Fingerprint not reliable #20

Closed frlacf closed 6 years ago

frlacf commented 6 years ago

Hi, first of all, thank you for your great work.

Concerning the problem, I find the reader very unreliable, I did the fprint-enroll about 20 times and still can't get a single match with fprint-verify. I think the problem come from the fingerprint reader itself: it is not made for a ''Swipe'' finger identification. The size of the reader (about 1cm by 1cm) makes it more appropriate for ''single scan'' authentication.

I might be wrong though.

have a nice day and continue your great work !

Francis

Hi Francis, this is a known problem and unfortunately not much can be done at this point.
