Although mobile computing is getting popular but shopping with mobile devices does not follow the trend. The fundamental reason is the transaction security. Following Model of Argument by Toulmin and Persuasion Principles by Cialdini, we proposed the Trust Transference Facilitator (TTF) to convince users that the mobile shopping is secure. Similar mechanism has been proven to be effective and this study provides evidence that such mechanism can be transferred to the mobile environment. We found that authority+contrast+scarcity mechanism was the most effective way to convince users that the transaction is secure.
