Digital banking has emerged as a pivotal force in enhancing financial inclusion by providing access to banking services for underserved populations, particularly in developing economies. This paper explores the impact of digital banking innovations, including mobile banking, internet banking, and fin tech applications, on improving access to financial services. The study employs a comparative analysis between developed and developing countries, examining how digital banking solutions are deployed, the challenges faced in each region, and their effectiveness in reaching the unbanked and under banked populations. By drawing from case studies, data from financial institutions, and interviews with banking professionals, this research highlights the critical role of digital banking in bridging the financial inclusion gap. It also identifies key success factors such as technological infrastructure, regulatory frameworks, and digital literacy. The paper concludes with recommendations for policymakers and banking institutions to optimize the use of digital banking platforms for financial inclusion, promoting economic growth and social equity across different regions.
