<p>A simple, safe electronic settlement system. A user terminal (20) such as a portable telephone is connected to a synchronous server (30) at a store by radio. A register terminal (10) in the store is connected to the synchronous server (30) through a leased line. The register terminal receives trade identification number for identifying the trade from the synchronous server and notifies the user of it. The user inputs the trade identification number into the user terminal to send it to the synchronous server. The synchronous server completes the settlement between the register and user terminals correlated with each other by means of the trade identification number. The register terminal authenticates the user through the synchronous server. Since the user completes the settlement without allowing the shop to know the user's personal information including the credit card number and the password, the security is improved.</p> |
