A stand costs more per square metre per day than almost anything else a company rents, and the two things that decide whether it paid off are how many qualified conversations you had and how many of them you could still reach a week later. Paper fails at both: business cards get lost in a tote bag, and a printed catalogue is left in the hotel room. A small set of codes turns the stand into something measurable — and because they are dynamic, the panels you paid to print survive to the next show.

The six codes a stand actually needs

Resist the urge to put one code on everything. Each code should answer one question a visitor has at that exact spot; the counter lead form and the product spec sheets are the two that convert.

Where a code earns its place on an exhibition stand
WhereThe code opensStatic or dynamic
Back wall, top third of the panelCompany page written for a phone, read from the aisleDynamic — one code per show
Product plinth, demo unitSpec sheet, price list, demo video for that productDynamic — one code per product
Counter, next to the staffLead form: name, company, what they needDynamic — the form changes between shows
Printed catalogue, flyer, tote bagThe PDF catalogue, so nobody carries paper homeDynamic — the PDF is replaced each season
Staff badge and business cardContact card that saves straight into the phoneStatic vCard is fine, dynamic if the role changes
Talk slides, workshop handoutSlides, follow-up offer, meeting booking pageDynamic — one code per talk

Lead capture that beats a clipboard

The paper sign-up sheet has the same flaw everywhere: it is filled in by hand, half illegible, and typed up days later when the momentum has gone. A code at the counter that opens a short lead form — name, company, email, one line on what they are looking for — lands in your system while the visitor is still talking to your team, and the follow-up can go out the same evening instead of the following week.

Keep the form to four fields and make it one-handed on a phone: people are standing, holding a coffee and a bag. Add a single optional dropdown for interest so the follow-up can be sorted, and nothing else.

The catalogue nobody has to carry home

Printed catalogues are heavy, expensive and mostly thrown away at the airport. A code — on the flyer, the counter, the product panel — that opens the PDF gives the visitor the whole thing at zero weight, and gives you something a paper catalogue never could: a count of how many people wanted it. Make it dynamic and you replace the PDF next season without reprinting a single panel.

One code per product, not one for the company

A single code on the back wall pointing at your homepage tells you nothing and helps nobody. A code on each product plinth, opening that product's spec sheet, price list or thirty-second demo video, answers the question the visitor has while they are looking at the thing — and the scan report then tells you which product drew the crowd, which is the single most useful number a stand can produce.

Meetings booked before the visitor leaves the aisle

For anything with a long sales cycle, the goal on the stand is not the sale — it is the next meeting. A code that opens your booking page with real available slots lets the visitor put a call in their own calendar while standing in front of you, which is far more reliable than "send me an email". Print the same code on the talk's last slide and on the business card your team hands out.

Print widths for panels, walls and banners

Three traps specific to exhibition halls. Stand graphics are usually printed on glossy laminate under hard spotlights, which reflects straight into the camera — ask for matte. A code in the bottom third of a back wall is blocked by your own visitors all day, so put it in the top third. And never place a code across the seam between two panel sections or on a fabric wall that ripples: both break the pattern.

The report that tells you which show paid for itself

Use one code per show, even for the same destination. Then the scan report separates Cologne from Milan by day and hour: which show produced scans, which product panel drew them, whether the second day was worth staffing, how many leads arrived per hundred scans. That comparison, kept over a season, is what turns exhibition spend from a habit into a decision.

One practical warning about the hall itself: mobile data in exhibition centres collapses when 20,000 people are in the building. Make the pages behind your codes light — no heavy video autoplay, no 10 MB hero images — and test them on the stand on the morning of day one, on a phone that is not on the exhibitor Wi-Fi.

Perguntas frequentes

Where should the QR code go on an exhibition stand?
In the top third of the back wall, so your own visitors do not block it, plus one on the counter for the lead form and one per product plinth. A single code on the whole stand wastes the most useful data you can collect.
How big must a QR code be on a stand back wall?
About 90–120 mm wide to be scanned from the middle of the aisle at 3–4 m, and 180–250 mm on a banner hung 6–8 m up. Ask the printer for matte laminate: gloss under spotlights reflects into the camera.
Can I add everyone who scans my code to my mailing list?
No. A scan is not consent. Collect the address through a form that states what you will use it for and includes an explicit marketing opt-in — in the EU that is the difference between a lead and a complaint.
Should I use a different QR code for each trade show?
Yes, even when the destination is the same. One code per show lets the scan report compare events by day and hour, so you can see which show and which panel actually produced interest.
What if mobile data does not work in the exhibition hall?
Assume it will be slow: halls with tens of thousands of visitors saturate the network. Keep the destination pages light, avoid autoplay video and large images, and test on the stand on the first morning with a phone that is not on the exhibitor Wi-Fi.
