GS1 DataMatrix, GS1 QR and GS1 Digital Link, the 2027 move to 2D at checkout.
GS1 DataMatrix
What is GS1 DataMatrix?GS1 2D Codes › GS1 DataMatrix
GS1 2D barcodes carry a product’s GTIN plus extra data, such as batch, expiry date and serial number, in a small square code. They are used to track medicines and medical devices, and retail is moving to them at checkout through the GS1 Sunrise 2027 effort. One code can serve the supply chain, the checkout and, with a web link, the shopper.
Choose GS1 DataMatrix for healthcare and industrial labels that are read by scanners. Choose GS1 Digital Link QR for consumer packs, so phones open a web page and checkouts still read the GTIN. GS1 QR with plain AI data and GS1 DotCode fit narrower cases, such as high-speed printing lines.
