This latest patent covers a fingerprint scanner that's separate from the circuit that processes the print, so it can be placed under the screen.
Fingerprint readers have been included in laptops for a while now, as a way to secure your computer and ensure only you can unlock it. Apple's interest is also said to be to use the fingerprint scanner to verify your identity and make secure transactions through your iPhone 5S.
The inclusion of a fingerprint scanner has been one of the more persistent rumours surrounding the, iPhone 6 or whatever it's going to be called. I can't see it myself -- it just doesn't seem very Apple.
But the signs point that way: Apple last year.
As well as the iPhone 5S, Apple is reported to be planning a cheaper plastic model, probably clad in a selection of colours and possibly called the iPhone Light.
