appli are stored. When the non-contact IC 20 executes non-contact communication with an external R/W 30 to store the card appli selected by the external R/W 30 in the card appli storage region, a storage region for the card appli is ensured in such a manner that the card appli already stored in the appli storage region 24 is saved into the appli storage region 15. The saving of the card appli stored in the card appli storage region 24 of the non-contact IC 20 is executed using a trilateral communicating function.
