If you’re lucky enough to have one of the first iPhone 5S phones, you’ll have a fingerprint sensor built-in to the Home button. This fingerprint sensor lets you lock an iPhone 5S to your fingerprint and the fingerprints of several other people as well who you trust (or at least hope you can trust).
To show how accurate the iPhone 5S’s fingerprint sensor can be, someone has tested the sensor with a cat’s paw. Now you can assign your cat as a trusted user of your iPhone 5S. Just make sure your cat doesn’t sneak off with your iPhone 5S to call a 900 number to talk dirty to other cats, or order food deliveries when you’re not home.
