Financial Technology (FinTech) has transformed the global financial services industry by integrating advanced digital technologies with traditional financial systems. This study examines how service innovation in FinTech influences user adoption behavior. Innovations such as digital payments, mobile banking, artificial intelligence, automated financial services, and real-time transactions have significantly improved accessibility, convenience, and efficiency in financial services. Primary data for the study was collected from 154 respondents through a structured questionnaire. Statistical tools such as percentage analysis and correlation analysis were used to interpret the data. The findings reveal that young users, particularly students and undergraduates, represent the largest group of FinTech users. Digital payment platforms and UPI-based applications are the most frequently used services. The study also highlights that innovative features such as digital KYC, instant onboarding, and automation positively influence user adoption. However, challenges such as poor internet connectivity, security risks, and fear of financial loss remain barriers to wider adoption. The study concludes that continuous service innovation, improved security mechanisms, and digital literacy initiatives are essential for enhancing user trust and encouraging greater adoption of FinTech services.
