Cryptographic Identity Verification for Every Regulated Delivery.
Cannabis. Pharmacy. Controlled Substance Delivery. VerifiedKnock proves who is at the door — cryptographically, offline, in under 2 seconds — before a single item changes hands.
The Compliance Gap
At the moment a delivery agent arrives at a residential address, there is no cryptographic, tamper-proof mechanism to simultaneously verify the agent's identity, their authorization to deliver the specific regulated item, and the recipient's eligibility — all before the door opens. Every existing method (photo ID scan, QR code, GPS check-in) can be spoofed, shared, or forged.
Hardware-Rooted Identity
FIDO2 biometric key — the private credential never leaves the hardware. Cannot be copied, shared, or transferred.
Offline Capable
Full verification at the door with zero internet connectivity. No dropped connections, no failed deliveries.
Regulatory Audit Log
Immutable, cryptographically signed record for every delivery — formatted for METRC, DEA CSOS, and state ABC authorities.
Two Verticals. One System.
The same PKOC NFC + biometric credential architecture adapts to every regulated delivery use case without additional hardware.
Cannabis Delivery
State Cannabis Regulatory Boards · METRC · BioTrackTHCThe problem: State cannabis boards require tamper-proof identity verification at the point of delivery. Failure to verify results in license revocation, fines, and civil liability for delivering to minors or unverified recipients.
The solution: VerifiedKnock cryptographically binds the driver's FIDO2 biometric credential to the specific order and recipient address. The recipient confirms eligibility via their smartphone's built-in biometric authenticator before the door opens. Every interaction produces a METRC-compatible audit record.
- Driver identity cryptographically proven before door opens
- Recipient age-gated eligibility attestation via smartphone biometric
- METRC and BioTrackTHC compatible audit log
- Works offline — no cell signal required at point of delivery
Pharmaceutical & Schedule II Delivery
DEA CSOS · State Pharmacy Boards · HIPAAThe problem: Schedule II prescription deliveries require verifiable chain-of-custody documentation. Paper signatures are easily forged. App-based photo ID scans can be spoofed. DEA liability for unverified deliveries is significant.
The solution: VerifiedKnock generates a DEA CSOS-compatible electronic delivery record binding the courier's identity, the prescription authorization, the dispensing pharmacy's DEA registration, and the patient's biometric acknowledgment — all in a single cryptographic audit entry.
- Courier identity bound to specific prescription and patient
- DEA CSOS-compatible electronic delivery record
- Patient acknowledgment via FIDO2 platform authenticator
- Eliminates paper signature fraud
Identity Verified.
Before the Door Opens.
The courier taps their VerifiedKnock ATKey.Card to the NFC reader. The on-card fingerprint sensor matches the enrolled biometric — entirely within the hardware secure element. A cryptographically signed delivery record is generated instantly, offline, with no data transmitted to any server.
- On-card biometric — fingerprint never leaves the chip
- DEA CSOS compliant delivery record generated automatically
- Chain of custody logged with cryptographic signature
- Works fully offline — no Wi-Fi or cell signal required
Regulatory Compliance Audit Log
Every VerifiedKnock delivery interaction produces an immutable, cryptographically signed audit record formatted for the applicable regulatory authority.
Cannabis
METRC / BioTrackTHC compatible
Pharmacy

Controlled Substance
DEA Schedule II–V chain-of-custody
Tamper-Proof. Cryptographically Signed. Regulator-Ready.
Every VerifiedKnock delivery interaction produces an immutable audit record — binding the courier's identity, the recipient's biometric acknowledgment, and the delivery authorization into a single signed entry. No paper. No spoofable QR codes. No ambiguity.
Controlled Substance Delivery Compliance — Answered
Everything compliance officers, pharmacy operators, and home health administrators need to know about cryptographic delivery verification.
DEA Compliance
VerifiedKnock addresses DEA Schedule II–V controlled substance delivery requirements by providing a cryptographically signed, timestamped proof of authorized recipient identity at the point of delivery. Compatible with DEA CSOS electronic record requirements.
DSCSA & Chain of Custody
The Drug Supply Chain Security Act (DSCSA) requires serialized traceability from manufacturer to patient. VerifiedKnock closes the last-mile gap: cryptographic proof that the authorized recipient accepted the delivery, not just a paper signature.
Privacy & Security
No biometric data is stored on VerifiedKnock servers. Fingerprint matching occurs on the hardware card itself (match-on-card). The system works fully offline. Simple as a doorbell sticker, secure as a bank card.
