A QR code for event flyers and posters you can update after printing
You print 200 posters three weeks out. Then the opener changes, the ticket link moves to a different platform, or the show sells out and you'd rather send people to a waitlist. A normal QR code locks in whatever URL you gave it on print day — if that link goes stale, so does every poster on every wall.
A ScanTrail dynamic QR code encodes a permanent short link instead of the destination itself. You decide where that link points, and you can change it any time from your dashboard — after the posters are printed, after they're taped up around town, even mid-event. The code on the paper never changes; only where it leads does.
And because each code tracks its own scans, you can print a different code for each spot — the coffee shop corkboard, the campus union, the record store window — and see afterward which locations were actually worth the trip.

Change the ticket link after 200 posters are up
A ScanTrail code encodes a permanent short link; you control where it redirects. If the ticketing platform changes or the show sells out, update the destination once and every printed poster follows on the next scan. Nothing gets reprinted.
One code per location shows which posters earn their tape
Print a different dynamic code for each spot you poster. ScanTrail records scans per day and a time-of-day histogram for every code, so you can see that the venue-district posters got scanned on Friday nights while the campus ones did nothing. Next event, skip the dead spots.
SVG downloads that hold up at poster size
Download codes as SVG and they stay sharp whether you're printing a handbill or a full-size poster — no pixelated blocks. PNG is there for quick flyer layouts, and Pro adds custom QR colors so the code can match your poster art instead of fighting it.
Attendees scan with the camera they already have
No app to install — the phone camera handles it. Redirects are served from Cloudflare's edge network, so the link resolves fast whether the poster hangs on a quiet side street or outside a packed venue.
How to set it up
- Sign up free at forever-scan.com. The free plan includes 3 dynamic codes — enough for one event or three poster locations.
- Create a dynamic code and point it at your current ticket or event page.
- Download the code as SVG (best for large prints) or PNG and drop it into your flyer or poster design.
- Print and post. The code encodes a permanent short link, so the artwork never needs to change.
- When plans change, edit the destination from your dashboard. Every poster already on a wall redirects to the new page on its next scan.
Common questions
Can I change where the QR code points after the posters are printed?
Yes — that's the difference between a dynamic and a static code. A ScanTrail dynamic code encodes a permanent short link, and you set (and reset) its destination from your dashboard whenever you want. A static code bakes the URL into the pattern itself and can never be changed.
What happens to my codes if I stop paying?
If you cancel Pro, your account drops to the free plan, which keeps 3 dynamic codes working. Those codes keep redirecting, and you keep the last 7 days of analytics. A printed code doesn't go dead just because a subscription ended.
How much does ScanTrail cost?
The free plan includes unlimited static QR downloads (no account needed), 3 dynamic codes, and 7 days of analytics. Pro is $1/month or $10/year and adds 1,000 dynamic codes, full analytics history, custom QR colors, and CSV export. For a single event, free usually covers it.
How do I know which poster location a scan came from?
Create a separate dynamic code for each location — they can all point to the same ticket page. Each code reports its own scans per day, time of day, device, and country, so comparing locations is just comparing codes. The free plan covers 3 locations; Pro covers up to 1,000.
Do people need a special app to scan the code?
No. The built-in camera on iPhones and Android phones reads QR codes and opens the link directly. Redirects run on Cloudflare's edge network, so the page loads quickly wherever the poster hangs.
