This study is conducted to investigate the impact levels of determinants on customers' decision to use payment services via mobile devices in Hanoi, Vietnam. Data were collected from a survey of people living in Hanoi city of Vietnam who may or not use mobile payment services. Based on the theory of technology acceptance and use (UTAUT) developed, we design a research model with six determinants including expected efficiency, effort expectations, social impact, safety and security, perceived costs and supplier reputation. The results show that determinants of expected efficiency, expected effort, social impact, safety and security and supplier reputation (except perceived costs) had positive impacts on the decision of customer. However, the degree and order of impact varies between two groups of unused and already used customers. In particular, the determinants of effort of expectation, safety and security, reputation of suppliers had the strongest impacts on the decisions of customers in both groups in using payment services through mobile device. Based on the findings, we give suggestions for managers and service providers in developing this kind of service in Hanoi, Vietnam as a case study for emerging countries.
