The Bank of Thailand (BOT) conducted a survey on electronic payment (e-payment) behavior among small and medium-sized enterprises (SMEs) across seven industry sectors, taking into account dimensions such as company size, location, and payment activities. The BOT has applied key insights from the survey to strengthen payment system supervision in terms of system efficiency and security, as well as to set directions and policies for payment system development and to increase businesses' knowledge, understanding, and confidence in service security.
