Apple’s iPhone 12 is quickly taking shape and one among the foremost surprising (yet consistent) leaks is that the return of an old favourite. And now we've an honest idea how Apple will roll in the hay.
Picked up by PatentlyApple, Apple has just won a patent which explains how its existing optical fingerprint reader technology (already utilized in the new 16-inch MacBook Pro) can tweaked to work under a display. In fact, Apple is pretty blunt about this writing within the patent:
“An optical image sensor is carried by the housing under the display. The optical image sensor senses biometric image data related to a user, such as, for instance, data representative of a biometric image of the fingerprint patterns of the user’s finger. The controller may perform an authentication function by matching the acquired biometric image data to the stored biometric template data stored within the memory.”
Apple also illustrates the patent employing a smartphone form factor.

So could all this just be future looking tech, as in many patents? It seems unlikely.
First, this is often an easy adaption of existing real-world tech. Second, Apple has been furiously filing in-display Touch ID patents for over an year. Third, Bloomberg is simply the newest during a long line of status sources stating Apple will reintegrate Touch ID into the iPhone 12 by fitting it under the screen.
Why would Apple need this when it already has Face ID? face recognition and fingerprint recognition have clear pros and cons (You got to check out it Vs you don’t; you'll use it with gloves on Vs you can’t, etc etc) but their greatest strength is when used together. This super strength security isn't necessary in the least times but it's helpful at crucial moments, like in banking apps. Apple also has plans to show iPhones into a sort of Digital ID, and here security must be rock solid.

All of which might simply be the icing on the cake for an iPhone which we already know will feature an upgraded design, 120Hz ProMotion displays, some incredible 3D camera tricks and, potentially, the top of the Lightning port.So while the iPhone 11 series already impresses, it's like 2020 are going to be the year Apple really takes its smartphones to a replacement level. Now the large question is will Apple really release SIX models?
