In light of Sri Lankans’ widespread usage of mobile phones and other mobile devices, the objective of the aforementioned research, which was conducted by the author, is to analyse users’ acceptance of Quick Response (QR) code mobile-driven payment systems. Using the UTAUT2 (Unified Theory of Ac- ceptance and Use of Technology 2) model, the current study was developed. This study creates a conceptual model to identify the key elements affecting user intention, perceived satisfaction, and recommendation to utilize QR code payments as a platform for payments when shopping and using services in retail. 484 results from an online survey conducted in Sri Lanka were used in the study model. The study looked at how innovativeness, use stress, and social influence affected how satisfied users felt and whether they would pro- mote QR Code payment methods to others. The study found that ease of use, perceived usefulness, and attitude all had a substantial impact on users’ inten- tions to use QR Code payment methods, which in turn affected users’ percep- tions of their pleasure with the technology and recommendations to use the technology. The study also found a strong moderating impact of social influ- ence and use stress on users’ perceptions of satisfaction and recommendations for QR Code payment methods. It was evident that, in the Sri Lankan context, perceived risk and innovation had a negative effect on the intention to adopt QR code payment methods. Also, the entire study focuses on consumers’ ac- ceptability of using QR Code payment platforms in Sri Lanka, and academics might conduct further research into the topic of Sri Lankan merchants. 232 journal papers were examined for the total literature assessment, and the UTAUT2 theory was identified.
