GS1 has standards for five 2D barcodes that are currently in use across a variety industries. The two most widely recognised are QR Code (GS1 Digital Link URI) and GS1 DataMatrix barcodes which can both be used to store the Global Trade Item Number (GTIN) as well as information such as an expiry date or a serial number.

The GS1 DataMatrix is already widely adopted in the Healthcare industry.

The QR Code (GS1 Digital Link URI) can extend a product’s packaging, acting as a gateway to consumer information online such as ingredients, allergens and nutrition, sustainability information, recipes or usage instructions.
