The study aims to examine the influence of QRIS ease of use and lifestyle on the consumptive behavior on Generation Z in East Java, as well as to investigate the role of self-control as a moderating variable. This research employed a quantitative approach with a casual associative method. Data were collected through an online questionnaire distributed to Generation Z individuals residing in East Java who use QRIS. The sample consisted of 430 respondents. Data were analyzed using Structural Equation Modeling-Partial Least Squares (PLS-SEM) with assistance of SmartPLS 4 software. The result indicate that QRIS ease of use has a negative effect on consumptive behavior, while lifestyle and self-control have positive effects on consumptive behavior. Futhermore, self-control was found to moderate the relationship between lifestyle and consumptive behavior among Generation Z in East Java. The R-square value of 0.620 indicates that the variables included in this study explain 62% of the variance in consumptive behavior, while the remaining 38% is influenced by other factors outside the scope of this study.
