This research aims to develop an effective security system in managing access to sensitive financial records. The method used is Research and Development (R&D), which includes steps to identify problems, collect data through observation, unstructured interviews, and documentation, system design, system creation, and prototype testing. The designed system utilizes key components, including an
... [Show full abstract] Arduino Uno R3 as a microcontroller, an FPM10A fingerprint sensor for user authentication, a 4x4 keypad as an authentication alternative, a relay module to control the solenoid lock mechanism, and a blue LED to indicate the system status. The result of this research is a prototype of a system capable of securing financial archive doors with an adequate level of accuracy and speed in the fingerprint authentication process. Through a series of tests, the system has been proven to improve the security and efficiency of access to financial archives, as well as offer innovative solutions for the management of a more modern security system at Dinas Pariwisata. It is hoped that this research can contribute to the development of security technology and improve the quality of archive management in government agencies.
