This service it intended to identify computers by their unique MAC addresses as well as other characteristics. It can be used to customize and control web pages depending on the logic connected to the identification of the computer. For the identification the service uses Java in combination with JavaScript.

First of all, use this service for free but on your own risk! It is still under development and may be subject to changes or inconsitencies.
Any page that need access to the client's computer ID simply has to include the following HTML code:
<script type="text/javascript" src="http://www.deadbytes.de/track/id.js"></script>
Then the client's computer ID and its MAC addresses are available to other scripts in your page. You can access them as JavaScript variables as shown below.
<script>
<!--
// work with the given ID inside your page, e.g. customize or log data
document.write("MAC 0: "+ _tr_macs['0'] +"<br>");
document.write("found ID: "+ _tr_id +"<br>");
-->
</script>
You can view the example here.
