## Abstract

In a settlement transaction system or settlement transaction method using the system, the system includes a content providing server conducting a digital broadcast, for example, for a CS broadcast, a BS broadcast, a CATV, or a broadcast using ground waves; a settlement server to execute settlement transaction or settlement transaction, an order placement managing server to execute order placement processing, and an order managing server which receives an order of a request from a user to purchase articles and which sends an associated indication to the settlement server and the order placement managing server according to information of the order. The user operates a terminal in which an IC card communication application to communicate with an IC card is only installed. It then becomes possible to reduce a load imposed onto the system in association with a change to an existing digital broadcast system.
