A bidirectional barcode scanning device that retains the same functionality in terms of reading information encoded on a barcode label as a conventional barcode scanner but that is also able to transmit information through a barcode label to a receiving device. The barcode label is affixed to a transparent substrate so that light from the barcode scanning device may be transmitted through the barcode and the transparent substrate to the receiving device. The light from the barcode scanning device contains an information signal that is decoded by the barcode label receiving device. |
