ELECTRONIC RECEIPT MANAGEMENT SYSTEM THAT COORDINATES MANAGEMENT OF ELECTRONIC RECORDS IN A SECURE MANNER

摘要

A distributed computer system includes a central server, a computing device of a user, and a point-of-sale terminal. The central server is configured to assign a user ID to a user, and store payment information of the user in association with the user ID. The computing device is configured to generate and display a code symbol representing the user ID. The point-of-sale terminal is configured to scan the displayed code symbol and code symbols of merchandise being purchased, and generate first transaction information including the user ID and excluding the payment information and second transaction information about the purchased merchandise. A local server transfers the first and second transaction information from the point-of-sale terminal to the central server. The central server is configured to transmit the payment information to a payment processor to process payment for the merchandise being purchased, and payment confirmation to the local server.
