McDonald's will have QR codes on their packaging/bags that you can scan with your smartphone to get nutrional 411 on what you are eating. "The QR code is in addition to the nutritional information McDonald's currently prints on brochures, tray liners and more as well as on the information that can be found on the company's apps."
Good Idea? I like the idea, but not sure I want to know the nutritional value of a Big Mac, fries and a chocolate shake. I realize they have salads, grilled chicken/sandwiches and apple slices, but do most go to McDonalds for that type of meal?
