Various advancements in digital payment options have been developed as tools for transforming financially excluded communities across the globe. This work analyses the role those digital payments have played in extending financial services provision in developing countries, through a detailed evaluation of adoption factors, challenges faced and outcomes. Based on the empirical experience within the digital payment’s environment in India with respect to the use of Unified Payment Interface and RuPay cards, the study adopts an integrative quantitative and qualitative research strategy by analysing both transaction data and various stakeholder assessments. Results of the study show that there was almost 11 times increase in the adoption of digital payments in the period 2021-2025, especially as far as transaction volumes using UPI are concerned, accounting for almost 80% of total digital payments. Ease of use, trust, security, and digital financial literacy were found to be significant determinants of the use of these innovations.
