At present, most goods sold in supermarkets use EAN bar codes. When selling, the scanner scans the EAN barcode, and the POS system finds the corresponding name, price and other information from the database, and makes statistics on the goods purchased by customers, which greatly speeds up the speed and accuracy of cashier. At the same time, various sales data can also be used as reference data for shopping malls and virtual businesses to purchase and supply.
Because of the timely and accurate statistics of sales information, merchants can accurately grasp the circulation information of various commodities in the course of operation, which can greatly reduce inventory and maximize the use of funds, thus improving the efficiency and competitiveness of merchants.
Second, the library. Bar codes are also widely used in the circulation of books in libraries. Bar codes are attached to books and library cards. When borrowing books, just scan the bar code on the library card, and then scan the bar code on the lent book, and the relevant information will be automatically recorded in the database.
When returning a book, as long as the barcode on the book is scanned, the system will check it according to the original record information, and if it expires, the book will be returned to the warehouse. Compared with the traditional way, this greatly improves the work efficiency.
Third, warehousing management and logistics tracking. For the occasion of the flow of goods, it is time-consuming and laborious to record the flow of goods by traditional manual recording method, with low accuracy. In some special occasions, manual recording is unrealistic.
Moreover, the application efficiency of these manually recorded data in the process of juice blending and query is quite low. The application of bar code technology can quickly and accurately record every item, and the collected data can be processed by computer system in real time, so that all kinds of statistical data can accurately and timely reflect the state of the item.
Fourth, quality tracking management. The O9000 quality assurance system emphasizes the traceability of quality management, that is, for products with quality problems, information such as production time and operators should be traceable.
In the past, it was difficult to record this information. Even though some factories (such as some home appliance manufacturers) used to use the form of processing sheets, with the accumulation of time, processing sheets became more and more, and some factories even used several houses to store these documents. The difficulty of finding a document from so many documents can be imagined!
If the bar code technology is adopted, the data of producers and products are recorded by scanning the bar code in the main link of the production process, and processed and stored by the computer system. If there is a problem with the product quality, the computer system can be used to quickly find out the data of the product in the production process, which provides a basis for the factory to find the cause of the accident and improve the quality of work.
Fifth, automatic data entry (two-dimensional bar code). The problem of inputting a large number of formatted documents is a very complicated matter, which wastes a lot of manpower and is difficult to guarantee the correct rate. With two-dimensional code technology, thousands of letters or Chinese characters can be put into a two-dimensional code the size of a business card, and these contents can be correctly input in a few seconds with a special scanner.
At present, computers and printers, as essential office supplies, have become quite popular. Some software can be developed to print the contents of formatted reports in two-dimensional bar codes at the same time. Scan the QR code of the place where these report contents need to be entered, and the report contents will be automatically entered. At the same time, the data can be encrypted to ensure the authenticity of the report data.
Bar code technology has been widely used in China's post and telecommunications system, library and information, production process control, medical and health care, transportation and other fields, especially with the continuous improvement of commercial informatization, bar code technology has gradually become popular, thus promoting the development of commercial pos systems.

Development of bar code technology:
In the mid-1980s, some institutions of higher learning, scientific research departments and some export enterprises in China gradually put the research and promotion of barcode technology on the agenda. Some industries, such as libraries, posts and telecommunications, materials management departments and foreign trade departments, have also begun to use barcode technology.
On April 9th, 199 1, China article coding center officially joined ean international, and the prefix code assigned to China by ean international was "690,691692". Many enterprises have obtained the right to use bar codes, which has enabled a large number of goods from China to enter the international market and brought considerable economic benefits to enterprises.
Bar code technology is widely used in commerce, postal service, book management, warehousing, industrial production process control, transportation and other fields. It is produced and developed in computer application, and has the advantages of fast input speed, high precision, low cost and strong reliability.
