Abstract: A method for operating a computer system to provide information about a product to a customer is disclosed. The method includes receiving a login request identifying a specific business establishment and the customer from a customer device that is remote from the data processing system, and initiating a session for the customer between the computer and the customer device. When the computer receives a product code identifying a product in the business establishment that originates at a producer of the product, the computer sends information to the customer about the product, the information being verified by an organization independent of the producer of the product and the business establishment. The login request can be generated by the customer device interacting with a display at the business establishment, the display identifying the business establishment and optionally a location within the business establishment at which the customer is located.
