01What problem does it solve?

Traditional manual attendance taking is time-consuming, prone to proxy attendance, and lacks real-time updates for instructors and academic administration.

02Constraints & Tradeoffs

Must be contactless, fast (sub-second scan processing), secure against proxy check-ins (e.g. time-limited QR codes), and support reliable data logging with relational integrity.
