Abstract: QR code system is presently most popular encoding system. A QR code encodes the data by standardized encoding modes for storing the data efficiently. In this paper, a new 3-dimensional QR code generator for improving storage capacity of the encoded data is proposed. This 3-dimensional QR(Quick Response) code generator encodes three different data vectors simultaneously. When compared to the traditional greyscale QR code, the proposed QR code increases the storage capacity. In this method, for each data set a greyscale QR code is generated such a way that the three greyscale QR codes are generated. By combining these three greyscale QR codes, a new 3-dimensional QR code is generated.

Keywords: QR code, Storage capacity.
