Over the past few years, through the vigorous publicity, promotion and practice of China Article Numbering Center and sub-centers across the country, system integrators and other relevant parties, the application of barcode technology has been recognized and accepted by more and more people, especially barcode technology. The application in commodity circulation management has achieved very gratifying results. The bar code penetration rate of food, beverage, daily chemical products and other commodities is increasing day by day. 

Because of this, the application of barcode technology in commodity circulation management has been promoted, and more and more shopping malls, supermarkets, chain stores, specialty stores, etc. are partially or fully using barcodes to manage commodities. Some large shopping malls that use barcode management in an all-round way (such as Shanghai's Meimei Department Store, Times Square and other commercial buildings have realized full barcode management as soon as they opened) and supermarkets have appeared in Shanghai and other big cities, becoming the first choice for the application of barcode technology in commodity circulation management. model. the

Looking at the large shopping malls or specialty stores that use barcode management in an all-round way, it is not difficult to find that most of these commercial enterprises are Sino-foreign joint ventures or foreign-funded enterprises. This tells us that the awareness of the application of barcode technology in domestic commercial enterprises is far behind developed countries and regions, which is one of the reasons why our enterprise management level lags behind developed countries and regions. the

The benefits of applying barcode technology in commodity circulation management are obvious. It is not only convenient for sales, but also can avoid economic loss and management confusion caused by human errors, and can greatly improve work efficiency and management level. the

The promotion and application of barcode technology in my country has been highly valued by the relevant departments of the Chinese government, especially the application in commodity circulation management will become the most widely used field of barcode in our country. Therefore, all aspects attach great importance to the application of barcode technology in this field. There is no doubt about the comprehensive promotion of the application of barcode technology in commodity circulation management. Because it is currently the most advanced management method for commodity circulation management in the world. In order to make our country's business in line with international standards, we must vigorously promote and popularize the application of bar code technology in our country's commodity circulation management.

1. Basic work of barcode application

No matter in which field bar code technology is used, computer management must be realized first, and then the application of bar code technology can be discussed. , retail stores, etc. to achieve computer management. At present, the relevant departments of the Chinese government are vigorously promoting commercial automation throughout the country, that is to say, first of all, computer management must be realized in large and medium-sized shopping malls, supermarkets, chain stores, etc., which has laid a good foundation for the realization of barcode management and created favorable conditions. It is only one step away to implement bar code management in the shopping malls that have realized computer management, but it can receive unexpected results. the

Shopping malls that have realized computer management, including supermarkets and chain stores, must implement "single product" management in order to realize barcode management. For each commodity, according to its attributes and characteristics, according to certain rules, a "background code" must be compiled, which is the basic work necessary for computer management. In the "background code", it usually includes commodity categories, medium categories, small categories, suppliers, cabinet groups, materials, sizes, colors, brands, etc., relying on the computer to carry out statistics and analysis work according to the "background code" . As long as the "front code" used for sales and inventory is replaced with a barcode, and the barcode reading device is used, the barcode management of the product can be realized. It must be pointed out that "foreground code" and "background code" should not be confused. "Background codes" are usually over 20 characters long and therefore cannot be used as foreground opcodes. On the contrary, the front-end operation code cannot be too long, usually no more than 13 bits, which is not enough to fully represent the attributes and characteristics of the product. the

2. How to use the existing barcode on the product

Generally speaking, the barcodes on commodities imported from abroad are more in line with the norms and can be used directly. But the bar code on the domestic commodity due to various reasons. Phenomena such as non-compliant barcodes and repeated codes frequently occur, and the phenomenon that barcode readers cannot read due to printing reasons or improper color matching of barcodes often occurs. Therefore, before using the barcode to scan and sell goods, the barcode of a commodity must be carefully checked. The easiest way is to use a barcode reader to scan each product, remove repeated or unreadable barcodes, and re-attach the "in-store code" made by the user to this type of product. It seems that this is a very simple problem, but if the work is not done well, it will affect the accuracy of the data, and even cause some products to be unable to be sold using barcode scanning. the

In view of the numerous problems of barcodes on domestic commodities, we suggest that the China Article Numbering Center and local sub-centers, together with the State Bureau of Technical Supervision and local technical supervision bureaus, strengthen the inspection and supervision of barcodes on domestic commodities that do not meet the requirements , and make appropriate treatment to prevent the occurrence of similar phenomena, which is conducive to the promotion and application of barcode technology in commodity circulation management.

3. The use and production of in-store codes

In foreign shopping malls that use barcode management, there are two methods: one method is to use the "in-store code" made by the user regardless of whether there is a barcode on the product; the other method is to make full use of the original barcode on the product. The in-store code made by the user is only marked on the product without a bar code. In the shopping malls that have promoted the use of barcode management in China, there are no more than these two situations. The former approach is basically for mid-to-high-end shopping malls or specialty stores, while the latter approach is basically for all supermarkets and chain stores. Because the value of the goods is low and the sales volume of the goods is large, using all the codes in the store will increase the cost of the goods, which is not conducive to Merchandise sales in supermarkets and chain stores. Of course, the latter approach is also applicable to all shopping malls. The advantage of using all "in-store codes" is that the "in-store codes" can be compiled according to the user's own requirements for managing commodities, so as to meet the user's own management requirements. Another advantage is that the in-store code can be automatically generated by assembly line operation, which improves the efficiency of barcode production. 

The establishment of the "in-store code" should be carried out in accordance with the regulations of the China Article Numbering Center. Some users still don't know the regulations on the establishment of "in-store codes", which requires relevant departments to publicize and popularize them. To make "in-store codes", a dedicated barcode printer must be configured, preferably a barcode printer that can interface with a computer, and the required "in-store codes" can be produced through pre-programmed programs. Thereby reducing manual input errors and greatly improving work efficiency. If all users use "in-store codes", the in-store codes can be automatically generated through the application program in the POS system using the assembly line method, making barcode production more convenient, less labor-saving, and more efficient. 

4. Design of barcode POS system

There is no difference in principle between the design of POS systems using barcodes and the design of general POS systems. The difference between the two is that the former uses a barcode as the front code, and automatically reads the barcode through a barcode reader, avoiding errors when entering the code manually, and improving the input speed and work efficiency, especially for supermarkets. Prominent, can greatly reduce the waiting time of customers shopping settlement. 

For the selection of barcode readers, it is advisable to choose handheld barcode readers in large and medium-sized department stores, retail stores, specialty stores, etc., while in supermarkets it is advisable to choose laser flat-fitting barcode readers. 

The interface between barcode reader, cash register and computer is usually divided into two types: keyboard emulation input and serial port input. In application programming, as long as you pay attention to what interface is used, programming is not difficult. 

Therefore, commercial buildings, supermarkets, chain stores, specialty stores, retail stores, etc. that have realized computer management should lose no time in promoting the application of barcode management, and for commercial enterprises that have not realized computer management, they can consider using barcode management when designing computer management information. , In fact, using barcode management is not mysterious or difficult. the
