fingerprint-reading technology, the company said that ultrasonic sensors not only improve the accuracy but also eliminate the need for a capacitive sensor. Qualcomm markets this as the Snapdragon Sense ID 3D Fingerprint technology.According to a fresh rumor from China, the Xiaomi Mi 5 will be the first smartphone to make use of Qualcomm's ultrasound fingerprint recognition technology, one that's natively supported by the Snapdragon 820. Back in March, when Qualcomm announced the new
In essence, Qualcomm's ultrasonic fingerprint recognition tech can create a 3D map of your finger, complete with all the micro-ridges of your skin. Qualcomm says that the technology works well even with wet or dirty fingers, unlike current-gen fingerprint readers.
Although a more accurate fingerprint recognition system is definitely a nice thing to have, that's not where the story ends. What's particularly interesting about the new tech is that the ultrasonic sensor can recognize fingerprints through various materials, such as glass, metal, and plastic. This means that the tech doesn't require a capacitive sensor placed on the outside of the body. Instead, manufacturers can place the sensor behind the display, which could improve the overall ergonomics of the phone. It remains to be seen how Xiaomi decides to make use of the Snapdragon 3D Fingerprint sensor, but needless to say, we're pretty excited to investigate Xiaomi's implementation.
