Use Your Phone to Check Your Food

There is so much information that we need to know about what we eat, and it often either can't fit on the label or the manufacturers don't bother giving it. And, while a box of twinkies might list the ingredients inside, you don't get much information on an organic head of lettuce. In Japan's Ibaraki Prefecture, the farmers are tagging their produce with bar codes that you scan with your cel phone camera, much like last year's Finnish Camera Phone. "The code links to a mobile website detailing origin, soil composition, organic fertilizer content percentage (as opposed to chemical), use of pesticides and herbicides and even the name of the farm it was grown on." Add a link to google maps and it could probably figure out the carbon footprint of its delivery. ::Corporate Knights
