What's happening in the field of biometrics? Is it ever likely that I'll be asked to speak my name out loud and that'll work as reliably (from the user's perspective) as a password? I've always thought, perhaps irrationally, that the problem with biometrics is false positives: i.e. letting in someone who isn't you. I misttype my passwords all the time, and I think users would be OK with a "Sorry, can you say that again?"-type message on occasion. Basically, am I in "where's my flying car" territory?
