If you already have one, I'm not sure that you can. When we got our's, we had to sign up for it directly through the DVC web site. Maybe you should call Bank One and ask if it's still possible?

It`s funny we`re going through the same thing right now. We recieved the Disney Visa card through a different invitation, and after having the card for a month or so, we noticed that the DVC website (and vacation magic magazine) had the invitation with "DVC Member" on the card, as well as 40 Disney reward Dollars for applying. (All of which, we didn`t get!)
We called Bank one the other day about this matter, and they said they would get back to us. You might want to call also, I hope the least they might do, is send us new cards, even if its sans the reward dollars!
My Disney Visa says "Charter Member" on it. I asked one of their most excellent customer service reps about getting DVC Member put on, and she told me that they would simply need to print a new card (same everything else). But I don't think I'll bother until the current card expires.
