The invention provides location identification of machine-readable data on
data carriers. The invention is able to provide identification of the
location of the machine-readable data without the need to provide a
separate visual symbol or logo within the data carrier. As such, the
present invention provides location indication without having to occupy
additional space within the data carrier. The invention accomplishes
these attributes by systematically associating the machine-readable data
with a predefined portion of the visually perceptible information that is
included within the data carrier.
