Abstract

A distributed computer system includes a central server, a computing device of a user, and point-of-sale terminals. The central server is configured to assign a global user ID to a user and store, in association with the global user ID, local user IDs. The computing device is configured to generate and display a code symbol representing at least one user ID. A point-of-sale terminal is configured to scan the displayed code symbol and code symbols of merchandise being purchased, and generate transaction information. A local server is configured to transfer the transaction information from the point-of-sale terminal to the central server. When the transaction information includes a local user ID, a point total of the user is updated based on the transaction information and transmitted to the computing device. The central server stores the transaction information, which is received from the local server, in association with the global user ID.
