A Revolution in Payment

In the field of digital payments, palm vein technology is revolutionizing the experience from "active operation" to "seamless access."

This is not simply "swiping your hand," but a high-tech system based on the unique "password" within each person's body. Palm vein recognition uses near-infrared light of a specific wavelength to illuminate the palm, acquiring an image of the complex distribution of subcutaneous veins. This vascular network, like the veins of a leaf, is unique from birth, even among twins, and is deeply hidden beneath the skin, making it impossible to see, copy, or steal. It must be a "living" body with flowing blood to be recognized; any forged model or severed hand is useless. It is this inherent uniqueness, internality, and liveness that lays the foundation for its extremely high security.

At a convenience store, with your hands full of items, you no longer need to fumble to unlock your phone and pull up a QR code. Simply swipe your palm over the sensor area, and the payment is completed instantly. This "media-free" payment completely frees your hands and redefines the boundaries of convenience. In high-frequency payment scenarios like rail transit, its advantages are even more pronounced. Taking the "palm-swipe gate access" pilot program in Shanghai, Beijing, Foshan, and other cities as an example, passenger throughput has significantly improved, effectively alleviating gate congestion during peak hours. The technology provider's goal is to enable citizens to truly "wave through," enjoying seamless travel without cards or mobile phones.

Both finger vein recognition and palm vein recognition utilize near-infrared light to penetrate the finger or palm, where it is absorbed by the hemoglobin inside, forming a shadow that outlines the distribution of veins within the finger or palm. Veins are located beneath the skin, and the vein network in each finger is unique to each person. However, the palm contains a much larger network of veins. Palm veins have a richer network and more feature information.

In 2023, the Beijing Subway Daxing Airport Line piloted the application of palm print biometric technology.

Access Control Evolution

Why have major brands been turning to vein recognition in recent years? From leading smart lock brands to palm vein security products across various industries, palm vein recognition certainly has its advantages.

Compared to facial recognition, fingerprint recognition, and the similar finger vein recognition technology, palm vein recognition is currently the most secure biometric technology. Secondly, palm vein recognition is a liveness detection method; only a living person can be captured by the device, eliminating the possibility of duplication and resisting common attacks such as those using photographs, thus better protecting user interests. Simultaneously, it is a non-invasive image acquisition method. The veins in the human body are hidden under the skin, with a complex structure and strong concealment, making them difficult to secretly copy and imitate, and extremely difficult to forge. When using palm vein recognition for identity authentication, the palm does not need to be in close contact with the device; simply placing the hand on the device completes the information acquisition task. Compared to fingerprints and finger veins, this method does not require contact with the device, making it more secure.

With the popularization of palm vein technology and the reduction in cost, more and more smart locks in homes are beginning to use palm vein recognition. Huawei's ecosystem has also launched palm vein recognition locks. Currently, the Shenzhen Metro is already using palm vein recognition technology. More and more access control and time attendance systems are now using palm vein recognition technology.

DEWO specializes in vein recognition technology, providing various palm vein and finger vein recognition modules, offering free SDKs and technical support. We also support customized palm vein access control machines and time attendance machines.
