ELECTRONIC RECEIPT MANAGEMENT SYSTEM

摘要

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.

1. A distributed computer system configured to synchronize electronic records between a central computing entity and local computing entities, comprising:
a central server configured to assign a global user ID to a user and store, in association with the global user ID, a first local user ID assigned to the user by a first local server and a second local user ID assigned to the user by a second local server; a computing device of the user configured to generate one or more code symbols representing at least one of the global user ID, the first local user ID, and the second local user ID, and display the one or more code symbols on a display unit thereof; a first point-of-sale terminal associated with the first local server, configured to scan the one or more code symbols displayed on the computing device and code symbols of merchandise being purchased, and generate first transaction information including at least one of the global user ID, the first local user ID, and the second local user ID represented by the one or more scanned code symbols, wherein the first local server is configured to receive the first transaction information from the first point-of-sale terminal and transmit the first transaction information to the central server, and when the first transaction information includes the first local user ID, update a first point total of the user based on the first transaction information and transmit the updated first point total to the computing device of the user for display thereat; and a second point-of-sale terminal associated with the second local server, configured to scan the one or more code symbols displayed on the computing device and code symbols of merchandise being purchased, and generate second transaction information including at least one of the global user ID, the first local user ID, and the second local user ID represented by the one or more scanned code symbols, wherein the second local server is configured to receive the second transaction information from the second point-of-sale terminal and transmit the second transaction information to the central server, and when the second transaction information includes the second local user ID, update a second point total of the user based on the second transaction information and transmit the updated second point total to the computing device of the user for display thereat, wherein the central server receives the first transaction information from the first local server and the second transaction information from the second local server, and stores the received first and second transaction information in association with the global user ID.
