</div><div><br></div>Hello Martin<div><br></div><div>Please let us know how it will work. You wrote you need identification, so verification (ready to use fprintd-enroll and then fprintd-verify) will not help you / will not enoug for you.</div>
<div><br></div><div>I'm also searching for sollution where only fingerprint is needed (no keyboard needed, no user name berofe scanning is needed. I think it could be called pfrintd-identify.</div><div><br></div><div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi,<br>
<br>
I am currently working on a unit where I need fingerprint identification<br>
of up to 50 users. The system is going to run on Linux (right now with a<br>
Raspberry Pi as host) which is why I use libfprint. Installing/compiling<br>
newest libfprint (from the git repo) has been done.<br>
<br>
I have good experience with the UPEK touchstrip sensors, however in<br>
multiuser environments I have the feeling that, first of all the number<br>
of false negatives are a bit high, probably mostly due to how small the<br>
sensor is, thus increasing the risk for people to make an "erroneous"<br>
swipe. I feel that for an application to use fingerprint, for people to<br>
not get "pissed" at the system, it must be rather stable.<br>
<br>
Therefore I am calling for some experience regarding the different<br>
readers supported by libfprint regarding to stability and ease of use<br>
(for the user), before I just start randomly buying readers :)<br>
My best guesses right now are the URU4500 and EikonTouch 300 (are the<br>
500/510's supported?) since they use "touch" type which I guess would be<br>
easier for the user, and give more minutiae easier, but this is more a<br>
guess, since I only have experience with the touchstrip versions.<br>
<br>
Any help is appreciated!<br>
<br>
Kind regards,<br>
Martin Hejnfelt<br>
