Problem
Attendance monitoring remains vulnerable to proxy registration, shared credentials, static QR screenshots, lost cards, and privacy concerns around biometrics.
Proposal
A hybrid system uses mobile-generated, cryptographically signed QR codes with building gates, classroom QR checks, API validation, and administrative reporting.
Security Model
Codes are time-bound and tied to a device-specific key, with a ten-second epoch used in the QR payload model described by the article.
Expected Outcome
The article expects improved efficiency, reduced administrative workload, better traceability, and fewer opportunities for attendance manipulation.

Notes from the article: * assumes a sophisticated deepfake attack is not used; ** prevented by the ten-second validity and physical presence requirement at the speed gate; *** prevented by device-specific secure key storage.

Conclusion
Educational fictional simulation
Secure Campus - Dynamic QR Attendance Challenge
Design a smart access and attendance system. Stop fraud attempts, protect student data, and keep the campus running under pressure.
Score values are game mechanics for the educational scenario. They are not measurements reported by the article.
Interactive Campus
Mission: configure the system and run the first validation.
Fictional campus map based on the article's entrance, classroom, and exit validation points.
Security Control Panel
Live Event
Mobile Application
Fraud percentages for Static QR, RFID, Biometrics, and Dynamic QR follow Table 3. Bar ratings and Paper Attendance ratings are educational interpretations for the game.
Privacy Risk
Medium
Correct decisions follow data minimisation, purpose limitation, transparency and consent, data security, retention limitation, and the right to be forgotten.
Fictional operational dashboard. Values, names, devices, timestamps, and logs are simulated for the game.

Research Basis
This game is an educational representation inspired by the article's conceptual model for automating access and attendance in educational institutions. Characters, event cards, student names, devices, logs, dashboard values, and scenarios are fictional. The game is not a production-ready security system.
