This research study aims to evaluate the factors that influence digital payment methods and customers' behaviour in the age of e-commerce, with a focus on mobile payment. The study used non-probability sampling methods and created a new conceptual model based on constructs from literature, which was then empirically evaluated using statistical techniques. The findings of the research indicate that perceived usefulness, perceived Ease of use, perceived trustworthiness, subjective norms, attitude, and intention are the factors that influence the decision to adopt digital payment methods. The study focuses primarily on mobile payment, but its findings can also be applied to other payment options. This study is vital for academicians and researchers as it provides empirical evidence of the factors influencing customers' adoption of digital payment methods. It also gives Communications Corporation a foundation to build mobile payment methods and improve customer adoption.
