Patent Images
1. An IC card system having an IC card and a card terminal used in combination with the IC card, comprising:
- first data storing means for storing data representing the capability of the hardware of the IC card per se;
means for electrically connecting the IC card to the card terminal;
means for sending an initializing signal to the IC card responsive to the insertion of the IC card to the card terminal;
means for sending said data as stored in the IC card to the card terminal, in response to the initializing signal from the card terminal;
second data storing means for storing the data as sent from the IC card in the card terminal; and
means for variably setting the internal operating conditions of the card terminal corresponding to the data stored therein.

Abstract
The data representing the ability and function of the hardware of an IC card as prestored in the IC card is read out from the IC card in response to a reset signal applied from a card terminal. The read out data is stored in the card terminal via a connection terminal. In this card terminal, the operating conditions inside the card terminal are variably set according to the stored data, whereby the compatibility of the IC card with the card terminal is enhanced.

8. Method for initializing an IC card and a card terminal used in combination with the IC card, comprising the steps of:
-
(a) inserting the IC card into the card terminal; (b) electrically connecting said IC card and said card terminal in response to the insertion of said IC card into said card terminal; (c) applying an initializing signal to the IC card to said card terminal upon the completion of said electrical connection for initializing said IC card; (d) sending forth data representing the capability of the hardware of the IC card and stored in said IC card to the card terminal; and (e) storing the sent data in the card terminal received from said IC card for setting an internal operational condition of the card terminal according to the stored data. - View Dependent Claims (9, 10, 11, 12, 13)
