Method and apparatus for automated inventory tracking and authentication using device identity-containing information associated with at least one device that is part of an inventory. The method includes accepting initial device identity-containing information from an inventory origination point to a first sales distribution point and accepting additional device identity-containing inventory from each instance of a new and successive sales distribution point as inventory moves through a supply chain. This information is stored and then later compared to a device ID of the at least one device. An authentication action is performed upon the at least one device based upon said accepted initial and additional information. The device identity-containing information includes MAC address information, device serial number information.
