2. Benefits of barcode readers
3. Components of a Barcode Scanner
4. Types of Barcode Scanners
5. Types of additional scanner
hardware

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.

1D Image Scanners
Capture a barcode image
using CCD technology.
The image is captured and
converted into data by a
network of hundreds of
light sensors
Can read damaged barcodes
Types of Barcode Scanners
2D Camera Based Scanners
Can read both horizontal
and vertical 2D barcodes.
Can also read barcodes
from the screen of a
computer or phone.
