It's not Mastercard or Visa you deal with directly, you go to an issuer to make the cards. I could make a Mastercard that says "cumbucket" on it and still not even talk to mastercard.
Issuer's are licensed by Visa or Mastercard to issue cards. You could make prepaid cards through an issuer and many have done that before. But, that isn't what the roadmap promised. It made specific mention of you putting Coino into an account and then as the transaction happens it converts and pays.
To accomplish the roadmap, you would need to be an issuer. That does mean dealing with Mastercard and having a substantial volume. When all the Coino in the world is worth $25,000USD it going to be hard to raise the application fee.
I suggest you just call up Mastercard and become an issuer. The world will beat a path to your door when you do.
Let me know how that goes for you.
