How I Designed an Anti-Proxy Attendance System Using Dynamic QR Authentication

Designing an anti-proxy attendance system using dynamic QR authentication prevents misuse by generating temporary authentication tokens with a limited lifespan. This approach reduces the opportunity for someone to reuse an older QR code and keeps the attendance workflow under server control. Balancing security with usability is crucial, and finding the right balance requires considering actual classroom conditions. This system is part of a larger project that involves multiple smaller decisions working together to achieve security. Future posts will explore the backend architecture, data modeling, authentication flow, and scaling the platform.
