Retail commodity traceability-based electronic two-dimensional code scale

Abstract

The invention discloses a retail commodity traceability-based electronic two-dimensional code scale. The two-dimensional code scale comprises an information loading module, a traceability system platform database, a touch screen, a touch action processing module, a weighing sensor, a metering module, a commodity information display module, an encoding module and a two-dimensional code printer. According to the retail commodity traceability-based electronic two-dimensional code scale of the invention, a touch screen input mode is adopted to replace a keyboard input form, so that complexity of bonding labels on a keyboard can be avoided; and a two-dimensional code is adopted to replace a conventional one-dimensional bar code, so that more information can be carried, and requirements of modern supermarkets, for the management of a large number of commodities, can be satisfied.

Description

Technical field [0001] The invention relates to the technical field of electronic scales, in particular to an electronic two-dimensional code scale based on the traceability of retail commodities. Background technique [0002] At present, agricultural products supermarkets generally use electronic barcode scales and use sticker keyboards to identify products, and one-dimensional barcodes carry information about the products. Although the electronic bar code scale has the characteristics of low price, the operation of the electronic bar code scale requires manual production of product identification. One-dimensional bar code cannot carry a large amount of commodity information, and there is no back-end management platform to manage the sales of commodities. In addition, the electronic labels of commodities in modern supermarkets are mostly marked in the form of two-dimensional codes. Modern payment methods (such as WeChat and Alipay) use the form of reading two-dimensional codes. ...

Problems solved by technology

Although the electronic barcode scale has the characteristics of cheap price, the operation of the electronic barcode scale requires manual product identification, and the one-dimensional barcode cannot carry a large amount of commodity information, and there is no background management platform to manage the sales of commodities

In addition, the electronic tags of commodities in modern supermarkets are mostly marked in the form of two-dimensional codes, and modern payment methods (such as WeChat and Alipay) are in the form of reading two-dimensional codes. Two-dimensional codes carry more information, which can meet the needs of modern supermarkets. requirements, while traditional supermarket electronic barcode scales generally use one-dimensional barcodes, which carry less information and cannot meet the development requirements of modern supermarkets.

[0003] The key to the traceability process of retail goods is the traceability of the goods in the hands of consumers. When the products produced by enterprises or farmers are disassembled and sold in shopping malls or farmers’ markets, the traceability information on the large packaging cannot be provided to consumers when the products are disassembled and sold, resulting in Consumers cannot directly scan codes to learn about traceability information through mobile phones
