I don't think there are any working cards that accept customers from all parts of the world at the moment though. If you're from EU, US or UK, then you should look into Coinbase, Bitpay, or Wirexapp.
Man thanks for this thread link. There are so many projects which are working through the payment processors so that we can enjoy best of both the world. After looking at the list which is really big one, I started feeling to own one card at least which is based on bitcoin to fiat payment directly. @Ratimov has done really amazing job by listing our all the cards available on the internet. I think I already fit into few of the system demographic way and can avail them easily. Thanks for the list.
