Qualcomm has announced its second-generation ultrasonic fingerprint reader to deliver in-display fingerprint scanning. In its key comparison, the latest version spans a larger surface area and offers faster processing speed when it comes to unlocking the phones.
Precisely, the new Gen 2 3D Sonic Sensor measures 8mmx8mm. This makes it 77% larger than the Gen 1 that is 4mmx9mm in size. This means it will be easier to put your finger on the sensor. Also, the sensor will be able to collect more data with each scan for higher accuracy. As per Qualcomm, Qualcomm 3D Sonic Sensor will capture 1.7x more biometric data.
In the press release of the Gen 2 ultrasonic sensor, Qualcomm promises that scanning a fingerprint to unlock a phone will be 50 percent faster with the 3D Sonic Sensor Gen 2.
Technically, the Gen 2 ultrasonic sensor is the third in-display fingerprint sensor as Qualcomm also announced 3D Sonic Max in 2019. The latter was much larger in size even when compared to the former but it lacked real speed improvements.
Qualcomm has announced that the first phones to feature the new 3D Sonic Sensor Gen 2 should be available in “early 2021.” The company didn’t take any particular names but it is not hard to guess which phones they are going to be. Qualcomm’s first-generation ultrasonic sensor made its debut in the Galaxy S10 lineup of phones in 2018. So, it is expected that now the second-generation ultrasonic sensor will be featured in the Galaxy S21 series.
Samsung Galaxy S21 is scheduled to unveil on January 14 at the company’s special Unpacked event. Samsung has been the biggest consumer of Qualcomm’s under-display fingerprint sensors, so this year will continue to follow that as well.
