We secure the critical moment at the doorstep by answering three fundamental questions with mathematical certainty.
For sensitive deliveries like opioids, oxygen, or evidence, knowing "someone" received it isn't enough. VerifiedKnock creates a cryptographic link between the sender, the courier, and the verified recipient.
Pharmacy or Agency initiates delivery. Package ID is cryptographically bound to the specific recipient's profile.
Courier scans badge at door. VerifiedKnock confirms identity and authorizes the specific package release.
Recipient confirms via app. Digital signature proves exactly WHO received the item and WHEN.
"We know WHO is at the door."
"We confirm they are AT THE DOOR."
The VerifiedKnock NFC sticker belongs to the homeowner and is registered to their address. Every time it is tapped, the homeowner receives a cryptographic notification through their app — showing who tapped it, when, and with what verified credential. You cannot tap it remotely. Physical presence at that specific sticker is the only way to trigger a verification.
"We know WHO AUTHORIZED them to be there."
Every credential issued by VerifiedKnock is cryptographically bound to the issuing agency's jurisdiction. A Canadian agency's card cannot verify in the United States — and vice versa.
Jurisdiction validation happens on-card during the NFC tap — no internet connection required. Even in a fully offline environment, a cross-border credential is rejected at the hardware level.
VerifiedKnock provides the only access control system designed specifically for the high-stakes requirements of law enforcement and critical infrastructure.
