This paper is trying to examine if we can persuade users to trust mobile banking system by using persuasive message which includes information about privacy and security policy of mobile banking system. In order to achieve this aim, we will apply Elaboration Likelihood Model (ELM).

ELM is one of the most widely used theoretical frameworks to explain how attitude is affected by persuasive messages. It is one of the popular persuasive message models (Petty and Cacioppo, 1986). According to ELM, there are two different routes of influence which caused the attitude change among individuals. These two routes are called the central route and the peripheral route (Petty et al., 1981). A person who depends on the central route needs to think judgmentally about arguments in an informational message before making an informed judgment about the target behavior (Bhattacherjee and Sanford, 2006). So, attitude change arises from a persons consideration of information that reflects what that person feels are the true merits of a certain position (Petty and Cacioppo, 1984). Peripheral cues are related to information about the message like message source (Bhattacherjee and Sanford, 2006). Contrary to the central route, peripheral route related to meta- information about the message like message source (Bhattacherjee and Sanford, 2006). It includes the number of messages, number of message sources, source likeability, and source credibility.)
