Apple’s iPhone 5s started reaching customers on Friday, and since then users around the world have been getting to know the handset’s impressive Touch ID feature. Though promoted as a fingerprint sensor, however, it would seem that Touch ID can read more than just a human fingerprint.

In a series of videos brought to our attention by 9to5Mac, Touch ID is shown to work with a nose, a toe, and a nipple (don’t ask).

Here are the videos, see what you think:

As a reminder, Touch ID uses a fingerprint to unlock an iPhone 5s, to complete iTunes, App Store, and iBookstore purchases, and to access services such as Find My Friends. The sensor reads the living fingerprint underneath the dead, outer layer of skin on one’s finger to provide an accurate reading for users.

Have you been using Touch ID this past weekend?
