The Diffusion and Adoption of Electronic Payment Systems in Bangkok

This article aims to study the diffusion and adoption of electronic payment systems in Bangkok, Thailand. This study is a cross-sectional survey of 394 respondents who lived in Bangkok. This research employs Pearson's correlation and structural equation modeling (SEM) to answer two research questions: 1) How do the socio-economic classes of people show differences in the use of e-payment systems? and 2) What are significant factors driving customers to use e-payment systems? The findings show that user behavior has a positive correlation with personal income. Higher-income people tend to use electronic payment systems more than lower-income people. There is no relationship between areas and use behavior. Moreover, the research shows that adoption readiness, income, and internet banking positively influence use behavior significantly, while electronic money shows a significant negative relationship with use behavior. Education and age indirectly influence use behavior via personal income. The authors also addressed both theoretical and practical implications.
