Is any of this currently used in ID theft (other than residential location)? Earlobe shape isn't exactly a security question. Might screw them over in the future but hard to call this the full identity theft package.
Edit: I guess the other meaning is things like getting a duplicate SIM card to defeat 2FA. I'd imagine that's a problem. Can anyone comment whether such information would make this easier?
Yes:

Would the world with this system (and its inevitable leaks) be worse? What I mean is that replacing a system where e.g. knowing someone's mother's maiden name is enough to get you a SIM card, to one where you have to show up and have the same earlobes... even if, err, the earlobes leak, might be better?
Or does getting a SIM card involve an inside man, in which case maybe nothing changes?
It would be a bit stupid to base an identification system, like that of a bank or credit card or whatever, on earlobe shape or Iris alone. But in combination with other factors it might be quite secure.
I think Earlobe shape can be used for identification in video footage. Iris scans only if you have a really good camera and a lot of luck. Otherwise it's really hard.
