Qualcomm's new larger 3D Sonic Sensors touted to scan fingerprints 50% faster

Qualcomm's new larger 3D Sonic Sensors touted to scan fingerprints 50% faster

Qualcomm is ploughing through with ultrasonic fingerprint-sensing technology as it introduces its second-generation 3D Sonic Sensor. The chip, set to go out into smartphones in the extreme near0future, features a reading surface that's 77% larger than the original and better processing that should result in 50% faster scans. However, something that hasn't been addressed here and has been challenged multiple times is the reliability factor.

Qualcomm's new ultrasonic fingerprint scanner is 17 times bigger than last year's

Qualcomm's new ultrasonic fingerprint scanner is 17 times bigger than last year's

Qualcomm announced its new "3D Sonic Max" fingerprint scanner at the company's annual tech summit this morning, and the biggest improvement is, well, that it's big. The new version of the ultrasonic sensor is allegedly a full 17 times larger than the previous generation, measuring 30.6x19.2mm. In standard measurement, that's around .91 square inches, about equal to the surface area of the coin face of two pennies.

That's much, much larger than most existing fingerprint scanners in smartphones, ultrasonic or optical, and should theoretically result in far fewer bad reads, as the area in which you can place a recognized portion of your finger is greatly expanded (think of it as shooting an arrow at a bullseye the size of the whole target).

Why Samsung using ultrasonic tech for the Galaxy S10's in-screen fingerprint scanner matters

Why Samsung using ultrasonic tech for the Galaxy S10's in-screen fingerprint scanner matters

Samsung has just announced its latest super-duper flagship phone, and among the new features it boasts is the world's first commercial ultrasonic fingerprint sensor under a display. We've seen other in-display scanners on phones from the likes of OnePlus and Huawei, but they use optical technology instead. This new ultrasonic method is supposed to be better in more ways than one — let's take a look at why.
