Financial technology (Fintech) services using emerging technology such as the Internet of Things (IoT) is becoming more prevalent. The recent proliferation of the mobile payment sector led by innovative mobile Fintech payment services such as Apple Pay and Samsung Pay is the most important and fastest growing Fintech services from consumers’ perspective. Although businesses have been making efforts to spread the use of the services, security is crucial in the diffusion of the services. Despite the importance, the role of perceived security in continuous intention to use mobile, Fintech services has not yet been investigated in depth. Thus, this study investigates the relationships between perceived security, knowledge regarding the services, confirmation, perceived usefulness, and satisfaction. We propose a research model using an extended post-acceptance model (EPAM) as a theoretical framework in the context of Fintech services. We then validate the model using the data collected from the service users. The analyzed results show that knowledge and perceived security in mobile Fintech services have a significant influence on users’ confirmation and perceived usefulness. However, perceived security does not directly influence users’ satisfaction and continual intention to use. We further find significant relationships among confirmation, perceived usefulness, satisfaction, and continual intention to use of the services. We discuss theoretical and practical contributions of the study.
