The Hardware Key is a mobile platform for your software license, allowing the same license to be used on different computers.
For example, if you have your Motive setup on one computer, but use Motive for editing motion capture data on another computer, you can simply move the Hardware Key to the workstation you are using at the time.
If you are purchasing a hardware key for an existing system, please review our licensing faq or contact support before proceeding.
Also, please view the Software Compatibility Chart to confirm compatibility.
