Encrypted RFID asset tracking across 11 vaulted facilities: audit trail to the second
A high-security tracking solution for instruments, documents and high-value assets, with an immutable audit log that survives both internal and regulator scrutiny.

The challenge
- Manual register-based tracking of high-value documents and instruments.
- Audit cycles required reconstruction of the asset chain-of-custody from paper.
- Regulator pressure to demonstrate continuous, tamper-evident tracking.
What we built
- HF RFID with encrypted ICs for sensitive documents and instruments.
- UHF RFID for bulk vault movement.
- Tamper-evident audit log with cryptographic chaining.
- Role-based access with named accountability per event.
- Read-only dashboards for internal audit + regulator.
Why this is not regular RFID
High-security asset tracking has constraints that warehouse RFID does not: encrypted ICs, tamper-evident logs, role-based access at the event level, and audit logs that have to convince a regulator — not just an internal auditor.
The audit win
What used to take days of paper-based reconstruction is now a single dashboard query. The internal audit cycle compressed from weeks to days, and the regulator briefings became conversations instead of explanations.
