This study investigates the adoption and use of Point-of-Sale (POS) services in Ekiti State. It aims to identify the key factors driving POS adoption, assess the impact of POS usage on local economic activities, examine the relationships among latent variables such as adoption determinants, operational efficiency and user satisfaction, and investigate the challenges associated with using or operating POS services. The findings provide insights into how POS services influence financial behaviour, economic outcomes, and operational constraints in the state. Using a cross-sectional design and data collected through structured questionnaire distributed via Google Forms, the research analysed the determinants, challenges, and socioeconomic implications of POS service usage among traders, civil servants, and micro-entrepreneurs. Descriptive and inferential analyses were conducted using Structural Equation Modelling (SEM) in WarpPLS 8.0. Results reveal that convenience, speed and access to cashless transactions significantly influence POS adoption. Despite challenges such as network failures, delayed transaction reversals and poor service quality, POS usage has positively enhanced trade, financial inclusion and local business efficiency. The study, as a matter of policy statement applicable to this study, the dominance of convenience and accessibility factors in Ado and Ikere-Ekiti underscores the need for financial regulators and service providers (e.g., MTN, GLO, etc.) to enhance POS reliability and geographical coverage, with an extension to the rural or under-served communities.
