Verified Access for
Critical Infrastructure.
Utility impersonation scams cost Americans millions each year. VerifiedKnock gives your field technicians a cryptographic credential that customers can verify instantly — before any interaction, no phone call required.
VerifiedKnock confirms the identity of the visitor. The decision to interact remains solely with the resident.
The Utility Impersonation Problem
Scammers posing as utility workers are one of the most common home-access fraud schemes. A uniform and a clipboard are all it takes to gain entry.
Cost of a fake utility vest
A uniform, hard hat, and clipboard are freely available. Physical appearance proves nothing about identity or authorization.
Rising utility scam reports
Utility impersonation scams are consistently among the top consumer fraud categories reported to the FTC each year.
Existing cryptographic solutions
No field-deployable system currently allows customers to cryptographically verify a utility worker's identity before any interaction.
How It Works for Field Technicians
The same ATKey.Card + NFC sticker system used by law enforcement — adapted for utility and field service operations.
Technician Authenticates
The field technician presses their enrolled fingerprint on their ATKey.Card. The biometric match-on-card confirms the technician is the authorized credential holder — no network connection required.
Card Taps the Sticker
The technician taps their card to the NTAG424 DNA NFC sticker on the door frame or meter box. The sticker generates a unique cryptographic challenge — every tap produces a different response that cannot be replayed or faked.
Customer Receives Notification
The customer's phone instantly receives a push notification showing the company name, dispatch reference, and verified timestamp. No technician name or personal information — just the facts needed to make an informed decision.
What the Customer Sees
The notification is designed to be understood instantly. The company name, dispatch reference, and timestamp are the only information shown. No technician identity is exposed.

Why Utility Companies Choose VerifiedKnock
Protect your customers, protect your workers, and reduce liability from impersonation incidents.
Stop Imposter Scams
Give customers a cryptographic way to verify legitimate technicians before any interaction. A uniform and clipboard can be faked. An FIDO2 hardware credential cannot.
Proof of Presence
Every NFC tap creates a cryptographically signed, timestamped visit record. Prove that a technician was physically at the meter or service point at a specific time — unforgeable and location-bound.
Customer Trust
Proactive "Verified Technician" notifications build confidence with customers before they ever see the worker at their door. Reduce customer complaints and improve first-visit access rates.
No Worker Tracking. No Surveillance.
VerifiedKnock does not track technician location in real time. The system proves that the right person was at the right address — it does not monitor their route, schedule, or movements.
Biometrics stay on the card. No fingerprint data is transmitted or stored by VerifiedKnock.
Serving Customers
Without Smartphones.
Many utility customers — especially seniors — don’t own smartphones. The VerifiedAmbient™ Dedicated Reader ensures every household can verify your technician, regardless of technology access.
The wall-mounted NFC reader installs beside the door. When your technician taps their FIDO2 credential, the home signals instantly — green for verified, red for unverified. No app. No Wi-Fi. No screen to read.
Senior Safety FeaturesWall-Mounted NFC Reader
Installs beside the door. No drilling, no wiring. Powered by USB-C or battery.
Universal Accessibility
Designed for seniors and low-tech households. No smartphone, no app, no barrier to protection.
Same FIDO2 Security
Identical cryptographic verification as the mobile app — no compromise on security for any customer.
