Customers' intentions to use mobile payment service: a comparative study of payment system types

With the development of mobile technology, mobile payment services are some of the fastest growing transaction systems in the industry. However, studies of mobile payment systems have focused on retailing settings; few studies have examined them in the service setting. Thus, this research explores the effects of mobile payment system-related characteristics (i.e. perceived ubiquity, perceived security, perceived ease of use, perceived cost) on customers' intentions to use mobile payments in the restaurant setting. An online survey (n = 370 ⁣) was conducted in the United States. The data are analyzed by partial least squared-structured equation modeling. The study results demonstrate that restaurant customers' intentions to use mobile payment are largely determined by perceived usefulness, trust, and attitude. Among them, perceived usefulness is the most important factor for predicting customers' intentions across different types of mobile payment systems (i.e. mobile proximity payment, mobile peer-to-peer payment, mobile in-app payment). These findings have useful theoretical and practical implications for better understanding customers' mobile payment usage behavior.
