Abstract: PURPOSE: A method for supplying a gateway service connecting to a web site is provided to make a user use the gateway service to supply a determined cyber money when the user connects to a specific web site. CONSTITUTION: A user of a personal computer(PC) drives a web browser, and connects to a web server of a host. The web server transmits a HTML document including an input widow for inputting identifying information by a user to the web browser. The user inputs the identifying information to the input widow. A membership management program of an application program decides whether the inputted identifying information is normal. If so, the web server transmits a HTML document including an address input window inputting a domain name to the web browser. If the identifying information is abnormal, the user inputs the identifying information again. The user inputs an address of a destination site connecting the address input window. A signal requesting for a connection with the destination site is transmitted to the web server. If the web server receives the signal, the application program increases a balance of cyber money as a determined amount to a membership account database of the user, and stores the increased balance.
