The Attendify Attendance Flow

From lecture creation to cryptographic validation and instant gradebook sync in 4 transparent steps.

Step 01

Teacher Creates & Configures Session

In under 15 seconds, the instructor chooses course name, start/end time, and optional geofence coordinates with radius.

Session Created: “Algorithms & Complexity” (Radius: 75m)
Step 02

Projector Displays Rotating Dynamic QR

The session page projects a high-contrast QR code with a 15-second countdown timer. Each cycle generates a new cryptographic token hash.

HMAC Token v14 • Expires in 12s • Screenshots invalid after expiry
Step 03

Students Scan Using Browser or PWA

Students open Attendify on any smartphone browser or install it as a lightweight PWA. Camera scans the code in under 2 seconds.

Camera decoded QR • GPS distance: 16m from center • Verified ✅
Step 04

Instant Verification & Background Auto-Sync

Attendance is confirmed immediately. If network connectivity drops inside the lecture hall, the check-in is buffered in IndexedDB and syncs automatically.

Real Feedback from Instructors & Students

Hear how Attendify replaced roll calls and paper sheets across lecture halls.

  • “Attendify completely eliminated attendance proxy fraud in my 200-student lecture hall. The rotating QR code means students can't just screenshot and text it to absent roommates.”

    D
    Dr. Marcus VanceProfessor of Computer Science, State University
  • “Our auditorium has thick concrete walls and virtually zero cellular reception. The offline PWA sync is an absolute lifesaver. Attendance logs reliably every single lecture.”

    E
    Elena RostovaLecturer in Biomedical Engineering
  • “Checking in takes less than two seconds on my phone. No clumsy attendance apps that take 5 minutes to load or paper sign-in sheets being passed around mid-class.”

    J
    Jordan LeeThird-Year CS Student Representative
  • “Deploying Attendify across 14 departments required zero hardware investment. Instructors use their laptops and students use their phones. Seamless integration.”
