Technological innovation continues. From traditional key and password access control to biometric access control, each upgrade has improved security and convenience. Among them, the application of palm vein recognition machine in the field of access control is becoming a new trend in the industry and leading the technological trend.
Palm vein recognition technology is a recognition technology based on human biological characteristics. Its principle is based on the absorption characteristics of near-infrared light by hemoglobin in the veins of the palm of the human body. When near-infrared light irradiates the palm, the hemoglobin in the veins absorbs part of the light, thereby forming a unique venous image on the imaging device. The image contains rich vascular pattern information, such as the thickness, branching, and intersection of the blood vessels. These features are unique and stable, just like everyone's fingerprints. Through advanced image processing algorithms and pattern recognition technology, the system can accurately extract the characteristic information of palm veins and compare it with the templates pre-stored in the database to achieve accurate identity recognition.
Compared with other biometric technologies, palm vein recognition technology has significant advantages. Although fingerprint recognition is widely used, it is easily affected by the surface conditions of the fingers, such as dryness, moisture, wear, stains, etc., which may lead to recognition failure. Face recognition is more sensitive to lighting conditions, facial expressions, and posture changes, and the recognition accuracy will decrease in complex environments. Palm vein recognition technology, because it recognizes the venous characteristics inside the palm, is not affected by the surface conditions of the skin, and the vein characteristics are hidden in the body, which is difficult to be forged or stolen, and has higher security and stability.

In access control systems, security is the primary consideration. Palm vein device uses liveness detection technology to ensure that only real live palms can pass recognition. This is because blood flow in veins is an important feature of living bodies, and only living palms can present normal venous images under near-infrared light. In contrast, traditional access cards are easily lost, stolen or copied, and passwords may be forgotten, leaked or cracked. The false recognition rate (FAR) of palm vein recognition technology is extremely low, usually less than 0.001%, which is almost negligible, providing a rock-solid security guarantee for the access control system.
In places where people frequently enter and exit, such as office buildings, schools, factories, etc., the recognition speed of the access control system directly affects the efficiency of personnel passage. Palm vein recognition machine has extremely fast recognition capabilities. In 1:N (one-to-many) mode, when N is equal to 2000 IDs, the recognition speed is less than 0.3 seconds; in 1:1 (one-to-one) mode, it can complete recognition within 0.2 seconds. This fast recognition speed allows people to quickly pass through the access control without waiting for a long time, greatly improving the efficiency of passage and avoiding congestion caused by queuing.

In addition to recognition speed, recognition accuracy is also a key indicator for measuring the performance of access control systems. The rejection rate (FRR) of palm vein recognition technology is less than 0.01%, which means that even in complex environments, the system can accurately identify the user's identity and rarely misjudges. Whether in strong light, backlight environment, or when the palm is slightly stained or slightly worn, the palm vein recognition device can work stably and accurately identify the user's identity, providing strong support for the reliability of the access control system.
Access control systems usually need to operate in a variety of different environments, so their environmental adaptability is crucial. Palm vein recognition device uses advanced optical and image processing technology and can adapt to a variety of lighting conditions and temperature and humidity environments. Under natural light (sunlight), the light intensity during registration must be less than 2000 Lux, and during recognition must be less than 3000 Lux; under fluorescent light, it must be less than 2000 Lux for both registration and recognition; under incandescent/halogen light, it must be less than 500 Lux for registration and less than 700 Lux for recognition. Its operating temperature range is between -10℃ - 60℃, and its operating humidity is between 10% - 90%. It can operate stably in various indoor and outdoor environments and is not affected by harsh environments.
In corporate office areas, especially some company headquarters, financial institutions, scientific research institutions, etc. that have extremely high requirements for information security and confidentiality, the palm vein recognition access control system can effectively prevent unauthorized personnel from entering. By combining with the company's human resources management system, it can not only realize employee attendance management, but also accurately control their access rights to different areas according to their positions and permissions. For example, in important areas such as the company's finance room, R&D room, and server room, only authorized specific personnel can enter through palm vein recognition, which greatly improves the internal security and management efficiency of the company.
In the construction of smart communities, the palm vein recognition access control system provides residents with a more convenient and safe access experience. Residents only need to place their palms on the recognition device to quickly open the door, without having to carry access cards or worry about forgetting passwords. For visitor management, community managers can generate temporary palm vein access rights for visitors through temporary authorization. Visitors can enter the community through palm vein recognition within the authorized time, and the access records can also be traced. At the same time, the liveness detection function of the palm vein recognition device effectively prevents safety hazards such as fake certificates and duplicate cards. With the cloud alarm system, it can realize real-time warning of abnormal access and escort the safety of the community.
As a place with dense population, safety management is crucial. The palm vein recognition access control system can be applied to school gates, teaching buildings, libraries, dormitories and other areas. In terms of student attendance, attendance is carried out through palm vein recognition, which eliminates the phenomenon of punching in for others and improves the accuracy of attendance. At the same time, according to the student's grade, class and other information, the system can set different access rights to ensure that students can only move in the specified area, ensuring the safety and order of the campus. In addition, for faculty and staff, the palm vein recognition access control system also provides a convenient way to enter and exit, improving the overall management efficiency of the school.
In medical institutions, especially in some areas with high requirements for infection control and safety management, such as operating rooms, intensive care units, and drug warehouses, palm vein recognition access control systems play an important role. Medical staff can quickly enter the work area through palm vein recognition, avoiding the risk of cross-infection caused by contact with traditional access control equipment. At the same time, strict authority management ensures that only authorized personnel can enter specific areas, ensuring the safety of the medical environment and the confidentiality of medical information.

With the increasing demand for safety and convenience and the increasing maturity of biometric technology, the palm vein recognition access control system market is showing a rapid growth trend. According to data from market research institutions, the global palm print and palm vein recognition terminal market size will be approximately 10.63 billion yuan in 2024, and is expected to be close to 31.73 billion yuan by 2031, with a compound annual growth rate (CAGR) of 16.9%. In the Chinese market, it will account for a certain proportion of the world in 2024 (assuming 20%, about 2.126 billion yuan), and the subsequent annual growth rate is expected to exceed 20%.
In the future, the palm vein recognition access control system will develop in a more intelligent and integrated direction. On the one hand, with the continuous development of technologies such as artificial intelligence and big data, palm vein recognition terminal will have more powerful data analysis and processing capabilities, and can realize real-time monitoring and analysis of personnel entry and exit behaviors, providing more valuable decision-making basis for security management. On the other hand, palm vein recognition technology will be deeply integrated with other intelligent devices and systems, such as video surveillance systems, intelligent alarm systems, property management systems, etc., to achieve more comprehensive and efficient intelligent management. At the same time, in order to meet the personalized needs of different users, the palm vein recognition access control system will continue to optimize product design and user experience, and provide more diversified functions and services.
