QR Code Attendance System
Take and mark attendance using QR codes with offline sync capabilities for reliable tracking.
The QR Code Attendance System allows teachers to generate QR codes for lessons and students to mark their attendance by scanning the code. The system works offline and automatically synchronizes when internet connection is restored.
OFFLINE CAPABILITY - No need for Wi-Fi
This system works completely offline! Teachers can generate QR codes and students can scan them even without internet connection. All attendance data is stored locally and automatically synchronizes when internet connection is restored. This makes it perfect for classrooms with unreliable internet or remote learning situations.
- Why this matters: Faster attendance taking, reduced manual work, automatic sync even without internet, and accurate student tracking.
- Who uses it: Teachers (to generate QR codes) and Students (to scan and mark attendance).
- When to use it: During live lessons, when you need quick attendance marking, or when internet connectivity is unreliable.
