The purpose of this paper is to determine success factors important to electronic payment system and also to review its environments in order to present development direction of electronic commerce in Korea. A field survey including interviews and questionnaire surveys is made in 12 experts who were identified as having research experiences and/or development experiences of electronic payment systems, 35 merchants who are doing business over the Internet, and 96 netizens who were identified as a consumer group. In this study, we reviewed four dimensions affecting the acceptance of electronic payment systems such as safety, security, convenience, and efficiency. Finally, we suggested a total of 32 factors important to electronic payment systems and classified all factors into four dimensions.

전자상거래의 지불시스템에서 전달되는 데이터는 무결성, 기밀성, 부인방지등이 확보되어야 한다. SET 프로토콜의 지불게이트웨이는 이러한 요구 조건을 충족시키기 위해 계산량이 많은 RSA 암호알고리즘을 과도하게 사용하고 있는데 이로 인해 거래가 절정을 이루는 시간대에는 지불 게이트웨이에 과다한 비밀키 연산들이 집중되어 병목 현상이 발생하게 된다. 이러한 문제를 해결하기 위하여 SET 프로토콜의 지불시스템 승인단계에서 원타임패스워드를 적용하는 방안을 제안하고자 한다.

This paper analyzes the main factors affecting user selection of a small-sum electronic payment system using survey data of 396 users. Several findings emerge. First, users consider three pillars and eight factors in adopting a new system : system features(stability, security, and flexibility), transaction cost(payment commission and settlement period), and financial capability of provider(stability of financial structure, risk management capability, and funding capability). Second, the stability of the financial structure of the system provider is the most important factor to user acceptance of a new e-payment system. Users tend to consider uncertainty risk more seriously than transaction cost. This reflects the reality that electronic payment system service industry has not fully fledged yet. Third, some moderating effects exist according to payment methods and business usages. As for payment methods, speedy settlement cycle for wired/wireless phone payment, system stability for credit card and account transfer payment, and security for advance payment means are crucial factors. As for business usages, the stability of financial structure for online game content, system stability for music and video content, proxy payment commission for e-learning content, flexibility of the payment system for digital adult content, and security for public services are decisive ones.

Payment system is defined as the various contracts and operating facilities for the transfer of monetary value to clear the relationship between credit and debt. Payment systems essentially require the efficient and reliable operations. Card-based payment systems are developed practically and creatively in accordance with the progress of ICT. Especially in mobile environment with intelligent mobile devices such as smart-phones and tablets, a variety of payment services are provided. Existing card-based payment services are configured by the payment transaction initiated by the merchants card acceptance and then swiping into the CAT (Card Authorization Terminal) to begin the transaction. The merchant initiated payment services are now applied to the Wireless CAT (W-CAT) for mobile environment. That kind of payment services cause many problems such the illegal card information leaks and the lingering threat of W-CAT theft. Also, the use of many W-CATs increased cost to the merchant. In this paper, we propose the card holder initiated card payment system using the intelligent mobile devices in mobile environment for solving problems of the existing merchant initiated card payment system and coping effectively with the activation of a wireless data network and changes of information technology.

Purpose In this study, the difficulties were analyzed with the field data from two domestic and interview with industry practitioners. And We presented initiatives with feasibilities to overcome the hurdle for progress of easy-payment. Design/methodology/approach We collected industry data from two domestic credit card companies and analyzed that data to prove 7 proposition in detail. Also We had interview data from industry practitioners who can understand the relationship between stakeholders. For this analysis, we used the causal loop diagram to find activation inhibition and activation elements about easy-payment. Findings The Fintech easy-payment industry has been organically involved in various partners such as customers, merchants, PGs, VANs, credit card issuers, banks, payment providers, terminal manufacturers, etc. and they have been competing against each other to hold leader position in the easy-payment market. Because of the reasons, the easy-payment does not spread out as much as it expects. In this study, the difficulties were analyzed with the field data and interview with industry practitioners and proposed five initiatives with feasibilities to overcome the hurdle for progress of easy-payment. This study helps to understand current situation and issues of Fintech and easy-payment for related research in future.

현재 큰 성장세를 나타내고 있는 소셜커머스 서비스의 전자결제 시스템을 분석한 결과 대부분 결제금액을 변조할 수 있음을 발견하였다. 본 논문은 이러한 카드결제 시스템 상에서 발생하는 금액변조의 문제점을 해결하기 위한 방안을 제안한다. 제안된 방안은 소셜커머스 업체의 서버와 전자결제대행업체 서버간의 검증 체계를 추가하여 구매자가 결제흐름에 관여할 수 없도록 함으로써 결제금액 변조를 원천적으로 막는 방법이다.

전자상거래를 위한 전자지불시스템은 크게 전자화폐형, 전자수표형 그리고 신용카드형으로 분류할 수 있다. 각 방식에는 사용상의 특성으로 인하여 장단점이 있으나, 현재 현실세계에서와 같이 전자화폐지불시스템이 가장 활발하게 사용될 것이다. 그러나 전자화폐 지불시스템의 가장 큰 위험요소는 전자정보의 근본적 속성 즉 복사가 가능하다는 것이다. 이로 인하여 야기되는 화폐 검사에 대한 많은 비용이 발생한다. 본 연구에서는 기존의 전자화폐지불시스템에 따른 요구조건들을 알아보고, 스마트카드를 사용한 전자지불시스템에서 구현되어야 할 부가적 요구조건들을 제안한다.

Purpose In recent years, mobile payment service users have been rapidly increasing. Previous researchers focused on the mobile usage situation such as the elements of mobile payment service, usage pattern, and user behaviors, and the research that is approached from the viewpoint of the user is still insufficient. The aim of this study is to suggest a acceptance-resistance motivation model of choosing a mobile payment service based on the Herzbergs Two-Factor Theory by investigating users' motivation and hygiene factors. Design/methodology/approach For the purpose, literature reviews on factors of choosing a mobile payment service were conducted and classified motivation and hygiene factors. Two hypotheses were set as follows: Hypothesis I is that motivation factors have a positive impact on the choice of mobile payment service, and Hypothesis II is that hygiene factors have a negative impact on the choice of mobile payment service. To test two hypotheses, this study conducted an online questionnaire survey and a multivariate discriminant analysis. Findings The result found that mobile payment service is more likely to be replaced with mobile by improving convenience, simplicity, and ease of use that affect the acceptance motivation of mobile payment service. This result supported the Hypothesis I but not Hypothesis II and contributed to provide implications for future mobile payment service development and marketing utilization.

Current payment methods have many faults which are detrimental to the formation and completion of a project. This includes the use of unfair payment terms, pricing strategies and payment mechanisms between the contracting parties. This resulted in being criticised and remain in doubt, the use of current payment methods to reward good contractors and to distinguish poorly performed construction firms. In order to have an insight into this issue, a structured survey was conducted amongst UK construction practitioners. It was found that traditional pricing methods (i.e. lump sum and unit price), payment methods (i.e. interim valuation) and retention still dominate current practice. The empirical findings show that there are significant differences in the use of pricing and payment methods (when making and receiving payments) in construction. Significant differences also found in the factors affecting the choice of pricing methods when making (and receiving) construction payments. The paper concludes with analysis of the findings and future direction of research in payment systems is also provided.

As financial transactions using mobile devices have been activated, mobile payment services have appeared and many changes have been made to the existing financial service methods. Due to the simplified payment method of mobile payment service, security threats such as personal information leakage, phishing damage, and malicious code are increasing. Research that can solve this is needed. In this paper, we discuss the features and security factors of mobile payment system. In order to improve the security of mobile payment system, we propose a fault analysis method based on frequency of occurrence using Fault Fishbone Analysis(FFA) technique.
