How to update an event poster without reprinting?
Events, concerts, fairs, talks and festivals have details that change: ticket prices, time, capacity, speaker. With a dynamic QR the printed poster stays valid until event day, no reprints.

Why reprint posters when only one detail changes?
Reprinting event posters costs between 50€ and 300€ depending on format. A date or venue change forces you to discard the entire print run.
Reprinting 200 A3 posters costs between 90€ and 180€ and requires re-pasting them in bars, streets and partner venues. If only the schedule or one ticket type changes, it's not worth it.
Dynamic QR pointing to an updatable event landing
A dynamic QR on the poster points to an updatable landing page. You change the date, venue or link from the dashboard without touching the printed poster.
The poster carries a dynamic QR pointing to an updatable landing page. When capacity changes or a ticket sells out, edit the destination or the landing itself. The printed QR stays untouched.
§HOW IT WORKS
How do I set it up for my event?
Create the event landing, generate the dynamic QR on codigo-qr.es pointing to it, print it on the poster and update the landing whenever something changes.
01
Create an event landing (your site, Linktree, public Notion or template).
02
Generate a dynamic QR pointing to that landing.
03
Design the poster with the QR clearly visible (minimum 3×3 cm for A3).
04
When event details change, edit the landing or change the QR destination.
§BENEFITS
Benefits for promoters
Event promoters with dynamic QR on posters eliminate reprint costs from changes and get analytics on how many people scan each poster.
- A single poster works through the entire event promotion period.
- Schedule or capacity changes reflect instantly for every scan.
- Per-day scan analytics tells you if the campaign is working.
- Lets you redirect to ticket sales or streaming depending on the moment.
- Reduces reprints and paper poster waste.
§FAQ
Frequently asked questions about the event poster QR
A dynamic QR on an event poster stores the destination URL on a server. You change the destination from the dashboard without reprinting a single poster.
Yes. The dynamic QR stores the destination URL on our server, not in the physical code. From the dashboard you change the destination in seconds and the next scan goes to the new URL. Already-posted posters keep working.
For an A3 poster (29.7 x 42 cm) the QR should be at least 3 x 3 cm. Below that, mobile readers struggle from a distance. We recommend 5 x 5 cm so it scans reliably from 50 cm away.
Yes. If the event moves online or adds a stream, change the QR destination to the streaming room (YouTube Live, Zoom, Meet). Anyone scanning the poster will land on the live stream.
