One of the most important techniques for development of internet banking is to encourage people to do their daily banking transactions through internet facilities. In this paper, we present an empirical study to find out whether perceived ease of use, perceived usefulness as well as trust could influence on internet banking. The proposed study was implemented in one of Iranian banks in city of Tehran, Iran using structural equation modeling. Cronbach alpha has been calculated as 0.90, which validates the overall questionnaire. Using structural equation modeling, the survey has concluded that perceived ease of use (B=0.18, p-value=0.000), perceived usefulness (B=0.24, p-value=0.000) and trust (B=0.55, p-value=0.000) had positive and meaningful impact on internet banking.
