Dominant factors affecting the Mobile Payment Service in Korea : Applying UTAUT model for Korean young people

The mobile easy payment service will accelerate with the expansion of O2O (offline-to-online or online-to-offline) market. As the use of smartphones became widespread, the mobile payment service market is also increasingly growing. This study focuses on the new and strong relative advantage of using the mobile simple payment service which can be accessible to the service among the fin tech industry from the viewpoint of the financial consumer and the influence of acceptance as well as the spread of the fin tech financial service. This study also focuses on the perceived risk of high school students and individual differences. We propose a research model on the effect of consumer's perceived usefulness, relative advantage and self-efficacy on the intention of simple payment using mobile payment system based on Integrated Technology Acceptance Theory(UTAUT). This study investigates whether factors such as perceived risk and consumer innovation tendency, which are likely to be psychological constraints, affect the intention to use the simple payment system. In this study, we examined the factors having a significant effect on users' continuous intention to use mobile easy payment as suggested by Venkatesh(2003). We conclude that future research is necessary to see if the mobile easy payment continues to spread to non-users.
