From allergens and country of origin to QR codes and real-time offers, electronic shelf labels are quietly becoming one of the most useful tools in today’s supermarkets. Here’s how these tiny screens are reshaping the customer experience.
If you’ve wandered around a supermarket lately and noticed those small digital displays clipped under products, you’ve already met the rising star of modern retail: The electronic shelf label, or ESL. Once upon a time these gadgets were simply digital price tags, but today they’re turning into information hubs that can help shoppers make smarter, safer and more confident decisions. Allergens? Check. Product origins? Right there. Traceability details, QR codes and live promotions? All a tap, scan or glance away.
ESLs aren’t just a convenience for retailers to avoid the chaos of paper label updates; they’re part of a bigger shift in which physical stores meet digital intelligence.
Behind the scenes of why retailers are all in
The magic of ESLs isn’t only on the customer side: Stores benefit from accuracy, speed and reduced labour. But that’s not all. A growing group of retailers is partnering with platforms that turn physical shops into smarter digital spaces. One such platform provides electronic shelf labels for retail, transforming traditional stores into digital assets.
These platforms leverage automation, connected displays and sustainability tools to help retailers run cleaner operations while also offering customers richer information at the shelf edge. This is the behind-the-scenes digital backbone that makes live updates, allergen data and integrations of QR codes seamless. The tech isn’t just clever; it’s practical.
More than just a price tag
Allergens spelled out in plain sight
Food allergies are not a small issue, and customers have been asking for clearer information for years. ESLs now present a neat solution by displaying allergen details directly on the label, saving shoppers from squinting at packaging or frantically Googling ingredients in the aisle.
Picture yourself walking down the bakery aisle. Instead of turning bread packages around, you look at the ESL and notice icons or short text that indicates gluten, nuts or dairy. It’s quick, transparent and for customers who have allergies or dietary needs, it’s genuinely reassuring.
This is something retailers also love, since the information automatically updates via central software. If a recipe changes or a product switches suppliers, the allergen data updates in an instant without anyone needing to print out new signs. It keeps stores compliant and customers in the know.
Where in the world did it come from?
Consumers have become much more interested in the origins of their food. Provenance isn’t a hip marketing term anymore; it’s about sustainability, ethics and good old quality. ESLs make it easy to display country of origin, fishing zones, farming regions or production sites.
Take the fresh produce aisle. A digital tag under the tomatoes may show “Grown in Kent” or “Imported from Spain”. With meat or fish, you may see a whole lot more detail thanks to traceability systems feeding straight into the labels. Transparency is what’s the result, and customers like transparency.
QR codes for the curious
QR codes have quietly settled into everyday life, and ESLs have embraced them brilliantly. In lieu of trying to shoehorn lots of description onto the paper tag, there is often just a simple QR code added that unlocks extra layers of information when scanned with a smartphone.
Scanning a code may bring up nutritional breakdowns, recipe suggestions, sustainability certifications, product reviews, loyalty pricing and stock availability in nearby branches.
Helping shoppers to make informed choices
Real-time offers that actually make sense
Traditional paper labels can be slow to update and are often not in step with any digital promotions. ESLs solve that headache with price changes taking mere seconds. If the store launches a flash sale, drops clearance items or adjusts loyalty discounts, customers instantly see the right price.
No more walking up to customer service asking, “Is this actually on offer?” ESLs sync with the central system so everything matches up. It’s one of those small fixes that customers don’t always notice, but they definitely feel.
Accessibility features you don’t even notice
Some ESL models now support high-contrast text, larger fonts or icons that help visually impaired customers to better navigate along the aisles with less stress.
We’re also starting to see labels communicating with smartphone accessibility apps. A shopper might scan a code or tap their phone near the tag to hear product details read aloud. That’s a big step to making supermarkets inclusive, and it’s only going to get better as ESL tech moves forward.
Eco-friendly shopping gets a boost
If you’re someone who tries to shop sustainably, ESLs can point you in the right direction. Retailers can highlight low-carbon options, locally grown produce or certifications like Fairtrade and MSC.
And because ESLs themselves cut down on paper waste, reducing labour spent replacing thousands of tags, they are playing a small but meaningful role in greener store operations.
What shoppers actually do with ESLs
Stand back and watch people in a supermarket, and you’ll notice that ESLs are already part of the everyday shopping rhythm. Customers check allergens without contacting the product, scan QR codes for recipe ideas, compare prices using live promotions, pick local items because the origin data is right in front of them, and navigate categories quicker because digital labels are more visible and readable.
Even shoppers who don’t realise they’re using ESLs are benefitting from them. And that’s the sign of good tech: It blends in, makes life easier and doesn’t interrupt the flow.
