The home button isn’t making a return to future iPhone models but there is a possibility that Apple’s exploring a way to incorporate an in-screen fingerprint reader. According to popular TF International Securities analyst, Ming-Chi Kuo, Apple might be prepping an iPhone 2021 model that will provide support for not just Face ID, but Touch ID as well. Since all future iterations are expected to feature OLED screens, it will become simpler for Apple to use under-display fingerprint scanners, and if we’re lucky, the sensors at the top of the iPhone’s display used for facial recognition might somehow be embedded beneath that display.

Kuo predicts in a fresh report that Apple is attempting to unify the biometric experiences of both facial and fingerprint recognition. The company has filed numerous patents related to this, meaning that there’s a chance a future iPhone model might provide support for both security features. One reason why Apple didn’t want to settle with an in-screen fingerprint scanner when its competitors were launching devices in droves with this option was mainly due to how slow the authentication process in comparison to traditional fingerprint readers.
