Fingerprint locks are smart locks that use fingerprints as a means of identification. They represent the culmination of computer information technology, electronics, mechanical technology, and modern hardware craftsmanship. They generally consist of two components: electronic identification and control, and a mechanical linkage system. The uniqueness and irreproducibility of live fingerprints make fingerprint locks the most secure of all locks. In addition to fingerprint recognition, fingerprint locks should also be equipped with an emergency mechanical key.
Due to the widespread adoption of smart homes, fingerprint locks have become ubiquitous in countless households. Their functionality has also become increasingly comprehensive, evolving from fingerprint and password unlocking to NFC sensing and mobile phone unlocking.
Introduction: Fingerprints are the uneven, uneven lines on the front of the fingertip. Although a fingerprint is only a small part of human skin, it contains a wealth of information. These lines vary in pattern, breakpoints, and intersections. In information processing, these lines are called "features." Medically proven, these features are unique and permanent for each finger. Therefore, we can match a person to their fingerprint. By comparing their fingerprint features with pre-stored fingerprint features, their true identity can be verified. Therefore, these characteristics of fingerprints have become the most important evidence for identification and are widely used in public security, criminal investigation, and judicial fields. Fingerprint authentication is convenient, fast, and accurate.

Fingerprint, password, and emergency key functions are now also available, and now card unlocking is also being added, making fingerprint locks more trustworthy and attractive to consumers. Many manufacturers integrate dozens of functions into their products, including doorbells, voice prompts, internet connectivity, and phone alarms. At first glance, the sheer number of features might seem like a way to save unnecessary costs, and users might be tempted. However, I personally believe this is irresponsible design by the manufacturer. The primary function of a fingerprint lock is security and convenience. In addition to unlocking the door, fingerprint locks generally offer the ability to add, delete, and clear fingerprints. High-performance fingerprint locks also feature human-computer interaction systems such as LCD touchscreens, offering a high level of intelligence and relatively easy operation. They also provide user guidance, access to usage history, built-in parameters, and configuration settings. Fingerprint management functions include adding, deleting, and clearing fingerprints, as well as setting system parameters. Standard users only have the door unlocking function.
Fingerprint locks can typically be equipped with other unlocking methods, such as passwords and cards.
Core components of a fingerprint lock: motherboard, clutch (for semi-automatic locks), fingerprint sensor, cryptographic technology, microprocessor (CPU), intelligent emergency key, and power supply (battery charger, transformer, etc.).
