[0002]

2. Description of the Related Art In a computer system using an IC card, the IC card is used for registering and storing data and programs. For example, in the electronic system notebook, the conventional computer of this type has a host computer having one IC card device. Therefore, a plurality of IC cards are required to register / call a large amount of data or programs. Therefore, the user is IC
I had to insert and remove the card.

[0003]

As described above, in the conventional IC card device incorporated in the host computer, the registration / calling of a large amount of data or programs which requires a plurality of IC cards is manually performed by the IC. The card was inserted and removed. As a result, the IC card may be damaged and the reliability thereof may be deteriorated due to an erroneous operation by the user, and the reliability and failure of data, programs, etc. may be deteriorated due to a mistake of the user's IC card. There was a problem in the operation of inserting / removing the IC card when using, and there were major problems in terms of system development.

The present invention has been made in view of the above circumstances, and in a computer system using an IC card, the wireless IC card device communicates with a plurality of IC cards by the communication between the host computer and the wireless IC card device. To store any I from the plurality of IC cards.
An object of the present invention is to provide a wireless IC card device in which a C card is selected to facilitate registration / calling of large-capacity data or the like that requires a plurality of IC cards.

[0005]

In order to achieve the above object, the present invention can connect a wireless communication device to an IC card device incorporated in a conventional host computer and store a plurality of IC cards outside. A smart card expansion device is provided, and a wireless communication device is provided in the smart card expansion device. By wirelessly communicating with the host computer and the smart card expansion device, a plurality of smart cards are not manually inserted or removed by the user. In addition, the user can select an arbitrary IC card and register / call it.

[0006]

Since the wireless IC card device stores a plurality of IC cards and the user can select any IC card from the plurality of IC cards, the user needs a plurality of IC cards. Registration / calling when registering / calling a large amount of user data or application programs becomes easy. Further, it becomes possible to reduce the load of the insertion / removal operation of the IC card, which is a great obstacle to the operability of the user at present. Therefore,
Connecting the wireless IC card device according to the present invention to a host computer, and wirelessly communicating between the wireless IC card device and the host computer;
By storing multiple IC cards in the card device,
The burden on the user of inserting and removing the IC card is reduced,
In addition, the user can easily access the plurality of IC cards.
