The application of bar code technology in commodity circulation management has obviously become a field where bar codes are widely used in our country. Therefore, all aspects attach great importance to the application of barcode technology in this field. It is beyond doubt to fully promote the application of barcode technology in commodity circulation management. At present, bar code technology is an advanced management method for managing commodity circulation in the world. To make our business in line with international standards, we must vigorously promote and popularize the application of barcode technology in commodity circulation management.

1. Barcode application prerequisites

The implementation of commercial automation is a good foundation for the application of barcode technology. No matter in which field barcode technology is used, computer management must be realized first, and then the application of barcode technology can be discussed. The use of barcode technology in commodity circulation management is no exception. , retail stores, etc. to achieve computer management. This has laid a good foundation for 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.

Shopping malls that have realized computer management, including supermarkets and chain stores, etc., must achieve "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.

2. Bar code technology and POS system

What is a POS system?

POS (Point of Sale) system refers to a network system composed of electronic cash registers and computer connections. Through this system, shopping malls can collect, process, organize, analyze, transmit and feed back the information of the entire commercial activity, modernizing the marketing management of shopping malls. . The POS machine is the core part of the system. Generally speaking, the POS machine is divided into three categories from the perspective of system application:

(1) A type of machine, namely ECR. It can only be used to enter the cash amount and balance the actual cash received, but does not have the networking function, cannot provide product information to the information center in time, and the number of managed products is very limited; (2) Class II machines, including ECR and PROPOS . It realizes pricing by entering the commodity code PLU, and can summarize the amount of large categories, and also has the function of networking. But the memory capacity is limited and the processing speed is very slow; (3) Three types of machines, namely PROPOS and PCBASE. This machine can apply bar code technology, has networking function, complete functions and excellent performance, it is a new generation of POS machine. With the improvement of the modern management level of shopping malls, it is a trend to adopt the second type, especially the third type machines. And these two types of machines must be based on commodity barcodes to achieve.

Application of bar code technology in POS

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 the bar code as the front code, and automatically reads the bar code through the bar code reader, avoids the error when entering the front code manually, and improves the input speed and work efficiency, especially for the supermarket, its benefits are more prominent , Can greatly reduce the waiting time for customers to shop and settle.

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 barcode readers.

The interface between barcode reader, cash register and computer is usually divided into two types: keyboard simulation 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 seize the opportunity to promote 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.
