The aim of this study is to find out what influences the user intention of a new system. The user is seen here as the key to acceptance of a mobile payment service, hence the focus on understanding their motivations and attitudes. To predict acceptance, Technology Acceptance Model (TAM) has been extensively used in information systems. This study is based on the belief that TAM needs to be expanded and customized to suit specific characteristics of mobile payments. A mobile payment research model consists of five mobile payment system characteristics: perceived ease of use, perceived usefulness, mobility, compatibility, security, subjective norm. The empirical results show particularly strong support for the effects of mobility and attitude of consumer. The study offers several implications for managers in regards to advertise and improve mobile payment solutions to increase intention of consumers to use these services.
