It’s easy to scan a product in a shop with eg a smartphone and get a tonne of information about the damage it caused by being flown around the planet, how many calories it will attach to your waistline etc., etc.
Today’s invention extends that idea into a new dimension: profit.
Each product would be assessed by an online crowd of experts with inside knowledge of processing and manufacture in a number of industries. They would come up with an estimate of its cost to make and appear on the shelf.
This would then allow one’s phone to indicate the markup being asked by the store and provide consumers with visibility of a seller’s true pricing policy.
