Trusted by Forward-Thinking Agencies & Utilities
"Knowing who is at the door before opening it changes everything for vulnerable residents."
Safety Through
Certainty.
Uncertainty breeds fear. Fear leads to escalation. VerifiedKnock removes the uncertainty from the moment of arrival.
Eliminate "The Unknown"
Residents no longer have to guess if the person at the door is a legitimate officer or an imposter. The verification happens before any interaction — so residents can make an informed decision.
Protect Your Officers
When a resident feels safe, they are less defensive. VerifiedKnock creates a calmer, safer environment for officers to conduct their duties.
Your door is blind. Until now.
A standard doorbell shows you someone is there. VerifiedKnock proves they belong there — cryptographically, before the door opens.
Simple. Secure. Instant.
No complex training required. If you can use a credit card, you can use VerifiedKnock.
Biometric Unlock
Officer presses their thumb on the ATKey.Card sensor. Match-on-card biometrics unlock credentials — fingerprint data never leaves the card.
Tap the Door
Officer taps their ATKey.Card to the NFC sticker on the door frame. A cryptographic challenge-response proves identity and physical presence — offline, instantly.
Resident Notified
The resident's phone receives a push notification: department name, dispatch reference number, and verified timestamp. No officer PII. No guessing. Open with confidence.
Two ways to receive. One standard of trust.
VerifiedKnock works for every household — whether you prefer a smartphone app or no technology at all.
Passive NFC Sticker
A cryptographically secure NTAG424 DNA sticker placed at your door. Tech-savvy residents set it up once via the VerifiedKnock app — no hardware, no power, no maintenance.
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.
Recent Impersonation Incidents
Real-time tracking of verification failures and impersonation attempts.
Fake Officer Ties Up Homeowner in Invasion
A suspect impersonating a police officer broke into a Tacony home, handcuffed the resident, and robbed the property. Police warn residents to verify ID.
Imposter Nurse Treated 4,000 Patients
A woman using stolen credentials worked as a nurse for months, treating thousands of patients before being caught. Highlights the failure of visual ID checks.
Scammers Posing as Utility Workers for Entry
Officials warn of criminals posing as water/power employees using high-pressure tactics to gain entry to homes. Residents urged to call utility companies to verify.
Fake Delivery Alerts Used to Prime Victims for Door Scams
Scammers send fake Amazon, FedEx, and UPS delivery notifications via text or email, then send an accomplice to knock on the door while the victim's guard is down. The digital notification is the setup — the physical knock is the attack. VerifiedKnock eliminates this by requiring cryptographic proof of identity at the door, regardless of any prior notification.
Fake Water Inspectors Target Elderly
Thieves claiming to test water quality are targeting senior citizens to gain access to valuables. Police remind citizens that real workers have scheduled appointments.
Don't become a statistic. Verify identity before you interact.
Calculate Your Agency's ROI

The High Cost of
"Is This Real?"
Every time a resident calls 911 to verify an officer's identity, two resources are tied up: the dispatcher handling the call and the officer waiting at the door.
Recover Lost Time
Eliminate the 5-10 minute "verification gap" on routine warrant services and welfare checks.
Unclog Dispatch Lines
Reduce non-emergency call volume so dispatchers can focus on active incidents.
Average number of times residents call dispatch to verify an officer.
Time spent by dispatch and officer resolving the verification.
Fully loaded hourly cost (salary + benefits + vehicle + overhead).
Methodology: Fully-loaded officer cost of $95/hr reflects 2025–2026 California public safety compensation data, including base salary, benefits, pension contributions, vehicle operation, and departmental overhead. Sources: California State Controller's Office public pay data; RAND Corporation The Cost of Police Misconduct (2023); International City/County Management Association (ICMA) public safety cost benchmarks. Verification call resolution time of 8 min. is based on typical dispatch-to-officer callback cycles documented in 911 CAD system studies. Actual savings will vary by agency size, call volume, and local compensation rates.
"Does it transmit my fingerprint somewhere?"
No. The fingerprint never leaves the card. Here's exactly what happens when an officer taps.
Finger Touches Card
The officer's fingerprint is read by the sensor on the card itself. The biometric template is stored in the card's tamper-proof secure chip — never on a server.
Card Verifies Internally
The card compares the fingerprint to its stored template entirely inside the chip. No fingerprint data is ever transmitted — not to the phone, not to our servers, not anywhere.
Only a Signature Is Sent
A cryptographic signature — mathematically impossible to reverse into a fingerprint — is transmitted. Our system verifies the signature. That's it.
