This paper empirically explores customers’ trust in Internet banking based on a research model with several constructs such as structural assurance, perceived bank reputation, perceived website quality, and disposition to trust. The results suggest that these constructs significantly influence trusting beliefs and customers’ willingness to use Internet banking, which in turn have a positively impact on the establishment of customers’ trust in Internet banking. Trust building should strengthen customers’ confidence in Internet banking and facilitate the development of sustainable Internet banking services.
