Digital Trust and Checkout Choices: Empirical Evidence on Online Consumer Behavior in Asia

Abstract

This paper examines the role of digital trust, perceived usefulness, social influence, logistics reliability, and checkout option (cash-on-delivery and digital payment) in online consumer behavior across four Asian markets (Bangladesh, India, Indonesia, and Vietnam) within an emerging cyber-physical systems (CPS) environment. Cyber-physical commerce integrates computational and physical systems—such as smart devices, embedded sensors, and real-time tracking—into e-commerce platforms, thereby transforming how users perceive risk, trust, and continuity of use. Information systems theories (TAM/UTAUT) and consumer trust literature guided a cross-sectional survey (N = 2,412), analyzed via PLS-SEM with multi-group analysis. We find that the strongest predictors of purchase intention are trust and logistics reliability, while perceived usefulness is the major predictor of continuance intention. Checkout choice has a dual nature: cash-on-delivery is perceived to reduce payment risk and reinforce the trust–intention relationship in low card-penetration cohorts, whereas digital payment strengthens the usefulness–continuance linkage in higher-adoption cohorts. Social influence has smaller but meaningful effects, especially among newer online shoppers. Invariance tests indicate that these relationships are broadly stable across the four markets, with differences in the degree to which checkout choice moderates key paths. We discuss implications for CPS-enabled information systems design and platform strategy, emphasizing investments in transparent logistics, sensor-based tracking, and multi-rail payments. Limitations include self-reported behavior and cross-sectional design. We argue that an Asia-specific “trust-first, rails-flexible” CPS architecture, anchored in smart devices and embedded logistics sensors, can nudge consumers toward digital payments without eroding perceived safety.
