Whether Apple will actually be able to implement this radical new technology has been the source of a heated debate. Apple could follow the trend and put the fingerprint sensor on the back of the iPhone.
What's Apple doing differently? Face and iris scanning has existed in phones for a while - I tested ZTE's smartphone implementation of eye scanning back in March 2015 - and Samsung's Galaxy S8 has both iris scanning and face scanning as a way to unlock the phone. Interestingly, this security feature can even work if the iPhone is lying flat on the table, and not just close to the face.
KGI Securities analyst Ming-Chi Kuo has also provided predictions for the upcoming OLED iPhone 8 and updates to the iPhone 7 and iPhone 7 Plus. The 3D is said to improve security, too, by collecting more biometric data than Touch ID and reducing the chances that the scanner would be fooled by a photo. Adding to this long list, there is another one that says that Cupertino giant is working on a feature that will let users unlock iPhone using their face instead of a fingerprint.
Bloomberg also reports that Apple Inc. introduced the fingerprint scanning Touch ID system in 2013 for the iPhone 5s.
Apple iPhone 8 is supposed to launch this September, along with iPhone 7s and iPhone 7s Plus. Technologically, the feature draws on more information than the fingerprint-reliant Touch ID, which makes it more secure and it can also log a user into their phone within a few hundred milliseconds. Since then it has spread across nearly all of Apple's devices, and can now be used for features including payments and logging into specific apps.
For the analyst, the option chosen by Apple should be 3D detection for facial recognition. The interesting question is if Apple gets the fingerprint scanner, where will it embed it, if there is no home button.
Kuo likewise believes that the iPhone 8's wireless charging capabilities will not be available by default and will only be enabled by an optional accessory that will be sold separately.
