In modern society, the demand for security and convenience in residential and commercial spaces continues to grow. Traditional mechanical locks present numerous limitations in security, management efficiency, and user experience that fail to meet contemporary requirements. With the rapid development of IoT technology and the proliferation of smart home concepts, smart locks have emerged as innovative access control systems that are transforming how we secure our properties.

Smart locks integrate electronic, mechanical, and biometric technologies to provide access control through multiple authentication methods including passcodes, fingerprints, facial recognition, IC cards, and mobile apps. Compared to traditional locks, they offer superior security, easier management, and smarter user experiences.

Key smart lock categories include:

• Keypad locks: Operated via preset numeric codes
• Fingerprint locks: Utilizing biometric fingerprint scanning
• Facial recognition locks: Advanced biometric authentication
• IC card locks: Ideal for apartment buildings and hotels
• Mobile app-controlled locks: Remote access via smartphone
• Hybrid models: Combining multiple access methods

The evolution of smart locks spans several decades:

• Early stage (1970s-2000): Basic keypad and IC card systems for commercial use
• Development phase (2000-2010): Maturation of fingerprint technology
• Rapid growth (2010-present): Integration with IoT and AI technologies

The global smart lock market has experienced significant growth, with projections indicating continued expansion through 2028. Key growth drivers include increasing security concerns, smart home adoption, technological advancements, and supportive government policies.
