ABSTRACT:
A two-dimensional (2D) tag for reading with an optical reader. The tag has a plurality of dot positions, a locator component used to locate the tag by the reader, an orientation component used to sense an orientation of the reader relative to the tag, and a data area to be read by the reader. The tag is represented by a tag format structure that contains an entry for each of the plurality of dot positions. An entry in the tag format structure can specify whether the dot position is part of the locator component or whether the dot position is part of the data area.
