Han Xin Code

Han Xin is a 2D bar code symbology intended particularly for the representation of Chinese characters. It appears to be based on the GB18030 character encoding system, which encompasses Chinese and a number of other characters from Unicode. It is a proprietary system whose formal spec is paywalled at a $147 price.
