The .cards namespace is managed by Donuts, and as usual with them, no particular purpose of the gTLD is specified - it is wild card. On the one hand, the .cards extension can hold a catalog of birthday cards - for free or sale. On the other hand, the .cards domain is perfect for a gift cards online department of any company - to offer discounts on products and service. On the third hand, if you would, the .cards namespace can host poker or gambling sites.
