One Plug.
Verified.
Delivered.
Open the app. Plug in ATKey.Pro. Scan the door sticker. Homeowner gets notified instantly. That's it.
Just plug, scan, and deliver — the homeowner gets cryptographically notified before they open the door.
Who is actually at your door?
Every day, residents open their doors to delivery drivers they cannot verify. No platform — DoorDash, UPS, FedEx, or Amazon — cryptographically proves the person at your door is who they claim to be. VerifiedKnock changes that.
Three Steps. Zero Friction.
The ATKey.Pro plugs directly into any iPhone (Lightning) or Android (USB-C). No pairing. No Bluetooth. No app to download.
Plug In
Driver plugs the ATKey.Pro into their phone. Their fingerprint is already saved on the key — it only works for them, no one else.
Touch to Verify
Driver touches the fingerprint sensor on the ATKey.Pro. Biometric match happens on the hardware — fingerprint never leaves the device.
Tap the Sticker
Phone taps the VerifiedKnock sticker on the door. The resident gets an instant alert on their phone showing who is at the door — name, delivery company, and time. The driver's screen shows a green checkmark. Both sides know it's real.
