How I Built an Open-Source Attendance System That Eliminates Manual Tracking Forever

The Problem That Started It All

Picture this: You're managing a team of 50 employees, or running a school with hundreds of students. Every morning, you're dealing with:

📝 Manual sign-in sheets that get lost or damaged
⏰ Time-consuming roll calls that eat up valuable minutes
📊 Spreadsheets that require constant manual updates
🚫 No way to verify if someone actually showed up on time
📍 No location tracking to prevent buddy punching
💰 Expensive proprietary software with monthly subscriptions

Sound familiar? I've been there too. That's why I decided to build something better — a complete, open-source attendance management system that's free, powerful, and actually works.

Introducing: Attendance with QR Code

I'm excited to share Attendance with QR Code — a comprehensive solution that combines a WordPress plugin with a Flutter mobile app to create the most efficient attendance tracking system you've ever used.
