SERVICE PROVIDING SYSTEM, SERVICE USING DEVICE, TEMPLATE TRANSMITTER

摘要

Transmitted from a first-time template transmitter (20) provided in a service providing device (100) to a service using terminal (10) is a first-time template including address information representing the address to which data used for the authentication is transmitted from the service using terminal (10), user input assisting information for displaying the interface used when the service user inputs data into the service using terminal (10), and authentication basic information. The service using terminal (10) receives user input data inputted according to the user input assisting information, processes the authentication basic information included in the first-time template and the authentication information included in the user input data to transmission data, and transmits the processed data to the address indicated in the first-time template address information. With this in such a service providing system comprising a service using terminal (10) and a service providing device (100) for providing a service to the service using device (10), the number of communication processings required for service user can be reduced.
