The COVID-19 pandemic has transformed the way people interact with technology and conduct transactions. As cashless transactions become increasingly important, digital payment applications have experienced a significant surge in usage worldwide. The objective of this study is to identify the factors that influence user acceptance of fintech applications in Indonesia using UTAUT and TTF. The findings indicate that usability, ease of use, perceived self-control, and perceived trust have a positive and significant impact on users' intention to use fintech applications. However, perceived security does not appear to have a significant influence on users' intention to use fintech applications. Data were collected from active users of digital payment app. Findings indicate that app experiences generate usability, ease of use, perceived self-control, and perceived trust among active users of the app. This research provides a valuable contribution to understanding the factors that affect the acceptance and use of fintech applications in Indonesia. For fintech businesses, this research may assist fintech application developers in enhancing application features and functionality to better suit user needs and preferences. © 2023 Published by the ISTES Organization
