For retailers

A till that knows not just what it scanned, but which batch it came from

A linear barcode carries one fact: which product this is. Everything else, the date and the batch, lives on paper and in the heads of the people on the shop floor.

Where the margin leaks

Expired stock goes through the till

Date checks on shelf are manual, so they run late. You pay in returns, complaints and a shopper who goes elsewhere next time.

Recalls take everything with them

Without a batch number there is no way to say which units are affected, so the entire product comes off every shelf.

Markdowns by feel

The decision to discount is made without hard information about the real shelf life of that particular delivery.

What the 2D code changes

The till checks the date

The expiry date arrives with the code, so the system can block the sale or start a markdown a few days earlier.

Recall down to the batch

The batch number lets you pull exactly the units in question and document it if an inspector asks.

The hardware usually stays

Most scanners have read 2D for years. The cost sits in checkout and warehouse software, not in the guns.

Tesco, April 2026

First UK supermarket to move an entire own label range onto 2D codes. They started with sausages. Carrefour is doing the same across its private label.

11 percent, then a third more

Share of GS1 UK members who had already rolled out GS1 powered QR codes by May 2025, with another 33 percent planning it within a year.

562 complaints, then none

Unreadable code complaints logged by a supplier to Polish retailer Żabka over nine months in 2022. Three months after switching to 2D, the count was zero.

What happens when somebody scans this code

There is a real resolver running underneath, not a recording. Pick a situation or scan the code with your phone and you will see exactly what a shopper sees at the shelf.

Picks up the juice and scans the code

A product page opens in their language: ingredients, allergens, origin, the date from their own pack and sorting instructions. All on one screen.

What you get out of it

You get contact with a buyer who is otherwise invisible to you when a retailer owns the sale.

What the shopper sees

Scan it with your phone. The same code serves the till and the shopper.

It is the same code in every situation. What changes is who scans it.

Situations rotate every few seconds. Click any of them to stop.

Do we need new scanners?+

Rarely. Start with an audit of what is already at the tills. In most chains the hardware is ready and software turns out to be the bottleneck.

What about products without a 2D code yet?+

They work as before. During the transition packs carry both codes and the till handles either one.

How big is the change in our systems?+

The largest item is finding a place for batch number and expiry date where today there is only a product identifier. That is a data model and process change, planned in quarters.

Send us one code, we will send back an analysis

A photo of the pack or a sample of your product data is enough. We will tell you what is correct, what will break at the till and what is missing for the product passport. Expect a reply within a few working days.

This is not a newsletter sign up. We write about the thing you asked for.

The analysis is free and commits you to nothing. If it turns out you do not need this yet, we will say so.

Sunrise 2027 is not law. It is an industry ambition, and the linear barcode stays on packs until 90 percent of checkouts can read 2D. What is law is the product passport: from 18 February 2027 batteries above 2 kWh placed on the EU market need a passport reachable through a QR code, with textiles and tyres queued behind them. The infrastructure is the same in both cases, so one project settles both. Anyone selling you this as a legal obligation today is stretching the truth.
