Abstract
A system includes a substrate having a coded data pattern disposed on a surface thereof. The coded data pattern encodes a plurality of Reed-Solomon symbols defining tag data and an orientation of a layout of the tag data. An optically imaging sensing device configured for imaging part of the coded data pattern; determining the orientation of the layout of the tag data; and decoding the tag data contained in the imaged part of the coded data pattern.
