The concept of code
Bar code is composed of a set of rules, empty and characters of the mark, "light" refers to a low albedo part, "empty" refers to the light, these high reflectivity and empty composed of data express a certain information, and to use specific equipment starts with computer, converts binary compatible with the decimal information. Mainly divided into one-dimension code and 2d barcode.
Due to the limited information capacity, one-dimension code is just to "items" logo, rather than on the "items". Therefore, the use of one-dimension code to depend on the existing database. To use the Chinese one-dimension code says, appear very inconvenient, and low efficiency. Two dimensional barcode to solve the one-dimensional barcode restrictive, because it has the characteristics of high density and high reliability etc, so can use it to represent data files (documents), including Chinese image etc. 2d barcode is large capacity and high reliability information storage, carry the most ideal and automatically with the method.
Bar code is by far the most economical, practical an automatic identification technology. Bar code technology has the advantages of the following several aspectsA. input speed: compared with the keyboard input speed, bar code is five times the keyboard input, and can realize real-time data input "."B. high reliability: keyboard input data error rate for three per cent, using optical character recognition rate for PPM, while using barcode technology ber than a million to one.C. collection of information: using traditional one-dimensional barcodes can be gathering dozens of character of information, 2d barcodes can carry more information of thousands of characters, and a certain degree of automatic correction ability.D. flexible barcode identification is practical: as a recognition method can be used alone, also can form a relevant identification equipment and automation system identification, also can connect with other control equipment automation management.
