Abstract: A communication control function for prohibiting communication with card programs due to other terminal applications while a certain terminal application is communicating with its corresponding card program is assigned by the present invention to the IFD driver, which controls communication with an IC card, in an IC card terminal. This enables an IC card terminal to process commands from a plurality of terminal applications without causing an error to occur.

Abstract: A multi-application type IC card that can be accessed by an external terminal of a file system type IC card. There are installed, on a multi-application type IC card, emulator programs that can process commands from an external terminal for a file system type IC card. This will enable an external terminal for a file system type IC card to access a multi-application type IC card.

Abstract: When a user accesses an advertisement on an on-line advertising system from a user terminal on the Internet using a WWW browser, an advertisement including the toll-free telephone number of a store is sent to the user terminal. When the user calls this toll-free telephone number, a toll-free call control system connects that call from the user to the store and, at the same time, obtains information on that access to the toll-free telephone number as log information. This log information is posted to the service provider, and the service provider analyzes the hit rate from this log information and the WWW browser access log. From this result, the on-line service provider or the advertiser can determine the effectiveness of that advertisement.

Abstract: Trigger information that specifies locations where HTML text is to be changed is held in a WWW Server. Shell script that changes the HTML text is started up at fixed time intervals and rewrites the file names on the line after the trigger that specifies information such as the home page background image, the in-line image, text and audio information. In this way, the home page can be changed efficiently and flexibly at fixed time intervals.
