What is a lock used for?

1. Lock Types
Locks, as everyday security tools, have diversified in form with technological advancements and are primarily categorized into the following categories:
Mechanical Locks:
Mechanical locks are the oldest type of lock. Their core principle is to achieve locking and unlocking through a physical mechanical structure. These locks rely on a physical key or combination, operating through the precise coordination of mechanical components. Typical products include padlocks, latch locks, and rotary locks. Mechanical locks are simple in structure and low in cost, making them suitable for basic security scenarios such as homes and warehouses, and an indispensable component of traditional security systems.
Electronic Locks:
Electronic locks are a product of technological advancement. Their core feature is the use of electronic components for unlocking. Compared to mechanical locks, electronic locks offer significantly improved security and convenience. Combination locks allow for quick unlocking with a digital password, eliminating the risk of key loss. Smart card locks support unlocking via card swipe or NFC on a mobile phone, making them suitable for use in scenarios requiring batch management, such as businesses and hotels. Biometric locks utilize individual biometric authentication for enhanced security. Electronic locks are widely used in corporate offices, hotel rooms, vehicles, and other areas, becoming a mainstream choice for modern security.

Fingerprint locks:
Fingerprint locks are a subcategory of electronic locks. Their core function is to unlock the door by recognizing an individual's unique fingerprint biometric. Due to the uniqueness and irreproducibility of fingerprints, fingerprint locks are extremely popular in the security field. They are widely used in residential homes, high-end apartments, commercial spaces, and other settings, representing a typical application of biometric technology in locks.
