Advantages and application scope of bar code technology

bar code is a group of bar and empty symbols arranged according to certain coding rules to represent information composed of certain characters, numbers and symbols. Bar code system is an automatic recognition system composed of bar code symbol design, production, scanning and reading

Advantages of bar code technology:

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

a, fast input speed: compared with keyboard input, the speed of barcode input is 5 times that of keyboard input, and it can realize "real-time data input"

b, high reliability: the error rate of keyboard input data is 1 in 300, the error rate of using optical character recognition construction elevator safety rules gb10055 ⑴ 996 technology is 1 in 10000, and the error rate of using bar code technology is less than 1 in 1 million

c, large amount of information collected: using the traditional one-dimensional bar code can collect information of dozens of characters at a time, and the two-dimensional bar code can carry information of thousands of characters, and has a certain ability of automatic error correction

d, flexible and practical: bar code identification can be used alone as a means of identification, can also form a system with relevant identification equipment to realize automatic identification, and can also be connected with other control equipment to realize automatic management

in addition, bar code labels are easy to make, there are no special requirements for equipment and materials, identification equipment is easy to operate, does not need special training, and the equipment is relatively cheap

application scope of bar code technology:

commercial automation system: POS (point of sales) is a real-time system of commercial point of sale. The system takes bar code as the means and computer as the center to realize the management of purchase, sale and storage of the store, and quickly feed back the information of each link of purchase, sale and storage with good test accuracy, so as to provide information for business decision-making

application of bar code technology in warehouse management: three dimensional warehouse is an important part of modern industrial production. Using bar code technology, we can complete the guidance, positioning and grid operation of warehouse goods, improve the recognition speed, reduce human errors, and improve the level of warehouse management

bar code technology is also widely used in traffic management, financial document management, business document management, medical record management, blood bank blood management and various classification technologies. As a means of data identification and automatic data input, bar code technology has been widely used by people and penetrated into all fields of computer management. The development history of easily worn

bar code:

bar code technology has a history of more than 50 years. Initiated in the United States in the 1940s, these properties were widely used internationally in the 1970s and 1980s to obtain from raw materials. With the application of bar code technology abroad, China began to study it from the late 1970s to the early 1980s, and has improved the bar code management system in some industries, such as posts and telecommunications, banks, chain stores, libraries, transportation and major enterprises and institutions. In December, 1988, China established the "China article coding center" and formally applied to join the ean Association, an international coding organization, on April 19, 1991. In recent years, the bar code industry in China has developed rapidly. At present, the prefix codes used in commodities are "690", "691", "692" and "693". Bar code technology has been widely used in China
