Since 2016, the Indian market has been responsible for the majority of the UPI platform's adoption, which is also referred to as the Unified Payment Interface (often known simply as UPI). This study's objective is to discover how the Unified Payments Interface (UPI) in India is affecting the underserved people there in terms of their level of economic development, access to banking services, and financial literacy. In order to demonstrate the existence of the connection, a structural equation modeling-based route analysis of the significant component is carried out. In order to collect the information required for the inquiry, a questionnaire using an interval scale was utilised. It has been discovered that people's acquaintance with personal finance may be affected as a result of the UPI. There is a negative correlation between the tempo of economic augmentation and the percentage of the population that is financially literate and, as a result, actively participates in the financial system. The reason for this is that having a strong understanding of personal finance inspires more people to make use of the monetary system. When monetary means are included into either of these linkages, the quality of either or both of those ties is improved. The most significant outcome of the research was that UPI has a variety of beneficial benefits on society. This has a knock-on effect of increasing financial literacy, which in turn assists people with lower incomes in bettering their financial situation and participating in the financial system. As a consequence of this, the findings of this study might have some influence on how the UPI policy is established in the years to come. In prior research, a correlation between the UPI and any of the aforementioned indices of the involvement of economically excluded groups was not discovered to exist.
