Bar code knowledge
(A) an overview of bar code
Barcode (Product Code) is a product code, width and spacing by a group of parallel lines and the corresponding range of numbers. It can be said that a lot of information goods, through PV scan input Dian Nao, to determine a particular commodity-dependent countries, factories, Product Specifications, prices and other information Yixi Lie Chan Pin, greatly strengthen commodity Guanlixiaolv.
(B) packaging of the two bar codes
Since the advent of bar codes, to meet various needs, resulting in many of the coding system. But now the internationally recognized need for the packaging of the two, that UPC and EAN. Both the same type of coding system, each character by a few black and white stripes composed of narrow stripes down the middle with two out a bit about the bar code is divided into two parts. Although the two bar code can only express 0, 10 figures, but check with the high capacity, easy and reliable scanning.
1. UPC bar codes. UPC bar code was jointly organized by the United States and Canada, the “Uniform Code Council” (Universal Code Council, UCC) decided to use the IBM company's proposed Dalta-Distance-based and adopted. UPC Code (Uniform Product Code) as the United States, Canada unified symbol for product.
2. EAN bar code. EAN bar code is the EC “European Article Numbering Association” (European Article Numbering Association, EAN) absorbed the experience of UPC symbol for the establishment of the goods. The Association was renamed in 1977 as “International Article Numbering Association” (International Article Numbering Association). To date, the use of EAN bar codes have been dozens of members of the Association, in addition to Europe, the Asia, many countries use this code, China in July 1991 to join the Association. The existence of both the international coding system, therefore, our products are exported to the United States, Canada should use the UPC code, but exported to other countries and regions Zexu use of EAN codes.
(C) the composition of two bar codes
UPC and EAN bar codes while two belong to the same type, but the UPC code EAN code is formed on the basis, and has development and innovation, so technically EAN system, optical readers can read the UPC bar code system, while UPC system, optical reader can not read the EAN code. The composition of the two bar codes are as follows:
1. UPC composition. The 11-digit Universal Product Code and a check code form. Product code 1 digit coding system for the characters; the middle five figures that manufacturing firms in the later 5-digit code for the product.
2. EAN code form. By the representatives of the 12-digit product code and a checksum component. Product code for the country code top 3; the middle 4 digits for the production firm; last 5 digits of product code. EAN code country code assigned by the EAN headquarters management. China's country code is 690. Manufacturing firms by the EAN code branch distribution management in the country. China from the “Article Numbering Centre of China” uniform distribution of enterprise code. Product code by the manufacturer under the provisions of its establishment.
(D) the application of bar code
At present, the international market, especially the developed countries and newly industrialized regions has been generally used in the packaging bar code labels. In these countries, supermarkets in the region, almost all of the products are using bar code identification system, the customer selected product, the sales packaging of goods so long as the bar code facing the scanning reader, computer will automatically check prices and make total receivables. When the customer selected products have been scanned for all bar code, the computer also immediately reported the total and to print out shopping list. This store is equipped with only a small amount of sales can quickly and accurately complete the checkout, payment, etc., not only convenient for consumers, but also to improve the management of their store, improve sales efficiency and reduce cost of sales has created conditions. The wholesale, storage and transportation sector, through the use of bar code technology, goods classification, transport, find, check, is summarized quickly, accurately, to reduce the circulation of commodities and bank residence time, reducing product loss. Used in the packaging of goods to the international standard bar code, to shopping centers in the world Nei Xiao Shou, export control Zi Ji Chang Shang have Keneng time in the international market requirements, the Jiage dynamics and other relevant information conducive to continuous improvements commodity production and sales, thus further promoting international trade. Many countries and regions, in order to meet the needs of commodity circulation, limited product packaging must be printed bar code symbol, or not be imported. Therefore, the bar code on the international packaging applications has become an important part of modern packaging.
(E) the application of our application and management of bar code
December 28, 1988 established “Article Numbering Centre of China” (hereinafter referred to as “center”) is China's bar code technology, centralized management unit, the Centre on behalf of China formally joined the “International Article Numbering Association,” July 1 1991 the official date of the fulfillment of the rights and obligations of membership. “Center” aims to research and development of China's goods identification system, to standardization, and to achieve identification system compatible with international items, the promotion of exports. Its task is responsible for contacts with counterparts EAN and other items Bianma international institutions, the promotion, application and development of EAN items Biaozhi ???, unified organization, coordination, management Woguo barcode Gongzuo. “Center” is still in Guangzhou, Hubei, Jiangsu, Shanghai set up a “sub-centers” and provides not set up a “sub-center” of the region, from the “center” designation and cities with independent planning commission at the provincial level and the standardization body for a single region bar code work. Any use of product bar codes need to apply for the enterprise, all located in various places through the “sub-center” (not set up a “sub-center”, through “centers” designated and commissioned by the standardization bodies) to apply Article Numbering Center of China, from “center” allocation enterprise code.
Export production and management of enterprises need to use the barcode, the barcode to apply for available, from the “center” to the international bar organizations to apply uniform registration procedures, if the firm exports some products to the United States, Canada, while some are exported to other countries and regions, you should apply for UPC and EAN bar codes, and in accordance with the provisions of pay. Bureau of Technical Supervision regulations, China's commodities subject to the “center” bar code can be approved for worldwide general; get right to the use of enterprise bar code shall not be power to transfer or share with other enterprises, any enterprise or individual are not allowed to use other country (region) of the bar code or forgery, theft of other people's bar code, have been used in other countries or other areas of enterprise bar code, go to the local “sub-centers, or registered with the specified standards, and consultation on how to use our product bar codes.
