How a QR Code Event Wall Works

Three steps: create a wall, display the QR code, and content from guests appears live on your screen — no app downloads required.

Last updated: May 2026

Short answer: A QR code event wall lets event guests share photos and messages from their phones by scanning a QR code — no app download, no account creation. Submissions appear live on a projected screen or TV. Setup takes about 60 seconds: create an account, name your event, and display the auto-generated QR code at your venue. Free tier available; paid plans from $8.99/month unlock unlimited submissions, downloads, and custom branding.

Frequently asked questions

How long does it take to set up a QR Wall?

About 60 seconds. Sign up with email or Google, name your event, and the QR code generates automatically. You can customize the display theme later; the wall is functional immediately.

Do guests need to download an app?

No. Guests scan the QR code with their phone camera (iOS or Android, any device with a built-in camera). It opens a mobile-web submission form in their browser. No accounts, no downloads, no installs.

What kind of content can guests submit?

Photos, text messages, and emoji reactions. All submissions appear live on the host's display screen. Photos are processed and resized server-side; text is moderated by AI when enabled (Professional tier).

Where does the wall display?

Open the host's display URL on any device with a web browser and HDMI output — a laptop connected to a TV, a Chromecast, an Apple TV with AirPlay, or a dedicated event projector. Two display modes available: slideshow (rotating focus) and feed (grid of recent submissions).

Does QR Wall work without WiFi?

Both the host display and guests need an internet connection. Most event venues provide WiFi; guests can fall back to mobile data on cellular. The submission flow uses standard HTTPS — no special network configuration required.

Is content moderated?

Yes — AI moderation is available on the Professional tier ($14.99/month) and screens both text and images using OpenAI's omni-moderation model across multiple languages. All tiers also support manual approval queues and keyword filters.
