The Technical Principle and Functional Advantage of Smart Fingerprint Lock

Smart door locks are becoming increasingly popular, but despite its fame, fingerprint locks are actually relatively rare. They are the perfect combination of computer information technology, electronic technology, mechanical technology, and modern hardware technology. In this article, we will explore the technical principles and functions of fingerprint locks.

1. Technical Principle Of Smart Fingerprint Lock

Fingerprints are the unique ridges and valleys on the skin of our fingertips. Although it is only a small part of the human skin, it contains a lot of information. Fingerprint patterns, breakpoints, and intersections are known as "features" in information processing. Medical research has shown that these features are unique to each finger, making them a reliable way to identify a person. Smart fingerprint locks produced by smart door lock supplier utilize this principle by comparing the fingerprint features of an individual with pre-saved ones to verify their identity. This technology has become the most important evidence for identifying individuals in public security, criminal investigation, and judicial fields.

2. Functions of Smart Fingerprint Lock

(1) Multiple People Access: A fingerprint lock should allow multiple people to access it, especially in families or offices. The product quality should be stable, and the performance should be reliable.

(2) Authority-Based Access: Access should be granted according to the authority. For example, a householder should have higher access privileges than a nanny or a cleaner.

(3) Easy Fingerprint Management: It should be easy to add or delete fingerprints. For instance, when a nanny leaves her job, it should be straightforward to remove her fingerprint.

(4) Query Record Function: It is best to have a record of who accessed the door and when. This function allows users to view the door record at any time, and can sometimes become a key piece of evidence. In general, fingerprint locks with this feature should be equipped with a display screen or an app.

(5) Password Function: The lock should have a password function (since fingerprint technology is still electronic and may be damaged, the host can use the password to open the door in some temporary circumstances). Usually, there are 4 keys and 12 keys. However, products that heavily rely on password function should be avoided since passwords are not as secure as fingerprints. Passwords should be less used to open the door in daily life.

With this introduction, you should have a better understanding of the technical principles and functions of the smart fingerprint door lock. These locks are generally composed of an electronic identification and control system and a mechanical linkage system. The uniqueness and non-replicability of fingerprints make fingerprint locks the most secure type of lock currently available. Click here for more information about high-quality Tenon smart lock.
