Whole process traceability of agricultural products? What is the workflow of the system?
The agricultural product traceability management system based on the QR code can realize the combination of the object code and the scanning code query. Most of the traceability query result interface fed back to the consumers is text and picture information, so as to better serve the agricultural products companies or farmers as well as consumers. provide services. So what is the workflow of the whole-process traceability system for agricultural products designed based on QR code technology? 1. Scanning QR codes, also known as 2D barcodes, is one of the popular coding methods in recent years. QR codes are easy to operate and use. With the characteristics of convenient information storage and rich data types, conventional two-dimensional codes are composed of white and black square symbols and their structure is relatively simple. When storing data, the two-dimensional code uses binary format to store various text symbol information, and both Chinese, English and numbers can be stored quickly and efficiently. When using the QR code, you need to scan the QR code with devices such as mobile phones and tablet computers. No matter which direction you scan, you can get the result information. 2. View the complete traceability information The dynamic information QR code is different from the conventional static information QR code. It can realize different codes for different batches of products. The advantages of the dynamic information QR code in the traceability system will be very obvious. The QR codes printed on the business card promotion color pages and display stands, etc., are all QR codes with fixed information. If the two-dimensional code is used to achieve anti-counterfeiting traceability, the two-dimensional code needs to be intelligent, which can distinguish each product of the enterprise and summarize it into an anti-counterfeiting traceability system, so that these products can be managed from this system. If the logistics and other information of the product change, the change information can be associated and updated in the system so that consumers can see the complete traceability information of the product. The consumer traceability query function is also one of the core functions of this system. This function is to feed back the product traceability information to consumers directly through the web interface. In order to ensure the safe, stable and efficient operation of the system, the whole process of product traceability and traceability is particularly important. The system compatibility test is particularly important to test whether the function of the system is completely normal and whether there is hidden compatibility when running on different operating systems and browsers.
