Do you know whether any of the cards have shipped and are being used?

Of course, you can find the first card users posting on twitter.

There are also some video reviews of the first standard cards.

And the team posted their tests with the coming currencies like ETH and DASH too.

I don't know about the special cards issued with the ICO though.

Amazing, can't wait to get my hands on the card. The token price should rocket soon.
