Economic globalization and Informatization for the manufacturing of competitive environment, development patterns and space has undergone profound changes, in response to these changes, manufacturing company for all aspects of the production, supply and marketing, implementation of ERP, SCM, CRM, management information systems, to help enterprises enhance operational efficiency and management level, enabling enterprises to deal with the ever-changing market changes and fierce competition in the market. Implemented various management information system in manufacturing enterprises, and acquired a certain efficiency increased, they found dominated by manual input of data acquisition becomes a variety of further enhancing the efficiency of the management information system bottleneck. Including bar code, magnetic stripe (card) technology, optical character recognition, system integration, RF technology, automatic identification technology such as voice-recognition and Visual recognition rise provides fast, accurate data acquisition and effective means of input, solved the slow due to manual data input, and high error rate caused the "bottleneck" problems. Thus automatic identification technology as a revolutionary high-tech, rapidly accepted.

       Bar code technology compared with other automatic identification technologies with high accuracy, fast, identify production cost low, thus widely used in commercial, postal, transport, and many other fields, such as supermarket bar code scanning cash registers settled, the post courier track and trace the use of bar codes. In fact, the manufacturing sector is the most important application of bar code technology, the most in-depth area. Bar code technology in developed countries, electronic and electrical appliances, machinery, automobile, apparatus suitable for barcode identification identification of large-scale manufacturing applications has reached a mature state, and application of bar code technology in the domestic manufacturing sector is still in its infancy, some well-known enterprises, including automobiles, motorcycles, electrical appliances, communications, IT and other industry leading enterprises with the implementation of ERP, started the progressive popularization and application of bar code technology.
