Here’s an interesting patent. While hype and rumor has suggested that when Apple introduces a fingerprint sensor in the iPhone 5S, it’ll be placed under the home button, Apple’s actually patented something much different: technology that would allow an iPhone to detect your fingerprint just by pressing your finger against the screen.
This makes a lot of sense. Not only is it a more elegant place to put a fingerprint sensor — and Apple loves elegance — but it explains the redesigned iOS 7 lock screen, and the way ‘Slide to Unlock’ has been de-emphasized. We’ll see!
