I am thinking of a label system on cheese and egg found in supermarkets whereby you can use your phone camera to scan a bar code on those products. It would take you to a live supervision camera system via a standard app whereby you can navigate through the places where the chickens or cows breed, hatch, and give milk.
Via the QR code that could be found on the product, the seller, via agreement with the producers, can be brought to guarantee the cow can be followed, to check up on their health and happiness, and is not killed for meat, or actually not killed at all, not even in old age.
This would allow the direct consumer to envision whether a cow would care to give milk without breeding, or give excess milk, without suffering, and so on, first hand.
My question is: has this system been implemented anywhere?
