The QR code-based Light Show dramatically reduces friction for fan participation. With app-based approaches, you need to communicate in the week leading up to the match asking fans to download a specific app, then worry about how many actually follow through. Fans may be hesitant to download an unfamiliar app, especially one that isn't their team's official app. With the QR code approach, there's no advance communication required — simply display the QR code one or two minutes before you're ready to start the Light Show, fans scan it with their phone cameras, and they're instantly participating. No app store, no downloads, no accounts to create. This simplicity translates to significantly higher participation rates because you've removed every barrier to entry.
