Pick up almost any specially marked pack in a Coles or Woolworths aisle right now and there’s a decent chance it carries a QR code somewhere near the promotional flash. Ten years ago the same pack would have said “visit our website and enter the code.” The destination hasn’t changed much. What’s changed is how the shopper gets there — and how little patience they have for anything that slows the trip down.
We’ve delivered enough scan-to-enter campaigns at Trevor Services to have a view on where QR entry earns its place, and where it just relocates the friction. This piece covers the mechanic itself: what QR entry actually is, where it fits in the entry chain, and the delivery details that decide whether the scan converts.
What is QR code promotion entry?
QR code promotion entry is a mechanic where a shopper scans a QR code — printed on pack, on a shelf talker, or at point of sale — and lands directly on a promotion’s entry page, instead of typing a URL. The QR code is the route into the promotion; validation of the purchase still happens separately, usually through a unique code, a receipt upload, or both.
That distinction matters more than it sounds. A QR code on its own proves nothing about a purchase — anyone can photograph one on the shelf and scan it from home. So in a purchase-to-enter promotion, the QR gets the shopper to the form, and something else does the verifying. The two jobs are often confused in briefs, and campaigns that treat the scan as proof of purchase tend to discover the difference during the fraud review rather than before it.
Where the scan fits in the entry chain
The classic Australian on-pack entry flow is alive and well. Take the recent Victoria Bitter Knock Off Clock promotion: buy a specially marked case, visit the promo site, fill in the entry form, and key in the unique code printed inside the case. It’s a well-built campaign — winning moments, instant prizes, a game layer — but the route in still asks the shopper to remember a URL and type it later, probably at home, probably after the moment has passed.
QR entry compresses that route. The scan happens where the intent is — in the aisle, at the fridge door, on the couch with the pack in hand — and the entry page opens in seconds. In The Shelf Truth we describe the shopper’s decision as the 3-Second Equation: reward and belief, divided by friction. QR entry doesn’t change the reward, but it takes a real bite out of the friction term, because the gap between “I’ll enter that” and actually entering is where most entries quietly die.
It also matters where the scan physically happens. A shopper scanning in-store is standing up, holding a basket, on retail wifi that may or may not cooperate. A shopper scanning at home has time, a couch and their wallet nearby. The entry experience should be designed for the harder of the two — which is a shopper-context question as much as a fulfilment one, and the kind of thing shopper marketing thinking is built to answer.
The landing page is the real mechanic
The scan is the cheap part. What loads next decides the conversion rate, and this is where we see the most variation between campaigns that look identical on pack.
A QR code can carry more than a bare URL. Batch-level parameters can tell the entry page which pack size, retailer or state the scan came from, so the form arrives partly pre-answered and the promoter gets channel data without asking the shopper a single extra question. Serialised QR codes — a unique code per pack, embedded in the link itself — go further and collapse the “now type the 12-character code from inside the lid” step entirely. They cost more to print and manage, but on instant win campaigns, where the whole promise is immediacy, that trade is usually worth pricing.
Whatever the QR carries, the form it opens should be ruthless. In the campaigns we run, every field on an entry form costs entries — we’ve written before about cutting entry friction, and the compounding drop-off across six or seven fields is brutal. A shopper who has just scanned in an aisle will give you a name, a mobile, an email and a photo of a receipt. They will not give you their household size and preferred contact window. Nothing undoes the good work of a frictionless scan faster than a form built by a data wishlist.
How does GS1 Sunrise 2027 change on-pack QR codes?
Sunrise 2027 is a global GS1 initiative for retailers to be able to scan 2D barcodes — including QR codes built on GS1 standards — at the point of sale by the end of 2027, alongside the familiar 1D barcode. GS1 Australia is guiding local retailers through the transition, and the global industry endorsement reports pilots in 48 countries representing 88% of the world’s GDP.
For promotional marketers, the interesting part is GS1 Digital Link: one QR code that a checkout scanner reads as a product identifier and a shopper’s phone reads as a web link. Under the 2D-in-retail guidelines, that link can resolve to different destinations — product information most of the year, a promotion entry page during a campaign window — without reprinting the pack. On-pack real estate is contested territory, and a promotional QR that borrows the product’s own barcode rather than fighting for its own square of the pack changes the conversation with both the pack designer and the retailer. It’s coming whether promotional teams plan for it or not; the ones who plan for it get the entry route for free.
What goes wrong in delivery
The failure modes are unglamorous and almost all preventable. Codes printed too small, too low-contrast, or wrapped around a curved surface that phone cameras refuse to read. A generic QR pointing at the brand homepage instead of the entry page, adding back the navigation the QR existed to remove. Entry pages that assume store wifi will behave. And the quiet one: QR codes on packs that outlive the promotion, still scanning months later into a dead URL — worth deciding at the start what that link resolves to in March, not discovering in March.
Then there’s the entry-management layer behind the scan. Because QR entry is low-friction by design, it’s low-friction for the wrong people too, which is why the standard controls matter more here, not less: one use per unique code, per-person entry caps, velocity checks on repeated submissions from the same device or address. The VB terms above cap entries at one per day and five per promotion — limits like those are only enforceable if the platform behind the form is actually counting. That back end is the part of the mechanic nobody sees on the pack, and it’s most of what Trevor Services builds. It’s also where the accumulated data starts paying forward: Trudy, Trevor Services’ predictive promotional intelligence platform, draws on the entry patterns from campaigns like these to help clients decide where a QR route will genuinely lift entries and where a receipt-upload flow will validate better.
And the boring essential: purchase-to-enter promotions with prizes above the thresholds still need permits in the regulated states — the VB promotion runs under ACT, NSW and SA authorities, listed in its terms. The QR changes how shoppers arrive. It changes nothing about what the promotion owes the regulator.
Worth doing well
QR entry is close to a free kick: the shopper already has the scanner in their pocket, the print cost is negligible, and the friction saving is real. But it only pays if everything after the scan is as light as the scan itself — a fast page, a short form, validation that works the first time. If you’re weighing up a scan-to-enter route for an upcoming campaign, we’re happy to talk it through.
