Qualcomm introduced the second generation of ultrasonic fingerprint sensor. With its growing size and increasing speed, the 3D Sonic Sensor Gen 2 is more functional than the first generation.

Qualcomm announced the latest version of the ultrasonic in-display fingerprint sensor, 3D Sonic Sensor Gen 2, to correct the disadvantages of the first generation in-display fingerprint sensor and to improve the sensor. Qualcomm’s 2nd generation ultrasonic fingerprint sensor offers a larger surface area, more biometric data capture, and improved performance to unlock phones faster.

50% faster data processing compared to first generation
3D Sonic Sensor Gen 2 measures 8mm x 8mm compared to the first generation sensor’s 4mm x 9mm surface area. The 77% enlarged surface area will allow users to scan fingerprints more conveniently. The larger surface area during use means it will be easier to place your finger correctly on the sensor.

Thanks to the new sensor, users will be able to unlock the smartphone using the on-screen fingerprint scanner, even when the smartphone is wet.

According to Qualcomm, the 3D Sonic Sensor Gen 2 can collect about 1.7 times more biometric data than the previous generation and can process fingerprints about 50% faster than the previous generation. The sensor is only 0.2mm thick, making it thinner than the previous generation.

Qualcomm’s first-generation sensor, known as the 3D Sonic Sensor, launched in 2018 in the Samsung Galaxy S10 flagship smartphone series. 3D Sonic Sensor Gen 2 is also expected to be available with the Galaxy S21 series, which will be introduced on January 14.
