The purpose of this research is to evaluate the function that Perceived Trust plays as a mediator in the adoption of biometric as a service (BaaS) among customers of Jordanian telecommunications. Through the utilization of a quantitative survey that was administered to four hundred employees, an investigation was carried out to investigate the ways in which organizational elements (Organizational Development and Training and Skill Development) and technological aspects (Compatibility, Complexity, and Trialability) influence BaaS User Acceptance. As a result of the data that we acquired, the significance of Corporate Culture, Training, and Skill Development was brought to light. According to the findings of a study, User Acceptance may be increased via the implementation of business culture and appropriate training. Compatibility emerged as a significant technical challenge that had an influence on adoption, underlining the significance of ensuring that there is a smooth interaction with those that are already in place. The links between organizational and technological characteristics and User Acceptance were also shown to be mediated by Perceived Trust in BaaS, a crucial mediating variable. Surprisingly, there was no significant effect of trialability on either acceptance or trust. Within the specific context of Jordanian telecommunications firms, our findings contribute to a better understanding of the complex interplay between organizational and technological elements that plays a role in molding workers’ impressions of BaaS. This study highlights the importance of trust-building methods in the effective integration of this technology within the Jordanian telecommunications sector. It also proposes practical implications for companies who are working to increase the use of BaaS. In addition, it also highlights the determinants of BaaS adoption by the Jordanian telecommunications firms.
