When fingerprint scan is captured, matching should be done to check if the fingerprint was already captured.

      This is tricky because it depends on proprietary solutions running on the browser side.

      Do you already know what kind of fingerprint scanner are you going to use on the user machine?

        The scanner is secugen. What i want to achieve is this. I will capture the finger template, Run a database query and get already existing finger template on database. then I will use the matching algorithm to match for duplicate. I am looking for a class to do the proper matching or best way to do the matching on the finger template

        This is tricky because the solutions I have seen are very device specific, and very browser specific.

        The most standard thing I have seen is a WebUSB specification that could allow for you to access a USB device from JavaScript.

        This is very recent, so it seems to be a experimental feature in Chrome 51 and there is a patch for Firefox in evaluation.

        Even when such browsers support it, you would need to know what to send or receive to that fingerprint device, so you can send it to the server for interpretation.

        Only after knowing the format of the fingerprint capture you could do anything with PHP.

        So for now, I think you need to rely on device specific solutions from that vendor.

        If you do not know how to proceed, you may want to post a job offer, maybe somebody capable can help you.

      It does not makes sense. Implementing a fingerprint reader requires a deep analisys of the fingerprint patterns, which nowadays there are a ton of laser ones. All they do is output a unique number for every read, so, essentially, the logic behind it is more suitable for hadware than software.
