Qualcomm unveiled its new biometric sensors that work below the display. The second generation of the 3D Sonic has a larger usage surface and recognition speed grows by 50% compared to the first generation.
Furthermore, the first smartphone to use this new sensor would be very close. They would in fact be the smartphones of the family Galaxy S21, thanks to an agreement reached between the parties for the supply at the beginning of the year. Incidentally, the first generation has been used by a lot of other OEMs, including Samsung.
In addition to the surface and the higher speed there is more. The 3D Sonic Gen 2 will improve reliability and security so as to exclude problems related to possible identity theft or access to the smartphone with exploits. In technical terms, the surface that will recognize the fingers will grow from 36 mm² to 64 mm², reaching even more precision in the reading of biometric data.
Qualcomm says that recognizing the fingerprint will be very fast, thanks also to an algorithm that will scan and predict that the one supported is the corresponding fingerprint or not. Galaxy S21 will be the first to use it from a chronological point of view but a whole series of brands, which already used the 3D Sonic Gen 1, will be able to include it in their products. The new fingerprint sensor it will always be made with ad technology 3D ultrasound and Qualcomm aims to build a scanner that will reach and exceed the performance of a traditional physical one.
