Why Choose This Project?

With increasing security concerns during travel—especially at public places like airports, railway stations, and tourist spots—there is a growing demand for smart, secure, and tech-enabled locker systems. This project provides a modern, IoT-based solution using RFID and OTP authentication to allow safe and user-friendly storage during travel.

This system is ideal for engineering students who want to combine hardware (IoT/embedded systems) with software (web or mobile interface, databases).

What You’ll Get

• Complete Embedded Code (e.g., Arduino with RFID + Keypad)

• Secure RFID-Based Locker Access

• OTP Verification via SMS or Email

• Admin Panel for Locker Management

• Web Dashboard to Monitor Locker Usage

• Mobile-Friendly Interface (Optional)

• Integration with GSM Module or Wi-Fi for communication

• Full Documentation & Circuit Diagrams

Working Flow 

1. User scans RFID card at locker terminal

2. System checks card validity (via microcontroller or backend)

3. If valid → generates OTP and sends to user (via SMS/email)

4. User enters OTP via keypad or web interface

5. Locker opens on successful OTP match

6. System logs the transaction (locker number, user ID, time)

7. Admin can view usage logs and reset lockers
