Exactly that would be fairly similar to what i was proposing with this. Not that the merchants would accept crypto but that the app would instantly convert crypto to fiat for payment to the merchant. That way We could use our STEEM to pay the app which pays the shop.

I think that we are still a long way from using crypto straight so until then there will need to be a go between for purchasing as they all run off so many networks and systems. That is why Coinpayments would be a good option for online shopping and this would be an option for in place transactions.

They also have a quick point of sale in the app so a merchant could easily set up a small tablet at the register to accept payments in person.

This sounds interesting as it is taking on the same idea just from a different angle with the tablet doing the conversion rather than the app. Thanks for the input.
