What are the advantages of the ultrasonic fingerprint scheme of Samsung Galaxy S 10 compared with the traditional off-screen fingerprint?
In addition to finer patterns, ultrasonic fingerprints can also obtain information that fingerprints under the optical screen do not have. Ultrasonic fingerprint can detect the blood flow in the finger, and judge whether the fingerprint information is true or not through this information, so as to prevent being deceived by fingerprint mold or broken finger and improve the security of fingerprint detection. In addition to higher security, the better penetration of ultrasound allows it to obtain clear fingerprint information even when the fingers are dirty and wet.
Fingers can also be unlocked with water. In addition to better security and wider use, the special principle of ultrasound also makes fingerprint identification play a more special role. For example, ultrasound can penetrate the skin and can be used as a heart rate monitoring device. Of course, this requires special design and software support.
It can be said that Samsung, which uses the fingerprint under the ultrasonic screen, has wider environmental adaptability, higher security, speed and recognition rate than the traditional fingerprint under the optical screen. In the future, mobile phones with off-screen fingerprints will be divided into two camps: optical and ultrasonic. Samsung, which took the lead in adopting Qualcomm's under-screen ultrasonic fingerprint, has overtaken it on the curve of the under-screen fingerprint avenue, occupying the technical high ground.
