Based on Technology Acceptance Model (TAM) study, the perceived ease of use is influences by the self-efficacy. According to Moores (2012), the extent to which the system user believes that they have capability to use the system is reflects to the self-efficacy. The self-efficacy can be measured by the opinion, the skills, and also by the objective ability. So from that situation, it can be conclude that the more skills and experience with the application people use, the more they believe they are able to cooperate with the system. Then, the less skills and experience with the application people use, the less they believe they are able to cooperate with.Moreover, according to Davis (1993) the definition of perceived ease of use is “the degree to which an individual trust that using a certain specific system can be free of physical and mental effort. The ability and the effort expectancy affects perceived ease of use based on the TAM’s research (Lee & Song, 2013; Venkatesh et al., 2003; Moqbel, 2012). Perceived ease of use exerts positive feedback on perceived usefulness. “Perceived ease of use is to have a powerful direct accoutrement on perceived usefulness, since all are being same which it becomes simple and easy to use in order to enlarged job performance for the user.” (cited in Davis, 1986: 26). There are two instruments to understand the elements of perceived ease of use by which it influences intention. Firstly, according to Davis et al. (1989) and Venkatesh (2000) perceived ease of use has direct and indirect consequences via perceived usefulness. Secondly, the users should defeat for acceptance, adoption and usage of a system because it is an initial hurdle. Besides that, Wu and Wang (2005) had studied that perceived ease of use effects behavioral intention to use indirectly and indirectly effects intention to use through perceived usefulness. In addition, Islam et al. (2013) was argue that perceived ease of use is not more important to understand the user intention to adopt a particular system, which contradicts to the previous studies of Mafe, Blas and Tavera-Mesi (2010). This result could change the depending on the research of context and the other factors.
