An Optical Recognition (OR) code mark is provided. In one example, an OR code includes a segmented portion and a registration mark (e.g., in the form of an iris or pupil) positioned relative to the segmented portion. The OR code mark, e.g., as part of the segmented portion, includes a calibration region having 3 or more different colors, where each color is associated with a number (e.g., “0”, “1”, “2”, . . . “n”, and so on). The segmented portion of the mark is further colored (with the at least 3 different colors of the calibration region) to encode the segments. Accordingly, the OR code can be detected using the registration mark and calibration region to identify and assign values to the segmented regions and decode the mark. |
