Abstract

Disclosed are an electronic settlement system, an electronic settlement method, and a cash payment method using a barcode displayed on a mobile terminal, thereby performing member identification using the barcode including member information, electronic settlement services (such as credit card settlement, direct payment card settlement, advance payment card settlement, small amount settlement, and Giro system settlement) at various shops via a procedure verifying whether a user is an actual owner of the barcode, cash payment services via member information barcode and member identification procedures, advance payment card services by depositing a designated amount of money at a database of the bank and allowing the user to systematically use the advance card within the deposited money, and wireless banking services for transmitting and receiving various banking related data via wireless network between the bank and the members.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 10 / 475,414 filed Oct. 22, 2003, which is the National Stage of International Application No. PCT / KR02 / 00745, filed on Apr. 23, 2002, and claims priority from and the benefit of Korean Patent Application No. 2001-21791, filed on Apr. 23, 2001, which are all hereby incorporated by reference for all purposes as if fully set forth herein.BACKGROUND[0002]1.

AI Technical Summary

Benefits of technology

[0010]Exemplary embodiments of the present invention provide an electronic settlement system, an electronic settlement method, and a cash payment method using a LCD barcode displayed on a LCD window of a mobile terminal such as a cellular phone, a PDA (Personal Digital Assistant), or a pager, thereby removing the conventional inconvenience in possession and danger in loss of credit cards and the conventional inconvenience in recharge in smart cards, promoting wireless banking services via wireless network, and integrating the credit card service as settlement means and the smart card service as electronic currency means.

Problems solved by technology

The aforementioned conventional systems have several problems as follows.

First, it is not easy to possess a plurality of the magnetic cards.

As the number of banks for which a member registers increases, the number of cards issued by different banks and then possessed by the member also increases, thereby causing an inconvenience and increasing the possibility of loss.

Particularly, the number of cards possessed by one member, including department cards and customer management cards at each shop as well as the bank credit cards, drastically increases, thereby being difficult in management.

Second, in case of the smart card, the IC chip for storing electronic currency is installed within the mobile terminal, thereby increasing the production cost of the mobile terminal.

Further, after the stored money is completely spent, the IC chip must be recharged, thereby making the member to go to a charging station and generating an inconvenience to the member.

Further, a cash payment service cannot be provided to the member via the smart card system.

Third, since the conventional credit card service system cannot receive various messages from banks or department stores, it cannot various banking services.

Further, in case of introducing new products of the banks or the department stores, the magnetic card cannot transmit and receive various service related messages.

Fourth, since the credit card service using the magnetic card and the smart card service using the IC chip are two separate services, it is difficult to integrate two services one thing, thereby causing complicate matters to the members.

Therefore, it is impossible to provide an integrated banking service to the members.
