Do not use fingerprint sensors Period

It depends. How about, do not use one step to verify/authenticate/authorise/etc - Period.

Biometrics is not a password, so it should not be treated as one. There are many good advantages of using fingerprint to do something where passwords would not be great. Take for example a public place - do you really want to enter your password/pin when somebody is looking? And with current levels of video surveillance somebody is always looking. I'd rather place my finger on my phone and unlock it. This goes with any method of authorisation - we should focus on making sure people are aware of their strengths/weaknesses, instead of using scare tactics saying something just doesn't work.
