Abstract
QR (Quick Response) codes are frequently used with progress of the Internet and introducing the QR decoding function in the cellar phone. A bar code shows an individual identification number (ID) by this number fundamentally. As the amount of information encoded by one-dimensional bar codes is limited, two-dimensional bar codes have been developed. This paper presents the dotted picture multiplexing method over the QR coding and the evaluation of the redundancy characteristics of the QR coding is also described. The prototype of the QR Editor for making the QR code with the dotted pictures, are made and the dotted pictures are confirmed by the cellar phone barcode.
