Case Study
RFID-based TLD badge control for radiation safety teams
144 slots, slot-level validation, SMS alerts
A radiation safety operation needed to cut manual errors out of TLD badge handling. The TLD Rack Automation System used RFID, slot-level validation, and SMS alerts to keep badge storage, return tracking, and audit trails reliable.
The challenge
What the team was up against
Manual TLD badge management creates real audit and compliance risk: badges land in the wrong slot, missing badges go unnoticed for too long, logbook entries drift from reality, and large badge volumes are hard to manage by hand.
They needed:
- Reduced manual badge-tracking error
- Faster identification of non-returned badges
- Slot-level traceability
- Better audit readiness
- Scalable architecture as headcount grows
The solution
What we built
RFID/NFC readers at every slot identify each badge as it's placed or removed. ESP32 PoE controllers feed a central Raspberry Pi server that handles validation. Slot-level LEDs and buzzers give immediate operator feedback, and an LTE Cat-1 modem pushes SMS alerts to the safety officer when something is off.
What changed
Outcomes
Fewer manual tracking errors
Faster notice when a badge is missing
Slot-level traceability for audits
Scalable rack architecture
