What Are Fingerprint Door Locks?

Fingerprint door locks fall into the category of biometric locks. As the name suggests, these locks use biological measurements to verify a person's identity. Besides a fingerprint, they can store facial features, for example, and use them to authorize access.

Biometrics replace a traditional key. This means smart locks based on fingerprint or facial recognition provide more convenience because you don't have to carry around a key.

In addition to more convenience, biometric door locks also provide a higher level of security. They require the owners of the property to be present or they won't unlock.

If a lock positively identifies the owner based on his fingerprint, it can then prompt him to enter his code, making it even harder for unauthorized persons to gain entry. This procedure is called multiple-factor authentication and can be enabled on most biometric smart locks.
