Login form with finger print reader

has anybody ever done authentification with a finger print reader and PHP? I am interested in using a finger print reader for a system I am developing, however I am not sure if that is possible. Any ideas on how to accomplish this?

Thanks a lot!

You'd have to write software for a fingerprint reader to send the data to a server. And then somehow process the data. Good luck.

Most physical devices ship with the device drivers, etc...basically these devices (ie: barcode, finger print scanner, etc) return the results as ASCII charatcers as though you entered them into a text box, at which point you would need to submit the form and handle the characters.

I would assume that a finger print scanner would return an indivuals finger print as some kind of hash code that was unique to that individual.

It should be trivial to implement, assuming the device drivers and everything are shipped with the product. Your best off contacting the manufacturer and asking them how it works.

As alex said, it's a matter of integration against specific implementations. You should research the common format used to capture fingerprint information and how you can parse those. Than it's a matter of having the user transmit this information to your site somehow, which could be more problematic
