How It Works
Courier Credential Card
Every courier carries a FIDO2 hardware card with on-card biometric match tied to their verified identity and authorization level.
NFC at Handoff Point
A tamper-evident NFC marker at each handoff point generates cryptographic proof of courier presence.
Handoff Record Created
A tamper-proof, hardware-signed handoff record is automatically created at each transfer point.
Chain of Custody Maintained
Every link in the chain is cryptographically connected — providing an unbroken audit trail from origin to destination.
Regulatory Compliance

Proof of custody that
satisfies every regulator.

DEA, FDA, and state pharmacy boards require documented chain of custody for controlled substances. VerifiedKnock's hardware-signed records provide the highest standard of custody evidence — automatically, at every handoff.
