Abstract: The traditional paper shopping receipt has the disadvantages of wasting resources, endangering health and fading easily. In order to solve this problem, based on the Internet of things architecture, an electronic shopping receipt service system which includes the perception layer, network layer and application layer has been established. The system achieves the electronic shopping receipt. First, in the perception layer, a shopping receipt intelligent hardware and its driver have been developed. The shopping receipt intelligent hardware uses STM32 as the main control chip. A shopping receipt hardware driver has been developed through adding the relevant text description files, user interface plug-ins and rendering plug-ins into the framework of the general printer driver. After the installation of the driver of the cash register, the shopping receipt intelligent hardware will be able to collect shopping receipt information and transmit it to the network layer. Second, the network layer provides data transmission, processing, storage, equipment management, business management, membership management and other services. Third, We Chat applications on the application layer provide customers with shopping receipt real-time push, the history of shopping receipt inquiries and integral query services. Offline retail business applications on the application layer can provide visual data management, accurate recommendation of users, regional best-selling products and other services. The designed electronic shopping receipt service system meets the goal of building a resource-saving and environment-friendly society, and can realize the intelligent application of electronic shopping receipt and promote the transformation and updating of off-line retail industry.
