본 연구는 간편결제 서비스에 대한 지각된 유용성 및 신뢰가 결제 서비스 이용에 대한 충성도 및 해당 쇼핑몰에 대한 충성도에 미치는 영향을 분석하였다. 또한 간편결제 서비스에 대한 사용자들의 지각된 유용성 및 신뢰에 사용자 개인 특성 및 결제 서비스 브랜드에 대한 인지도가 미치는 영향을 함께 검증하였다. 20대-40대 사용자를 중심으로 온라인 설문을 실시한 결과, 소비자들이 간편결제 서비스를 사용하면서 서비스 시스템에 대한 유용성을 많이 느끼고 서비스 제공자에 대한 신뢰가 높을수록 간편결제 서비스에 대한 충성도 뿐 아니라 결제 서비스를 제공한 해당 쇼핑몰에 대한 충성도 또한 높아지는 것으로 나타났다. 또한 결제 서비스에 대한 지각된 유용성 및 신뢰는 소비자 개인의 기술혁신성, 스마트폰 활용 정도 및 서비스 브랜드 인지도에 영향을 받는 것으로 나타났다. 본 연구는 온라인 또는 모바일 쇼핑환경을 제공하는 기업들이 결제 시스템을 쇼핑 사이트에 부가된 요소로서 판단하는 것이 아니라 사이트 자체의 한 구성요소로 인식하여 사이트 디자인에서부터 설계하고 구현해야 한다는 것을 보여준다.

This study aims to examine the factors that affect the intention of merchants to adopt mobile payments in Saudi Arabia. The underlying model used in the study is the technology acceptance model, which includes two factors: perceived ease of use and perceived usefulness. The effects of trust, cost, and compatibility are also examined because these are among the common factors used based on the literature. An online questionnaire was completed by 242 merchants in Saudi Arabia who had already adopted mobile payment services. A significant relationship was identified between perceived usefulness and compatibility in terms of merchants' intention to adopt mobile payment systems, while an insignificant relationship was identified with perceived ease of use, trust, and cost.

Purpose In order to find out the influential factors to accept the mobile convenient payment service like Apple pay or Samsung Pay based on the Unified Theory of Acceptance and Use of Technology according to the type of High and Low value payments. Design/methodology/approach This research model is designed on the factors of Unified Theory of Acceptance and Use of Technology and simultaneously analysed, or performed the empirical analysis of the PLS-SEM(Partial Least Squares structural equation model) in order to forage for the association among mobile convenient payment service's features. Findings According to the empirical analysis consequence, this research confirmed that the adoption of mobile convenient payment services is influence by features on the basis of Unified Theory of Acceptance and Use of Technology, mobility, and trust. Also, this paper figure out that the behavior of an user acceptance of mobile convenient payment services according to the type of high and low value payments.

In this research, we study the impact of the factors that predict consumer loyalty of mobile payments and mobile wallets usage in Thailand. We developed a research model based upon previous findings where we propose and examine four constructs of personal innovativeness, consumer attitudes, consumer satisfaction and loyalty. In general, all of the hypotheses were supported by variables related to consumer loyalty with mobile wallet usage. Personal innovativeness analyzed due to its potential mediation effect on loyalty, both from attitudes and from satisfaction. It was found that personal innovativeness was a mediator construct in predicting consumer loyalty. The overall model provides value to the mobile payment and mobile wallet application providers in term of improving service efficiency and business strategies to secure Thai consumer loyalty.

최근 핀테크 활성화로 인한 금융 거래 및 결제 관련하여 많은 연구 개발이 활발하게 진행되고 있다. 상품을 구매하고 대금을 지급하는 방법에는 현금, 카드 등 여러 가지 방법으로 결제를 진행하고 있으며, 최근 모바일 카드를 통한 결제 및 휴대폰 간편 결제 등 결제 방식이 빠르고 간편화 되고 있다. 제안하는 모바일 전자결제 방식은 기존 카드 리더기 또는 카드 단말기 없이 사용자의 휴대폰을 이용하여 결제할 수 있는 방법을 제안한다. 결제 시 스마트폰에 내장된 지문인식기를 통해 사용자의 생체정보를 입력받아 본인인증이 먼저 수행되며, 결제 이전 두 사용자의 확인을 위해 인증된 기관에서 부여 받은 인증 코드를 전송하여 이를 검증하고 결제가 이루어진다. 사용자의 생체정보와 결제관련 정보는 스마트폰 내의 안전한 FIDO TEE영역에 저장되어 악의적인 사용자로부터 안전성을 확보하였다. 키의 안전성 측면에서는 모든 키 생성은 FIDO TEE 영역에서 이루어지게 하여 안전성을 확보하였으며, 스니핑, 중간자 공격 등 다양한 공격 방식에 대한 무력화를 통해 안전한 모바일 전자결제 서비스를 제공한다.

Mobile wallets have been in continuous demand and developed over the past few years, especially during the COVID-19 pandemic. Several studies have examined user intentions and perspectives. This study develops a conceptual model combining behavioral factors with the technology acceptance model (TAM). The goal is to identify key factors that influence user's intention to adopt mobile payments. This study uses the TAM and the unified theory of acceptance and use of technology (UTAUT) models with additional factors. The additional factors are security, trust, facilitating conditions, and lifestyle compatibility. The study analyzes the results of a survey of 394 Saudi citizens conducted via an online survey. The results indicate that user attitudes and intentions are positively influenced by all of the factors. Perceived usefulness, perceived ease of use, lifestyle compatibility, and facilitating conditions are direct predictors of user behavior in accepting mobile wallet payments. This study provides an empirical contribution to the literature on mobile payment acceptance on the effect of perceived usefulness and lifestyle compatibility. The results demonstrate that about 26% of the respondents started using mobile wallet services because of the COVID-19 pandemic.

Secure digital payment is critical in the successful shaping of global digital business. Digital payments are increasingly being used as a substitute to traditional payments, contributing markedly to the efficiency of the economy. The focus of every digital business transaction is to minimize risks arising from transactions. It is essential to ensure the security of digital payment whether used in internal networks or over wireless Internet. This paper analyses secure digital payment methods from the viewpoint of systemic security and transaction security. According to comparative analysis of digital payment models, this paper proposes a comparative analysis framework to investigate and evaluate secure digital payment. In conclusion, the comparative analysis framework, comparison of digital payment models and mobile payment models proposes a useful academic and practical foundation to enhance the understanding of secure digital payment methods. It also provides academic background and practical guidelines for the development of secure digital payment systems.

In this paper, we propose the authentication server system that prevent hacking in In-app billing applications. And we also propose the methods to verify electronic receipt for the payment of internal app payments and to check the integrity of the applications. Then we designed the payment metabolic system that checks between products-offer list and paid subscription if payment system is hacked with new hacking technologies different from existing ones. And then we implemented proposed authentication system and experimented with about 10,000 average internal application payments per an hour. It shows that proposed system has defensive techniques that counter attacks against in-app billing but it takes more than 0.8916 seconds than no-certification system that is considered as relatively short time.

RFID enabled credit cards are becoming increasingly popular as contactless credit cards. We envision a future where RFID credit cards will be used for online shopping. RFID system has tremendous potential to render electronic payments more secure than normal credit cards. The word RFID enabled credit cards may bring in mixed passion, enthusiasm and perhaps even rage! This is partly paranoia and partly reality. The reality is that an intruder can read RFID cards without the user even noticing it. This brings in a zone of discomfort and leads to paranoia. Certain interactivity should exist to bring back this comfort to the user. This paper tries to make an effort in that direction. In this paper we propose mobile phone based architecture for secured electronic payments using RFID credit cards.

본 연구는 모바일 이커머스 페이 원터치 결제 시 심리적 안정감을 제공하는 사용자 경험을 연구하는 데 목적이 있다. 문헌 조사와 사례연구를 통해 이커머스 페이 원터치 결제를 파악하고, 설문과 심층 인터뷰를 통해 사용자 경험을 조사하였다. 애런 윌터(Aarron Walter)의 사용자 욕구 단계(Hierarchy of User Needs) 모형을 토대로 작성한 설문은 원터치 결제에 대한 기능성, 사용성은 높은 평균값을 받지만, 신뢰성과 안정감은 다소 낮게 나타났다. 이후 사용자 관점에서 바라본 사용자 경험 디자인(A User's Eye View of User Experience Design) 모형을 바탕으로 진행된 심층인터뷰를 분석하여 심리적 안정감을 보완하기 위한 디자인 개선안 네 가지를 제시하였다. 이 연구는 원터치 결제 시 안정감을 느낄 수 있는 결제 경험 기초 연구에 도움이 될 것으로 기대한다.
