Bar code is a set of bars and empty symbols arranged according to certain coding rules, which is used to represent information composed of certain characters, numbers and symbols.
Bar code system is an automatic identification system composed of bar code symbol design, production and scanning reading.
First of all, talk about the application advantages of barcode:
First, the bar code is reliable and accurate. It can be concluded that keyboard input has an error every 300 characters on average, while barcode input has an error every 15000 characters on average. If the check is put in place, the error rate is one in ten million.
Second, the data input speed of bar code is fast. Keyboard input, a typist who types 90 words per minute can input 12 characters or strings in 1.6 seconds, while using bar code, the same work takes only 0.3 seconds, which is five times faster.
Third, the economy is cheap. Compared with other automatic identification technologies, the popularization and application of bar code technology takes a long time and costs less.
Fourth, flexible and practical. As a means of identification, bar code symbols can be used alone, or can be combined with related equipment to form an identification system to realize automatic identification, and can also be linked with other control equipment to realize automatic management of the whole system. At the same time, when there is no automatic identification device, manual keyboard input can be realized.
Fifth, there is great freedom. The degree of freedom of the relative position between the identification device and the barcode label is much greater than OCR. Barcodes usually only express information in one dimension, but the information on the same bar code is exactly the same and continuous, so that even if the label part is defective, the correct information can still be input from the normal part.
Sixth, the equipment is simple. Bar code printers are similar to ordinary printers. After the scanner is set up, you can read. The collector program is specially developed for easy pulse bar code, with on-site training and simple use. Bar code symbol recognition equipment is simple in structure, easy to operate and does not need special training.
Seven, easy to make. Printable, called "printable computer language". Bar code labels are simple to make and have no special requirements on printing technology, equipment and materials.
Advantages of barcode in various fields:
First, manufacturers: improve the competitiveness of goods in the international and domestic markets; It is convenient to collect sales information, understand consumption trends and effectively make production, sales and procurement plans; Improve the efficiency of inventory management. Through the collection and analysis of commodity sales information, it is convenient for product pricing.
Second, wholesalers: quickly and accurately handle orders and shipments; Accurate and meticulous inventory management to prevent the backlog of funds; Improve the quality of service to the retail industry and enhance competitiveness.
Third, retailers: collect commodity information, master best-selling commodities, and increase profits; Checkout is faster and more accurate. Promote the change of commodity prices; Save manpower and prevent staff from cheating; Get effective management of inventory, order, business and analysis.
4. Retailer employees: checkout is fast and accurate; Improve work interest, not easy to fatigue, and can improve the quality of service to customers.
Fifth, it is good for consumers: get fast and high-quality service; Because the calculation error is eliminated when checking out, customers can shop with peace of mind; Because bar code scanning stores can provide customers with more and better choices of goods, consumers can get a better shopping environment.
