QR codes in event marketing: offline finally becomes measurable

QR codes have had a remarkable second life. What used to be a technical novelty is now ordinary — at the restaurant, at check-in, at the ticket desk. For an organiser that means one thing: offline can be measured now, and it should be.

Why they work now

Habit. The pandemic turned the QR code from a nice-to-have into a default. People scan without instruction and without hesitation, and that has not gone away.

No gap to cross. Nobody types a long address. Scan, event page, ticket — no friction, no detour.

Measurability. Posters, flyers, print ads and banners used to resist evaluation entirely. Now they can be read like an online campaign.

What you get out of it

A dynamic code tells you how often it was scanned, when, and roughly where from. That turns a flyer into a channel with numbers behind it. Which districts carry? Which banner produces interest? Which venue generates the scans? Those were questions you previously had a hunch about.

And because each code counts for itself, you can compare: one on the poster, one in the magazine, one on the hoarding. Evidence instead of instinct — and a clear call to action next to it (“10% off today”) shortens the path to a ticket more than any printed URL.

Static or trackable

A static code forwards. A trackable one reports. In between sits the difference between using them and deploying them: measuring campaigns, comparing offline channels, proving a return, and putting budget where the evidence is. With advertising costs where they are, that is not a luxury.

Why this is built in

External QR services cost somewhere between €5 and €35 a month depending on tracking and scan volume — €60 to €420 a year, and more once several events run at once. Plus another login, a separate set of numbers, and one more tool somebody has to remember.

In Entrello codes are made in the Campaign Manager, in the timeline itself: you plan the campaign and produce the code in the same step. A code can belong to a single event, to a group of events, or stand on its own. There are templates for the usual cases:

• a direct link into your ticket shop
• promoting a voucher campaign that is already running
• newsletter sign-ups
• a freely defined link

Every code is trackable by default and reports scans, performance and location in real time.

One habit worth forming: give every code an internal name — “poster, Graz city centre, March”. When four offline campaigns are running at once in the summer, that is the difference between an analysis and a puzzle.

Where they earn their place

• Posters and flyers — the direct route from print into the shop
• Outdoor advertising — banners and city lights with demonstrable effect
• Sponsor placements — a sponsor gets a number rather than an impression
• Vouchers and promotions — with their own discount tracking
• Print and business cards — event details without typing

Offline becomes measurable

QR codes turn offline marketing into a discipline with numbers, where only guesses were possible before. Anyone trying to optimise a budget, understand an audience and evaluate every channel will end up at trackable codes. And measurable, eventually, becomes profitable.
