A real-time Product Tracking System using RFID technology and ESP32, designed for automated data collection, secure handling, and RESTful API integration. This project ensures reliable tracking of goods with LED-based status indicators and focuses on scalability, efficiency, and data integrity.
- 📡 RFID-based Product Identification
- 🌐 ESP32 for Wireless Communication
- 🔄 REST API Integration for real-time data syncing
- 🔒 Secure Data Handling using HTTP authentication
- 💡 LED Indicators to show status (Success, Error, Processing)
- ⚙️ Modular Design for easy scalability and updates
| Component | Technology |
|---|---|
| Microcontroller | ESP32 |
| Identification | RFID Reader + Tags |
| Communication | HTTP/REST API |
| Backend API | Node.js / Express / Flask (customizable) |
| Database | SQL |
| Indicator Feedback | LED lights (Red, Green, Yellow) |
- RFID tag is scanned via the RFID module.
- ESP32 reads the tag and sends data to the backend using a REST API.
- The backend validates and stores the data securely.
- Based on the response:
- ✅ Green LED = Valid Product
- ❌ Red LED = Invalid Tag
- ⏳ Yellow LED = Processing/Waiting
