【Abstract】 In the automatic field of the production identification, in order to increase the application level of the Code Bar Technology in the quality, to broaden the application extension of the Code Bar Technology in the amount, it is pressed for larger information capability and higher information density in the limited geometry space to satisfy the protean needs of the modern times. Along with the development of the computer science, the process technology of the image identification, and encoding theory, the development and research of the Two-dimensional Code Technology is especially noticeable, and procured conspicuous achievement. By way of the new technology of the automatic identification in the future, Two-dimensional Barcode Technology will obtain wider development. In this paper it is introduced four kinds of Two-dimensional Code and the characteristic of them in the 2-D Code Maker.更多还原
