Every biker, yakuza, and anyone Gen X or younger has one, so why shouldn't food?
Yes, coming (maybe) to a store near yo may be laser-tattooed produce! The USDA is trying out some new technology to get us beyond the annoying sticky food labels we all have to contend with.
This solution would seem to not hold back in showing the industrial scale and standardization of food production, which is probably a good thing for consumers. My only worry is soon fruit and veg will start getting tricked out beyond recognition, a la Kanye at the VMAs.
