Quite. It'll be a little hardware black box that nobody can see into, one that just gives a 'yes' or 'no' answer.
Additionally -- if things are like they used to be when I was in the biometrics world in the mid-90s -- the fingerprint template will be small and work like a one way hash; if you have the template you cannot reconstruct the fingerprint from it. It wouldn't really be very useful to the NSA or anyone else.
