The results of the study showed that four factors of consumption behavior, namely cultural factors, social factors, personal factors, and psychological factors, have a positive and significant impact on students' decisions to use QRIS. Evaluation of the F-square value F2 shows that psychological factors (internal motivation, perceived ease, security, and trust) are the most dominant predictors with the largest effect value of 0.434 in influencing the decision to adopt this digital payment system technology.
