What is the role of the POS system?
The basic components of the POS (Point of Sale) system that play its management functions are commodity barcodes, POS cashier systems, and back-end computers. Currently, there are international EAN barcodes for use in Europe, which are commonly used in the United States and Canada for UPS barcodes. EAN barcodes are compatible with UPS barcodes and are classified by the International Code Coding Committee (EAN) and the United States Uniform Code Council (UCC). Member States that join a bar code organization can obtain an international uniform number prefix assigned by the organization. The China Article Numbering Center officially joined the International Article Numbering Association in 1991. The prefix code assigned to China by the Association is 690. The international commodity code headed by 690 is the Chinese commodity code, which is the EAN code. The standard EAN code consists of 13 digits called EAN-13 code, which consists of 3 country codes, 4 vendor codes, 5 commodity codes and 1 check code. The manufacturer code is assigned by the China Article Numbering Center, and the commodity code is programmed by the manufacturer. The checkmark is to prevent misreading. Recently, the International Article Numbering Association has assigned a prefix number "691" to the China Article Numbering Center. Commodity barcode is a high-speed and accurate data input technology developed to adapt to the development of computers. The commodity barcode is applied to the POS system. It uses the cash register as the terminal to connect with the host, and enters the commodity information by means of the photoelectric reading device. When the information represented by the barcode symbol is recorded to the computer, the computer searches the database. The name, price, etc. of the product are processed, the billing list is printed out, and each sales situation is recorded. The POS system not only realizes the automatic management of goods import, sale and storage, but also provides the best quality service for customers, which greatly improves the management quality and management efficiency of the supermarket. 2. POS cash register system (2) Computer cash register + scanner. The system is more suitable for smaller supermarkets, and the computer cash register has the functions of cash register and access to the goods in the computer. Scanners, also known as commodity bar code readers, are an important part of POS cash registers. The principle of the scanner is to use light reflection to read the light source reflected by the barcode and then translate it into an identifiable number to confirm whether it is the commodity code of the file. At present, there are generally three types of scanners for POS cash registers: one is a light pen, one is a hand-held scanner, and the other is a fixed scanner. The advantages of the first two scanners are: first, the price is cheap, and second, it is more suitable for goods that are difficult to see in the bar code position of the product. The disadvantage is that the scanning induction is poor, and the scanning action often needs to be repeated several times before sensing. The latter scanner is exactly the opposite of the first two advantages and disadvantages. (2) Main operation and management functions of the POS operation system 1. POS system operation function 2. POS system management function 1. The use of POS system, a modern scientific management tool, will provide supermarkets with faster, more accurate and more useful information, and provide a reliable basis for decision-making. We say that the establishment of the independent position of the supermarket in the circulation market is also inseparable from the POS system. The supermarkets grasp the consumption trend and the creation of new consumer demand is also inseparable from the POS system. The supermarket is actively guiding the industrial production with the consumption future grasped by the POS system.

(1) Introduction to the basic components of the POS system
Product barcode
The merchandise barcode consists of a number of black and white stripes on the merchandise package, marked with a number pattern. The commodity barcode is a commodity identification mark, which is a code for the photoelectric reading device to input data to the computer, and the content thereof includes information such as the country of manufacture, the name of the product, and the product number of the product. Bar code is defined as: a group of different widths, different reflectivity, parallel adjacent bars and spaces, combined according to a predetermined numbering rule, used to represent a set of data symbols, this data can be numbers, letters or some Some symbols.
Supermarkets can only read commodity barcodes using the POS cashier system. Check out the cashier and record the sales of the goods. At present, there are two main types of P03 cash register systems:
(1) Electronic cash register + scanner - main controller + computer. The system is generally suitable for supermarkets with large scale and many cashier counters. The main controller can store the main file data of the goods, and transfer the product sales data to the background computer in batch mode, which can alleviate the workload of the background computer.
3. Background computer
The POS system must be able to operate normally, and the back-end computer must establish the main file of the product. After the scanner receives the product barcode information, it must go to the background computer to find the product master file to identify whether the product code is correct, then accept the product price, and record the sales amount of the product. It can be seen that the background computer is a commodity information base and a control center for the front-end POS cash register. Therefore, when the first time you enter the supermarket for sale, you must enter the basic information about the product into the back-end computer according to the prescribed format. At this time, the product can enter the sale. The power to establish the main product data in the commodity procurement personnel, when the computer personnel receive the instructions of the purchasing personnel, can only enter the main product information information into the background computer. For the supermarket chain company, the establishment of the main product data is carried out by the Headquarters Purchasing Department. For example, if the computer is connected to the Internet, the back-end computers of each supermarket store can be transmitted. If the network is not connected, the magnetic card can be sent to each store and then input to the back-end computer. File.
The American Retail Industry Association has conducted a survey of the retail industry using the POS system, which shows that 80% of retailers believe that "POS systems are the only direction for the retail industry." It can be seen that the modern retail industry is inseparable from the POS, and the operation and management of the supermarket is inseparable from the application of the POS system. This is because the operation function and management function of the POS system bring huge benefits to the supermarket.
The main functions of the POS system are as follows:
(1) When the supermarket performs the cashier settlement, the POS cashier automatically records the original data and other related materials of the merchandise sales, and according to the computer program design requirements, there is a period of guaranteed recording period.
(2) The POS cash register automatically stores and organizes the recorded sales data for the whole day, which can reflect each time point, time period and instant sales information as the basis for processing to the background computer.
(3) The small printer on the POS cash register can print out various cashier statements, reading accounts, clearing accounts, and time department accounts.
(4) The central computer at the headquarters of the supermarket chain company can use the communication networking system to deliver information such as management orders, commodity price changes, and goods distribution to each supermarket store.
(5) The central computer can also statistically analyze the business information of each store and generate the management information materials required by the headquarters departments as the basis for decision-making at the headquarters.
(6) The POS system can quickly and accurately complete the cashier's work at the front desk, while maintaining a complete record.
(1) The POS system can obtain the sales information of the goods accurately and quickly, and help to adjust the purchase and commodity structure in the commodity management, reduce the business losses, and seize the business opportunities;
(2) It can be used as a commodity price management as the most powerful basis for promoting sales and purchases;
(3) It can be managed as a target of consumption, as a targeted purchase and sale of goods;
(4) It can be managed as a business time to reasonably equip the sales staff and save labor costs;
(5) It greatly saves the time for the sales staff to prepare the statements, which is beneficial to the actual sales operations at the site.
(6) The POS system can conduct ABC analysis on commodities in different categories, and can also compare the analysis of supermarkets with the increase of last week, last month and the same period of the previous year according to the business data, and the operators can formulate the business plan for enterprise development accordingly. Wait.
2. The use of POS systems will greatly reduce the inventory of supermarkets and the ability to increase sales, greatly improving the turnover rate and gross profit margin of goods. Since the POS system can accurately grasp the types, quantities and prices of products that are put on the market, coupled with the cooperation of the product procurement and distribution system, the increase in the commodity turnover rate and gross profit margin, the reduction in the inventory of goods and the reduction in the price of goods become a matter of course. Things.
3. China's retail industry is experiencing a revolution. The retail industry is developing in a large-scale, chain-oriented and customer-oriented way. The traditional retail management method can no longer meet the needs of this development, as a kind of commercial automation. The role of modern management tools and the benefits they bring to supermarkets and other retail industries will be enormous.
