The Iphone 5S is a product made by Apple Inc. It is now the latest Apple product. Most of the designs remain the same but the home button now uses a fingerprint recognition. This is the first 64 bit A7 processor. Lastly it has a larger aperture which will make all pictures that is taken more clear.
