Why the retail industry is migrating to GS1 2D QR codes
For over 50 years, 1D linear barcodes (UPC/EAN) have served as the foundation of retail checkout. However, linear barcodes can only carry a product’s GTIN. Today’s consumers and supply chains require far richer information — including batch numbers, expiration dates, organic certifications, and digital user manuals.
GS1 Digital Link QR codes solve this challenge by replacing or augmenting 1D barcodes with a single 2D symbol that satisfies point-of-sale checkout scanners while providing a rich mobile web experience for smartphone users.
Executing a Dual-Symbol Packaging Strategy
During the transition window prior to January 2027, brands are encouraged to adopt a dual-symbol approach on retail packaging. By placing a GS1 Digital Link QR code alongside the existing UPC/EAN barcode, product packaging remains fully functional across older laser registers and upgraded camera-based 2D scanners.
