QR Code Conference Check-in System 🎫

This project is a simple Flask-based web application designed to generate unique QR codes for conference attendees. Each attendee receives a personalized QR code upon registration, which can later be scanned at the event entrance to mark their attendance.

🛠 Features

• ✅ Attendee registration with name and email
• ✅ Automatic generation of a unique QR code for each attendee
• ✅ Generation of personalized ID cards with QR codes
• ✅ Simple interface for scanning attendee QR codes and marking attendance
• ✅ Admin view to see the list of all registered attendees
• ✅ Attendance status management (checked-in flag)

📦 Technologies Used

• Flask - Web framework
• SQLite - Lightweight database
• SQLAlchemy - ORM for database interaction
• Pillow (PIL) - For ID card image generation
• qrcode - For QR code generation
• OpenCV & pyzbar - For QR code scanning

🚀 How It Works

Register Attendees: Users fill in their name and email on the registration page. A unique QR code and an ID card image are generated for them.

• Check-in Process: At the event, attendees present their QR code at the check-in station. The system scans the QR code and marks them as 'checked-in' if valid.

• Admin View: Admins can view a list of all attendees along with their check-in status.

⚡ Requirements

• Python 3.x
• Flask
• Flask SQLAlchemy
• Pillow
• qrcode
• OpenCV
• pyzbar ##📌 Notes
• Generated QR codes and ID cards are stored in the /static/qrcodes/ and /static/idcards/ folders respectively.
• Attendance data is stored in an SQLite database file attendees.db.
• You can modify the HTML templates to fit your conference branding.
• For QR scanning, the current implementation uses image upload. It can be extended to use a live camera feed if needed.

##📷 Screenshots (You can add screenshots of the registration form, ID card example, and the check-in interface here.)

💡 Future Improvements

• Live camera-based QR scanning
• Admin authentication
• Email notifications with QR codes
• CSV export of attendee data
