Fintech has emerged as a transformative strategy offering convenient, timely, high-quality, and low-cost financial services to individuals and enterprises. However, as cyber threats increase, so does the perception of risk. The study attempts to address this risk perception and other background factors to examine the behaviour of bank customers. The proposed framework incorporates the theory of planned behaviour and the technological acceptance model to predict behaviour. Using convenience sampling, we ultimately selected 390 bank customers as our final respondents. The study employed correlation, regression, mediation, and moderation analysis to test the hypothesis. The findings revealed that innovation, perceived usefulness, ease of use, and trust significantly positively impact attitudes towards fintech decisions. This study has implications for policymakers, banking service providers, and governments in establishing strategies to mitigate the perceived risk and improve the usefulness of services offered by FinTech.
