Qualcomm’s New Ultrasonic Fingerprint Sensor Introduced With Enhanced Features


To design a full-screen smartphone, the manufacturers have to use innovative technologies. The under-screen fingerprint sensor is one of them. Due to it, the phones could reach a higher screen-to-body ratio.

This technology not only provides safe, reliable, fast recognition and a futuristic portable unlocking experience, but also satisfies users’ pursuit of larger, more complete, and more beautiful screen vision. Thanks to the mentioned characteristics, under-screen fingerprint recognition is the most popular and recognized unlocking solution currently.

Qualcomm 3D Sonic Max ultrasonic fingerprint sensor

Today, Qualcomm once again talked about the 3D Sonic Max ultrasonic fingerprint sensor. The new generation is larger in size, supports two fingerprints, ensures a faster operation, and is more secure.

When reading the last sentences, many users will have complaints. We mean this technology fails to operate because of sweat, moisture, oil, dust, etc. But the thing is that the Qualcomm 3D Sonic Max ultrasonic fingerprint sensor perfectly avoids these problems. The company has upgraded it in terms of recognition, entry, security, and convenience.

More Accurate Recognition

Qualcomm’s 3D Sonic Max ultrasonic fingerprint sensor uses the evolving ultrasonic technology to read 3D features such as the ridges, grooves, and pores of the user’s fingers. In effect, it will form very accurate fingerprint images. Even when the finger is wet, the Qualcomm 3D Sonic Max ultrasonic fingerprint sensor can penetrate the surface of objects such as glass and metal for accurate fingerprint scanning.

Larger Area

That’s not a secret that one of the most important features of fingerprint recognition sensors is the operating area. The larger it is, the more efficient experience we get. Sometimes even if it deviates from 1-2 mm, it may cause a slower unlocking or even failure. Qualcomm’s 3D Sonic Max ultrasonic fingerprint sensor has a large sensing area. According to the official introduction, it is 17 times larger than the original product. This simply means that the sensor can collect a large amount of biometric data instantly. And it only takes 0.2 seconds to unlock the phone.

Double Fingerprint Recognition

Thanks to the large recognition area, Qualcomm’s 3D Sonic Max ultrasonic fingerprint sensor also supports the simultaneous reading of two fingerprints. It will enhance the security of payment and other applications. But there is another application it should mention as well. Parents can set certain applications to be unlocked with dual fingerprints. So children can only unlock the phone with the participation of their parents.

Ultra-Thin Design

Qualcomm’s 3D Sonic Max ultrasonic fingerprint sensor also uses a 0.2mm ultra-thin design. Thus, it won’t affect the phone’s thickness.
