While everybody is trying to bring a new coins with new shiny cool features, everybody is missing the simple fact that coin is for paying. So why nobody cares about simple feature, to allow buy things with a coin?
It would be simple like this:
A merchant will put up a qr code with a wallet address and price in USD/EUR on his merchandise. Customer has an app in his smartphone that will read the code and get the current price for the coin on the exchange. Then if he decides to buy, the application will transfer the amount to merchant's wallet. All done. Merchant will receive confirmation, buyer goes away with goods.
We already have a wallet for android don't we? So all we're missing is to put this QR code function in and an application that shows transactions and prints codes.
What do you people think?
