This project presents an ESP32-based RFID Attendance System designed to modernize and streamline student registration in a school environment. The system integrates an MFRC522 RFID reader for rapid and accurate student identification, an I2C LCD module for instant visual feedback, and a custom-built Telegram bot that enables seamless remote interaction between teachers and the system. Each student’s unique UID is securely stored within the microcontroller’s internal memory, effectively removing the dependency on external databases and reducing setup complexity.

The project’s core innovation lies in its optimized communication protocol — it eliminates the need for continuous data transmission, instead offering an on-demand absent list feature accessible via a simple Telegram command (/absent_list). This design not only minimizes unnecessary digital traffic but also enhances privacy and data efficiency. Additionally, the system includes personalized LCD greetings for each student and emoji-enriched notifications that trigger only when an absent student arrives, creating a friendly and engaging user experience. Overall, the system provides a cost-effective, reliable, and user-friendly solution for real-time attendance management.
