  • You do realize that PHP runs on a server, and a print scanner is going to be attached to a client machine? Unless the scanner dumps the digitized print into a form field or something, there's no way for PHP to talk to it directly. – Marc B Feb 08 '12 at 12:19
  • @MarcB you can run PHP on 'client' machine as well. _But the question is too vague anyway, as there numerous different ways do do that._ – c69 Feb 08 '12 at 12:21
  • every device has its own SDK, you want me to utilize that sdk, and then update my app database at the end of the day? – Khan Feb 08 '12 at 12:22
  • Marc B and c69 are just saying that there are several important questions that you haven't answered that need to be before a sensible answer can be made. Does SUPEREMA come with its own software, or does it have any open-source software available, or does it have a plugin framework? There are some easy ways to get data from one app to another, but they're very contingent on circumstances. – A. Wilson Feb 08 '12 at 12:30
  • SUPEREMA comes with its own software. – Khan Feb 08 '12 at 12:38
  • Does that software has a documentation, an API reference, something? – Damien Pirsy Feb 08 '12 at 12:41

It looks like the SUPEREMA system does have a SDK

http://www.supremainc.com/eng/product/pc_22.php?mark=33

However it doesn't integrate with PHP. The only way I can see of doing it would be to write a Visual Studio app that captured and updated to the database, or one with an embedded html browser that it could then send the captured data to.

Suprema includes now a Web Agent API with its SDK.

The Web Agent they provide is a Windows-based application that acts like a mini-web-server on the client side on a specific port. e.g., https://localhost:5151.

When a client visits your web application and they have the Web Agent up and running, you can do a cross-origin AJAX request with the help of Javascript to https://localhost:5151/scan that would return a base64 encoded image of the fingerprint.

Basically what they have done is to bridge the web browser to the internals of the client's computer.
