Software Quiz App

I quickly developed a quiz application as a fun activity for students visiting our booth during the university club promotion days.

Features

• QR code generation on team members’ phones
• Quick access to the quiz via QR code
• 30-second time limit
• 3 different questions in the software field
• Prize-winning chance for those who answer all questions correctly

How It Works

1. Team members generate a unique QR code on their phones
2. Students at the booth scan this QR code with their phones
3. Contestants try to answer questions from the server within 30 seconds
4. Answers are securely verified on the server and results are sent to the user
5. Contestants who answer all questions correctly win a prize
