There are some interesting cards - I still didn't decide which one I will chose. These ones for example look interesting too:
Most of them implicate some obvious and/or hidden costs though. The one you presented is very interesting, too: thanks for your article.
By the way a steemit-card (!) which could be used to go to a cash dispenser and convert steems directly into your currency would be fantastic! :-)
Of course Steem card 💳 👍🏿
