Quick Links
Barcodes have been the global standard for product identification since the 1970s. But that’s changing fast. QR codes and other 2D codes are gaining traction across retail, packaging and logistics.
Industry projections indicate that by 2027, many manufacturers will begin phasing in QR codes alongside traditional barcodes, with a dual-code period expected to last several years. Most experts agree that by 2030, QR codes will become the global default for product identification.
This shift aligns with regulatory updates from GS1, the global standards organisation overseeing barcode standards, which is currently developing guidelines to support 2D QR code integration while maintaining backward compatibility. Retailer adoption will vary, but many plan to upgrade point-of-sale systems to 2D scanning by 2027–2028, enabling a smooth, gradual transition.
What Are 2D QR Codes?
QR codes are a type of 2D (two-dimensional) code that store far more information than traditional 1D barcodes like UPC or EAN. Instead of holding just a product number, a QR code can also store:
- Expiry dates and batch numbers
- Allergen and ingredient info
- Recycling instructions
- Product authentication
- Links to how-to guides, videos, or digital receipts
What makes 2D QR codes powerful is their flexibility. They work for both checkout systems and smartphones, opening up new ways to connect physical products with digital content.
Brands can use them to enable traceability, reduce on-pack clutter and deliver dynamic, real-time updates all from a single scan.
Why the Shift Away from Barcodes?
Retail isn’t what it used to be. Consumers want more transparency. Retailers want better traceability. And supply chains need smarter tracking.
QR codes solve multiple challenges at once:
More Data in Less Space
QR codes can hold everything from allergens to compliance data without overwhelming the packaging.
Smarter Traceability
Batch numbers, production dates, and sourcing details can be embedded directly into the code, making it easier to trace products from factory to shelf.
Interactive Experiences
Link to care guides, recipes, tutorials or warranty registration without needing a separate app.
End-of-Life Info
QR codes can show how to dispose of or recycle an item properly, improving sustainability.
For brands, it’s an opportunity to turn packaging into a digital platform. For retailers, it means better visibility across every item sold.
Are Traditional Barcodes Going Away?
Not overnight, but the shift is underway. Industry leaders project that by 2027, many manufacturers will begin phasing in QR codes alongside traditional barcodes, with a dual-code period lasting several years. Most experts agree that by 2030, QR codes are expected to become the global default for product identification.
This timeline aligns with updates from GS1, the global standards organisation that manages barcode regulations. GS1 has been working on standards to integrate 2D QR codes, encouraging adoption while ensuring backward compatibility. They have indicated that full transition standards may be formalised by the late 2020s.
Retailer adoption rates vary by sector and geography. While some high-tech and luxury retailers have already embraced QR codes, many mass-market retailers plan to upgrade their point-of-sale systems to 2D scanning capabilities by 2027–2028 to handle QR codes efficiently. This gradual adoption allows supply chains and packaging manufacturers to update systems without disruption.
There’s already a shift toward using both 1D and 2D codes on the same product packaging. This dual-code approach gives retailers and brands time to update their systems gradually without disrupting checkout or logistics.
As point-of-sale systems become 2D-enabled and printing technology evolves, many manufacturers will start switching fully to QR codes. In the long run, 2D codes are expected to become the global default.
What This Means for Brands and Retailers
If you’re in retail, manufacturing or packaging design, now’s the time to start thinking about how QR codes fit into your workflow.
This isn’t just about swapping one barcode for another. It’s about future-proofing your product strategy.
Here’s how QR codes can work across key areas:
Packaging & Labeling
Add rich product info without clutter. QR codes can link to ingredients, certifications (e.g. Vegan, Organic) or usage tips while keeping the design clean.
Authentication & Anti-Counterfeit
Serialised QR codes can verify a product’s origin and detect tampering or fraud. Great for electronics, luxury items, pharmaceuticals, and high-value goods.
Warranty & Customer Support
Make returns, registration, and post-purchase support easier with scannable access to purchase history or help guides.
Supply Chain Tracking
Use dynamic QR codes to track products through manufacturing, shipping, and shelf placement. This improves stock rotation, traceability, and compliance.
Transparency & Sustainability
QR codes help tell your brand’s sustainability story. Link to impact reports, material sourcing, or climate commitments with just a scan.
Looking Ahead
The shift to 2D QR codes isn’t a trend. It’s a long-term change in how products are identified, tracked and experienced.
Upgrading your packaging to include QR codes gives your business a digital edge. Whether you’re improving traceability, offering smarter returns or creating engaging experiences, QR codes unlock new ways to connect.
