How does palm vein entry work?

You hold your palm over the sensor, which reads the vein pattern under the skin. It needs no contact and no free hand for a key, and a PIN code works as a backup.

Can it be used outdoors?

Yes. It carries an IP65 rating, which means it is sealed against dust and water jets. That makes it suitable for an exterior door exposed to weather.

No. It is wireless, so it runs on its own power rather than a wired connection to the door frame. Check the battery type and expected life before buying.

Is it a full deadbolt replacement?

It is a keypad lock with a code and palm vein unlock mechanism. Confirm the door prep and backset it fits before ordering, since it replaces the existing lock hardware.

How does it compare with a fingerprint lock?

Palm vein reading works without touching the sensor and is harder to spoof than a fingerprint. Fingerprint locks are usually faster and more widely supported by apps.
