Project Description:

The RFID-Based Attendance Tracker is a smart system designed to automate attendance recording using Radio Frequency Identification (RFID) technology. Each student or employee carries a unique RFID card. When scanned at an RFID reader, their presence is automatically logged into the system with a timestamp.

This project is highly applicable in schools, colleges, offices, or events where monitoring attendance efficiently and accurately is crucial.

Technologies Used:

• Backend: PHP / Java / Node.js

• Frontend: HTML, CSS, Bootstrap, JavaScript

• Database: MySQL / MongoDB / Firebase

• Hardware:

  • RFID Reader (e.g., RC522)

  • RFID Tags or Cards

  • Microcontroller (Arduino / ESP32 / Raspberry Pi)

• Connectivity: USB/Serial or Wi-Fi (for real-time sync)

Key Features:

1. Contactless RFID-Based Check-In:

   • Each user scans their RFID card near the reader.

   • System identifies and logs their attendance automatically.

2. Time & Date Stamping:

   • Every scan includes real-time date and time logging.

3. Real-Time Web Dashboard:

   • Admins and faculty can view attendance records.

   • Displays total students present/absent.

4. Student/Employee Profile Management:

   • Store and manage personal details tied to each RFID card.

5. Manual Entry & Correction:

   • Faculty/Admins can manually update attendance if needed.

6. Report Generation:

   • Downloadable attendance reports in CSV/PDF formats.

   • Filter by date range, user ID, or department/class.

7. Notifications (Optional):

   • Email/SMS alerts to parents/employees for late or absent days.

System Workflow:

1. Registration:

   • Users are registered and assigned a unique RFID tag/card.

2. Attendance Recording:

   • RFID reader reads the card.

   • Microcontroller sends UID to backend via serial/Wi-Fi.

3. Data Processing:

   • Backend validates UID, timestamps it, and logs to the database.

4. Dashboard Update:

   • Web interface updates attendance sheet in real-time.

5. Report & Analytics:

   • Generate weekly/monthly attendance stats.
