Digital Payment Technology and Financial Inclusion

This study examines the impact of digital payment technologies on financial inclusion in Nigeria, focusing on Automated Teller Machine (ATM) transactions, Point-of-Sale(POS) transactions, Web Pay transactions, and mobile payments. Despite significant advancements in digital payment infrastructure, approximately 40%of adult Nigerians remain financially excluded, revealing persistent challenges inachieving universal access to financial services. The research addresses this gap by empirically investigating how different digital payment channels contribute to broadening financial participation in the formal economy. The study adopts an Ex-Post-Factoresearch design, utilizing quarterly time series data spanning from2009Q1to2023Q4,yielding 60 observations. Secondary data were obtained from the Central Bank of Nigeria Statistical Bulletin and the Nigeria Inter-Bank Settlement System. Financial inclusion was operationalized as total savings as a ratio of GDP, while independent variables captured transaction volumes across the four digital payment channels. The analytical framework employed Augmented Dickey-Fuller unit root tests, Johansenco integration analysis, and the Autoregressive Distributed Lag (ARDL) bounds testing approach to examine both short-run dynamics and long-run equilibrium relationships. Results indicate that only mobile payment transaction volume demonstrates a statistically significant positive effect on financial inclusioninNigeria.ATM, POS, and Web Pay transaction volumes show no significant impact, attributed to infrastructure constraints, urban concentration of services, digital literacy gaps, and limited accessibility in rural areas. The superior performance of mobile payments stems from widespread mobile phone penetration, USSD technology compatibility with basic phones, minimal entry barriers, and distributed agent networks reaching underserved populations. The study concludes that mobile payments represent the most effective digital channel for advancing financial inclusion inNigeria.Recommendations emphasize prioritizing mobile payment infrastructure development,addressing electricity and telecommunications constraints, enhancing financial and digital literacy programs, reforming regulatory frameworks, including tiered KYC requirements, expanding agent networks into rural areas, and leveraging mobile platforms for government-to-person payments. Policymakers should adopt comprehensive strategies integrating supportive ecosystems that enable access, build capability, and foster trust to maximize mobile payments' potential in achieving sustainable financial inclusion.
