studQ
A QR-powered attendance system for efficient and secure exam participation
task: Design and develop a mobile application that allows professors to manage exam attendance with QR code scanning, eliminating the need for manual ID checks while increasing speed and accuracy of student verification.
tech: Flutter | PocketBase
In academic institutions, verifying the identity of students during exam entry has traditionally relied on manual checking of ID cards and attendance lists. This process is slow, error-prone, and stressful for professors, especially when managing large groups under time constraints.
The studQ app addresses this problem by offering a QR-code-based identification system, allowing professors to verify students’ presence with a quick scan instead of cross-checking physical documents.
How it works
Each student, upon being added to the system, is issued a unique, persistent QR code. This code is sent to their email and remains the same throughout their education.
Before the start of any exam (called an event in the app), professors can:
- Create a new event, set its start time, and assign applied students
- Manually add or import student data via CSV
- View a detailed participant list showing full name, student ID, email, and a checkmark for attendance
Scanning phase
Scanning becomes available 30 minutes before the event and remains active until 30 minutes after it begins. This window ensures structure while enforcing participation policies.
During scanning:
- The professor opens the event and taps the scan icon
- The app activates the camera and awaits QR input
- Upon successful scan:
- If the student is applied to the event, they’re marked as present
- If the student is not applied, a warning is shown and access is denied
This ensures only verified, pre-registered participants enter the exam room, saving time and improving security.
Key features
- Clear event lifecycle management (upcoming, in progress, completed)
- Email dispatch with personal QR upon student registration
- Bulk CSV import
- Fast QR scanning with instant feedback
- Real-time attendance tracking
Vision for the future
The goal is for studQ to be fully integrated into school systems. When students enroll and receive IDs, they are automatically registered in the app.
Potential use cases:
- Attendance for lab work or special lectures
- Controlled access to facilities
- Secure participation tracking across academic activities
With a lightweight backend (PocketBase) and scalable Flutter frontend, studQ is ready for institutional use.
