QR codes for ecommerce and retail

Packaging, labels, reviews, returns and loyalty — the offline-to-online loop.

• Using QR codes to get more Google reviewsLink directly to Google's write-a-review endpoint for your Place ID, so the star dialog opens immediately instead of your listing. Put the code on the…
• Can a QR code replace the printed manual?When you can drop the printed manual for a QR code, when regulation and accessibility say you can't, and the hybrid quick-start pattern that usually wins.
• GS1 Digital Link for retail — one code for the till and the phoneHow the 2D retail migration works in practice — Sunrise 2027, the dual-symbol transition, resolver strategy, and what brands should put on artwork now.
• Measuring offline-to-online conversion with QR codesWhat QR analytics can honestly tell you — UTM-per-placement discipline, sessions vs scans, incrementality, and coupon redemption as ground truth.
• Preventing coupon QR code fraudA static discount code will spread — design for it or use tokens. Single-use validation, expiry, geo checks, and the fraud-versus-friction table.
• QR code on a product label — placement, size and separationWhere a QR code fits on a product label, how far to keep it from the EAN barcode, minimum sizes, and why new artwork should encode a GS1 Digital Link.
• QR codes for a market stallThe cash-light stall kit — regional payment QR schemes, lamination that survives weather, a price-list-with-codes sheet, and the same-phone caveat.
• QR codes for a pop-up shopThe pop-up ends; the codes shouldn't. Catalogue, payment and follow codes on temporary signage, sized for windows and A-frames, on a domain you control.
• QR codes for Amazon sellers — what inserts may and may not doAmazon's policies restrict review solicitation on inserts. What is allowed — manuals, registration, support — and how to design the safe insert.
• QR codes for asset taggingFixed-asset labels that last a decade — durable materials, ID-only payloads into your asset register, and the audit-scan workflow.
• QR codes for care instructions on apparel and textilesFitting a scannable code on a care label — woven vs printed label limits, what to put behind the code, and the EU Digital Product Passport crossover.
• QR codes for click and collectConsumer-presented pickup codes done properly — short token payloads, screen-scanning realities, locker codes and kerbside check-in flows.
• QR codes for endless aisle — rescuing the out-of-stock saleShelf codes that turn "not in stock here" into a ship-to-home order — customer phone vs kiosk, what the landing page must show, and per-aisle measurement.
• QR codes for Etsy sellersThe small-maker kit — thank-you card codes, care instructions, home label printing that scans, and a conservative read of Etsy's off-platform rules.
• QR codes for ingredients and allergen informationThe compliance line: allergen declarations must stay printed on the pack. What a QR code may add — full sourcing, per-batch data and recall communication.
• QR codes for inventory managementQR vs barcode for bins and stock, phone-scannable workflows, printing bin labels at scale, and running a stocktake on codes alone.
• QR codes for loyalty programmesEnrolment in one scan, wallet passes instead of apps, and POS-scannable member codes — the honest behavioural case against app-based loyalty.
• QR codes for nutrition informationExtended nutrition data behind a QR code — per-portion calculators, diet filters, the smart-label pattern, and honest expectations about scan rates.
• QR codes for product authentication — what works and what doesn'tAnti-counterfeit QR tiers compared — shared codes, unique per-unit codes, signed codes — and the honest limits: a copied code copies the authentic page.
• QR codes for product manualsLinking the manual instead of printing it — mobile-web vs PDF, per-language routing, and the setup-time trap: a router manual cannot require WiFi.
• QR codes for referral programmesReferral links as printed codes — unique code per customer for attribution, double-sided incentives, and the placements that reach an advocate's friends.
• QR codes for returns and exchangesLabel-free returns explained — the drop-off QR pattern, session tokens, return-portal codes on packing slips, and exchange-first flows.
• QR codes for serialised productsUnit-level codes done right — opaque serials resolved server-side, GS1 SGTIN framing, batch generation at production scale, and the use-case stack.
• QR codes for sustainability and recycling informationDisposal instructions differ by municipality — a QR code can geo-route where the pack cannot. Material data, take-back schemes and the greenwashing line.
• QR codes for warranty registrationCut warranty registration to one scan — put the serial number in the QR URL so the form arrives prefilled, and be honest about what the data is for.
• QR codes for wholesale cataloguesPer-SKU reorder codes in printed B2B catalogues — SKU-prefilled order links, line-sheet PDFs, trade-show editions and catalogue lifespan discipline.
• QR codes in the unboxing experienceInsert cards that get scanned — one call to action per card, the thank-you pattern, print specs for small cards, and the marketplace policy caveat.
• QR codes on a packing slipThe packing slip reaches a customer at peak engagement — order-aware codes for returns, reorders and support, with the order ID in the URL.
• QR codes on shelf-edge labelsSize floors for arm's-length scanning, e-ink ESL rendering limits, what shelf codes should link to, and surviving planogram churn.
• The EU Digital Product Passport and QR codesWhat the DPP under ESPR actually requires, why the data carrier will commonly be a QR code, the battery-first timeline, and what to prepare now.
