What a great idea! A barcode on produce that measures freshness. No more guessing.
Each bar code uses a special ink that recedes in correlation with passing time and a percentage graph indicating the remaining life of the veggie at hand. So is it time to cook it or compost it? This cabbage looks like it’s on its way out!




Why not just a best before date…….most veggies you can tell wether you have to take them home and eat me now, some just look fresh enough to last a few days firm and tight.
