Tesco Leads the Charge in UK Supermarket Barcode Revolution
For over five decades, the familiar beep of a barcode scanner has been a staple of retail checkouts worldwide, from supermarkets to clothing stores. However, this iconic technology is now on the verge of a major transformation. Retailers are beginning to abandon the traditional linear barcodes in favor of modern, square-shaped QR codes, also known as 2D barcodes. This shift is set to redefine how consumers interact with products, offering a wealth of new information at their fingertips.
The End of an Era for Traditional Barcodes
According to GS1, the sole authorized provider of Global Trade Item Numbers (GTINs), which power every barcode, the move to QR codes is driven by their superior data capacity. Traditional barcodes are limited to storing just seven specific pieces of information: item name, manufacturer, product type, size, color, weight, and price. In contrast, QR codes can hold significantly more data, including detailed ingredients, allergen warnings, and even recipe suggestions for food items. This enhancement promises to empower consumers with deeper insights into the products they purchase.
Anne Godfrey, chief executive of GS1 UK, reports that nearly half of British retailers have already updated their checkout systems to accommodate QR codes. "Very soon we will say goodbye to the old-fashioned barcode and every product will just have one QR code that holds all the information you need," she told Mail Online. "The old barcodes do what they say on the tin — they go beep, tell you the price and get you out of the store. But today’s consumers want much more information about the products they buy."
Tesco's Trailblazing Trial and Industry Adoption
Tesco has emerged as the first retailer to implement this change on a significant scale. The supermarket giant is currently trialling QR codes on select own-brand fresh produce and meat products, such as lemons, limes, steaks, and sausages. This pilot program marks a critical step in the broader industry transition. Other major brands, including L’Oreal, Unilever, and Procter & Gamble, are also adopting 2D barcodes, signaling a widespread shift across the retail sector.
The technology, while still in early development, is designed to be scannable both at traditional tills and on mobile devices. QR codes gained popularity during the pandemic for contactless menu ordering in restaurants and bars, and they are increasingly appearing on product packaging to provide additional information or link to websites. "By combining two of the most important inventions of the 20th Century, the internet and the barcode, the next generation of barcodes will connect physical products to the digital world," Godfrey explained to Metro. "This allows consumers to access virtually limitless, real-time information about the products they buy at the scan of a smartphone – helping them make more sustainable, safer and smarter purchasing decisions."
Accessibility Benefits and Business Advantages
The transition to QR codes is not just about convenience; it also addresses important accessibility issues. Theresa Lindsay, group marketing director at consumer finance brand Novuna, highlights that these new codes can assist visually impaired individuals by providing audio assistance when scanned. "QR codes will be a more powerful tool for consumers to decide whether a product is right for them, creating greater trust and communication between brands and customers," she says.
From a business perspective, QR codes offer dynamic opportunities for smaller retailers to convey their stories and personalize the product experience, especially when limited by packaging or store size. "QR codes open a range of opportunities for brands and customers, going beyond simply tracking a product’s sell-by date," Lindsay adds. "By linking an action to the QR code, which is then evaluated to understand how consumers engage with a product or initiative, brands can learn directly from customer shopping interactions how to better meet their needs."
Historical Context and Global Rollout
The barcode, invented by Norman Joseph Woodland in the late 1940s and refined by George J Laurer at IBM, was first scanned on a packet of Wrigley’s chewing gum in Ohio in 1974. It reached the UK in 1979 on a box of Melrose tea bags. Now, as brands like PepsiCo, Amazon, and Walmart join the movement, a full international rollout of QR codes is predicted within the next year, with traditional barcodes likely phased out by 2027.
Anne Godfrey cautions that retailers must adapt quickly to avoid being left behind. "We won’t celebrate the death of the humble barcode, but it is time to say a long goodbye to it," she remarks. With Tesco at the forefront, this technological evolution promises to enhance consumer empowerment, accessibility, and business innovation in the retail landscape.
