How QR code works for conferences
Snapr makes QR code for your conference simple and effortless. Create an event in seconds, get a unique QR code, and share it with your guests. They scan the code and upload photos directly — no app download needed.
The QR code holds one thing: the guest upload address for a single event — a snapr.no link with the event id and a 64-character access key. A phone camera opens it in the browser. Every event gets its own code, and it points at nothing else.
Everything is included in the free tier: up to 200 photos, live slideshow, QR code, and 14-day storage. Need more? Premium keeps the photos a full year, with original-quality downloads and unlimited uploads, for a one-time payment.
Setting up QR Code
- 1Open the QR tab in the event dashboard and scan the code with your own phone first — you should land on the upload page for your event, not an error.
- 2There is no PNG or SVG export yet: print the page straight from the browser (Cmd/Ctrl+P) or take a screenshot and drop it into your table cards, menu or sign at the size you need.
- 3Print on matte paper, keep at least 5 mm of white margin around the code, and never place it over a photo or a dark background — the scanner needs the contrast.
- 4Test it in the room, at the distance and light level guests will actually have: one card on a table, one sign by the entrance, both scanned from where people will stand.
QR Code — the specifics
- What the code contains
- A https://snapr.no/<language>/guest/<event-id> link plus a 64-character key — around 110 characters in total, unique per event.
- Error correction
- Level H in the dashboard (about 30% of the code can be damaged and still scan), level M on the big-screen overlay.
- Print size
- Table card: at least 4 × 4 cm. Sign read from 2 m: at least 20 cm. Rule of thumb — code width = scan distance ÷ 10.
- Size on the big screen
- 15% of screen width by default, placed in one of the four corners; toggled with Q or a click on the screen.
- How long it works
- As long as the event lives: 14 days on the free plan, 365 days on Premium. The key never changes, so a printed code stays valid the whole time — and cannot be revoked.
- Export as a file
- Not available yet — the download button says so. Print from the browser or screenshot the code; it is rendered as SVG, so it stays sharp when scaled up.
When something goes wrong
A guest points the camera at the code and nothing happens.
Older Android camera apps need QR scanning switched on in settings, and some guests are in a camera app that does not scan at all. Write the plain address under the code as a fallback so it can be typed in — it is long, but it works.
The code will not scan in the venue's low light.
Glossy card stock reflects candles and spotlights straight back into the lens. Reprint on matte paper, move the card away from the tea light, or send guests to the QR overlay on the big screen — that one is backlit and always readable.
The page opens but says the link is invalid.
The address lost its ?k=... part — usually because someone copied a shortened version, or the code was cropped in a design tool. Regenerate it from the QR tab and copy the whole thing.
What it is not good for
It is not access control: anyone who can photograph the code — including a guest who snaps it off the big screen and forwards it — can upload, and the key cannot be revoked, so don't use it where the guest list has to stay closed.

Related features
Built for the one evening where it has to just work.
Live Slideshow
A full-screen browser page at snapr.no/<language>/event/<event-id>/display that listens for new uploads and shows them as they arrive. It runs on whatever drives the screen — laptop, TV browser, Chromecast or AirPlay — and needs no software installed.
Photo Sharing
After scanning the QR code a guest lands on an upload page in the phone's browser: one button opens the camera, the other picks from the gallery, up to 20 files per go. The files join the event's shared collection and appear on the big screen.
Photo Wall
A photo wall is the grid mode of the display page: instead of one picture at a time, the screen tiles up to six guest photos at once in a fixed asymmetric layout, and the selection moves one photo forward on every interval as new uploads arrive.
TV Display
TV display means getting the event's display page onto the television at the venue. Three routes: an HDMI cable from a laptop, casting a Chrome tab to a Chromecast, or AirPlay screen mirroring. The TV runs an ordinary web page — there is no Snapr TV app.
Photo Booth Alternative
Using Snapr instead of renting a photo booth: guests shoot on their own phones, upload through a QR code, and the pictures appear on a screen in the room. There is no box, no camera, no lighting and no prints — only the live screen and the shared gallery.
Guest Upload
Guest upload is the core of Snapr: a guest points their phone camera at your QR code, the upload page opens in the browser, and they pick photos from the camera roll or shoot a new one. No app, no account, no password — the link itself is the access.
Frequently Asked Questions
What guests and hosts ask about most.
Can we collect photos across multiple sessions and speakers throughout a multi-day conference?
Yes. One QR code covers the whole conference, so photos from the keynote, the breakout sessions, and the networking breaks over several days all flow into the same live gallery instead of being scattered per session.
Is Snapr suitable for professional and networking-style photos, or is it just for party snapshots?
It's simply a shared photo gallery, so it works for whatever your attendees photograph — speakers on stage, panel discussions, or people connecting during breaks. There's no party theme built into it.
How does Snapr work for a conference with a large number of attendees?
Every attendee scans the same QR code from the program, badge, or slide, and uploads straight from their phone — no app, no registration. Photos display live on screens in the venue, and the free plan covers up to 200 photos, with Premium removing the limit entirely for larger events.
