The international trade industry is on the brink of a radical Internet-driven transformation. TradeCard is a payment and settlement system that is an alternative to letters of crdeit. That is, TradeCard is a business-to-business e-commerce infrastructure that enables buyers and sellers to conduct and settle international trade transactions securely over the Internet. Paperless, payment-guaranteed international trade transactions - which eliminate the traditional letters of credit with electronic certifications - are widely considered the most difficult B2B transactions to conduct. The TradeCard system was initially built to accommodate and process this complex, cross-border payment type at a US$100 service fee for each transaction of up to US$100,000 since November 1999.

Purpose - The bank payment obligation is a transaction method that combines the certainty of L/C transactions with the speed of remittance payments, so the main purpose of this study is to highlight the superiority of bank payment obligation, noting the difference between bank payment obligation and L/C transactions. In addition, we would like to examine how bank payment obligations can actually be applied to support various valuable proposals such as post-shipment and post-shipment finance according to the payment process.. Design/methodology - This study focused on literature based on data from ICC and SWIFT along with previous domestic and international studies. In terms of a research method, a literature review was adopted with electronic trade-related books and journals and policy-related reports from international trade-related agencies. Findings - Unlike L/C transaction, BPO transaction verify the data inquiry process based only on the combination result of the established baseline and dataset. Accordingly, it is superior to L/C transaction in that there is no confrontation between the parties over the results of the inquiry, and clear transactions are possible according to the principle of proof after prepayment. In addition, unlike credit transactions, data inconsistency acceptance procedures confirm payment obligations in consideration of importers' intentions. As a result, as long as trade documents are in the hands of exporting countries, flexible document disposition is possible in response to the situation after payment, which is more advantageous than L/C transaction. Originality/value - Specifically, from the importer's point of view, BPO transactions have the advantage of reducing the manpower required to prepare and review trade documents and processing transaction negotiations with exporters advantageously due to the strength of payment obligations. From the perspective of the exporter, it has the advantage of enabling rapid recovery of trade payments and reducing the risk of importer's cancellation of transactions or content change. From the perspective of participating banks, it is possible to strengthen relations with importer and obtain high commission income by increasing the role of bank reduced by reducing L/C transaction.

전자상거래에서 중요한 지불 수단으로 떠오르고 있는 전자화폐 시스템에 있어서 사용자에의 익명성 제공은 기존의 지불 시스템에서 제공하지 못하는 중요한 요소이다. 그러나 사용자 익명성을 악용하여 각종 범죄 활동에 이용하려는 시도가 발생할 수 있으며 전자화폐 시스템 도입시 이에 대한 대책도 함께 강구되어야 한다. 따라서 본 논문에서는 전자화폐의 효율적 사용을 위해 분할성 기능과 함께 화폐 추적과 사용자 추적 기능을 제공하는 효율적인 전자화폐 프로토콜을 제안한다.Abstract Electronic Cash System is an important payment method in Electronic Commerce. The anonymity of users is an important issue in such systems, but the issue has not been addressed by previous payment methods. User anonymity can lead to a system that is vulnerable to various criminal activities. Therefore, e-cash systems must consider ways to prevent such criminal activities. In this paper we suggest an efficient e-cash system that eliminates the vulnerability of the system by using the divisible ability of the system with the coin and owner tracing.

A Bank Payment Obligation is now in operation as payment instruments in the business of Supply Chain Finance since 2013. The BPO is an irrevocable undertaking of the Obligor Bank subject to the successful electronic matching of all required Data Sets with the established Baseline in the TMA. Although the BPO should be regarded as similar to a Letter of Credit, it is a new payment solution based on a technology and data-driven mechanisms. The BPO is different from the letter of credit in their structure such as a bank to bank obligation, an automated matching engine, a transfer and confirmation of the Credit, etc. The BPO can also be used more effectively on a stand-alone solution as an electronic alternative to the traditional instruments. it will provide a new range of solutions to meet the ever-changing needs of the trade customers. However, the BPO could be raised several issues including an assurance of payment between recipient banks and sellers because the BPO is a bank-to-bank obligation.

This article want to discuss on comparative research between CHIPS and Fedwire as the cross-border payment systems which America have and use at present. CHIPS is a New York-based automated private-sector clearing facility for large-dollar transfers. It is a central switch communication and settlement system whose 53 participating banks exchange same-day payment messages over dedicated communication lines linking each one to the CHIPS central computer. On January 22, 2001, CHIPS introduced immediate finality for payment released from the CHIPS queue. Unlike the Fedwire system, The CHIPS system is not a real-time gross settlement system. Instead, CHIPS is hybrid system that uses a computer program to select payment order in a queue for release to the receiving bank. CHIPS are governed by CHIPS Rules and Administrative Procedures. Fedwire system is a nationwide electronic fund-transfer system facilitating same-day transfers throughout the United States. It is a gross settlement system providing immediate credit to the receiving bank's master account. Communicating between a Federal Reserve Bank and Fedwire users can be either on-line or off-line. Fedwire transfers are governed by Subpart B of Regulation J, issued by the Federal Reserve Board, which incorporates U.C.C. Article 4A but preempts or supersedes any of its inconsistent provisions.

Recently, the use of prepaid electronic payments such as electronic wallets, digital currency and prepaid points is gradually increasing. Prepaid electronic payments has the characteristic of being used after charging first. This study empirically investigated the factors affecting the intention to use online charging in order to help improve the service that require prepaid recharge by applying transformed TAM. Since there are not many previous studies for the intention to use online charging, we extract factors through preceding researches for electronic cash and mobile easy payment. Also we analyze the intention to use online charging for transportation card users, focusing on the moderating effects. As a result of the study, it was found that 'convenience', 'ubiquity', and 'self-efficacy' among the independent variables had a positive (+) effect on mediation variable 'perceived usefulness'. 'Perceived usefulness' was analyzed to have a significant influence on the dependent variable 'usage intention'. According to users' gender, internet usage time, internet shopping frequency, online charging frequency and transportation card usage type, the moderating effect was significant on 'perceived usefulness' and 'usage intention'. As an implication, it was suggested that service improvement and differentiated marketing are needed in direction of increasing the usefulness of services. Additional research directions were proposed for services such as e-wallets, prepaid points and digital currencies by adding other factors and moderate variables.
