Just moments after Apple lifted the wraps off their new flagship handset; we did a whole segment about its new feature called Touch ID which allows user to register their fingerprint and use that to unlock the phone. What we missed to point out, however, is that it can also scan other parts of the body including… nipples.

If you think that’s surprising (or amusing), wait till you here this. As it turns out, the structure of our nipples is as unique as our fingerprint. Therefore, if by any chance you registered your nipple using Touch ID and somebody tries to unlock your phone using theirs, then it’ll just be a futile attempt.

Don’t believe us? Well, here’s a short video courtesy of Rocket News:

In a separate video, one of the guys in the clip above also tried using his nose and toe on the scanner and it worked just as well. So if you’re planning to get the iPhone 5S and you think that your fingerprint isn’t secured enough, then we suggest trying to register different parts of your body to the Touch ID.

Apple has just officially announced the iPhone 5S earlier and one of its key features is its built-in fingerprint scanning technology called Touch ID. Read on to find out how it works.

Starting with the hardware, the Touch ID fingerprint sensor on the iPhone 5S is actually made of four main parts:

Laser-cut sapphire crystal – acts as a cover and lens for the Touch ID sensor
stainless steel detection ring – detects if your finger is on the home button
Touch ID sensor – the sensor that captures your fingerprint
Tactile switch

All of that is built right into the home button.

How does it work?

It all starts with the stainless steel detection ring which makes sure that your finger is on the home button. Without having to press, the 170 microns thin Touch ID sensor accurately (hopefully 100% all the time) scans the sub-epidermal skin layers of your finger with 360-degree readability at 500ppi resolution.

It is capable of reading multiple fingerprints which is then stored encrypted on the device and not on Apple’s servers or the iCloud.

What is it for?

Like most biometric technologies, the Touch ID is used for authentication purposes. Instead of using passcodes, the iPhone 5S can utilize the Touch ID and just scan your fingerprint which we all know is unique to yours. So in essence, Touch ID adds another layer of easy-to-use security to the iPhone which eliminates the cumbersome need to type a password whenever you need to unlock your device or make purchases on iTunes.

To sum it up, with the help of Touch ID, all you need is a finger… That is, if it works perfectly and you don’t lose your finger.

Editor’s Note: This isn’t the first smartphone to have a fingerprint scanner. In 2011, Motorola launched the Atrix 4G with the same fingerprint scanner. It never took off.
