‍QR codes with GS1 Digital Link and GS1 DataMatrix are both 2D barcodes, but they are typically used for different purposes.

A QR code with GS1 Digital Link is ideal when people need to be able to scan with a smartphone and access digital information.
A GS1 DataMatrix is typically used when data from the barcode needs to be read and registered directly into systems and processes.

‍

In short: Which code fits your needs?

‍

If you are unsure about which 2D barcode to choose, contact GS1 Denmark before putting the code into production.

‍

Typically choose a QR code with GS1 Digital Link when:

• consumers or other stakeholders need to be able to scan with a smartphone
• the scan needs to lead to, for example, product information, user manuals, certificates, or campaigns
• the product's GTIN – and potentially other information – needs to be part of the link
• the code will also play a role in the supply chain and needs to be scannable at POS

QR codes with GS1 Digital Link uses GS1 Digital Link URI syntax, meaning it also contains a web address that includes (among other things) the product's GTIN.

Typically choose GS1 DataMatrix when:

• information from the barcode needs to be read by a scanner and registered directly into an IT system
• there is limited space on the product or packaging
• GTIN needs to be combined with, for example, a batch number, date, or serial number
• the code is to be used in a regulated or operational supply chain.

GS1 DataMatrix uses GS1 element string syntax. It therefore does not contain a web address and does not in itself provide direct web access.

What is the difference between GS1 DataMatrix and Data Matrix with GS1 Digital Link?

Terminology is important here: GS1 DataMatrix and Data Matrix with GS1 Digital Link are not the same.

GS1 DataMatrix contains structured data identified using GS1 Application Identifiers. This could be, for example, a GTIN, batch/lot number, and expiration date. The data can be read and used directly in relevant systems, but the symbol itself does not provide access to online content.

Data Matrix with GS1 Digital Link instead contains a web-based GS1 Digital Link URI, where the GTIN and, if applicable, batch/lot and expiration date are included in the URI itself. When the link is opened, the user can be redirected to digital product information.

The principle is the same as for a QR code with GS1 Digital Link. However, Data Matrix is not as widely supported by standard smartphone cameras as QR codes, and may therefore require a specific app to scan the code and open the digital content. For this reason, it is used less frequently.
