With the recent opening of the Hard Rock Bristol Casino in Bristol, VA it appears Hard Rock International has now switched to a universal UNITY slot card program with the same card to be used at all locations. So far the card have only been reported from the new Bristol casino so I'll wait to add links to the other Hard Rock Casinos as they switch over. I've created a new Hard Rock International casino management entry for the new universal cards.

Here's a scan of the ICON level that is actually between the blue and black cards level wise. Plus there are images of the other levels from the casino website.
