Swipe your palm to open the door is more popular – Smart Door Lock Biometrics Upgrade

Brush your palm to open your home – vein recognition technology, which is friendlier to special groups such as the elderly and children, is becoming a new favourite for smart door locks.
China’s smart door lock market is maintaining steady growth. The 2024 China Smart Door Lock Industry White Paper, jointly released by the China Hardware Products Association and other organisations, shows that over the past year, China’s all-channel retail sales of smart door locks are expected to reach 20.2 million sets, up 8.0% year-on-year.
The penetration rate of smart door locks is rising rapidly. in 2020, the market penetration rate of smart door locks in China was only 14.5 per cent, while by 2024, the figure has climbed to 27.9 per cent.
The technological development of smart door locks is one of the key factors driving the market growth. in 2024, the application of biometrics in smart door locks is further popularised, with technologies such as face recognition, fingerprint recognition and vein recognition, in particular, becoming the mainstream in the market.
As the earliest biometric technology applied to smart door locks, fingerprint recognition still dominates the market. in 2024, the output and sales volume of fingerprint recognition module is expected to reach 25 million sets, accounting for 96% of the market. Although some high-end products are beginning to abandon the fingerprint recognition function, its popularity in the low-end and mid-range market is still unshakeable.
Fingerprint locks are unlocked by recognising the fingerprint pattern. Despite the uniqueness of fingerprints, for the elderly and children, their fingerprints are often not as clear or perfect as those of adults, which can easily lead to recognition errors or failures.
Vein recognition technology, an emerging biometric technology, shows strong growth in 2024. The market acceptance of finger vein and palm vein recognition technologies is gradually increasing.
Among them, finger vein recognition uses near-infrared light to irradiate the finger, and haemoglobin absorbs the light to form a unique vein image for unlocking, effectively avoiding the security risks associated with traditional fingerprint recognition due to fingerprint abrasion, smudging, or copying.
Palm vein recognition technology is derived from the security system, through infrared light scanning palm vein blood vessel image for unlocking, recognition distance up to 15 to 35 cm, recognition speed less than 1 second.
It can be said that the high security of the vein recognition technology and the friendliness of the elderly, children and other special groups, making it an important development direction for the future smart door lock market.
Meanwhile, the market share of face recognition smart door locks has increased significantly. technologies such as 3D structured light and binocular infrared have become the mainstream solutions for face recognition, especially in the high-end market, where the application of face recognition technology has been further enhanced.
In addition, with the diversification of consumer demand for smart door lock functions, multifunctional combinations have become a mainstream trend in the market. 2024, the functions of smart door locks are no longer limited to simple unlocking, but are integrated with cat’s-eye, indoor screen, multi-camera, and other security functions, which further enhances the added value of the product. 2024, the market share of cat’s-eye smart locks exceeded 50%, and it has become the standard function of smart door locks. . Through high-definition video streaming transmission, users can view the dynamics of their home at any time and communicate with visitors remotely, improving home security.
