Global Electronic Trading means that trading partners trade each other via Global Electronic Trading Network, that is, global business to business electronic commerce. Electronic payment systems are how to make payment electronically in manner that is efficient, reliable, and secure. I suggest the Electronic payment systems such as TradeCard and SWIFT enable seller and buyer to conduct and settle international B2B electronic commerce in case of solving the above problems. And, where the cargo arrives ahead of the B/L, the importer cannot take delivery of the cargo without the B/L. This situation is referred to as the B/L dilemma. But the BOLERO system will resolve this B/L dilemma. Bolero Project is developing a cross industry utility platform for the secure, electronic transfer of commercial trade information world wide.

According to the recent increase of mobile commerce, the researches on electronic voucher payment based on NFC are lively made. However, most researches focus on the payment method using electronic vouchers, and so there is none for tracking circulation history of an electronic voucher. To address this problem, this paper proposes the method to store circulation information of an electronic voucher. The proposed method applies Object Memory Model (OMM) to an electronic voucher. When an electronic voucher is issued, transferred to other person, and used in payment, related information is stored at the object momory of an electronic voucher. So, our proposed object memory has three types of blocks, on which each information for issue, transfer, and payment of an electronic voucher is stored. We can retrieve and analyze the circulation history of an electronic voucher using this information. In the future, we will implement the proposed an electronic voucher and propose the method to analyze circulation information.

This study is directed to compare the payment systems between conventional and internet, under international commerce. A stable and secure payment system is necessary for the progress of e-business through the internet. There are three typical methods of payment system in conventional transactions; the letter of credit(L/C) basis, the collection basis and the remittance basis. The exporter prefers L/C basis because of authentic payment, financial convenience and reduced risk Buyers and sellers who have enjoyed long creditable relationships use carefully the collection basis. The remittance basis is adequate for small amount payment for sample. In this paper, the merits and demerits of electronic payment system are compared to the conventional payment one. Internet payment system has an advantage of speed-up in payment against the conventional, but has a limited usage in the area of consumer based(B to C) transaction. The conventional payment system has been becoming overwhelm electronic payment one in the business to business(B to B) area.

An electronic receipt (e-receipt) is a receipt issued electronically in place of a traditional paper receipt. This e-receipt, which can be accessed on a smartphone or online, allows for the exchange of goods, refunds, and other services without a paper receipt. The government is focusing on widespread dissemination of e-receipts to realize a society without paper by 2020. Introduction of the e-receipt has begun in mainly large marts and coffee shops, and recently, major franchise convenience stores. As a result, individual customer's transactions are being converted into electronic transactions, and the payment methods are changing to card-based electronic payment services or prepaid electronic payment services. The number of non-paper commercial transactions are also on the increase. In this paper, we try to identify the e-receipt industry ecosystem by analyzing the industries and markets participating in the process of receipt issuance from the perspectives of storage, management and disposal, and to analyze the domestic industrial and social economic effects expected from the spread of electronic receipts.

The main purpose of this study is to analyse what are the key financial innovations in the euro area electronic payment systems. TARGET2 is the RTGS-system provided through the Eurosystem. It is used for settling central bank operations, for large interbank transfers in euro and also for other euro-denominated transfers. The specific features of TARGET2 include processing in real time, settlement in central bank money and immediate finality. In addition, the SEPA is a payment-integration initiative of the European Union for simplification of bank transfers denominated in euro. In particular, the main innovations consist of the completion of the phased migration to the TARGET2 infrastructure, and the introduction of a single retail payment market in euro - the SEPA and its products, schemes and frameworks. As the study analyse, the key innovations consist of the TARGET2 introduction, SEPA establishment and migration towards the T2S system. These innovations will lead to a better understanding of the payment and settlement systems' behavior in stress situations and to enhance the stability of the euro area financial system. Moreover, the successful integration of the European payment and settlement infrastructures will further contribute to the integration of the European financial markets, as well as to their higher competitiveness.

The purpose of this paper is to examine whether the international electronic payment system through IDENTRUS can be active in the future or not. For this purpose, we have reviewed the various aspects of the typical systems : their types, operational mechanisms and actual limitations in real trade. Then we have proceeded to examine the distinguished features of IDENTRUS in terms of operational procedures and characteristics by comparing to other systems. Specially as the preconditions of activation, the possibilities of cost down, time reduction, risk hedging and operational efficiency have been studied. Thus we are not sure that the IDENTRUS will have a position as a main stream in the future electronic payment system, but this system would contribute positively to the establishment of electronic payment system if some functional additions will follow.

In recent years electronic fund transfers covered by the Electronic Fund Transfer Act 1978 for consumer protection and the Article 4A of Uniform Commercial Code(U.C.C.) 1989 for wholesale electronic payments in United States. Electronic fund transfers carried out by use of a wire transfer network, automated clearing house, or other communication system of a clearing house or other association of banks such as direct deposit, Fedwire, automated teller machine, point-of-sale, and credit card transactions have been increasingly common in consumer transactions and wholesale transactions. Especially, the Article 4A of U.C.C. governs the rights and obligations associated with transactions such as an issue and acceptance of payment order, execution of sender's payment order by receiving bank, and payment. These legal frameworks in connection with electronic fund transfers in United States can play a leading role in establishing model not only within the United States, but also as a basis for developments of electronic commerce law in Korea including other countries.

Commerce activities which are free form space and time constraint using a communication network are called Electronic Commerce(EC). Because of sending a commercial information using open network such as Internet in EC, they need the security of commerce information (payment information and purchase information), checking the integrity of transferring data and certifying all parts participated in commerce for a secure commerce. Recently Visa and MasterCard Co. released the Secure Electronic Transaction (SET) Protocol for secure payment card transaction on Internet. This paper proposes a Secure Electronic Commerce Transaction Model(SECTM) using SET in order to support the secure commerce on Internet. The proposed transaction model prevents merchant from abusing the cardholder's payment information (credit-card number etc.) and enables cardholder to shop securely in Electronic Shopping Mall.

Dedicated Short Range Communications(DSRC) as a prominent communications candidate for Intelligent Transportation Systems(ITS) have been developed to support ITS applications such as value-added information service, e-commerce, electronic toll payment, etc. These various applications associated with electronic payment through unsecure communication channel of DSRC suffer from security threats. To ensure secure payment, we have adopted appropriate cryptographic mechanisms including encipherment, authentication exchange and digital signature. The cryptographic mechanisms require to use cryptographic keys established between two communication entities. In this paper, we propose a secure electronic payment system which is designed to have some functions for strong authentication, encryption, key agreement, etc. Especially, we adopt domestic developed cryptographic algorithms such as EC-KCDSA and SEED for digital signature and block cipher, respectively. We can show those mechanisms are appropriate for the secure electronic payment system for ITS services under the DSRC wireless environment in aspects of constrained computational resource use and processing speed.

An electronic micropayment system, one of electronic payment systems, is suitable especially when a small amount of money is to be paid frequently in order to purchase on-line goods (i.e. database search, software distribution, electronic news service, etc). In addition, since the amount of payment is small, possible damages caused by system failures are lower than other payment system. In this paper, a micropayment protocol in electronic commerce environments on the Internet is proposed, based on the PayWord system. And a micropayment electronic commerce system which executes the protocol proposed is implemented. Unlike the PayWord system, however, the micropayment protocol proposed in this paper is designed in such a way that a merchant does not need to request a payment at the end of every business day since a customer cannot purchase goods beyond length of hash chains, which is specified on a certificate. In addition, the system is able to check the validity as well as the duplicate spending of hash chains. The electronic micropayment system with the proposed protocol is consists of Customers, Merchants, and Brokers. Customers are implemented on Windows NT 4.0 using VC++. Merchants are implemented on Solaris 2.5.1 and gcc 2.8.0 using Netscape Web Server and CGI Methods. HP UX 10.20 is used for Brokers.
