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?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.
This is a great idea, but how will the situation with the use crypto-currency cards in those countries where crypto currency is banned?
They sould work in legal field. If cryptocurrencies are banned don't allow persons to spend money in this country. Regulators usually look at other countries expirience and then decide what to do in each situation. If digital assets will work all over the world, everything will be fine
Nevertheless, I think there will be countries where you can not use these cards while the crypto currency is banned there. On the Internet, you can find ways to bypass the lock and exchange your coins for the currency of the country where it is prohibited.
