After ditching Touch ID with the iPhone X in 2017, Apple is possibly looking at bringing back the sensor with its 2021 iPhones. Reputed analyst Ming-Chi Kuo believes that the 2021 iPhone will feature both Face ID and an under-display fingerprint scanner.
Apple is currently facing a lot of technical issues in getting both under-display Touch ID and Face ID to work together. However, he is optimistic that most of these issues would be resolved by the time the 2021 iPhone nears its launch.
Some of the issues with the under-display Touch ID sensor include poor yield rates, size of the recognition area, power consumption, and more. Apple will implement under-display Touch ID and Face ID in such a way on its 2021 iPhones that they work together and offer a high-quality experience for which the company usually strives for.
Right now, while many Android smartphones do come with an under-display fingerprint scanner and face unlock, the experience offered by them is not that good. Apple has likely set a higher bar for itself which is why it is taking its own sweet time in introducing an under-display fingerprint sensor to the iPhone lineup.
Apple has filed a number of patents regarding the under-display fingerprint scanner in recent times.
The analyst believes that Apple will likely rely on Qualcomm’s ultrasonic fingerprint scanner for its 2021 iPhone. Samsung currently is the only OEM which uses Qualcomm’s under-display fingerprint scanner on its flagship devices. Other OEMs rely on an optical fingerprint scanner which is faster but does not offer the same level of security.
Kuo also believes that if Apple ended up implementing any kind of biometric authentication on the Apple Watch, it would be in the form of an under-display fingerprint scanner instead of Face ID. Nonetheless, he does not make any claims whatsoever of Apple launching an Apple Watch with any kind of biometric security. This makes sense as well since biometric authentication on the Apple Watch would not really be useful.
It is possible that Apple could use the under-display Touch ID sensor on the 2021 iPhones to reduce or completely eliminate the notch.
The TrueDepth camera system takes up a lot of space at the front which has prevented Apple from reducing the size of the notch. The company is rumored to reduce the size of the notch on its 2020 iPhones but not eliminate it fully.
What do you think about Apple adding an under-display fingerprint scanner along with Face ID to its 2021 iPhone?[Via 9to5Mac]
