Convenience is one of the biggest benefits of the EPC. It can also help merchants keep popular products from running out by tracking inventory and ordering re-supplies more quickly. Some shopping carts are being equipped with readers that will communicate with tags embedded on store shelves. When the consumer walks by, a small screen on the cart will display promotions, recipes, and other information connected with those products.
Safety is another benefit. For example, tagging prescription drug bottles with the EPC at the manufacturer can help pharmacies assure that the drugs they are providing to consumers are real, not counterfeit and that the prescription drugs being dispensed are those that the doctor prescribed. Stores can use RFID to locate and remove perishable items that are past their prime or recalled items from their shelves. RFID can also help protect the public health by enabling companies to track the source of an item – like a bag of spinach or beef from a cow, in case of disease.
