Smart lock palm vein or finger vein is better

1. Smart lock palm vein is better. Palm vein recognition technology is a biometric-based identification technology, which is more secure than traditional password, fingerprint and other identification technologies. Due to the complexity and uniqueness of the palmal veins, it is difficult to forge or copy, so it can effectively prevent identity impersonation and fraud.

2. It is recommended to choose finger vein. Because the advantages of finger vein and palmar vein are: fast recognition speed, high accuracy, convenient user identification, and large capacity. It is mostly used in prison access control, mine attendance, shipyard attendance access control, government buildings, banks and other places.

3. The battery life will be reduced, so it is still being improved. Palm vein unlocking palmar vein unlocking technology is a patented unlocking method exclusively developed by the Yougu intelligent lock brand. It uses the unique veins of the finger for identification to perfectly overcome the problem that the fingerprints of the elderly and children are weak and cannot be recognized, and the trial population is further expanded.

4. In fact, these two methods are similar. The acquisition range of the palm vein is larger and the data is more accurate; the collection range of the finger vein is small, and the data is prone to deviation, but the finger vein is slightly cheaper and the equipment is smaller. So, it depends on your needs.

Introduction to palm vein recognition

It is safer than palm print and fingerprint recognition; it is more stable than face recognition;It is more universal than iris recognition.

Palmal vein recognition technology is a biometric-based identification technology, which is more secure than traditional passwords, fingerprints and other identification technologies. Due to the complexity and uniqueness of the palmal veins, it is difficult to forge or copy, so it can effectively prevent identity impersonation and fraud.

High level of safety protection: palmar vein recognition is to use the distribution image of human palm veins as biometric identification. It has unique characteristics and is basically impossible to be copied without contact, and residual information will not be collected, so the safety performance is very reliable.

Vein recognition is divided into: finger vein recognition and palmar vein recognition. Because the palmar vein has more venous images preserved and compared, the recognition speed is relatively slow.Finger vein recognition, due to its large capacity, fast recognition speed, high accuracy, live recognition and other advantages, is increasingly favored by more important occasions.

Sthaler, the provider of the technology in London, said that vein recognition technology is currently the safest biometric technology because it cannot be copied or stolen. It is worth noting that this payment method is not the fingerprints on the surface of the finger, but the veins under the skin.

The function of the palmar vein identifier is roughly to remove the fake and preserve the real, which is also the fundamental reason why all biometrics have been developed. The palmar vein identifier is a product of the information age and one of the products that people urgently need high security.

The unlocking methods of smart door locks are changeable. Do you know how many?

Compared with the traditional mechanical lock single key unlocking, swipe unlocking has the advantage of non-reproducibility, and the security is also fully guaranteed. The most common application scenarios are hotels and offices, and at present, the smart door locks on the market are equipped with special cards to facilitate users who like to swipe to unlock.

Personally, I think wisdomThe unlocking methods that can be locked are nothing more than those, such as fingerprint, password, Bluetooth, mobile phone app, face recognition, iris and so on. Whether there are hundreds or thousands of smart locks, their unlocking methods are the same. But what really makes a difference is the security performance of smart locks.

Unlocking method. Unlocking methods generally include fingerprint unlocking, password unlocking, mobile phone unlocking, card unlocking, face recognition, etc. In addition to face recognition, most smart door locks will have the previous unlocking methods. As for face recognition, if you have this function, the price will be higher, mainly depends on whether there is such demand.

The development trend of palm vein recognition

1. Therefore, people hope for a safe and confidentiality method with better confidentiality, higher reliability and more convenient - palm vein recognition technology was born.

2. The development prospect of palm pattern recognition technology is very good, but due to the relatively immaturity of technology and the current market situation, the formal implementation of palm pattern recognition technology still has a long way to go.

3. It is said that it is faster than face swipe payment and iris payment. It can complete identification and payment in about one second. In the test, it shows the fastest speed of 0.3 seconds.
