Classroom Presence System, Development Phases
The four-phase roadmap from a contact-tap RFID prototype to fully contactless, room-scale presence detection.
From Contact-Tap Prototype to Contactless Presence
The hardest part of this project, antennas that reliably detect presence without a tap, is deliberately last. The build is staged so each phase produces something usable and testable on its own.
Phase 1 reflects the current working prototype. This is a hardware rollout roadmap, a different axis from the research cycles in the Research Proposal. See Iterations for how the project's framing itself changed.

Later, If Data Supports It
The Research Proposal explicitly pauses this hardware work until the research cycles show which input is actually worth deepening: "None of it answers a research question until data shows RFID is the right input." Kept here as a condensed record of the plan, not an active workstream.
| Stage | What it was |
|---|---|
| Classroom pilot | Hardening the tap system for a real class period: a deck of RFID-stickered playing cards (one per student), a production backend and admin dashboard, real auth, off SQLite. |
| UHF doorway transition | Swap the tap pad for contactless UHF reads at a single door-table rig, tags mounted on laptops instead of tapped, and the start of a Camera Events contract with the face-scanning system. |
| Full room-scale presence | Front and back door UHF detection, full RFID and camera correlation, the complete presence-state machine (present, tardy, stepped out, left early, opted out, tamper) running live in the trial room. |
