The Dynamic Attendance QR Display System introduces a cutting-edge solution for precise, real-time attendance tracking at specific locations and times. Unlike traditional static QR stickers, this system leverages a Dynamic QR Code Display Machine that refreshes its QR code at regular intervals — enhancing security, reliability, and versatility across diverse use cases.
⚙️ How It Works
🔄 Dynamic QR Code Refresh
- Display continuously generates unique QR codes at programmed intervals
- Each code is valid only for a limited time window — preventing replay attacks
- Configurable refresh rate (e.g., every 30s, 60s, 5min) per use case
📍 Time & Location Verification
- User's mobile app scans QR + captures GPS location + timestamp
- Backend server validates: QR authenticity ✅ | Time window ✅ | Location range ✅
- Attendance marked only if all 3 checks pass — eliminating proxy/fraud
🔧 Device Configuration
- Configure via text commands or Android app
- Set parameters: unique device ID, location details, auth credentials, initial timestamp, refresh interval
- Plug-and-play USB deployment — no battery or complex setup required
✨ Key Features
- 🔐 Dynamic Code Generation: Eliminates risks of static QR duplication or misuse
- ⏱️ Real-Time Attendance: Captures exact time + location with millisecond accuracy
- ⚙️ Configurable Refresh Intervals: Tailor performance to security vs. battery needs
- 🔌 USB Powered: Lightweight, portable, zero maintenance — deploy anywhere
- ☁️ Cloud Sync Ready: Integrate with HRMS, logistics platforms, or custom dashboards
