The impact of the coronavirus outbreak on the global economy will certainly be profound, long-term, and perhaps worse for some vulnerable countries. The epidemic of this virus is one of the biggest shocks in the current generation. Because the daily economic activities of many nations have changed on an unprecedented scale with an area of about 210 countries. Although the spread of the coronavirus has created unpleasant conditions for the people of the world, in some cases it has been able to turn threats into opportunities. The development of some services, including remote and digital services in the country, despite significant and extensive planning, has not made significant progress, but the spread of the virus has accelerated the implementation process and the acceptance of these plans by the people. In this study, the effect of coronavirus outbreak as an interfering element in the acceptance of digital banking has been studied. By studying the theoretical foundations and interviewing experts, the factors affecting the acceptance and development of digital banking in Iran were identified and by identifying the effects of corona outbreak in the acceptance of offline services, the research model was simulated using systems dynamics. The simulation results showed that with the implementation of the policy of reducing the number of branches, incentive policies of the bank and increasing the bank budget in the Information technology sector, the acceptance and use of digital technologies by customers will increase and the prevalence of Corona virus by increasing the acceptance rate as a factor. Positively works in the acceptance and development of digital banking.
