The video that shows how even a CAT can unlock the new iPhone 5S after its paw was used instead of a fingerprint Technology site wanted to test if any skin - not just human fingerprints - could unlock an iPhone 5S The cat's paw was registered as one of five safe Touch ID profiles Heel of palm and wrist were also able to unlock the phone's content It's been hailed as the safest smartphone on the market with its fingerprint recognition technology. And now the iPhone 5S has proved just how secure its new password service is, by registering a cat's paw print as a key to unlock the gadget. Technology site, TechCrunch, wanted to test the new Touch ID feature which allows the phone's owner and four other Touch ID profiles to unlock the phone using skin-recognition technology. VIDEO: The iPhone 5S cat paw test Video Source TechCrunch After a few false starts, the cat's paw was recognised as one of the owner's five chosen keys and was able to access the phone's content. The user was also able to use the heel of his palm and his wrist in the experiment which is described as 'a broadening of the definition of what counts as a "fingerprint"'. Though different parts of the body were able to be registered and then recognised as keys, when trying to fool the phone's software by using the opposite hand than registered access was denied. The experiment pointed out however that no other animals could be used to unlock the phone as cats have unique fingerprint like paws. Apple unveiled the fingerprint scanner on its iPhone 5S last week with bold claims about its high levels of encryption and security. TechCrunch wanted to test a theory that even animals could use Apple's new Touch ID feature. Amazingly, after a few false starts, the cat's paw worked and was able to unlock the phone repeatedly
