The new fingerprint sensor is much more secure than the traditional face unlock technology. Most smartphone makers these days are using the face unlock technology in their phones. The fingerprint technology used by Samsung and other brands uses optical sensors to take a photo of the user’s fingerprint for verification. Qualcomm’s new sensor removes the fingerprint reader and uses ultrasonic reader underneath the display which allows smartphone makers to stretch the display across the entire front of the smartphone.
The existing 3D Sonic Sensors have drawback of its own. Reviewers explain that these sensors have slow unlock speeds, which results in error if the finger is not placed on the exact right spot. Earlier this year, Samsung users reported that anyone can unlock the Galaxy S10 smartphone. The silicon screen protector reduces the accuracy of fingerprint verification.
Alex Katouzian, senior VP and GM of mobile at Qualcomm said, “What we’ve done is collected and bought [with Samsung] multiples of these phone covers, and we’ve created anti-spoof algorithms that are already released into the market. There’s nothing wrong with the fingerprint sensor design.”
Qualcomm is also working on a larger under-display fingerprint sensor. Which offers an eventual goal of becoming a sensor that works across the entire display. It is rumoured that the next generation of iPhones will feature this fingerprint sensor that feature full-screen TouchID.
