root@Zotac:~# fprintd- fprintd-delete fprintd-enroll fprintd-list fprintd-verify Which reader do you regard as the premium one? Right now I am using a Digital Persona 4000 but it more often than not cannot match the user. In this case, 15 mismatches and 5 correct matches. See below. I guess the reader is just of a too poor quality and would like to buy a good one instead.
