Tesco has started replacing traditional barcodes with QR codes across a range of its own-label products, marking what it describes as a UK supermarket first and one of the most significant changes in retail technology in decades.
The move begins with 13 lines of Tesco sausages, including Tesco Pork Sausages, Pork Chipolatas, Tesco British Pork Sausage Meat, as well as British Cumberland and British Lincolnshire sausages. While the change may appear minor on packaging, it signals a deeper shift in how supermarkets manage products, share information and reduce waste.
The rollout is part of a wider industry transition led by GS1, the global organisation responsible for barcode standards, which has set a target for retailers and manufacturers to be ready to accept QR codes as the next generation of product identification.
More information for shoppers, same experience at checkout
For customers, the shopping experience will remain largely unchanged. Products will still scan at the checkout as normal, but QR codes open up the option to access much richer product information using a smartphone.
By scanning the code, shoppers can view details such as nutritional content, sourcing and traceability, as well as additional features including recipes, product guidance and even competitions. This gives customers far more insight than traditional packaging allows, without changing how they shop.
According to GS1 UK, QR codes represent a new generation of barcodes that can connect physical products to digital information, helping create a more transparent and connected retail environment.
Tesco says this shift is not just about improving customer access to information, but also about building a smarter system behind the scenes.
Better stock control, targeted recalls and reduced waste
One of the biggest advantages of QR codes lies in how they improve stock management. By providing more detailed product data, Tesco can better understand what is happening in stores, allowing it to order more accurately and reduce unnecessary surplus.
Food waste remains a major issue in grocery retail, and even small improvements in forecasting and inventory control can have a large impact. Tesco believes the new system will help cut waste by improving efficiency across its supply chain.
The benefits are especially clear when it comes to product recalls. Under traditional barcode systems, retailers often have to remove entire product lines when an issue arises, even if only specific batches are affected.
With QR codes, Tesco can identify individual batches with precision. This means only affected products need to be removed, avoiding the unnecessary disposal of safe items and helping maintain availability on shelves.
The system also allows retailers to block the sale of affected products at the till, preventing them from being purchased once a recall is issued. In addition, Tesco can contact customers who may have bought specific items, improving response times and strengthening consumer trust.
These improvements are largely invisible to shoppers but represent a meaningful shift in how supermarkets operate day to day.
Peter Draper, Tescoâs development and change director, said the change may seem small but carries significant implications for the industry. He described the move to QR codes as âone of the most revolutionary retailing improvements in decades.â
He added that while customers will continue to shop and pay in exactly the same way, they will have the option to access much richer product information through their smartphones. Over time, he said, the technology could unlock new digital tools to help customers manage the food they buy and reduce waste at home.
Anne Godfrey, chief executive of GS1 UK, said Tescoâs adoption of QR codes across an entire product range marks a major step forward for UK retail. She noted that it demonstrates how next-generation barcodes can support a more transparent and connected future for both businesses and consumers.
The shift also highlights a broader transformation in retail, where packaging is no longer just a label but a digital gateway linking physical products to real-time information.
For Tesco, the move reflects a focus on long-term efficiency and innovation. By improving data accuracy, strengthening traceability and reducing waste, the company is positioning itself for a more technology-driven future in grocery retail.
While the rollout is currently limited to a selection of sausage products, it could expand across more categories over time if successful. That would mark a gradual but significant change in how products are tracked and managed across supermarkets.
For shoppers, the difference may start with a simple square code replacing a barcode. But behind that change is a system designed to make shopping more informed, supply chains more efficient and food waste easier to tackleâboth in stores and potentially at home.
