The emergence of online payment has completely changed how consumers and businesses interact on a global scale. Online payment refers to payment that are made for goods or services that are ordered online or offline and are initiated using internet. Understanding how digital financial services affect consumer decision-making is becoming more and more crucial, especially in developing nations like Nepal. In Nepal, Nepal Rastra Bank (NRB) is dedicated to the security and effectiveness of Nepal's National Payments System (NPS) in recognition that payment systems are an essential component of every nation's financial system and are essential for its soundness, as well as for the execution of monetary policy and the growth of capital markets. The rise in e-commerce and mobile commerce activities in recent years can be attributed to the widespread use of mobile devices and internet connectivity. Research has indicated that the incorporation of electronic payment systems might have a noteworthy impact on consumer conduct, providing convenience and effectiveness during transactions (Jakhiya et al., 2020). Given the dynamic nature of Nepal's digital infrastructure, analyzing the differences in the adoption of these technologies and the ensuing shifts in customer behaviour might yield insightful information.
