SERVICE PROVIDING SYSTEM, SERVICE USING DEVICE, TEMPLATE TRANSMITTER

摘要

A first-time template transmitting device (20) in a service providing device (100) transmits to a service using terminal (10) a first-time template which contains: transmission destination information indicating a transmission destination to which the service using terminal (10) transmits data for authentication; user input assisting information based on which an interface for use by a service user entering data to the service using terminal (10) is displayed; and basic authentication information. The service using terminal (10) receives user input data entered on the basis of the user input assisting information, converts the basic authentication information contained in the first-time template and authentication information contained in the user input data to transmission data, and transmits the converted data to the transmission destination indicated in the transmission destination information in the first-time template. These actions reduce the number of communication process steps required to use the services in a service providing system including the service using terminal (10) and the service providing device (100) which provides services to the service using terminal (10).
