Abstract
Provided is an IC card capable of downloading a card manager even after issuance of the IC card. A first card manager stored in the ROM of an IC card is made to be capable of downloading a privileged application, which is an application having a privilege, and a privileged API in the ROM is made accessible from the downloaded privileged application. When the privileged application accesses the privileged API, the privileged application can operate as the card manager, so that the IC card can download a card manager even after issuance of the IC card.
