Recently one of the main keywords representing of Korea is O2O The O2O market is an intersection of online commerce and offline commerce. The spread and popularization of smartphones transform payment market environment from online-based(PC) to mobile-based(Smartphone) which enable payment service expanses to on/off-line both markets. Due to this movement, data security is mo vulnerable than online-based payment service but the preference of serviceability, security threat becomes bigger.O2O service expansion is now at the stage of beginning with the limited influence, but could affect to the establishment of on/off line payment system of VAN and PG in the future. However, in the moment, the motivation to destruct the system is still weak. In this research, the possibility of Non-PG mobile payment service was suggested as a new way of mobile payment service by using PG. With suggestion, it could eliminate the issues of payment method beforehand and provide low fee to merchants.

In the case of Banque Paribas V. Banco Santander in England for the reimbursement request of deferred payment credit by the nominated bank, the L/C-issuing bank refused to pay the proceeds at maturity because of a fraudulent transaction. The reason of refusal was that the nominated bank, Banco Santander, had no right of payment in deferred credit before its maturity if it made payment of proceeds without notice to the issuing bank, that is, payment not based upon a credit transaction but on its own account. However, in the case of ADIB V. Fortis Bank in America, the New York court made the decision that the deferred payment bank could not refuse to reimburse to the nominated bank, Fortis Bank, because of fraud. Its decision was based on the UCP600. We have analyzed and investigated the above two cases-one was an English court's decision and the other an American's. The English court's decision was made under UCP500, but the American court's was made under UCP600, which was revised in 2007. As a result, we can expect that from now on in deferred payment credit transactions, the power of the nominated bank will be greater than before, but the issuing bank will bear the risk of the beneficiary's fraud, so the issuing bank will be hesitant to issue deferred payment credit. Notwithstanding, we thought that the New York court decision would come into effect in the activation of deferred payment credit in practical trade transactions.

As the payment service sector actively embraces artificial intelligence technology, "Voice Payments" is becoming a trend in contactless payment services. Voice payment services can execute payments faster and more intuitively through "voice," the most natural means of communication for humans. In this study, we selected richness, intimacy, and autonomy as factors for building trust with artificial intelligence agents. We wanted to determine whether the trust will be formed if the factors were applied to the voice payment services. The experiment results showed that the higher the richness and autonomy of the voice payment interface and the lower the intimacy, the higher the trust. In addition, the two-way interaction effects of richness and autonomy were significant. We analyzed and synthesized the collected short-answer system to identify users' anxiety when using voice payment services and proposed speech interface design ideas to increase their trust in the voice payment.

Electronic payment is a very crucial function in electronic commerce. As electronic commercial transactions develop on a mobile basis, a variety of electronic payment services that can be conveniently used are appearing. In particular, mobile easy payment services improve the user's convenience of payment and give a positive effect on activating online transactions. In this study we investigate empirically the factors influencing the user resistance to mobile easy payment services. Especially, we compares the main acceptance factors of the mobile easy payment services with the main acceptance resistance factors of the services. By doing that, we derive the implications that could contribute to the vitalizations of the mobile easy payment service market. The research model includes "perceived risk" as a main acceptance resistance factor, and "easy of use" and "usefulness" as the main acceptance factors. The relationship among these three factors, "use conflict", and "user resistance" is expressed in the model. We analyze the model by Structural Equation Model. The results proves that all the research hypotheses are adopted except for the impact of "ease of use" on "use conflict", and that users of mobile easy payment services think of "usefulness" more important than "risk".

A variety of services for mobile payments by the activation of FinTech have been developed. Various payment methods were developed, and an authentication method was developed to improve the reliability of the payment. On the other hand, when mobile easy payment services are used, they have weak security because the authentication by phone number. Therefore, this paper proposes a technique for increasing the reliability of the authentication process using the unique device ID of the mobile device to improve the authentication process based on the telephone number. The core research contents are the architecture and process for the authentication of mobile payments based on the mobile device ID. The mobile payment architecture consists of a mobile device, authentication service, and mobile payment application. The mobile device consists of mobile device ID and phone number, and the authentication server consists of authentication module and encryption module. The mobile payment service consists of a pre-authentication module and decryption module. The process of mobile payment service is processed by the encrypted authentication information (device ID, phone number, and authentication number) among mobile devices, authentication server, and mobile payment application. The mobile device sends the telephone number and the device ID to the authentication server and the authentication server authenticates the user through an authentication process and encryption process. The mobile payment application performs the pre-authentication process by decrypting the received authentication number. This paper reports a difference that can prevent the risk of leakage of the authentication number in existing payment services through the authentication process of the authentication server and the pre-authentication process of the mobile payment service of this paper.

This study develops an extended model to predict customer satisfaction in easy payment systems based on information systems success model. Our data was collected from easy payment systems users and analyzed using PLS. This study selected four variables as easy payment systems characteristics(convenience, variety, security, speed) along with gender being used as a moderating variable. The results showed that convenience and security are turned out to affect customer satisfaction. Additionally, the test of difference in gender revealed that with respect to gender, moderating effects exist in security and speed. This implies that this study can provide different promotion strategies according to gender. Overall, the proposed model could be used to predict customers' willingness to pay on the easy payment systems.

The recent trend in the payment terms of international trade shows the gradual shift toward more diversified payment methods (from L/C to not L/C) in order to cope with the increasingly dynamic international transactions in a more flexible manner. The reasons behind this recent shift are as follows : first, the global trade market is breaking away from the traditional L/C methods based on letters of credit toward a not L/C methods. nother reason for the changing trade payment methods is the increasing volume of intra transactions between headquarters and their foreign subsidiaries based on collection payment methods. Having mentioned the above problems that impede the Korean export insurance system, some suggestions can be put forward through a comparative analysis with foreign export insurance system. First, inducing private investments is one way of strengthening financial health of the KEIC. The KEIC also needs to diversify its insurance coverage adapting to the changing international trade environments.

This paper introduces a new credit card payment scheme called No Number Credit Card that can significantly reduce the possibility of credit card fraud. The proposed payment system is loosely based on Kerberos, a cryptographic framework that has stood the test of time. In No Number Credit Card, instead of card numbers, only payment tokens are exchanged between the customers and merchants. The tokens are generated based on the payment amount, payment type, client information, and merchant information. However, it does not contain the credit card number, so the merchant or a database hacker cannot acquire and illegally use any credit card numbers. The No Number Credit Card system is ideal for online e-commerce transactions and can be used with any credit card that users possess. It can be used with minor modifications to the current card payment system. We provide the principles of its operation through scenario analysis, a sample implementation, and a security analysis
