1. A visual marker that conveys information, the visual marker comprising:
a first set of markings that encode first data;
a second set of markings that encode second data, the second set of markings different than the first set of markings;
wherein markings of the first set differ from markings of the second set with respect to an appearance attribute, and wherein detecting or decoding the first set of markings selectively triggers a detection of the second set of markings, thereby identifying that the visual marker includes the second set of markings.
