ABSTRACT:
A two-dimensional code includes an array of data components. The array represents coded data and is positioned in a data area on a carrier depicting the two-dimensional code. A locator component is detectable by a reader and is substantially independent of an orientation of the carrier. The locator component is in a predetermined position with respect to the data area. An orientation component is detectable by a reader and has an asymmetric shape so as to indicate an orientation of the carrier.
