I read that announcement on medium, and actually can't believe how stupid that sounds! "Here is an app where you can connect your cards and use mnx on the platform. We dont know when are we sending card or is it even work"
Cards are not yet delivered, but as I can see now, that cards are gonna be just normal plastic card with qr code of your wallet printed on it. And they are gonna get away with it, they will deliver cards and they can be used.
