The objective of this research is to find out the acceptance of sales drivers in logistic industry to use the smartphone in their work. This research uses two methods to collect data: survey and experiment. This research integrates technology acceptance model (TAM) (Davis, 1989), self-efficacy (Bandura, 1982, 1986), and innovation diffusion theory (IDT) (Rogers, 1962) into the research model to find out the factors of sales drivers in logistic industry accepting the smartphone. This experiment is focused on three user groups: the employees of a business that implements smartphone usage, the employees of businesses that do not use smartphone, and the students that are currently studying at a department of transportation and communication management. The results will help us understand whether this technology should be integrated into the traditional logistics system, and get to know the pros and cons of this idea.
