In retail, a GTIN can call up the point-of-sale (price and retail category information. Take, for example, a lemon soda. The brand owner assigns and marks the soda with a GTIN. The brand owner then provides the GTIN and required attributes/info to the trading partner about the soda. The trading partner then adds pricing information to the database. When you select the soda off the shelf and bring it to the cashier, the item is scanned and the system can access certain information in the retailer’s database, such as the price. Then the available units can be updated once the soda is subtracted from inventory.
