If you’re following the recent iPhone 8 rumors, you might know that Apple is reportedly working to ditch its “Touch ID” fingerprint sensor in future iPhones and iPads, according to KGI analyst Ming-Chi Kuo.
Kuo believes that Apple will replace the current Touch ID sensors with two new options, including a new form of fingerprint reader and a separate face-identification sensor. The fingerprint sensor is supposed to exist under the display, the same also rumored to exist on the upcoming Samsung Galaxy S8. Apple may use technology from Synaptics that allows a fingerprint reader to exist, underneath the display. A user can then tap the screen to verify his or her identity.
However, it was also pointed out by Kuo that it is hard to place fingerprint sensors beneath the display, so Apple might get a hard time doing it, meaning that we might be or not be able to see it soon on iPhone 8, but for the future iPhones, as well.
Keep in mind that you must take this post with a pinch of salt. Also, TouchID is a branding, so Apple could keep that around even if it does swap out a home button for a fingerprint-reading display.
