Amusing little tidbit from TechCrunch:
I tested a colleague’s hypothesis that you could register the identifying skin segments of your favorite furry friends for Touch ID, too.
The cat’s paw worked, and while it encountered more frequent failures than did a fingerprint, it was able to unlock the phone again repeatedly when positioned correctly on the sensor. Note that no other paw pads would unlock the device, and that cats essentially have unique “fingerprints” just like people, so this doesn’t make the Touch ID sensor any less secure.
I wonder if a rabbit’s foot would work?
