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".

The purpose of this research is to investigate the factors that impact customer satisfaction and loyalty in mobile payment services. Specifically, this research (1) studies the influence of company reputation on customer satisfaction and loyalty, (2) examines service quality dimensions that increase customer satisfaction, and (3) assesses switching barriers as moderators in influencing customer loyalty. Findings of this empirical research reconfirm the point of view that company reputation, service quality, and switching barriers are crucial for customer satisfaction in mobile payment services. The research methodologies that were used to verify the hypothesis in this study included customized surveys and structural equation modeling. The results demonstrated that company reputation significantly affects customer satisfaction and loyalty. Additionally, the results indicated that only two of the five total service qualities, ease of use and the security/privacy qualities, have positive influences on customer satisfaction. Customer satisfaction has also proven to be a significant influence on loyalty. Lastly, the results showed that among the factors of switching barriers, the factors of lost performance costs, sunk costs, setup costs, the attractiveness of alternatives, and service recovery have moderating effects on the relationships between customer satisfaction and loyalty. Base on the results, this research recommends that firms aim at devising integrated strategies that make switching barriers act as complements to customer satisfaction.

핀테크는 금융과 ICT기술을 결합한 새로운 형태의 금융서비스를 칭하는 용어로 글로벌 ICT 기업 또는 금융기관이 확보중인 폭넓은 사용자층을 기반으로 송금, 결제, 대출, 자산관리 등 다양한 금융서비스를 결합하여 제공하는 새로운 형태의 금융서비스를 말한다. 국내 핀테크의 경우 모바일 디바이스를 중심으로 한 간편결제 서비스가 핀테크 서비스 산업 중 큰 부분을 차지하고 있으며, 다양한 영역으로 확장하기 위한 연구가 활발히 진행되고 있다. 관련 정책 또한 2015년 6월 공인인증서 의무 사용 폐지 등 핀테크 산업을 활성화하기 위한 다양한 정책들이 발효되고 있지만, 많은 규제 등으로 인해 어려움을 겪고 있는 실정이다. 핀테크에 대한 국외 동향으로는 페이팔(Paypal), 알리페이(Alipay), 트랜스퍼와이즈(TransferWise) 등을 통해 알 수 있듯이, 모바일 디바이스만을 중심으로 한 간편결제 외에도 다양한 형태의 금융 결제 서비스를 제공하고 있으며, 다양한 형태의 핀테크 산업을 육성하기 위한 정책을 마련하고 있다. 본 고에서는 핀테크의 개념과 발전 배경 등에 대해 설명하고, 국내 외 핀테크 서비스 및 정책 동향에 대하여 분석하고, 마지막으로 국내 핀테크 서비스 발전 방향에 대하여 제안한다.

Since 2014, ease of regulations on financial institutions expanded the mobile payment market based on simple authentication, and this resulted in the emergence of various simple payment services. Although several security solutions have been used to mitigate possible security threats to payment applications, there are vulnerabilities which can still be found due to the structure in which the security solution is applied to the payment service. In this paper, we analyze the payment application and security solution from the process perspective, and prove through experimentation that verification functions of security solutions can be bypassed without detailed analysis of each security function, but by simply manipulating the verification result value. Finally, we propose methods to mitigate the bypass method presented in this paper from three different perspectives, and thereby contribute to the improvement of security level of the payment service.

The easy payment service is a payment and remittance service that uses a simple authentication method. As online transactions have increased due to COVID-19, the use of an easy payment service is increasing. At the same time, electronic financial industries such as Naver Pay, Kakao Pay, and Toss are diversifying the competition structure of the easy payment market; meanwhile overseas fintech companies PayPal and Alibaba have a unique market share in their own countries, while competition is intensifying in the domestic easy payment market, as there is no unique market share. In this study, the participants in the easy payment market were classified as electronic financial companies, mobile phone manufacturers, and financial companies, and a SWOT analysis was conducted on the representative services in each industry. The analysis examined the user reviews of Google Play Store via a topic modeling analysis, and it employed positive topics as strengths and negative topics as weaknesses. In addition, topic modeling was conducted by dividing news articles into political, economic, social, and technology (PEST) articles to derive the opportunities and threats to easy payment services. Through this research, we intend to confirm the service capabilities of easy payment companies and propose a service activation strategy that allows gaining the upper hand in the market.

As a new alternative to cash and credit-cards, mobile payment has been attracting world's attention. Although fin-tech, a mobile payment system provider, has been a rising issue, mobile payment systems is not yet widely used domestically.

In this study, surveys were conducted to identify the components that affect the overall trust of a mobile payment system. It has been concluded that cognitive trust, affective trust, trust in system quality affect the overall trust of the system, and this trust affects the continuance intention of users.
