San Diego-based Harney Sushi is printing quick response, or QR, codes on rice paper wafers using edible, water-based ink. The sushi rolls are wrapped in the wafers, making it easy for smart phone-carrying diners to scan in the codes and learn more about the fish they’re consuming.
The QR codes direct diners to the National Oceanic and Atmospheric Administration’s FishWatch website, a clearinghouse for seafood news and sustainability facts.
“Sustainability is based on a simple principle – meeting today’s needs without compromising the ability of future generations to meet their needs, for example, using a resource but leaving some for the future,” the NOAA says on its FishWatch website.
