Mobile easy payment is a term for using mobile devices to facilitate financial transactions. Mobile easy payment is a quickly emerging practice, supported by the dramatic increase of mobile phone or device users around the world. The purpose of this study is to classify user's group of the mobile easy payment service by their lifestyle based on I-VALS type and to investigate differences in usage behavior among the user groups. For empirical study, a questionnaire survey was carried out with users of mobile easy payment services using the Internet from June 7 to 10 in 2016. We conducted factor analysis for I-VALS, usage factors, satisfaction factors. We also performed cluster analysis for group classification, and analysis of variance, cross analysis to compare the different usage behavior among the user groups. In analysis results, first three cluster appeared including "ICT task-oriented group", ICT positive and socialities oriented group", "ICT leader-oriented group". Second, it was found significant differences among the clusters about factor of "easy of use", "securities", "universality", "satisfaction". Third, we showed that there were significant differences in time first used the service. Based on these findings, we provide practical implications. Results of our study can be expected to provide the basis of differentiated marketing strategy of mobile easy payment services.

Purpose The purpose of this study is to deduct the motivative factors such as perceived value, trust, innovative resistance and flow from the pervious studies and to examine the effect of the motivative factors in the continued use of convenient payment service. Design/methodology/approach This study made a design of the research model by integrating the factors deducted from the Value-based Adoption Model and the Innovative Resistance Model with the factors deducted from the Flow Theory. Findings Results showed that perceived value had a significant effect on trust and innovative resistance. Moreover, trust had a significant effect on flow and continued use. Finally, innovative resistance and flow had a significant effect on continued use. However, the research model in this study was derived from a behavioral point of view, therefore, this model needs to combine the various factors of related fields.

In this study, we analyzed service quality factors of O2O delivery app based on Kano model and survey, and classified service quality into several dimensions. As a result of the analysis, the one dimensional quality factors were accurate information transmission, variety of restaurants, diversity of payment methods, diversity of menu selection, discomfort resolution, kindness of service, taste and quality of food, hygiene and cleanliness, Attractive quality factors such as updated information, reliable reviews, various ordering methods, fast delivery, brand image, discount point payment and accumulation. Although the must-be quality factor did not appear, it turned out that the discomfort resolution was close to the must-be quality factor. The indifferent quality factors were informational services, events and promotions. The O2O delivery app market is continuing to grow and competition is getting more and more intense. The results of this study will help O2O delivery app vendors to establish strategies to focus on certain quality of service factors.

Purpose As the mobile easy payment service grows fast, competition in the payment service market is getting stronger. On the other hand, there are few studies on the users' utilization results. Therefore, this study explains the continuous use intention of mobile easy payment Services based on PAM and value model. Design/methodology/approach This study proposed an extended model by integrating PAM, which is a representative model of continuous use intention in IS field, and value model of mobile field. Also this study empirically tested 298 users who have experience of mobile easy Payment service. The structural equation model was used to verify the research model and hypotheses. Findings According to the empirical analysis result, this study verifies that perceived usefulness and satisfaction were determinants of continuous use intention in mobile easy Payment services. Expectation confirmation has been proved to be a positive predictor of satisfaction and perceived usefulness. Also, among the value factors, perceived ease was not a valid predictor of satisfaction, and the remaining factors were positive predictors of satisfaction.

본 논문에서는 OCR기술을 이용하여 나만의 소비패턴을 분석하는 어플을 제안한다. 현재 카드와 간편결제를 많이 쓰는 시대, 사람들은 소비 패턴을 쉽게 분석하고 알 수 없기 때문에 절약과 저축도 쉽게 못하고 있다. 따라서 OCR을 활용한 영수증 인식으로 소비 패턴을 분석하고 나의 소비 생활을 쉽게 알 수 있는 서비스를 통해 소비 문제가 개선될 것이라고 생각한다. 가계부의 핵심 기능은 수입/지출을 표기하는 것이다. 하지만 현재 상용 중인 소비 앱은 너무 많은 기능을 도입해 오히려 사용성이 떨어진다. 이를 해결하기 위해 복잡한 서비스는 빼고, 핵심 기능과 OCR 기능, 예산 관리, 포인트 제도, 카테고리별 지출 관리를 넣었다. 프로젝트의 대상은 평소 과도한 지출을 하는 사람과 자신의 소비를 기록하고 싶은 사람이며, 본 시스템에서 OCR을 이용해 소비시 발생하는 영수증을 인식하여 더욱 편리하게 입력할 수 있다. 또한, 비 계획적인 소비를 효율적으로 해결할 수 있으며, 포인트 제도를 이용해 사용자의 출석률 문제를 효율적으로 해결할 것으로 기대된다.

This study aimed to compare the systems of ticketing application programs of three major movie theaters, CGV, Megabox, Lotte Cinema, with each other and evaluate the usability, and find problems to figure out user experiences for more convenient mobile ticketing. Experimental subjects with experiences of using apps of the movie theaters were recruited; First, as a primary task, they reserved movie tickets with each of the movie theater apps; Second, they had in-depth interviews with questions based on the model of Creating Pleasurable Interfaces by Stephen Anderson. As a result, users preferred the composition with information in order in overall, in which ticketing process went smoothly. In particular, users were more satisfied with convenient payment applications. Therefore, as an improving way, it is required to design an interface for users to recognize at a glance and a payment system within an app, not to design separate payment system out of the app. I hope this study will help actively conduct researches to maximize the usability in a way to reserve movie tickets through smartphone apps.

사물인터넷 (IoT), 핀테크(Fintech) 등 새로운 기술의 등장으로 보안성에 대한 부분이 커지고 있다. 모든 사물이 인터넷과 연결되는 사물인터넷 기술로 인해 악성행위와의 접점이 크게 증가했으며, 핀테크(Fintech)는 전통적인 보안시스템의 개혁을 요구하고 있기 때문이다. 사물인터넷 환경에서 이루어지는 간편 인증 결제시스템이 발전함에 따라 다양한 보안위협요소가 발생할 것으로 예상한다. 접점의 증가로 인해 고객이 실수로 악성코드를 받게 될 가능성과 사물인터넷의 핵심 기능인 원격접속에 대한 위협이 대표적인 예라고 할 수 있다. 그러나 현재 고객의 단말을 강제로 통제할 수 있는 방법이 전무한 상황이고, 향후 서비스에서 필요한 고객정보수집과 활용에 대한 정책이 필요한 시점에서 발생할 수 있는 해킹 기법을 제안하고자 한다.
