That's an awesome idea. For it to be successful they'll either need one of the big credit card names involved or they'll have to get a major company like Amazon or Walmart to accept the new card as payment. You might be able to target some kind of a niche audience and go for a smaller market but the card wouldn't go near as big.

I'd love to see something like this happen but I think they have some major hurdles to clear to make it work. If it does happen I'd get one though.
