Ultrasonic Fingerprint Scanner can now be found in premium smartphones of OnePlus, Oppo and Realme. At present, two types of biometric technology are used for security in smartphones. The phone has face unlock as well as fingerprint sensor. Talking about in-display fingerprint sensor, there are two types of it, one is optical and the other is ultrasonic fingerprint sensor. Most of the smartphones launched in India come with optical fingerprint sensor.
Oppo, OnePlus and Realme, all three technology companies belong to the same group and they will now use ultrasonic fingerprint scanner instead of optical in their flagship smartphones. Chinese tipster Digital Chat Station (DCS) said on microblogging site Weibo that premium smartphones of these companies will now have ultrasonic fingerprint sensors. Ultrasonic fingerprint scanner is used only in Samsung’s Galaxy S series flagship smartphones. Come, let us know what is ultrasonic fingerprint sensor and how is it different from optical fingerprint scanner?
What is Ultrasonic Fingerprint scanner?
This is also a kind of in-display fingerprint sensor, which unlocks the smartphone based on sound waves. Samsung first used this technology in the Samsung Galaxy S10 series. This amazing technology works on the basis of waves emanating from users’ fingers, which is safer than existing optical scanners. The waves emitted from the ultrasonic fingerprint scanner map the design of the raised stripes in the fingers and unlock the device.
As soon as the user places his fingers on the ultrasonic fingerprint scanner, the sound waves emitted from it bounce back to the sensor and identify the fingers. This technology is more expensive than the existing optical sensors, due to which it is used only in flagship smartphones. The special thing about this technology is that even if there is oil or anything else on the fingers, there is no problem in unlocking the phone. Its waves work to unlock the device with the help of 3D mapping.
However, if the wrong screen protector or screen guard is installed on the ultrasonic fingerprint scanner, then it can become difficult to use because the screen protector can create an air gap between the scanner and the fingers, which can create problems in 3D mapping. Could.
