This study sought to improve the mobile easy payment services available in Korea by conducting a comparison analysis of Kakaopay, the front-runner of the mobile easy payment services in Korea's FinTech industry, compared to Naverpay, the relative newcomer in the industry. The services were compared by analysing users' experience. First, a literature review on the theoretical background of the FinTech and its characteristics was performed. Secondly, a survey created by reframing the six elements of the "Creating Pleasurable interfaces Model" by Stephen Anderson was conducted. In result, Kakaopay showed limited applicability caused by the lack of affiliated stores and it also showed the lack of reliability due to errors and cancellations related to the payments. It was shown that Naverpay also needs to make an effort to improve the reliability by minimizing errors in the use of the program and payments. This current study aimed to contribute as a resource which can be used, in the future, to improve the users' experience in FinTech services offered in Korea and also to invigorate the Fintech industry.

The blog posts mentioning Kakao Pay and Alipay were collected, and keyword analysis was performed to investigate differences in consumers' responses to Kakao Pay and Alipay on social media. The frequency of keywords for each part of speech and the frequency of co-occurred words mentioned in one sentence were analyzed. Specifically, common words that appear in both Kakao Pay and Alipay blogs were extracted. The cooccurred words were analyzed to examine how different reactions were made on the same subject. As a result of the analysis, there were concerns among consumers about the trust of Kakao Pay and Alipay's benefits. For a mobile payment service to become competitive, it is necessary to add various additional services or solve security problems.

본 논문에서는 국내 모바일 간편 결제 서비스 카카오페이(KakaoPay)의 보안취약점을 분석한다. 이를 위해, 본 연구에서는 모바일 간편 결제 서비스 키패드의 터치 좌표값을 추출하는 키로거 앱(key logger application)을 개발하였다. 키로거 앱을 이용해 사용자가 카카오페이 서비스의 비밀번호를 누를 때 비밀번호가 출력되는 화면 좌표값을 알아내고, 확률분석기법을 통해 추출한 화면 좌표값으로 결제용 비밀번호를 유추해냄으로써, 카카오페이 서비스의 보안 취약점을 도출하였다.

This study identifies possible determinants that may have influences on the switching behavior from the current payment system of credit or check cards to the easy payment service based on push-pulling-mooring model. And this research empirically tests how those determinants affect switching intention to the easy payment service. The moderating effect of policy expectation is also taken into account. The findings show switching intention to the easy payment service is influenced by the followings: dissatisfaction with the current payment system as a pushing factor, perceived easy of use and trust in easy payment service as pulling factors, and affective/cognitive inertia and unfavorable subjective norm as mooring factors. The results also show that moderating effect of policy expectation exists in the relationship between perceived ubiquitousness and switching intention.

본 논문은 환경 보호와 도시 이동성 최적화를 위한 효율적인 운행 수단인 카풀(Carpool)을 제안한다. 카풀은 도로의 차량 수를 감소시켜 도로 교통 혼잡과 주차 공간 필요성을 줄이는 효과를 가져온다. 또한 카풀은 운전자 개인이 부담해야 할 운행 비용을 여러 명이 함께 부담하여 경제적 부담을 감소시킨다. 본 프로젝트에서는 실시간 GPS를 이용하여 이용자의 실시간 위치를 파악하여 이용의 편의성과 안전성을 향상시켰다. 카카오페이 API를 활용한 선 결제 시스템, 파이어 베이스를 이용한 채팅 기능, 웹 소켓을 활용한 실시간 알람 기능을 이용하여 더욱 안전한 이용이 가능하도록 하였다. 웹 환경에서도 관리자가 회원들의 관리를 보다 효율적으로 할 수 있게 하였다. 본 논문에서는 기존의 카풀 서비스의 문제점을 제시하고 그에 대한 해결 방안을 구현하여 안전한 카플 서비스를 지원한다.

This research aims to evaluate how each generation experiences easy payment services. Recently, the easy payment service business has been on an upward trajectory and pin-tech companies have introduced various types of products. In this regard, it becomes crucial to understand differences among generations in terms of using those services due to their accessibility and serviceability. Based on the statistical analysis of surveys and in-depth interviews based on Peter Morville's Honeycomb model, this study suggests four ways to improve this payment service. The analysis indicates that those who are older tend to use easy payment services provided by their credit card companies or services which they frequently have already used. Findings of this analysis are expected to find the relationship between ages and payment applications.
