The development of Indian digital payment systems has been attributed in large part to digitalization, the introduction of new payment choices, and greater customer awareness. Most research investigations came to contradictory conclusions that need to be looked into. As a result, the research study selected 200 customers from the Thoothukudi District using a practical sampling technique. It was done using the t-test, f-test, ANOVA, and post-hoc test. In terms of socio-economic characteristics, the study found that only education had a positive relationship with environmental indicators. It also showed that customers preferred digital payments due to their ease, time savings, easy use, safety, and security.
