In today’s digital age, financial technology (fintech) innovations are revolutionizing the way individuals and businesses manage financial transactions and services. As more individuals rely on digital platforms for financial management, understanding the psychological and cognitive factors that influence the adoption of fintech becomes essential. A key aspect of this study is the incorporation of IT-mindfulness, a concept derived from mindfulness research but adapted to reflect how users engage with technology. This study employs the Technology Acceptance Model (TAM) to explore the determinants of fintech adoption. This study extends TAM by incorporating IT-mindfulness as a precursor to these traditional determinants, hypothesizing that users who exhibit higher levels of IT-mindfulness are more likely to perceive fintech platforms as easy to use and useful. Moreover, this study introduces digital technology self-efficacy and financial literacy as key variables in understanding fintech adoption. This comprehensive model aims to provide a deeper understanding of how cognitive factors like IT-mindfulness interact with traditional TAM variables and personal competencies to influence users' fintech adoption behaviors.
