The benefits of bar codes

Bar code as a timely, accurate, reliable and economical means of data input has been adopted by logistics information system. It has been widely used in industrialized countries and has become a universal "identity card" unique to commodities.

Because of the use of bar codes, consumers have a sense of security from the psychological quality of goods, bar codes can also play an important role in the identification of shoddy products, anti-counterfeiting and anti-counterfeiting. Because bar code technology is advanced, applicable, easy to grasp and quick effect, it plays an advantage in information (data) collection. No matter in the process of warehousing, warehousing, shelving or customer settlement, it is necessary to face the problem of how to input the information of a huge amount of data (whether it is a whole package or a single retail after unpacking) into the computer. If on the packaging of a single commodity, printed bar code symbol, using bar code reader, can be high-speed, accurate, timely grasp the commodity variety (item number), quantity, unit price, manufacturer, date of delivery and other information. This not only improves efficiency, but also attracts more customers, reducing or eliminating the queuing phenomenon when customers settle accounts and pay after purchase. Bar code technology in China will be the main automatic identification technology, widely used in industrial automation control and all kinds of management information systems, and will penetrate into the field of multi-technology and high-tech products.

Bar code technology is used in logistics information system to complete the information collection and input of the computer. This will greatly improve the usefulness of many computer management systems. The application and promotion of bar code first comes from the modernization of commodity management, that is, the application of POS system. For example, there are about 220,000 kinds of commodities in American supermarkets, about 10,000 kinds of new commodities enter the market every year, and 10,000 kinds of old commodities are removed, with the proportion of new and old being up to 50%. Such a heavy workload is difficult to cope with without bar codes and POS system application. Today, Japan is at the forefront of the world in the application of POS system. At present, there are 48,000 manufacturers in Japan and about 100 million items of goods have adopted EAN code identification. A considerable number of merchants use the POS system entirely. The POS system is not limited to groceries, but also has been established in some specialized stores (such as medicine, cosmetics, tobacco and alcohol, etc.). At present, not only POS system has been widely used, but also market data exchange centers have been established in many countries to communicate information among production, supply and marketing, and trade data exchange organizations have been established to collect and summarize sales information of various stores and commodities and timely feed back to manufacturers. In this way, manufacturers can timely and accurately understand the sale, purchase and price of goods, can analyze the psychology of consumers, predict the market timely organization of supplies. Retailers can adjust the sales plan and purchase situation according to the situation.
