Second generation Qualcomm fingerprint scanner: faster and covers more area – Qualcomm suffered a lot of criticism when its first-generation 3D ultrasonic fingerprint sensor lacked, reliable accuracy and even phones were unlocked using unauthorized fingerprints. To address this problem, the United States-based company is preparing to reveal the enhanced 2nd generation ultrasonic fingerprint sensor with an expanded sensor area and a faster response rate. Compared to optical fingerprint readers, ultrasonic devices have a superior advantage in terms of accuracy and reliability.
Samsung ended up becoming the first phone manufacturer to incorporate Qualcomm’s 1st generation fingerprint sensor into its core devices, such as the S10 series. Unfortunately, being the first ultrasonic sensor, it did not work in the best way, as it used to unlock the device with anyone’s fingerprint. However, the problem arose mainly when the screen was covered by any screen protector.
As a solution, Samsung released some updates that solved the authentication problem to some extent. In the meantime, Qualcomm launched a larger version of its first-generation fingerprint sensor, the 3D Sonic Max, which covered a massive area of 20mm x 30mm. Although the 2nd generation ultrasonic fingerprint sensor does not land in a spacious accessible area, it certainly takes unlocking speed a step further.
Samsung remains one of Qualcomm’s key partners when it comes to using its ultrasonic fingerprint readers on its premium phones, which not only double the speed but also make them unique in their own way.
Technically, the most recent 2nd generation sensor measures 8 mm x 8 mm. On a good note, this under-display component is made in order to gather up to 1.7x more biometric information comparatively. In addition, it takes a 50% leap towards speed, which is quite fabulous. This will increase market competition, which should compel companies to bring better settings on their smartphones.
