AN ELECTRONIC TRADING METHOD

摘要

An electronic trading method prevents unjust trading relative to prices or goods in an electronic trading using valuable data such as electronic money as settlement means. A broker server which temporarily stores electronic money, for example, is connected to a communication network. When electronic money is sent as a price of goods from a terminal of a goods consumer to a server of a goods merchant, the sending of electronic money is performed in two steps including sending of electronic money from the terminal of the consumer to the broker server and sending of electronic money from the broker server to the server of the merchant. The sending of electronic money from the broker server to the server of the merchant is performed when a predetermined settlement condition including a condition relative to the elapse of a designated date or reception of a receipt issued by the terminal of the consumer is brought into existence. When the consumer does not receive goods although a predetermined delivery date of goods has elapsed, the terminal of the consumer transmits a command for prohibiting settlement to the broker server. When the broker server receives the command, the broker server does not sent electronic money to the server of the merchant even if the settlement condition is brought into existence.
