Abstract

A portable terminal, when receiving an exchange offer message of electronic values from a portable terminal, notifies an application program of an exchange offer content based on a listener corresponding to the message. When the application program accepts this offer content and when electronic values are determined as exchange objects, the portable terminal returns an exchange confirmation message of the electronic values. When the portable terminal receives the exchange confirmation message, it notifies an application program of an exchange content based on a listener corresponding to the message. When the application program accepts the exchange content, the exchange transaction of electronic values is started.
