Apple's Touch ID on the iPhone 5S can do more than just read fingerprints. In fact, it can read more than just human skin!

TechCrunch tried out the sensor on a cat's paw and successfully unlocked the device. The paw would have to be programmed to the iPhone 5S for access of course.

The Touch ID sensor reportedly works on other parts of the human skin, too, including the palm of the hand and forearm.

In related news, a group of hackers and security researchers have pledged to reward the first successful hacker to find a workaround to the fingerprint sensor with $13,000.

A Wall Street Journal report last week revealed that if you leave your iPhone 5S untouched for 48 hours straight, you won’t be able to use the device’s fingerprint scanner to wake it up. Instead, you'll need to resort to the more traditional method of plugging in your passcode.
