2D barcode overlays
Embodiments herein describe a 2D barcode that overlays text or graphics (e.g., another barcode) while permitting the underlying text or barcode to be read by a user or a barcode scanner. Further, the embodiments herein describe techniques for separating the overlaid 2D barcode from the underlying text or graphics so that the barcode can be identified and decoded. In one embodiment, the blocks forming the 2D barcode are printed (or displayed) using a shade of a color while the text or graphics are printed (or displayed) using a darker shade of that same color.
