I am not in a position to need a card just yet, still need to earn some crypto first!
But if you have some knowledge maybe you can suggest some "cards" or apps?
In Australia Coinjar looks like one of the few available.

"tap & go" or paypass is fairly common here with a normal FIAT based visa plastic, use of mobiles for that is growing slowly. A ref doc of something would be great if you (or someone) could help start one.
At the moment my "reading list" on all this crypto & steem is huge but I'm plowing through it as fast as I can! :-)
