If we help Wirex it became first to had access to crypto MasterCard direct payment on pos. But at same time I can understand the fact of this block, time is very important and technology. The technology incorporated in the cards will allow to pay in the short future with bitcoin (contactless versions) and Wirex think want this fintech!!!. And what you would do, w8 new technology or using hold but fast and when new went out need another time change all cards. W8 MasterCard give the tech to Wirex or it will be anti-partnership.
