Which is better, semiconductor fingerprint lock or optical fingerprint lock?

Advantages of Semiconductor Fingerprint Recognition:

1. The semiconductor fingerprint recognition module can only identify the living fingerprint, with high security, that is to say, the semiconductor fingerprint head can penetrate the ** surface hair layer, so the silicone simulated fingerprint that is prevalent on the Internet basically does not play any role here, and the advantage of identifying the living fingerprint lock is that the fingerprint basically cannot be copied or imitated.

2. Semiconductor fingerprint recognition is composed of tens of thousands of capacitors to form a capacitive array, collecting fingerprint ridges and valleys to form fingerprint data at the distance from the valley to the touch plate, which has better accuracy than optical scanning, can collect more accurate fingerprint details, and the collection speed is also faster.

3. The semiconductor fingerprint recognition module has a high recognition rate, and the optical fingerprint head will be affected by the dryness, wetness, and depth of the fingerprint in normal use, resulting in identification errors and the phenomenon of unable to identify fingerprints, and semiconductors can avoid these problems to the greatest extent.

In addition, it also has the advantages of low power consumption and small size, which is of great help to reduce the power consumption of smart locks and reduce the specific area of locks.

Deficiencies of semiconductor fingerprinting:

1. The capacitive version of the semiconductor fingerprint recognition module is obviously higher than the cost of the tempered glass of the optical fingerprint module, of course, the cost of other components is relatively higher than that of the optical fingerprint module, so the cost is higher, but with the development of the industry, the difference between the two is gradually becoming smaller.

2. The semiconductor fingerprint recognition module is not easy to maintain, and the collection window of the semiconductor fingerprint head will be affected by stains, sweat stains and static electricity, and it is easy to be scratched, so it is necessary to pay attention to protection and maintenance when using it, otherwise the service life is difficult to guarantee.

Advantages of Optical Fingerprint Recognition.

1. The environmental adaptability of the optical fingerprint recognition module is strong, and the optical fingerprint head collection window is generally made of tempered glass, which can enhance the compression, wear resistance and acid resistance to a certain extent, the corrosion of stains, the temperature adaptability to the working environment is good, and the surface is easy to clean, which can be used in the family, but also can be used in the special environment of humidity, high temperature and dust.

2. The optical fingerprint recognition module has good stability, the optical fingerprint recognition technology has been tested and continuously improved by the market for a long time, and the optical fingerprint head has good adaptability to the market environment, and has a long theoretical life.

3. The cost of optical fingerprint recognition module is low, the optical fingerprint head developed earlier, there is a mature industry scale, can be modularized and mass-produced, and the raw materials used in the optical fingerprint head are relatively cheap, so the cost of the optical fingerprint head is generally cheaper than the semiconductor fingerprint head.

Deficiencies of optical fingerprinting.

1.There are certain inherent defects in the recognition accuracy of the optical fingerprint head, the optical fingerprint head is the reflection of the fingerprint ridge and the valley to the light of different imaging, for the fingerprint shallow, the fingerprint is too dry or peeling users, it will be prone to the phenomenon of wrong identification.

2. The power consumption of optical fingerprint recognition is relatively large, and the optical fingerprint head needs to emit strong light, so compared with the semiconductor fingerprint head, it needs more electrical energy, and the general optical fingerprint lock needs to replace the battery once for more than half a year, and the semiconductor fingerprint lock can be used for a longer time.

Summary: Each has its own advantages and disadvantages, and you should buy it according to your own needs when buying.

Press your finger on the white paper and Indonesia to print it out, and each printed fingerprint can not be opened on the optical and semiconductor fingerprint lock, if the fingerprint is pressed on the silicone printed fingerprint and placed on the lock of the optical fingerprint head, the lock is successfully opened; The lock placed on the fingerprint head of the light conductor cannot be opened.

Is semiconductor fingerprint recognition a liveness recognition.

Which is better, semiconductor fingerprint lock or optical fingerprint lock? Semiconductor fingerprint lock and optical fingerprint lock, joint fingerprint lock will be a little more advanced, semiconductor fingerprint lock painting, after all, it has been many years.

The semiconductor identification module has a high cost, and only identifies the fingerprints of living organisms, which can prevent the theft of fingerprints and unlocking, with high security performance and relatively fast recognition speed; The optical model guide is relatively low, and the recognition of imaging pixels is also different, and the low pixel is lower, and the recognition rate, recognition speed, and security are lower than that of semiconductor mold guide.
