Scientific and technological developments in the future, we no longer have to worry about forgetting your password does not take money, lost his identity card lead to information disclosure. Because our hands are passwords and can prove identity. This is the biometric technology, living human identity card in the 21st century.
In today's world, identification is becoming more and more important in everyday life. Whether you go to the bank for business, or you fly by plane, or even open a door, you need to verify your identity. Traditional authentication methods include identification, such as documents, keys, user names, and passwords. With the help of foreign substances, once a token or password is stolen or forgotten, its identity is easily impersonated or replaced by others.
The non-contact palm recognition system uses the person itself to prove the identity. It uses the uniqueness of the human features to be non-replicable, and it is difficult to capture fingerprints, palm prints, human faces, and irises that people are familiar with. It is copied, the palm is easy to peel, injury, face shape instability, the requirements of the environment light source and other factors, through the active irradiation of the near-infrared light source, the use of human hemoglobin to absorb specific infrared light characteristics, to obtain infrared image of the human subcutaneous vein network.
The system uses an embedded processor and a multispectral image acquisition device as its core hardware. It has a dual-object image sensor and multi-spectral imaging technology. It has high-definition palmprint capture, and palm subcutaneous vein dual-body biometrics and biometric authentication. Its non-contact acquisition method completely overcomes hidden dangers such as fingerprint leakage and hygiene problems brought by series of contact biometric identification products such as fingerprints, and has the advantages of being portable and available everywhere. In the demo system, the database stores the features of the palm of the hand of 500 people. Visitors only need to reach out and identify the system. The system can identify the visitor in only one second.
The non-contact palm recognition system is exquisitely designed and can be widely used in electronic transactions such as access control attendance, ATM deposits and withdrawals, and online banking. It can also be used in hotel applications such as hotel registration, customs clearance and outbound management, etc. Traditional identification methods such as passwords and IC cards. According to user requirements, it can provide a single point or networked multi-point access control system that divides physical security areas, which greatly improves the overall community safety and reduces the occurrence of criminal events. As a high-precision identification product, the contactless palm recognition system is closely related to our life and work.
The non-contact palm pattern recognition product adopts high-performance embedded processor to collect, process and identify online. The authentication is fast and accurate, and the comparison speed (1:N, N<100) is less than or equal to 1.5 seconds. At the same time, the unique dual image sensor and dual-band spectral imaging technology are adopted to simultaneously acquire palmprint and palmar vein image analysis and recognition, greatly improving the accuracy of single feature recognition, and introducing palmar features, with traditional biometric products. There is no living authentication feature that can be used for high security level identification occasions.

Precision alloy, is a kind of alloy owning special physical properties (such as magnetism, electrical, thermal and other properties).The vast majority of precision alloy is black metal based, only a few is based of nonferrous metals. It usually includes magnetic alloys, elastic alloys, expansion alloys, thermal bimetal, electrical alloy, hydrogen storage alloys, shape memory alloy, magnetostrictive alloy and etc.
In addition, in practical application some new type alloy are also considered to belonging into precision alloy, such as vibration damping alloy, stealth alloy, magnetic recording, superconducting alloys and microcrystalline amorphous alloy and etc.
