Design and realization of 2D color barcode with high compression ratio

With the development of barcode applied fields, the data capacity expressed by barcode is required to increase. Both enlarging the barcode size and enhancing the barcode density have some limits. We design a 2D color based on 2D barcode. This barcode is added color, and the encoded method for Chinese character is applied according to the usage frequency. Comparing with other 2D barcode, the 2D color barcode proposed in this paper has high compression ratio for Chinese character, and alpha-numeric data.
