Choosing the Right Digital Lock: Fingerprint, Face Recognition, or PIN?

PROLOCK's digital locks support more than one way in — face recognition, fingerprint, PIN code, smart card, and a mobile app. Picking the right combination comes down to your lifestyle and the kind of space the lock will guard.

Fingerprint: fast and personal

For homes with a fixed set of residents (not heavy guest traffic), fingerprint is the fastest, most natural way in — no code to remember, no card to carry. A model like PROLOCK PR-410C is built exactly for this scenario: quick fingerprint entry backed by card and mechanical key as fallbacks.

Face recognition: hands-free and modern

When your hands are full — groceries, a child in your arms, or you just want a fully contactless experience — 3D face recognition is the best option. PROLOCK PR-700K offers this alongside fingerprint, card, and app control, so you can switch methods depending on the moment.

PIN and card: built for guests and staff

In settings like an office, hotel, or rental unit where users change constantly, a temporary PIN code or a smart card — with no need to enroll everyone's biometrics — makes access management far simpler.

The practical answer: filter by what you need

Still torn between methods? On the PROLOCK products page, you can filter by the exact unlock method you want (fingerprint, face recognition, PIN, card, or app) and see only the models that match.
