It wouldn't have to be native to iPhone, I just would like to be able to us my iPhone, or any other smart phone, to tap into my restaurants POS to bypass writing down an order on paper and then re-entering into the computer. I would think I could skip a step and take the order on my phone and tap into the POS network and send my order to the kitchen. Seemingly I'd need a programmer to write an app or make a web based app to do this? I think if a generic app could be written to accomplish this there would be a huge market for restaurants to buy it, but what the fuck do I know?
