 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.
