The statistical population consists of the customers who referred to branches of bank Saderat across Qazvin city, that sample size (385) was obtained using Cochran formula. To measure validity of questionnaire with referral to scholars, validity of questionnaire was confirmed through Lawshe's formula, and its reliability was obtained through Cronbach's alpha formula. The results of this study indicate that trust and risk factors from six different aspects affect initial acceptance of mobile banking. To investigate effects of research variables, methods of inferential statistics including SPSS and LISREL software have been used.
