Data Matrix and QR Code (quick response) are both 2D codes that were developed
around the same time. Data
Matrix was developed in 1989 and QR Code in
1994.
A Data Matrix barcode can hold up to 2,335 alphanumeric characters; QR Code holds up to 4,296 alphanumeric characters. Data Matrix code is believed to be the more secure (less hackable) code and is favored where high security is deemed important.
Both barcodes store considerably more information than the older 1D barcodes. For some time it seemed like Data Matrix was becoming the standard 2D barcode in North America as many organizations and various levels of government were using it. However Data Matrix wasn't designed to use Kanji (Japanese characters) and QR Code was, so of course QR Code became the prominent barcode throughout Japan.
QR Code
The
Japanese really embraced QR barcode technology and were
using QR code in all kinds of unique applications. Their easy adaptation
of barcode technology
and related excitement around the use of barcodes has flowed through
Europe and is now working it's way across North America.
In many applications, QR Code is fast becoming the most prominent barcode technology.
