What motivates users to keep using social mobile payments?

Due to the rapid diffusion of social mobile payment (SMP), the current research explores the post-adoption behavior of SMP users. It proposes a research model to determine the core predictors of users' continuance intentions to use SMPs. Through the analysis of survey data from South Korea, it indicates that satisfaction strongly and positively affects users' continuance intentions. Moreover, satisfaction is influenced by perceived usefulness (PU), security, and enjoyment. Interestingly, although perceived ease of use (PEU) does not directly affect satisfaction, it can indirectly influence satisfaction via users' PU and perceived enjoyment. Furthermore, perceived ubiquity has strong effects on users' PU and PEU. The study also discusses meaningful implications, and provides suggestions for future studies.
