• When used, the scanning head flashes the barcode with an LED light. The light then bounces back off the barcode into a photoelectric cell, which is a light-detecting electronic component. 
• The photoelectric cell produces an on-off pulse pattern that corresponds to the black and white stripes when the scanner passes by the barcode.
• The scanner's electronic circuit turns these on-off pulses into digits.
• The scanner's digital data is transmitted to computer software, which generates the final barcode.
