Do I need the National Dex to be able to download the Member Card?

[McKnight]

I just found out about the Member Card event that's going to take place in just a few days. I do understand that one does need the National Dex in order to access the place it unlocks. However, I only got as far in Pokemon Platinum as I needed in order to unlock the wi-fi feature and download the Secret Key, and I've been saving the rest of it for some point after I complete Pokemon Diamond.

If someone will answer me, do I need the National Dex in order to download the Member Card, or will unlocking wi-fi be enough for it?

Yes. It says so in this link that was provided in this thread. It would also have been appropriate to ask in the "Simple Questions" thread.
