This research is to explore the development of electronic payment systems in Thailand. The evolution of retail industry and electronic payment systems in Taiwan are studied and investigated as for the development guidance for the retail industry and electronic payment systems in Thailand.

Additionally, the technology of the Internet and mobile technologies also plays important roles to lead the growth of online retail sales and electronic payment systems which provide a better choice for customers who value convenience.
The exploratory research and the comparison between Thailand and Taiwan were conducted in this research study. The comparative experiments were also performed to indicate the differences and similarities of the evolution of electronic payments between Thailand and Taiwan. The experimental results suggest that the electronic payment systems (including electronic wallet) in Thailand will be increased in the future; in the estimation of thirty years, a number of electronic payment systems implemented in Thailand will be the same as Taiwan's current situation in using such systems. However, the government's support is also the key to improve the development and expansion of electronic payment systems on the retail industry in Thailand.
