How to fetch Finger Print using javascript(client side)

Question

Answer 1

You can't access a USB peripheral directly through javascript or HTML as it is not included in any standard API. If there is a signed java applet available for it which exposes certain events and methods you could interface the javascript with the java applet to achieve some level of interaction but there is no way to achieve it through a strictly javascript/html manner.
