01. What is a 1D
barcode?
barcodelive.org

4.
1D BARCODE
Is a visual white & black pattern using
variable-width lines & spaces for
encoding information
barcodelive.org

5.
Pros Cons
1D scanners are
inexpensive
1D scanners have
good motion
tolerance with a wide
range
1D scanners can not
read 2D barcodes
1D barcodes may only
contain a limited
information amount

02. What is a 1D
barcode?

7.
2D BARCODE
Include a combination of dots & other
geometric patterns
barcodelive.org

8.
Pros Cons
2D scanners can read
1D barcode
2D scanners retrieve
more information
than 1D scanners
2D barcodes can be
read from any angle
2D scanners are more
expensive
2D scanners are less
accurate when
multiple barcodes are
in close proximity to a
product

03. 1D vs 2D barcode: What are the
differences?
barcodelive.org

10.
1D barcode 2D barcode
Information density Low High
Information capacity Small Big
Data storage &
capacity
Use spaces & variable width
lines to encode data
Use patterns of hexagons, squares,
dots, & other shapes to encode data
Ease of scanning Requirescanner's laser to be
precisely aligned with barcode
Omni-direction & orientation
reading
Database dependence
vs independence
Database-dependent
Don’t need to access a database to
use the encoded information
Applications
Scanned with conventional laser
or camera-based image scanners
Just be read by an imager

4. 1D vs 2D barcode: Which one
should you choose?
barcodelive.org

12.
Both have pros & cons
Although 2D barcodes can technically
replace 1D barcodes, they are more
fragile and not as fast
Both will be used for years to come
