End the Fear of the
Unexpected Knock.
Empower seniors to verify visitors without opening the door. Stop scams, fraud, and confusion before they start.
The "Grandparent Scam" Stops Here.
Imposters prey on trust. VerifiedKnock replaces trust with secure proof, giving seniors a simple "Green Check" or "Red X" for every visitor.
Zero Confusion
No complex apps. If the phone doesn't vibrate with a verified photo, the door stays closed. Simple as that.
Family Alerts
Optional notifications can be sent to adult children or caregivers whenever a verification occurs, adding a second layer of oversight.
Utility & Service Safety
Verifies legitimate utility workers and contractors, preventing criminals from using "meter checks" as a pretext for entry.
The Green Light of Trust
We turn the entire room into a verification interface. When a verified visitor arrives, your smart home lights turn a calming green. No apps to open, no screens to read.
Green Means Safe
If the room glows green, the person outside has been securely verified by the agency. Simple, intuitive, and fail-safe.
Zero-Interaction
Seniors don't need to find their phone or glasses. The environment itself communicates safety instantly.
Open Ecosystem
Designed to integrate with any smart home platform. We provide the secure signal; your existing hub controls the lights.

No phone. No app.
Just tap and know.
For seniors who don't use smartphones, VerifiedAmbient™ includes a dedicated wall-mounted NFC reader that installs beside the door like a light switch. When a verified officer or worker taps their credential card to the reader, the device signals instantly — no screen to read, no app to open, no Wi-Fi required.
A dedicated reader. No sticker, no phone, no compromise. The VerifiedAmbient™ reader communicates directly with the VerifiedKnock system and triggers the ambient light signal in the home — turning the room green for verified visitors, red for unverified ones.
No Smartphone Required
Designed specifically for seniors who don't own or use a smartphone. The hardware does everything.
Works Offline
The NFC credential verification is cryptographic and works without an internet connection — fully reliable even during outages.
Same Security as the App
The dedicated reader uses the identical FIDO2 cryptographic verification as the mobile app — no compromise on security for seniors.
Officer taps FIDO2 card to reader
Reader verifies credential cryptographically
Room light turns green — safe to interact
Choose the right setup for your household
Both options use the same FIDO2 cryptographic standard. The difference is how the resident receives the verification signal.
Passive NFC Sticker
A cryptographically secure NTAG424 DNA sticker placed at your door. Set it up once via the VerifiedKnock app — no power, no maintenance, no hardware to install.
VerifiedAmbient™ Dedicated Reader
A wall-mounted NFC reader that installs beside the door. No smartphone, no app, no Wi-Fi required. The officer taps their FIDO2 card — the room signals green instantly.
