RFID-Enabled Access Control with Integrated User Database Logging

This paper focuses on the research, development, and simulation of an RFID-based access control system for applications to enhance security for restricted areas and systems. The system authenticates users by reading RFID tags and verifying data contained within them against a preconfigured database. Access is granted or denied based on these credentials. The system integrates a PIC16 microcontroller, a regulated power supply, relays, and motors for controlling entry and exit points, LED indicators, and an LCD for visual feedback. Upon successful validation, the system triggers a motor to manage the locking mechanism, while failed attempts are met with no mechanical action. To enhance functionality, the system logs each access attempt with details such as time, date, and user credentials for security and administrative analysis.
