Factors Affecting the Use of Digital Banking: A Literature Review

In recent years, digital technology has brought major changes to financial services. These rapid changes have created both new opportunities and challenges for digital banking. This has encouraged researchers to study and investigate this phenomenon. Thus, this narrative review includes 35 peer-reviewed studies published between 2021 and 2026. It explores what motivates people from different countries and backgrounds to start using digital banking. The main factors are organised using several frameworks: Technology Acceptance Model (TAM), Unified Theory of Acceptance and Use of Technology (UTAUT), Task-Technology Fit (TTF), and Technology-Organization-Environment (TOE). These frameworks combine the key factors into six areas: trust and security; perceived usefulness and ease of use; customer experience and service quality; technological infrastructure and compatibility; demographic and socioeconomic factors; and institutional and regulatory influences. Thus, people are more likely to use digital banking if they trust it, find it easy to use, and believe it is safe. Age, education, and digital skills also affect adoption. Although digital banking is becoming more common, it still faces challenges such as privacy concerns, complex technology, limited digital infrastructure, and unclear regulations. This review highlights the main reasons people use financial technology and offers suggestions to make digital banking easier and more accessible.
