Mobile App with QR Code Validation

Job ID: 39095683

Budget: ₹1,500 – ₹12,500 INR

I'm looking for a mobile-friendly application that leverages QR code technology for scanning. The app's primary function is to validate entry via mobile devices. Each QR code should be designed for one-time use only. The app should also maintain a database of phone numbers and names in two separate tables.

Key Features:
- User authentication for both administrators and participants, ensuring a secure environment.
- A feature that generates attendance records.
- In-app notifications to confirm scans.
- An analytics dashboard that provides usage statistics.

Preferred Technologies:
- Frontend: React Native.
- Backend: Node.js with Express.js.
- Database: MongoDB.
- QR Code: 'qrcode' library.
- Notifications: Firebase Cloud Messaging.
- Analytics: Google Analytics for Firebase.

I'm open to other effective solutions if you have them. If you're experienced with these tools and have a solid understanding of mobile app development, particularly with React Native and Node.js, I would love to hear from you.
