Two
dimensional barcodes (2D barcodes) have many attributes that make them a
good choice for many applications. As compared to linear bar codes
such as UPC or Code 128, two dimensional barcodes:
(1) Can encode more data, making them usable in “driver’s license” applications
(i.e. traditional applications that use a barcode information as a cross
reference number for data lookup) and in “portable data” applications (i.e.
applications where the data does not need to be cross referenced as all the
data is contained within the barcode).
(2) Can be damaged more than linear barcodes and still read.
(3) Are more efficient for encoding data. If you compare a linear code holding
20 characters vs. a 2D barcode with 20 characters, the 2D barcode is
smaller.
(4) Are significantly less susceptible to decoding errors.
There are many types of
2D barcodes, which are categorized into one of two types:
(1) Stacked Linear Barcodes. These
include:
(2) Matrix Codes.
These include:
- Aztec Code
- Data Matrix
- QR Code
- Maxicode
For decoding 2D barcodes, users purchase devices like the:
 
These devices have the
capabilities to read PDF417, Data Matrix, QR, etc. PDF417 is a specific
2D barcode type and is the latest development in the trend to pack the
greatest amount of data in the smallest space. PDF417 is the most
widely used 2D barcode today.
