# QR codes for grocery stores

> Grocery QR codes live on shelf-edge labels, packaging and the till: extended product information at the shelf, loyalty enrolment at checkout, and coupons that skip the print run. The bigger shift is GS1's 2D sunrise — retail POS scanners are being upgraded to read 2D codes, aiming for the end of 2027.

## Three places a code works in a grocery store

| Code | Where | Why |
|---|---|---|
| Product information | [Shelf-edge label](/docs/ecommerce/qr-code-on-a-shelf-edge-label) | Provenance, recipes and reviews without touching pack artwork |
| [Loyalty enrolment](/docs/ecommerce/qr-code-for-loyalty-programs) | Till divider, checkout screen | Sign-up happens during the one idle minute of the visit |
| [Coupon](/coupon-qr-code) | End-cap and entrance signage | Weekly offers without a weekly print run |

## The shelf edge is a density problem

A shelf-edge label offers perhaps **2–3 cm** for a code read at **30–50 cm** — workable
by the 10:1 rule, but only if the payload stays short. A long promotional URL with
tracking parameters pushes the code to a higher version and shrinks each module below
what a phone resolves at arm's length in aisle lighting. Keep shelf URLs short, or the
label needs to grow.

## The 2D sunrise is the real story

Today a grocery product carries an EAN barcode for the till and, sometimes, a separate QR
for shoppers. GS1's **2D sunrise programme** is retiring that split: retailers worldwide
are upgrading POS scanners to read 2D codes, with the ambition that they can do so by
**the end of 2027**. The destination format is
[GS1 Digital Link](/docs/ecommerce/gs1-digital-link-for-retail) — one code that scans at
the checkout like an EAN and resolves in a shopper's camera like a URL. For grocers this
mostly arrives via suppliers' packaging, but store-printed labels for own-brand and
loose goods will follow the [same standard](/glossary/gs1-digital-link).

## Loyalty at the till, not the aisle

The till queue is the only point where every customer stands still with a phone. A
loyalty code on the till divider — straight into the sign-up form, no app-store detour
unless the app is genuinely the product — outperforms aisle signage that shoppers pass
at walking pace.

## What goes wrong

- Shelf-edge codes with long tracked URLs, too dense to scan at arm's length.
- A consumer QR placed next to the EAN on shelf labels, confusing self-checkout scans.
- Coupon codes left up after the offer ends — the printed code outlives the promotion,
  so the URL behind it must fail gracefully to a current-offers page.

## FAQ

### What is the 2D sunrise in retail?

GS1's programme to get retail point-of-sale scanners reading 2D barcodes — QR codes and
Data Matrix — alongside the traditional EAN, with an ambition of global readiness by the
end of 2027. It clears the way for one code to serve both the till and the shopper.

### How big should a shelf-edge QR code be?

At a typical 30–50 cm browsing distance, 3–5 cm is comfortable — but shelf labels rarely
offer that, so the real lever is payload length. A short URL keeps the code at a low
version with larger modules, which is what makes 2–3 cm workable.

### Where should a supermarket put a loyalty QR code?

At the till, where customers wait with phones in hand. Link the code straight to the
enrolment form rather than an app-store page — every extra step in a queue costs
sign-ups.
