libfprint provides two operations - verify and identify

verify asks you to use a specific finger and check against it, while identify 
gets a fingerprint and tries to match it to any sample in the set

see (slightly archaic) http://www.reactivated.net/fprint/api/

how this is handled in fprintd I have no idea, sorry
