Apple announced that its new iPhone 5S features a fingerprint sensor called Touch ID, calling it "the most secure phone" on the market.
The fingerprint sensor allows users to unlock the iPhone 5S thanks to biometrics without having to type in that annoying four-digit passcode.
Yes, it looks like the Cupertino company is finally making use of its $356 million AuthenTec purchase, and it's doing it in style.
The fingerprint sensor has a 500ppi resolution on scanner and 360-degree readability, according to Apple, so you don't have to orient your finger every time.
The new home button sensor itself is 170 microns thin and it scans Scans sub-epidermal skin layers. It blends right into the now-blank home button.
Even more interesting is that the stainless steel detection ring of the fingerprint sensor knows your finger is there - meaning you don't have to actually press down on the button anymore.
Beyond unlocking the iPhone 5S, users can make iTunes purchases through the phone's fingerprint sensor.
The latest iOS software may be required, as Apple said the sensor is deeply integrated with iOS 7.
Apple didn't discuss whether or not other app developers in its App Store will include ways to bypass passwords using the fingerprint sensor in the future.
There's also the question of how the fingerprint sensor is going to work with third-party accessories such as cases that would normally cover the iPhone 55 home button.
