Technological Innovation in FinTech and Its Role in Advancing Financial Inclusion: A Comprehensive Literature Review

Abstract

Financial technology (FinTech) has significantly transformed the structure and delivery of modern financial services by introducing innovative digital solutions that improve accessibility, affordability, transparency, and operational efficiency within financial systems. Over the last decade, technological advancement has accelerated the digitalization of banking, lending, payments, investment management, and insurance services across developed and developing economies. Innovations such as mobile banking, digital wallets, blockchain systems, artificial intelligence, cloud computing, and big data analytics have changed the way individuals and businesses interact with financial institutions and financial markets (Arora, 2024; Chang et al., 2024). that enhance access to financial services, especially for underserved and financially excluded populations. This literature review critically examines the relationship between technological innovation in FinTech and financial inclusion by synthesizing contemporary academic and policy-oriented literature. The review explores major FinTech technologies including digital payments, blockchain, artificial intelligence, big data analytics, mobile banking, cloud computing, and open banking systems. It further evaluates theoretical foundations such as the Technology Acceptance Model (TAM), Unified Theory of Acceptance and Use of Technology (UTAUT), Innovation Diffusion Theory, and the Technology–Organization–Environment (TOE) framework. The review identifies how FinTech innovations improve accessibility, affordability, efficiency, and convenience of financial services while simultaneously creating new challenges related to regulation, cyber security, digital literacy, consumer protection, and digital inequality. The findings reveal that FinTech significantly contributes to financial inclusion through digital payment systems, mobile money, digital lending, peer-to-peer financing, crowd funding, and AI-driven credit scoring models. However, the benefits remain uneven due to socioeconomic, geographic, gender, and technological disparities. The study adopts a systematic literature review methodology by analyzing peer-reviewed journal articles, policy reports, conference papers, and institutional publications related to FinTech and financial inclusion. Findings suggest that supportive regulatory frameworks, improved digital infrastructure, financial literacy programs, and collaborative ecosystems among governments, financial institutions, and technology firms are essential to maximize inclusive financial outcomes.
