Abstract
Although millions of dollars have been spent on building mobile banking systems, reports
on mobile banking show that potential users may not be using the systems, despite their
availability. Thus, research is needed to identify the factors determining users’ acceptance of
mobile banking. While there has been considerable research on the technology acceptance
model (TAM) that predicts whether individuals will accept and voluntarily use information
systems, limitations of the TAM include the omission of an important trust-based construct in
the context of electronic/mobile commerce, and the assumption that there are no barriers
preventing an individual from using an IS if he or she chooses to do so. Based on literature
relating to the theory of planned behavior (TPB) and the TAM, this study extends the applicability
of the TAM in a mobile banking context, by adding one trust-based construct
(‘‘perceived credibility’’) and two resource-based constructs (‘‘perceived self-efficacy’’ and
‘‘perceived financial cost’’) to the model, while paying careful attention to the placing of these
constructs in the TAM’s existing nomological structure. Data collected from 180 users in
Taiwan were tested against the extended TAM, using the structural equation modeling approach.
The results strongly support the extended TAM in predicting users’ intentions to
adopt mobile banking. Several implications for IT/IS acceptance research and mobile banking
management practices are discussed.
