QR Codes for Events: The Complete Guide (2026)

Frequently asked questions

How do QR codes work for events?

A QR code encodes your event page URL. Guests point their phone camera at it — on a poster, flyer, screen, or chat message — and open your event page instantly, where they can register, RSVP, or buy a ticket.

How do I get a QR code for my event?

Create your event on Event Flo and click Download QR in the event editor. You get a free, high-resolution code that links to your public event page — no separate QR generator or paid tool needed.

What are the main ways to use QR codes at events?

Four: promotion (posters, flyers, and WhatsApp forwards that link to your event page), registration (guests sign up by scanning), RSVP invitations, and door entry (each ticket carries a unique QR code that staff scan at the door).

Are event QR codes free?

On Event Flo, yes — generating an event QR code, collecting registrations, and scanning tickets at the door are all free. There are no platform fees, so hosts keep 100% of paid ticket revenue.

What size should a QR code be on a poster?

At least 2 x 2 cm on handheld flyers. For posters, follow the 10:1 rule — a code scanned from 1 metre away should be about 10 cm wide. Keep a white margin around the code and always test-scan a real print before mass-printing.
