Scan head shines LED or laser light onto
barcodes
1.
2. Light reflects back off barcode into a
light-detecting electronic component
3. The cell generates a pattern of on-off
pulses that correspond to the black and
white stripes.
The code shown here ("black black black
white black white black black"), the cell
would be "off off off on off on off off.
4. An electronic circuit attached to the
scanner converts these on-off pulses into
digits.
5.The digital data from the scanner is sent
to a computer program.
