The Difference Between Data Matrix and QR Code

Data Matrix and QR Code (quick response) are both 2D codes that were developed around the same time. Data data matrix barcodeMatrix 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.
