Abstract
A tag with sufficient variability is generated. The tag facilitates quick location and processing within a facility. During generation, a matrix representative of a possible tag may be tested for sufficient variability. A two-dimensional matrix representing the possible tag may include different bit values at different positions. A variability metric of the matrix is performed to check the variability between adjacent elements of the matrix. This variability metric of the matrix is then compared against a variability threshold value. If the variability metric of the matrix falls below the threshold value, the matrix is flagged as unusable. If the variability metric of the matrix exceeds the threshold value, the matrix can be used to generate a tag with sufficient variability. Once generated, the tag can be presented and affixed to an item or object to help identify and locate the item within the facility.
