Features of Fingerprint scan lens
The fingerprint authentication (or recognition) technology is one of biometric identification technologies and used for security or personal identification by utilizing the characteristics of each one.
This is a lens for scanning such fingerprints.
In particular, for the fingerprint authentication lens, we managed to develop and is mass-producing the lens for large areas, which can scan the whole surface of moist palms.- Purpose : fingerprint authentication
- For use with cameras : Area camera
- For use with cameras : 1 ~ 5 generation
