It is carried out on the population of Serang City, which has a total of 730,530 people. A sample was drawn using the Slovin formula with an MoR of 10%, namely 100 respondents. This study also aims to prove the influence of applying QRIS on buying interest. The determination of respondents is carried out as one of the instruments, namely using the purposive sampling technique.
