What is the function of the barcode of the product?

The main uses are as follows:

1.Representing product categories, such as the barcode on cigarettes, the 13-digit barcode on the same cigarette, are all the same. This barcode is called EAN-13 code, also known as commodity code, and you need to go to the relevant department to register before you can use it.

2.Represent product categories for easy management. This is usually seen more in supermarkets. Some products in the supermarket do not have the EAB-13 code mentioned in the above article, so the supermarket will paste the barcode defined by the supermarket according to different categories.

The above two practical aspects are the same, but the difference is that the first is to be registered, and the second is the internal norms formulated by the enterprise.

3.Represents a separate product. This is usually done as a serial number. For example, there is a barcode on the nameplate of household appliances, and this barcode is unique and only represents a product. It is used for the management of product production, inventory, quality assurance, etc.

4.Special industry management. For example, the postal service has a special code for management, which can be seen on the back of the envelope.

5.Security. Through the back-end database, each barcode has a unique corresponding data.

The scan data can be transferred to the computer to compare with the data in the database. The content of this barcode is usually generated randomly. Mainly used for lottery, train tickets, plane tickets, discount coupons, etc.

Many products in supermarkets are printed with parallel stripes of different widths and black on the outer packaging, which is the ID card of the goods. Each commodity has only one unique commodity barcode in the world, when identifying it.

Standard EditionItem barcode(ean 13 barcode) is composed of 13-digit waiter words, and the structure is as follows:

The first 3 digits are the prefix code (the prefix code assigned to China by the International Article Number Association and enabled is "690 693").

When the prefix code is "690" and "691", the 4th to 7th digits are the manufacturer**, the 8th to 12th digits are the product items**, and the 13th digit is the check code. When the current code is "692" and "693", the 4th to 8th digits are the manufacturer**, the 9th to 12th digits are the commodity items**, and the 13th digit is the check code.

Commodity barcode uses:

First, used to identify the type of goods: the goods plus the bar code, you can avoid human judgment, such as the purchase, sales, inventory, etc. can use the bar code to identify the goods, which can also speed up the work, more efficient.

Second, the manufacturer can pass the barcode.

Identifying goods**, such as cigarettes, according to the regulations, cigarettes cannot be transferred across regions.

3. The barcode can reflect product information, such as the origin of the product, the category of the product, and the product. The same.

Commodity barcodes can enable enterprises to improve business efficiency and productivity, and improve the management of the entire ** chain.

1) Benefits to manufacturers: conducive to product entry into the market; It is conducive to collecting commodity information, understanding consumer trends, and quickly feeding back consumer demand; Improve the efficiency of inventory management; Improve the efficiency of shipment and transportation, and reduce the cost of logistics operations; Quickly collected product information is used for analysis, making it easier to plan production and price products.

2) The benefits to wholesalers: fast and accurate processing of orders and shipments; Accurate and detailed inventory management to prevent backlog of funds; improve the quality of service to the retail sector; Accurately grasp the business situation, enhance competitiveness, and create higher profits.

3) Benefits to retailers: quickly grasp the sales information of goods, understand the best-selling products, and increase profit opportunities; Settlement is faster and more accurate, so that customers can shop with more confidence; Inventory, ordering, shipment, business analysis, etc. are effectively managed; Create a better shopping environment and provide better services to consumers.

The commodity barcode is generally composed of the prefix part, the manufacturer**, the product** and the check code. The prefix code in the commodity barcode is used to identify the country or region, and the right to assign the code is in the International Article Number Association, such as 00-09 on behalf of the United States and Canada. 45 49 for Japan.

690-695 represents Chinese mainland, 471 represents Taiwan, and 489 represents Hong Kong SAR.

Empowerment of Manufacturers** In the article coding organization of each country or region, China is empowered by the National Article Coding Center to manufacturers**. Commodities are used to identify the goods, and the right to assign codes is exercised by the product manufacturers themselves, and the manufacturers decide which Arabic numerals are used for the commodity barcodes in accordance with the prescribed conditions.

At the end of the product barcode, a 1-digit check code is used to verify the correctness of the 1st 12th digit ** from the left in the product barcode. Commodity barcode refers to a set of regularly arranged bars, blanks and their corresponding characters composed of logos, used to represent a certain commodity information symbols.

Commodity barcode is a set of bars and empty symbols arranged according to certain coding rules to represent information composed of certain characters, numbers and symbols. The barcode system is an automatic identification system composed of barcode symbol design, production, scanning and reading.

Advantages of barcode technology:

Barcodes are by far the most economical and practical type of 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 it can be achieved"Instant data entry".

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

c Large amount of information: the traditional one-dimensional barcode can collect dozens of characters of information at a time, and the two-dimensional barcode can carry thousands of characters of information, and has a certain automatic error correction ability.

d Flexible and practical: barcode identification can be used alone as a means of identification, and can also be used with relevant identification equipment to form a system to achieve automatic identification, and can also be connected with other control equipment to achieve automatic management.

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

The barcode anti-theft of the supermarket is an electronic label (not all products are brought), the front is a barcode, the reverse side of the self-adhesive is a miniature coil, has been made into one, the barcode electronic label is divided into soft labels and hard labels, the cost of soft labels is low, directly adhered to the more "hard" goods, soft labels can not be reused;

Hard tags have a higher one-time cost than soft tags, but they can be reused, and hard tags must be equipped with a special nail extractor, mostly used for soft and easily penetrating items such as clothing.

Decoding requires a decoder, the decoder is mostly a non-contact device, there is a certain decoding height, when the cashier collects or bags, the electronic tag can be decoded without touching the degaussing area.

There is also a device that synthesizes the decoder and the laser barcode scanner together, so that the collection and decoding of goods can be completed at one time, which is convenient for the work of the cashier.

The detector is generally a detection system device at the entrance and exit of the shopping mall or the cash register channel. After receiving the correct amount due from a customer for a product, the cashier can authorize the product to legally leave a designated area by neutralizing the label affixed to the product.

When undecoded goods are taken out of the mall, an alarm will be triggered when they pass through the detector device (mostly in the shape of a door), so as to remind the cashier, customers and mall security personnel to deal with it in a timely manner.

Generally speaking, this involves the role of the stool guessing code, and this Yan Zao Huai style can be compiled into a good thick book.

The more common function is to scan the code to identify it, which is convenient for sales processing, or consulting.

Common commodity barcodes, such as cigarettes, beer, beverages and some fixed, quantitative or fixed volume packaging.
