Ah I see, so basically the cards would hold tokens inside of them and if they are bancor tokens they could be swapped to one another and swapped out through exchanges like any other token?
are Bancor tokens working with any ERC20? or do we need to create a whole new line of tokens?
Thats right,
as for Bancor, they work with any ERC20 token, they just created extra functionality for their new tokens but you could use old ERC20 tokens as reserves for example.
