In recent years, the application scope of face recognition has become more and more extensive, such as ordering and paying, entering and exiting the community, handling business, etc. Paying by face has become a new model and integrated into people's lives.

But recently, WeChat Pay and Alipay have released the latest news about palm payment. On March 28, the appearance patent applied for by Alipay for a palmprint recognition device was authorized.On the same day, WeChat launched the 2023 WeChat Open Class PRO·“ "WeChat Appointment", "WeChat Palm Payment" was introduced to the public for the first time in public.

I believe someone will ask, it is also biometric technology. Now that we have face payment, why do we still use palm payment?

Compared with the current domestic face-based payment, palm-based payment has obvious advantages. First, identical twins are highly consistent in appearance, and it is easy to make mistakes when scanning their faces. The biometric characteristics of brush palm recognition have obvious differences and can distinguish identical twins with a low misrecognition rate. Second, palms are more private and concealed than faces, and your face may have been "stolen" inadvertently. Third, although masks are no longer required in many places, most people are accustomed to wearing masks when traveling. In addition, in special scenes such as hospitals, it is very inconvenient to take off masks.

At present, there are two main types of palm swiping in China: palm print recognition and palm vein recognition. Palm print recognition is to identify the identity by identifying the palm image from the end of the finger to the wrist. The palm features for identity recognition include main lines, wrinkles, small Texture, ridge ends, bifurcation points, etc.

Zhangtongtianxia uses palm vein recognition technology, which uses the characteristics of hemoglobin in human blood to absorb near-infrared light to obtain palm vein images. Palm veins are the veins faintly visible through the skin of the palm, including all venous systems within the palm. The hemoglobin of red blood cells in veins is reduced hemoglobin that has lost oxygen, and reduced hemoglobin absorbs near-infrared rays.

Compared with face and palmprint recognition, the biometric characteristics of palm vein recognition are hidden under the skin. The vein structure is complex, the possibility of being secretly copied and imitated is low, and it is very difficult to forge. And due to infrared rays and the physical characteristics of the human body, only living bodies can be captured by the instrument. The vein image features cannot be obtained from non-living palms, making it impossible to identify and fake. Compared with other biometric identification technologies, it is safer and more efficient.

Therefore, even with face recognition, we still have to launch palm vein recognition technology, and will continue to research and innovate on this, and strive to promote it, so that palm vein recognition technology can gradually penetrate into daily life and let more people feel the palm veins The convenience brought by technology.
