And it's SO EASY, to paraphrase Pogue's description:
All you need to do is figure out which finger activates the phone, somehow get a good clean print of that finger from somewhere, print that onto transparency film without inverting it, then take that film and use it to expose some copper clad photosensitive PCB board, develop the image on the PCB using special chemicals, put the PCB through an etching process to wash away all the exposed copper, and then create a fingerprint mold, which you can then use to open the phone if the owner hasn't already bricked it remotely in the hours that you've been hard at work doing this.
Apple is such a joke. This is totally going to happen ALL THE TIME!
(Read the hacker's account, it's pretty interesting. As he says, "Hacking TouchID relies upon a combination of skills, existing academic research, and the patience of a Crime Scene Technician.... Practically, an attack is still a little bit in the realm of a John le Carré novel.")
