title: PHP controlling a finger print device
body: <p>I have to control access to a system based on fingerprint recognition in <code>PHP</code>.
  But I do not know what would be the best approach to do this...</p>
  
  <p>I was searching for a device and software, and maybe this will the one I'll use:</p>

  <p>This software use somekind of SDK, so java must be used, Is there a way to make a bridge between <code>php</code> and <code>java?</code>.</p>
  
  <p>I am not expert in java web services, but if this is the only way, How to control fingerprint?</p>
  
  <p>Does the device returns an <code>image</code>, or a <code>md5 string</code>, or How does it work, how to read this in php?</p>
  
  <p>What is your experience in this kind of thing...</p>
