Apple just filed a patent for “identifying fingerprint signature” gestures. The patent describes how a future device will be able to detect which finger is touching the screen. This can be handy in for example screen gestures, where when more fingers are enabled, countless more gestures become available.

Many people believe this patent will be used in the iPhone, but they are wrong. When do you use more than two fingers on an iPhone? The device size is too small for that. You got it right…We are talking about a patent made for the Apple tablet here.

In addition the patent includes haptic feedback technology. When you touch the screen, you can feel where the on screen buttons are without actually seeing them. This will be useful for both the iPhone and the MacBook tablet.

The fingerprint ID can theoretically act as a security device so that only you can activate your phone.
