QR codes help at every stage of an event: on the invitation to add it to calendars, at the venue for the schedule, map and Wi-Fi, and afterwards for slides, photos and feedback. Make the main code dynamic and one printed code can follow the whole event, switching to next year’s page when it’s over. QRfinity’s codes are free and never expire.
Which QR codes does an event need?
| Stage | Code | What it opens |
|---|---|---|
| Before | Event | Adds the date, time and place to the phone’s calendar |
| Before | Dynamic link | The event page: agenda, speakers, registration |
| At the venue | Location | The venue in Google Maps, with directions one tap away |
| At the venue | Wi-Fi | Joins the event network without typing |
| At the venue | Dynamic link | Today’s schedule, which you can update as sessions move |
| After | Dynamic link | Slides, recordings, photos or a feedback form |
One code for before, during and after
Badges, banners and printed programmes are expensive to redo. A dynamic code holds a short link you control, so the same print can do three jobs:
- Before: point it at the registration and agenda page.
- During: point it at the live schedule when doors open.
- After: point it at the slides, photos or feedback form, and later at next year’s event.
Change the destination yourself from your dashboard at any time, or let a date limit do it for you at the moment the event ends.
For extras only attendees should see, such as recordings or a photo gallery, add a password to the code and share it from the stage. See password-protected QR codes.
Where to put codes, and how big
- Badges and lanyards: 3 to 4 cm wide, on the front.
- Banners and stage screens: about one tenth of the distance from the audience: 1 metre wide for a room where people sit 10 metres away.
- Tables and programmes: at least 2 cm wide, with a clear margin.
- Test at the venue. Lighting, glossy finishes and screens behave differently in a dark hall. Scan from the back row before doors open.
The print size guide has the full rule.
How many people scanned?
Every dynamic code shows total and unique scans, the hours people scanned, devices and countries. Use one code per placement, such as the badge, the banner and the programme, to see which ones people actually used. We don’t store anyone’s IP address.
What does it cost?
Static and dynamic codes, scan analytics and PNG and JPG downloads are free, and codes never expire. Date and scan limits, passwords and the other advanced features are free on one code; plans from $5 a month cover more codes and add print-ready SVG, PDF and EPS files. See pricing.
