View Full Version : Fingerprint Scanner that outputs hash

01-24-2010, 09:06 AM
Hey all,

I've got no idea if this exists or not. If it doesn't I'll give you a shiny nickel to invent it for me.

Basically I'm looking for a fingerprint reader that operates like your typical magnetic card reader. You swipe the ID and the reader outputs that hash into the computer's active text area and then sends the return key event.

Do you know of any fingerprint scanners that output a unique hash to a local text field?

In case you are wondering why I would need such an odd device for web development: I'm working on a psuedo-intranet which I think would benefit better in the password department by using some fingerprint magic coupled with SHA-2.

Thanks for any information you can provide!

I would guess it would work like this ...

You have a fingerprint scanner, like these:

The scanner has software that reads the print and outputs a code just as
though it were typed on a keyboard. On a web page, the cursor would need
to be put into the correct textbox before the finger was scanned. The textbox
would be filled-in like a password with asterisks ******

Basically, the scanner emulates keyboard input ... and I think that's what those
various scanners do. In any case, each PC would have to have the driver and
software for converting the fingerprint binary code to an ID/password of some kind.

Joe ...
Yeah, this forum is about discussing coding, not for putting your links on
here in order to get "ranking" ... that's spamming, and you're not welcome here.
Hopefully, the moderators will remove your URL and your post.
