The present research examines online banking services, and it challenges the prevailing assumptions underlying the nomological validity of the Technology Acceptance Model (TAM). Results from 594 Taiwan respondents support a negative relationship between sub-constructs of consumers’ risk propensity and ensuing online banking services (OBS) engagement. The most important contribution is the strong empirical support that both consumers’ positive impact of perceived ease of use and perceived usefulness are positively related to the adoption of OBS. Furthermore, the results reveal that the assumptive impact of perceived risk construct is negatively associated with OBS adoption. The diminished impact of perceived risk explicitly challenges the predominant underpinnings of the TAM framework. In addition, findings reveal that the perceived risk factor consists of five underlying dimensions: financial risk, performance risk, time risk, psychological risk, and privacy risk.
