How is "one item, one code" traceability achieved?

The implementation of "one thing, one code" traceability is a systematic process based on advanced information technology and Internet of Things technology. The following is a detailed explanation of its implementation steps:
1、 Encoding and coding
The first step of the "one item, one code" system is to assign a unique QR code to each product. This QR code not only represents the unique identity of this product, but also contains its key information. Enterprises generate unique QR codes for each product through coding management modules and associate the QR codes with product information. Next, after the products are packaged in smaller sizes on the production line, the traceability source code is exported from the coding software module in the one item one code traceability management system, and the coding work for smaller packaging is completed by hardware devices such as printers and labeling machines.
2、 Data collection
Data collection is the core component of the "one object, one code" system. In the production, circulation, sales and other stages of the product, the system collects and uploads relevant data to the traceability system by scanning the QR code. These data include but are not limited to production date, production location, raw material source, quality inspection records, logistics trajectory, etc. The data collection module is responsible for capturing and recording this information in real-time at various stages, ensuring the accuracy and completeness of the data.
3、 Data upload and association
The collected data will be uploaded to the enterprise database or external regulatory platform system. In this process, the system establishes packaging associations at all levels through software, linking packaging information at different levels with product information. This association enables consumers or regulatory agencies to trace back to the source of product production and understand the entire production process by scanning the QR code on the product.
4、 Traceability inquiry
Consumers, businesses, regulatory agencies, and other parties can query product information through the user interface module. Consumers only need to scan the QR code on the product to obtain information such as production date, place of production, source of raw materials, shelf life, etc. Enterprises can use visual data analysis reports to understand the production, circulation, sales, and other situations of goods, in order to better formulate production and sales plans. Meanwhile, regulatory agencies can also supervise the circulation of goods through the system to ensure their safety and compliance.
