An electronic asset utilization system is constituted of a stationary terminal 11, such as a set-top box (STB), a mobile terminal 13, such as a portable cellular phone, and a server 15. The server 15 receives an order for an electronic asset from the stationary terminal 11 or the mobile terminal 13; downloads to the stationary terminal 11 or the mobile terminal 13 an electronic asset and an exchange or receipt certificate to be described later; retains the thus-issued electronic asset, exchange certificate, or receipt certificate; and settles a charge billed to the thus-ordered electronic asset.
The stationary terminal 11, the mobile terminal 13, and the server 15 are connected to a communications network.
