[Help] Physical YuGiOh Card Game player ID, and how to register it.

I own a physical Konami ID card with its code, never activated it. One like this:

I also have a digital Konami ID for Duel Links and Master Duel that also has its own code.

I want to use the unregistered ID in tournaments, as the mobile internet I own is too weak to load the website properly and in a timely matter. But I cannot find a way to bind this physical ID to my account, without creating a new one.

How do I bind this card to my account, or how do I request a physical Konami ID card for my current account status?

Or maybe you suggest to have a clean Konami ID account for tournaments?
