Almost inevitable that this one will be baked, so better type fast.
In Japan QR codes are already appearing on food items to either describe the nutritional information or direct to a web page that describes the same. (wibni bit: a url variant should also be an xml file holding a standardised nutrition
data packet).
Just add mobile phone app to manage your diet.
Mode: Shopping
Phone says what you can and can't eat, based on alergies and dietry requirements.
Mode: Eating
Phone tots up what you're eating and displays running totals of energy, fat, mono, poly, crackers etc.
Your home recipe system will also oblige by showing a QR code on the screen for the meal portion you are preparing.
In this case probably carbohydrates and high in Omega 3.

Have it tattooed on your belly and monitor the dimensions to see how well your diet is going. |
|
| |
e.g. If you start with a tattoo of size 10cm x 10cm and it shrinks to 5cm x 5cm then well done, your diet is going well. If however, it stretches out to 15cm x 20cm then lay off the ice-cream. |

(-) Why print this as a code rather than as the information itself? We do know how to OCR type, or at least certain kinds of type, and it's not *that* much information! |
|
| |
The idea was that you wave your phone around in the supermarket to find something you can eat, or do the math while you eat and remember the totals for you. QR codes have plenty of redundancy so they work without having to carefully scan every item - just point roughly and you'd hear 'yes' or 'no'. OCR would be way too picky. |
|
| |
All these packaged food items already have a UPC on them, why do they need a QR code? |
|
| |
Maybe your camera could just track the light reflecting off the grease of that Big Mac and eyeball the fat content from there. |
|

SC, true enough. Even found a place online you can look them up [link]. |
|
| |
A UPC probably wouldn't be sufficient as its more a "something like this indicator" and doesn't go down to the detail of e.g. a production line changing so that nut residue is a possibility. |

I'm guessing its going to be a while before there is a machine readable "this is exactly what you are buying". |
