1. The optical fingerprint recognition module has strong environmental adaptability.
2. The optical fingerprint recognition module has good stability.
3. The cost of the optical fingerprint identification module is low.
Disadvantages of optical fingerprint heads:
The recognition rate of fingerprint images with coverings on dirty and dry fingers is very low;
Poor adaptability to environmental factors such as temperature and humidity.
There are often traces left on the surface of the acquisition window.
Advantages of semiconductor fingerprint head:
1. The semiconductor fingerprint recognition module only recognizes living fingerprints, with high security.
2. The semiconductor fingerprint identification module has very high sensitivity and identification accuracy.
3. The recognition rate of semiconductor fingerprint recognition module is high. The optical fingerprint head will be affected by the dryness and wetness and depth of the fingerprint during normal use.
Disadvantages of semiconductor fingerprint heads:
The cost and cost of the semiconductor fingerprint identification module are relatively high.
The semiconductor fingerprint recognition module is not easy to maintain, and the wear resistance is not enough. thereby affecting its lifespan.
