Patent attributes
In certain embodiments, a system includes a processing system and tangible computer-readable media accessible by the processing system. The media may store software and purchase order identifications. Each purchase order identification indicates a respective one of the purchase orders and is globally unique with respect to each other purchase order identification. The software when executed by the processing system is configured to perform operations, including accessing a request comprising a particular one of the purchase order identifications. The request had been generated at a client device that had decoded the particular purchase order identification from an optical scan of a code provided with packaging of one or more products of the respective purchase order indicated by the particular purchase order identification. The operations further include generating data for receipt by the client device. The data comprises information that facilitates returning at least one of the products.
