Factors affecting the adoption of Internet banking in Tunisia: An integration theory of acceptance model and theory of planned behavior

Abstract
This paper examines empirically the factors that affect the adoption of Internet banking by Tunisian bank customers. As base model, we use the technology acceptance model (TAM) and theory of planned behavior (TPB). The model employs security and privacy, self efficacy, government support, and technology support, in addition to perceived usefulness, perceived ease of use, attitude, social norm, perceived behavior control and intention to use Internet banking. Structural equation modeling is employed to examine the inter-correlations among the proposed constructs. A survey involving a total of 284 respondents is conducted and confirmatory factor analysis was used to determine the measurement efficacies. Theoretically, this study confirms the applicability of the TAM model and TPB in predicting Internet banking adoption by Tunisian bank customers. The results allow banks' decision makers to develop strategies that can encourage the adoption of Internet banking. Banks should improve the security and privacy to protect consumers' personal and financial information, which will increase the trust of users. Government should also play a role to support bank industry by having a clear and solid law on this will ensure that customers are more confident for using Internet banking, ensuring a better Internet infrastructure and helps them to encourage users to use Internet banking. Lastly, Tunisian Banks should focus on those clients who already have a home PC, access Internet and more educated and younger since they are the most likely to adopt Internet banking.
