PURPOSE: An extended smart card system and its control method are provided to enable a user to access various data and applications, stored at a large sized storage of a server, by using a smart card. CONSTITUTION: The system comprises a smart card(10), a card reader(12), a host PC(14), and a server(18). The smart card(10) stores card data, e.g. a user ID, a password, and some applets. The card reader(12) reads the card data if the smart card is inserted into a slot. The host PC(14), electrically connected to the card reader(12), stores the read card data at a temporary memory, and transmits the read data to an external system over a network. The server(18) checks an access right by using the transmitted card data, transmits an access permission signal to the host PC(14), and allots a virtual storage for the accessing smart card.
