Purpose Financial inclusion remains a persistent issue in developing nations, where access to formal financial services is often limited. The propagation of Fintech services offers a transformative pathway to bridge these gaps and empower underserved populations. This study aims to investigate the key factors of Fintech adoption in developing nations. Design/methodology/approach The technology acceptance model (TAM) framework including Perceived Ease of Use (PEU), Perceived Usefulness (PU) and Social Influence (SI). Furthermore, this model was expanded to include Financial Literacy (FL) as one of the key determinants of fintech adoption in developing nations, like India. Findings The findings reveal that FL plays a significant role in effective engagement with Fintech, while PEU and SI significantly enhance intention to adopt fintech. PU also emerged as a critical driver of fintech adoption among low-income groups, especially for first-time users of financial services. This study emphasises that targeted interventions to improve financial literacy and foster trust in Fintech services is necessary. By addressing barriers in fintech adoption, Fintech can unlock its potential as a catalyst for financial inclusion, fostering equitable economic growth and reducing inequalities in developing nations. Originality/value This study examines factors that determine fintech adoption in emerging economies. The TAM framework was expanded to include financial literacy.
