The user interface design of mobile financial applications based on the E-S-QUAL model

The intersection of FinTech and user interface (UI) design plays a critical role in shaping consumer trust and promoting the adoption of financial technologies. Recent studies have shown that UI design significantly impacts customer trust, perceptions of data security, and the overall user experience in FinTech applications. Additionally, the rapid adoption of FinTech solutions, accelerated by the COVID-19 pandemic, highlights the growing need for seamless and secure digital banking alternatives. However, despite these advancements, there remains a gap in how financial institutions design UIs that effectively meet user expectations while addressing key service quality dimensions. This study addresses this gap by applying the E-S-QUAL model to mobile financial applications' UI design. The E-S-QUAL model, with its focus on efficiency, system availability, fulfilment, and privacy, provides a structured approach to improving user satisfaction and trust. By integrating these dimensions, this research aims to develop a user-centric UI that aligns more closely with the diverse needs and expectations of FinTech users. Findings from this study will offer valuable insights for FinTech developers, contributing to the design of more efficient and trustworthy mobile financial applications.
