However, users’ intention to adopt fintech payment is strongly influenced by their perceptions of usefulness, ease of use, and security. This study aims to analyze the effects of perceived usefulness, perceived ease of use, and perceived security on the intention to use fintech payment among Generation Z in Sidoarjo Regency. This research employs a quantitative approach using purposive sampling, involving 200 respondents who have used fintech payment services for at least three months. Data were collected through online questionnaires and analyzed using Structural Equation Modeling based on Partial Least Squares (SEM-PLS) with SmartPLS 4.0 software. The results indicate that perceived usefulness, perceived ease of use, and perceived security have poitive and significant effects on the intention to use fintech payment. Among these variables, perceived usefulness has the most dominant influence on usage intention.
