chip allow it to emit a complex radiated light pattern.
MATRIX SYMBOLOGIES (2D CODES)
An arrangement of regular polygon shaped cells where the center-to-center distance of
adjacent elements is uniform. Matrix symbols may include recognition patterns which
do not follow the same rules as the other elements within the symbol.
