First Claim
1. An electronic payment system that makes electronic money payment relating to a dealing, comprising:
- a payment terminal operable to store a first balance of electronic money for said electronic money payment relating to said dealing;
a demanding terminal operable to communicate with said payment terminal to demand said payment; and
a payment apparatus operable to communicate with said demanding terminal and to store a second balance of electronic money to correspond to an identification number of said payment terminal for validating said payment, wherein said demanding terminal receives from said payment terminal said first balance stored in said payment terminal and transmits said first balance to said payment apparatus, and said payment apparatus detects unfair use of said electronic money by checking said first balance stored in said payment terminal, which was received from said demanding terminal, with said second balance stored in said payment apparatus.

Abstract
An electronic payment system for making electronic money payments for transactions. A payment terminal stores a balance of electronic money for payment on a dealing by electronic money. A demanding terminal communicates with the payment terminal to demand the payment and a payment apparatus communicates with the demanding terminal and stores a balance of electronic money to correspond to an identification number of the payment terminal for allowing settlement on the dealing. The demanding terminal receives from the payment terminal the balance stored in the payment terminal and transmits the balance to the payment apparatus. The payment apparatus detects an improper use by checking the balance stored in the payment terminal, which was received from the demanding terminal, with the balance stored in the payment apparatus. The system of the present invention provides secure and convenient electronic money payment for a user'"'"'s transaction.
