Content use system, information terminal, and settlement system

摘要

Provided is a new system for content use and settlement. A user requests a mobile telephone charge management server ( 3000 ) to perform proxy settlement for goods purchased using mobile telephones 1 ( 4100 ), 2 ( 4200 ) and 3 ( 4300 ). The mobile telephone charge management server ( 3000 ) makes an inquiry to a registration server ( 3100 ) as to whether or not proxy settlement is possible. When proxy settlement is not possible, the mobile telephone performs settlement using electronic money that has been deposited therein.
