Cards of the Round Table

Hey, look what came to my address a few days ago:


And this isn't a fake card, as far as I can tell -- it had an activation sticker on it.

What kind of company sends out a real credit card (or to be more precise in this case, a debit card that looks like a credit card) to a nonexistent person? Because it is a debit card, I suppose it has no risk to the company, but still... how did they get this name and connect it to my address?

Or maybe it's some weird promotional tactic, mailing cards like this to fans of Arthurian myth?
