iPhone 8 may have Touch ID on the side

The latest cover images and concepts that appear on the internet all follow the same line, bigger power button and no fingerprint sensor on the back cover. Has Apple managed to put the function on the Display of it?

Rumors about Apple's next phone are evolving as more is discovered and the date approaches. There are now several designs that seem to follow the same line. On the back of the device there is no place where the fingerprint can be placed, the only visible difference is the change in the orientation of the camera's sensors, from horizontal to vertical. The front is almost entirely made up of the screen, but there is a slight difference in the power button. This one is substantially longer, which has led several people to believe that the button may now incorporate the Touch ID function.
