The world financial market is experiencing a technological revolution like never before that is fuelled by Unified Payments Interface (UPI), blockchain and artificial intelligence (AI). It is particularly significant in India: UPI has already conducted more than 131 billion transactions (200 trillion rupees) in FY 202425 alone and AI-based fraud detection and blockchain-based smart contracts are transforming the very core of the banking processes. The present paper provides empirical studies of adoption trends, user satisfaction, and structural issues of fintech technologies with a survey consisting of 50 participants via an intersect survey of urban and semi-urban India. Descriptive analysis, chi-square, and Likert-scale composite scoring reveal that 76 percent of the respondents pay with digital systems frequently, 68 percent of them feel that technology has made them more financially safe, and 62 percent enjoy cybersecurity threats and 58 percent digital literacy gaps as the ongoing challenges. Statistically analysed results showed significant correlations between the age, the degree of digital familiarity, and trust in fintech platforms (p < 0.05). The paper highlights some of the most important gaps in the research, specifically those associated with the role of the government in regulation and adoption of fintech by SMEs, and suggests a realistic policy framework that can be used to contribute to the inclusive adoption of fintech in developing economies.
