Move Over Sense ID Fingerprint Technology Because Here Comes The Ultrasonic-Screen Finger Technology

Source: BGRIt seems that biometric advancements have today become the main prerogative of smartphone manufacturers. The next-generation Ultrasonic Under-Screen or Finger Print scanners were unveiled by Vivo in partnership with Qualcomm in the recently concluded Mobile World Congress 2017 held in Shanghai.

So first let us try to understand why the need for such kind of scanners gathered steam. As has been the trend this year, smartphone manufacturers tended to make smartphones with ultra-wide screens leaving no space for physical home button in the front. As a result, fingerprint scanners had to be moved backwards as can be seen in phones like Samsung S8 or the LG G6. But this led to handling issues as the phone needed to be picked up before it could be unlocked.

Vivo’s Ultrasonic sensor, as explained by, is an underscreen sensor, which is opposed to the previous generation’s capacitative sensors and it works by emitting ultrasonic sound waves that penetrate the skin of your finger and capture a precise 3D image of your fingerprint. Vivo further claims that its sensor can penetrate the glass, aluminium and OLED panel deeper and is not affected by ambient light, wet fingers or sweat marks. The sensors can further detect heart rate and blood flow and even work underwater allowing the smartphone easier to waterproof. The sensors are equally user friendly and to unlock the phone, the user only needs to register his fingerprint on a designated area of the phone screen.

Qualcomm in its press release has further announced that the Fingerprint sensors for glass and metal are expected to arrive in commercial devices in the first half of 2018, while the Fingerprint sensors for display are expected in the fourth quarter of 2017.

While there have been some noticeable concerns on the speed and accuracy of the underscreen sensors, we believe that the technology once perfected will lead to a much more efficient and smooth experience for next generation of smartphone users.
