They have already confirmed in this topic about the cards, when the goal will be achieved. The important thing is with which company they will make partnership for cards.
Why is it important? Is there a big difference with who makes the card?
Yes, it is very important. For example, you can see adv cash and other wallets like these, they are only available in the EU, because they have a partnership with one company that does not allow cards for another countries.
You are right! The best variant for Datarius is partnership with Visa/Mastercard (they plan to realize this after $5 mln collected funds). Would be great to spend digital coins all around the world without any barriers.
