Payments in Digitalization Era: Factors Influencing Digital Payments on F&B Delivery Applications in Phnom Penh

Abstract

The rapid growth of digital payment systems in emerging markets has reshaped consumer behavior patterns, particularly in cash-dependent economies like Cambodia. This study investigates the determinants of digital payment adoption within Cambodia’s food and beverage (F&B) delivery application. This research reviews the Technology Acceptance Model (TAM) and Unified Theory of Acceptance and Use of Technology (UTAUT). From an analysis of 329 samples in Phnom Penh, the results reveal that perceived usefulness, ease of use, social influence, government support, and service quality significantly drive adoption. Notably, security and trust, which are often emphasized in prior literature, exerted negligible direct effects, suggesting these factors are now perceived as basic expectations. The findings identify the significant role of user-friendly interfaces, peer networks, and policy frameworks in accelerating cashless transitions. The study recommends simpler user interfaces, using social media to connect with users, and strong collaborations with governments and businesses to speed up the shift to digital payment systems. Theoretically, this research also contributes to technology adoption theories by contextualizing their applicability in emerging economies and offers actionable insights for stakeholders navigating Cambodia’s evolving digital landscape.
