① Enroll a fingerprint

Add trusted household users through the approved setup flow so the lock knows who is allowed in.

② Touch the sensor

The 360-degree fingerprint reader is designed to recognize a finger from different angles.

③ Unlock after a match

When the enrolled fingerprint matches an approved user, the door unlocks without needing a phone, code, or key.

what it means

A biometric key, approved by you.

Touch-to-unlock is simple on the outside and controlled on the inside. The lock reads an enrolled fingerprint as a biometric credential, checks whether it belongs to an approved user, then unlocks when there is a match.

How tap-to-unlock works at the door

One NFC lock. Multiple ways to tap.

The value of NFC is flexibility. Different users can rely on different NFC credentials without turning the page into a list of every smart lock feature.

NFC solves more than “unlocking”. It simplifies the moment at the door.

Built for shared front doors.

A front door is rarely used by one person. NFC lets the same lock support different tap credentials for different comfort levels, routines, and access needs.

Primary users

Compatible phones can become daily tap keys for regular entry.

Kids or active users

A watch or card can be easier than remembering a code, where supported.

Older relatives

A card or key fob can feel familiar without adding another app.

Guests and helpers

A physical tap credential can be easier to hand over and explain.

A familiar tap, now for your front door.
