Qualcomm’s second-generation in-screen 3D fingerprint scanner optimizes the first-generation model in all the right places.
Qualcomm It introduced its first fingerprint scanner on display in December 2018. At CES 2021, the company launched its second-generation model, which is a huge improvement. This improvement was in great demand, as optical sensors from competition became very good over time. The company’s second-generation 3D Sonic sensor is available, and we’ll see it up and running soon, as the first phones come equipped with it. We decided to award the Qualcomm 3D Sonic fingerprint scanner one of our awards at CES 2021.
Unlike fingerprint scanners, which come with a small camera built in, Qualcomm’s 3D Sonic units work in a completely different way. It relies on ultrasound to scan your fingerprint, and it is more technically advanced than its optical counterparts. Qualcomm’s 3D Sonic fingerprint scanner scans 3D features such as bumps and valleys as well as your finger pores, in order to provide an extremely accurate image
Qualcomm introduced a much thinner and much improved 3D Sonic fingerprint scanner this time
Qualcomm’s 3D In-Screen fingerprint scanner is extremely thin. It is only 0.2mm thick, which should make smartphone manufacturers happy. These small units do not take up much space inside smartphones, and this is very important. This sensor is much larger than its predecessor in terms of scanning area. To be more precise, it’s 77 percent larger than the Gen 1 product.
The Qualcomm 3D Sonic Gen 1 sensor was 4x9mm (surface area 36mm2). On the other hand, the second generation model will offer an 8 x 8 (64 mm2) sensor. This will make it much easier to wipe your finger, as there is less room for error here. This is not the only change. This thing can capture 1.7x more biometric data compared to the first generation model, which is impressive.
It is much faster than its predecessor
One of the most important features of the fingerprint scanner is its speed. This, along with accuracy and safety, is the most important. Well, you’ll be happy to know that the second-generation Qualcomm 3D Sonic fingerprint scanner is 50 percent faster than its predecessor. This is also the latest news on the information Qualcomm has decided to share with the public when it comes to this product.
Optical versus ultrasound
The vast majority of smartphone OEMs have been using fingerprint scanners since their launch. Samsung has already used Qualcomm’s 3D fingerprint scanner, though, in nearly every flagship smartphone since its release. Well, it remains to be seen if more OEMs will adopt Qualcomm’s second-generation product, as it is expected to be a significant improvement.
It will definitely be interesting to see what happens, as the ultrasound fingerprint scanners are more technically advanced. If it introduces a second-generation 3D Sonic fingerprint sensor, many OEMs will have to include it in their smartphones. Samsung will likely be the first in the Galaxy S21 series, as this announcement came just in time for the Galaxy S21 launch.
