1D to 2D Barcode Shift Hits Retail Industry

GS1, the global barcode standardization organization, has called for a worldwide change in the retail industry in response to the rise in information demand. To answer that demand, GS1 now advocates using 2D QR barcodes on (consumer) goods and packaging. Major industry leaders have already embraced the change and will support the transition to QR codes by 2027.

The change to 2D codes is not new. As 2D codes have larger storage capacities and allow for more data to be processed in different ways, the healthcare industry already uses 2D codes to not only check out medicine at the counter but also to cross-reference its ingredients for allergies and contraindications. Now, in retail too, consumers want to know more about what they’re buying. Manufacturers can use 2D codes to provide all relevant information, such as detailed lists of ingredients or materials, expiration dates, and recycling instructions.

Despite the rise of 2D QR barcodes on packaging and consumer goods, 1D barcodes aren’t going away any time soon. That’s why it's recommended to invest in a solution that covers multiple code options during the transition period. The scanners need to be able to read both types of code at the same time but handle the data differently.

For a smooth transition to QR codes, retailers are advised to ensure their POS systems are equipped with scanners that read both 1D and 2D codes simultaneously for uninterrupted scanning. 1D barcodes can still be used with existing systems for fast check-out, while the 2D code can be used to send or trigger additional information to systems. We’re already seeing major retailers testing the technology at their point of sale.
