1. The concept of barcode

A barcode is a mark composed of a set of regularly arranged bars, spaces, and corresponding characters. "Bar" refers to the part with low reflectivity to light, and "space" refers to the part with high reflectivity to light. The data composed of these bars and spaces expresses certain information, and can be read by specific equipment and converted into Computer compatible binary and decimal information. Usually, for each item, its code is unique. For ordinary 1D barcodes, the corresponding relationship between barcodes and product information must be established through the database. Applications manipulate and process data. Therefore, the ordinary 1D barcode is only used as identification information during use, and its meaning is realized by extracting the corresponding information from the database of the computer system.

2. Advantages of barcode technology

In the vernacular, the biggest advantage of barcode technology is its benefits.

Barcode is by far the most economical and practical automatic identification technology. Barcode technology has the following advantages:

A. Fast input speed: Compared with keyboard input, barcode input is 5 times faster than keyboard input and enables "instant data entry".

B. High reliability: The error rate of keyboard input data is 1 in 300, the error rate of using optical character recognition technology is 1 in 10,000, and the error rate of using barcode technology is less than 1 in 1 million.

C. Large amount of collected information: The traditional 1D barcode can collect information of dozens of characters at a time, and the 2D barcode can carry information of thousands of characters, and has a certain ability of automatic error correction.

D. Flexible and practical: barcode identification can be used alone as a means of identification, or can be combined with related identification equipment to form a system for automatic identification, and can also be connected with other control equipment for automatic management.

In addition, barcode labels are easy to make, there are no special requirements for equipment and materials, the identification equipment is easy to operate, no special training is required, and the equipment is relatively cheap.

3. Application fields of barcode technology

Bar code technology is widely used in many fields such as warehousing, post and telecommunications, transportation, commercial inventory, book management, production process control, etc. The most widely used and most familiar barcode technology is the POS (Point Of Sale) system in the field of general commodity circulation and sales, also known as a sales terminal or scanning system. POS systems are widely used in North America, European countries and Japan, and the penetration rate has reached over 95%.

Asian countries started late in the development and application of barcode technology. Hong Kong established the Article Numbering Association in November 1989. In 1988, the State Council approved the establishment of the "China Article Numbering Association" under the unified leadership of the State Bureau of Technical Supervision. In 1990, the State Bureau of Technical Supervision issued the "Notice on the Use of Barcode Marks for Exported Commodities".

Barcode technology is a high-tech in the field of electronics and information science. It studies how to represent the data required by the computer with a set of barcodes, and how to convert the information represented by the barcode into computer-readable data, including research on coding rules and standards, symbols Technology, automatic reading technology, printing technology, application system design technology and other five parts. After years of research and application practice, barcode technology has developed into a relatively mature practical technology. It has the advantages of simple operation, fast information collection speed, large amount of collected information, high reliability, simple equipment structure, and low cost, so it has broad development prospects.

Business is one of the earliest fields to apply bar code technology. In the process of commercial automation management, popularizing commodity barcodes is the key. Manufacturers can be the first to obtain information from the barcode information system and benefit first. Once manufacturers realize the importance of barcodes and actively adopt barcodes on their products, the users of barcode systems will increase dramatically, and the popularity rate of commodity barcodes will be greatly improved.

The purpose of promoting barcodes on commodities is first of all to automate store management. In other words, it is necessary to realize the digitization of commodity management and the automation of external operations. In this process, the establishment of the POS system is very important.

POS system, also known as point-of-sale management system, uses a cash register as a terminal to connect with the main computer, and uses photoelectric reading equipment to input information for the computer. When a commodity with a barcode symbol is scanned by the checkout counter, the information represented by the commodity barcode is entered into the computer, and the computer queries the name and price of the commodity from the database file, and after data processing, the receipt is printed out.

The establishment of the POS system can enable merchants to understand the business situation in a timely manner, reduce inventory, reduce costs, and improve efficiency. Manufacturers can obtain commodity and market information in time from the POS system, adjust production structure in time, and improve product competitiveness. At the same time, the POS system provides customers with more satisfactory services.

The purpose of collecting commodity information is to use information and realize resource sharing through information exchange, thereby improving the utilization rate of information and serving scientific decision-making. Without information exchange, the bar code system cannot exert its due benefits. As the carrier of commodity information, barcode not only establishes the link between manufacturers, wholesalers and retailers, but more importantly, it provides a common "language" for electronic information exchange.

Many people do not understand the true connotation of the commodity barcode system, and mistakenly think that the commodity barcode is just the identification code of the commodity. In fact, the real significance of promoting commodity barcodes lies in the electronic data interchange (EDI) of commercial information, so as to realize paperless trade. In this way, people can obtain the required business information in a timely and accurate manner through the electronic information exchange system, and improve production and operation efficiency.

The following are several other typical applications:

1) Warehouse management barcode system

Barcode warehouse management is a traditional field where barcode technology is widely used and relatively mature. It is not only suitable for commercial commodity inventory management, but also for factory product and raw material inventory management. Only the realization of electronic warehouse management (inventory) can make full use of product and raw material information resources. Warehouse management is dynamic. Through the establishment of an electronic warehouse management (inventory) system, managers can keep abreast of the current quantity and dynamic changes of each product or raw material on the shelf and in the warehouse, and quantitatively analyze the inventory of various products. Or raw material inventory, sales, production and other information. Managers use it to purchase or reduce purchases in a timely manner, adjust production, maintain optimal inventory, improve inventory structure, accelerate capital turnover, realize overall control and management of products and raw materials, and update management methods. Features of electronic bar code warehouse management (inventory): real-time data. The data acquisition system adopts barcode automatic identification technology as the data input means. While performing each product or raw material operation (such as arrival inventory, storage, inventory), the system automatically processes the relevant data and prepares for the next operation ( Such as financial management, outbound) data preparation, non-stop operation.

2) Application of barcode in industry

Ford Motor Company of the United States imports 1.5 million cars to Europe every year, each with a barcode indicating its model, specification and assembly plant, replacing the manual record of the factory number as many as 11 times during the delivery and resale of vehicles in the past tedious work. Ford's Saorlouis factory in Belgium also engraved the barcode on the metal parts at the bottom of the car body; through a scanning device on the assembly line, the whole process of the vehicle from the assembly to the delivery can be tracked. As a competitor of Ford Motor Company, General Motors, it has used bar codes to distinguish the main components of power machines, such as valves and carburetors. These parts can form 15.5 million different models of power machines, but GM only needs 438 of them. By inputting barcodes into the computer, those useless model structures can be avoided. Many countries have adopted barcode technology on automatic production lines to improve the efficiency and accuracy of the production process.

3) Fixed asset management and file management

Fixed asset management and file management With the need to reduce costs and streamline organizations and the increasing number of fixed assets, the application of barcode technology to manage fixed assets will be very effective. Use barcodes to classify and code fixed assets; use barcode data collectors to carry out asset inventory, and establish a fixed asset database through asset inventory; use barcode data collectors to control the purchase and use of fixed assets and database maintenance and management in real time. ; Use barcode data collectors for regular inventory of fixed assets.

4) Attendance and guard management

(1) Gatekeeper management: each legal entrant holds a barcode card, and when entering, swipe the card or swipe the card and add the password in the card slot scanner. If it is correct, the host computer in the system will control the electronic lock to open through the relay, otherwise, the door will not be unlocked. open. (2) Attendance management: Using barcode technology to manage the personnel attendance of enterprises and institutions can overcome various disadvantages of mechanical clocking, and is an important symbol of modern management of an enterprise.

5) Post and telecommunications management

In post and telecommunications business management, there are a large number of mail processing, such as registered mail, express mail and so on. In order to clarify responsibilities and facilitate inquiries, during the handover process, the staff must log in the list as a voucher for mutual handover. In the past, the manual method of registration list has been used, which is heavy workload, low efficiency, and easy to cause human error. Applying barcode technology to post and telecommunications business management has fundamentally changed the traditional manual login method, freed the staff from the busy and tense work, avoided human errors, greatly improved work efficiency, and automated the registration operation Prerequisites are provided. The barcode mail management system includes the following contents: Barcode and barcode registered mail Since registered mail is circulated throughout the country, it is required that the bar code registered mail used in mail has a unified standard throughout the country.

6) Barcode customs declaration management

The use of barcodes to manage import customs declarations can effectively solve the problem of missing orders in the management of customs declarations.

7) Barcode library management system

As we all know, library management can be divided into categories, and its classification uses codes, so that each book has a call number, and the call number is printed as a barcode label and pasted on the book. With the use of the computer system, when books are flowing, just scan the barcode of the call number, which saves the process of typing in a long string of book numbers, and the error rate is extremely low.

8) Barcode shopping mall management system

It mainly uses the commodity bar code and the in-store code to electronically manage the purchase, sales and inventory of the shopping malls.

9) Barcode blood staff, blood bank management system

The application of barcodes in the management of blood donors and blood banks is mainly the tracking management of blood donors and the management of blood banks.

Of course, barcodes have penetrated into all areas of our production and life, and there are various other applications that cannot be listed one by one. In fact, as long as you need to quickly identify data and have space to engrave or paste barcodes, you can use barcode technology for rapid and automatic identification!
