We argue that there are ten factors impacting on the trust, including personal trust propensity, personal perceived risk, bank’s reputation, bank’s scale, perceived usefulness of web, perceived ease of using the web, the quality of web’ information, transaction institution, network security and the other people’s attitudes. We design the customers’ trust evaluation indicators according to these factors and test the effectiveness of them. Then, we build a trust model with fuzzy comprehensive evaluation method. Finally, we conduct an empirical study on the model using the customers’ data.
