Wow, this is just amazing, being able to boycott foods and products based on the barcode and a barcode reader app, assuming one's phone is a higher end product.
Talk about a consumer game changer, this could be it. Imagine being in line and the person ahead of you is scanning all the product they put into their grocery cart, and suddenly they start tossing out one in five products while stating under their breath the reason why.
Sure that person could have barcode scanned the product when it was on the shelf, but the drama of doing it while in the grocery line could be intense.
