There is a linear photodiode within the scanner head. This photodiode can read the reflected light off the lines on the barcode. This reflection is a digital image that is then scanned electronically within the devise. When the image is scanned electronically, each bar on the barcode is converted to the corresponding number or letter. Barcode scanner are now available via rental service also.
