fingerprint device with own characterization system?
<p>I want build a fingerprint control access in Java. I have a device to get a thresholded fingerprint image and I do some image processing, but I get a high rate of error.</p>

<p>My question is, exists a fingerprint sensor device with its own characterization system?. I mean, the device takes a fingerprint and its output is a serial number or an characteristics vector, not a image, I dont want to do a image processing system to do this.</p>

<p>With this data characteristics is very easy to get a degree of similarity between fingerprints and decrease my rate of error, but I dont know if in the market exist that kind of device.</p>

<p>I appreciate a lot if you guys help me to choose what to do, buy a magic fingerprint device or continue with my image processing system.</p>

<p>Thanks a lot.</p>
