<p>Cashless payment is known for increasing consumers’ impulsive buying, yet the impact of different types of cashless payment is distinct. Although QR code payment is increasingly popular, research on its impact in increasing impulsive buying is still limited. Drawing from the Stimulus-Organism-Response framework, this research contributes to the literature by integrating utilitarian stimulus (i.e. perceived ease of use) and hedonic stimulus (i.e., pain of paying) as well as individual factor (i.e., hedonic shopping motivation) to examine the effects of QR code payment on Impulse Buying. An online survey was conducted and collected 416 valid responses from consumers who have experience in using QR code payment. The data were analysed using Hayes’ Macro Process revealing that both the pain of paying and perceived ease of use have substantial influence on impulsive buying as mediated by satisfaction. Moreover, hedonic shopping motivation significantly moderates the indirect effects of pain of paying and perceived ease of use on impulse buying as mediated by satisfaction. This paper delves into the implications and offers recommendations for future research.</p>
