Does fingerprint biometrics mean someone has a stored a copy of my fingerprint? Isn’t that a privacy concern?

A fingerprint biometric is not a privacy concern.  In fact, it is very privacy friendly because it is making sure no one can pretend to be you.  Also it is not typically based on storing you fingerprint.  It is based on calculating a numerical value created from unique features present on everyone’s fingertips.  When you touch a fingerprint scanner that number is recreated and compared to the original to confirm a match.  The whole fingerprint does not need to be stored.
