Product code is a kind of product code, which consists of a set of narrow and spaced codes.
Unequal parallel lines and corresponding numbers. It can represent a lot of information about goods, through
The photoelectric scanning is input into the computer, so as to judge the country of production, the manufacturer and the trade name specifications of the goods.
Grid, price and a series of commodity information have greatly improved the efficiency of commodity management.
(2) Two barcodes of commodity packaging
Since the appearance of bar code, many coding systems have been produced to meet various requirements.
But at present, there are two internationally recognized products used in commodity packaging, namely UPC and EAN.
These two coding systems belong to the same type, and each character consists of several black and white stripes.
There are two narrow stripes in the middle, which protrude a little downward and divide the bar code into left and right parts. These two kinds
Although the bar code can only represent 0 to 10 digits, it has a high inspection ability and can be scanned.
Simple and reliable operation.
1.UPC barcode. UPC barcodes are jointly organized by the United States and Canada.
The Universal Code Committee (UCC) chose IBM.
It is adopted on the basis of the Darta distance proposed by the company. UPC code (unified
Product code) as a unified identification of American and Canadian products.
2.ean barcode. EAN Barcode is the European organization of European Commodity Coding Association.
Will "(ean) learned U.
Product identification symbol established by PC experience. The association was renamed "China" on 1977.
International Article Numbering Association (ISBN)
Association). So far, the member countries of the association have used EAN bar codes.
Dozens, except Europe, many countries in Asia also use this code, and China adopted this code in 199 1 year 7.
Joined the association in May.
Because these two coding systems exist in the world, our products are sold to the United States and Canada.
Canada should use UPC code, while exporting to other countries and regions should use EAN code.
(3) Synthesis of two kinds of bar codes.
UPC and EAN bar codes belong to the same type, but because EAN code is
Formed on the basis of UPC code, and developed and innovated, so technically E
The photoelectric reader of the system can read the bar code of UPC system, and UPC system
Optical readers cannot read EAN codes. The two barcodes are composed as follows:
1 UPC consists of 1 1 universal product code and 1 parity code.
Composition. The 1 bit of the product code is the coding system character; Intermediate five-digit representation system
Make a trade name, and the last 5 digits are the product code.
2.2 composition. EAN code Verified by the product code representing 12 bit and 1 bit.
Code synthesis. The first 3 digits of the product code are the country code; The middle four digits are the number of the manufacturer; After ...
The five-digit number is the product code.
The country code of EAN code is assigned and managed by EAN headquarters. Our country code is 6.
90。 Manufacturer numbers are assigned and managed by EAN's branches in different countries. China is made up of "
China Article Coding Center uniformly issues enterprise codes. The product code is specified by the manufacturer.
Compile it yourself.
(4) The application of bar code.
At present, it is widespread in the international market, especially in developed countries and newly industrialized areas.
Use bar code labels on commodity packaging. There are several supermarkets in these countries in this area.
Almost all goods use bar code identification system. After the customer chooses the goods, the salesperson only needs to
By aligning the barcode on the commodity package with the scanning reader, the electronic computer can automatically inquire about the sales situation.
Pricing makes the collection accumulate. When all bar codes of the goods selected by customers are scanned, the meter
The computer will immediately quote the total price and print out the shopping list. In this way, the store only needs to be equipped with
A small number of salespeople can quickly and accurately complete the checkout, collection and other work, which is convenient for consumption.
It is also an article for the store itself to improve management, improve sales efficiency and reduce sales costs.
Pieces. As far as the wholesale, warehousing and transportation departments are concerned, through the use of bar code technology, commodity classification,
Transportation, searching, checking and summarizing are fast and accurate, which can shorten the circulation of goods and stay in the warehouse.
Leave time to reduce the loss of goods. Using bar codes that meet the international standards of commodity packaging,
It can be sold in shopping malls all over the world, and it is possible for exporters to master their products in time.
Relevant information such as demand situation and price dynamics in the international market is conducive to continuous improvement.
The production and sale of commodities can further promote the development of international trade. Many countries and places
In order to meet the needs of commodity circulation, bar code labels must be printed on the packaging of limited commodities.
Chi, otherwise not allowed to import. Therefore, the application of bar code in international packaging has become a packaging phenomenon.
The important content of modernization.
(5) Application and management of bar code application in China.
1988 12.28 "China article coding center" (hereinafter referred to as "the center").
This center is the centralized management unit of barcode technology in China, and it has represented China.
Officially joined ean International, and officially performed from 1 991July1.
Rights and obligations of association members. The purpose of "Center" is to study and formulate commodity standards in China.
Knowledge system, make it standardized and standardized, and realize compatibility with international article recognition system, and promote
Import and export. Its task is to contact EAN and other international article coding machines.
The construction, popularization, application and development of EAN commodity identification system, unified organization, coordination and management.
Bar codes work in China. The Center has also set up branches in Guangzhou, Hubei, Jiangsu and Shanghai.
Heart ",and stipulates that in areas where there is no" sub-center ",it shall be appointed by the provincial" center ".
Standardization agencies in cities under separate state planning are responsible for the barcode work in their own regions.
Where enterprises need to apply for the use of commodity bar codes, they must pass the "points" located in various places.
Center "(if there is no" sub-center ",the entrusted standardization machine shall be designated through the center".
Structure) to the China article coding center, the "center" unified distribution of enterprise code.
Enterprises that produce and operate export commodities need to use bar codes, and may apply to the above bar code institutions.
Please apply for registration from the Center to the International Bar Code Organization, if the enterprise has a department.
Sub-products are exported to the United States and Canada, and some products are exported to other countries and regions.
You should apply for UPC and EAN barcode at the same time, and pay the relevant fees according to the regulations.
According to the regulations of the State Bureau of Technical Supervision, China's commodities have applied to the "Center" for bar code approval.
Can be used globally; Enterprises that have obtained the right to use bar codes shall not transfer their rights or
Enjoy it with other enterprises, and no enterprise or individual may use goods from other countries (regions) without authorization.
Enterprises that have used barcodes of other countries or regions by using shape codes or forging or stealing barcodes of others.
Industry, to the local "sub center", or the designated standardization organization registration, and negotiate how to transfer.
Using commodity bar codes in China.
