QR codes on retail shelf labels: help shoppers choose

A shopper picks up a bag of coffee, reads the roast description, then checks the next bag. They use a cafetière at home. One bag contains whole beans; another is ground, but the label gives them little help deciding whether it suits their brewer.

For an independent grocer, that is a useful place to try a QR shelf label. Give the shopper a specific invitation: “Scan for grind and brewing advice.” The page should open on the exact coffee in front of them, with the answer near the top.

QR codes on retail shelf labels earn their space when the information helps someone choose.

Giving shoppers brewing advice beside the coffee helps them choose a bag they’ll know how to use when they get home. Start with one question your staff already hear and one shelf where the answer needs more room than the price ticket allows.

Shelf-edge product information is already in use

In its March 2025 announcement, Asda described an electronic shelf-label rollout across 250 Express stores following a three-month Manchester trial. The labels include QR access to allergen information alongside displayed product pricing details. Asda’s announcement shows how retailers are putting extra product information within reach of shoppers at the shelf.

A small shop can try the information part with paper. An insert in an existing shelf holder can point to a web page just as a QR code on an electronic display can. Electronic price updates are a separate purchasing decision.

Build the answer before printing the label

For the coffee shelf, make a short mobile page for each product you include. Use the product name, bag size and a current pack photo so the shopper can confirm the match. Use your own photo or one you have permission to publish.

The first screen should say whether the bag contains whole beans or ground coffee, followed by the supplier’s advice on suitable brewing methods. If whole beans require a grinder, say so. Further down, add verified tasting notes and a short brewing guide for anyone who wants more detail.

Check each bag’s grind and brewing guidance against the supplier’s information before publishing the page.

Keep the page usable while someone holds a shopping basket:

• Open directly on the named product, without a search step.
• Put the answer promised on the shelf label above long brand stories.
• Use readable text rather than a photograph of a dense information sheet.
• Let shoppers read without creating an account or joining an email list.

If the page includes a price, assign someone to keep it current. Give a staff member responsibility for reviewing the page when packaging, supplier advice or the stocked variant changes. If you offer ingredient or allergen information, maintain it against current supplier information and keep package information and staff help available to shoppers who cannot scan.

Choose the simplest QR code that meets the need

A free static QR code is a sensible starting point if your shop already has a stable product-page address and its website analytics answer the questions you have. The printed QR code contains that address. You can keep editing the page at the same address, and existing website analytics can measure visits. Graklink offers a free static QR code generator. Its static QR codes do not provide Graklink scan counts.

A dynamic QR code lets you change the destination address after printing. That helps if a supplier moves its guide, you replace an external page with your own, or your website changes its product URLs. It preserves the printed QR pattern, but you still need to keep the page matched to the physical product and the promise on the label.

A Graklink dynamic QR code includes basic activity counts. The terms describe ownership for the lifetime of the service. Choose it for a small trial when an independent count will help you decide which labels to inspect or expand, even if their page addresses stay the same.

Counts can be useful even when you never change the destination. They can help you decide which labels deserve closer observation. They cannot tell you whether a shopper liked the coffee or bought it.

Make a label you can read and scan in the aisle

Start with the holders already fitted to the shelf. Measure the available insert area, then print on plain white paper or card compatible with your printer. Leave the product name and price easy to see. If the holder is too shallow for a usable QR code and prompt, use a larger adjacent shelf sign.

For an adhesive option, choose printable removable stock. Avery’s removable matte white paper labels are one supplier option for inkjet or laser printing. Check the selected size and printer compatibility before ordering. Test adhesion and removal on your shelf surface before printing a batch.

Use a dark QR pattern on white, with no artwork overlapping it. Leave the blank border intact: DENSO WAVE specifies four modules of clear space on every side, where a module is one small square in the pattern. Keep text and cut lines outside that border.

Print one actual-size proof. Put it inside the holder and scan it with different phones at the angle a shopper would use. Check glare from the cover, nearby products blocking the view and mobile reception in that aisle. Make the QR code larger if scanning is awkward. A successful scan from the design on your monitor does not test the printed label.

Add the shop’s name and a readable web address where space permits. Keep staff help available for shoppers without a working phone.

Run a small trial you can maintain

Choose a few coffees with distinct buying questions. Keep a simple record of each label’s product, destination, shelf position and installation date. Check those matches whenever the shelf is rearranged.

If you need to compare a regular shelf with an end display, give each placement its own dynamic QR code. Copies of one shared QR code combine activity; its count alone cannot identify which position someone scanned. Record your staff test scans separately so you can interpret small totals.

During the trial, check whether the label scans easily and whether the page answers the question without help. Note remaining questions. Review sales separately through your normal records, but do not treat a change in sales or a scan total as proof that the QR label caused purchases.

For the first shelf, included counts and direct observation may be sufficient.

If the trial becomes an ongoing shelf program, separate product pages can hold the brewing guidance while separate QR codes preserve counts by product or placement.

Pick one coffee today, write its grind-and-brewing page, and print one shelf label. Test it in position before making the rest.
