# Add QR code overlays to your digital signage

### How QR overlays work

When you add a [QR code overlay](https://buzzblender.com/features/qr-code-for-digital-signage/) to an image or video, Buzzblender displays it on your screens alongside your content. Each scan redirects viewers to the URL you specify. The overlay stays visible while the content plays, giving customers time to notice and scan it.

### Before you start

* You need image or video content already uploaded to Buzzblender
* Decide where the QR code should link — this can be any public URL

### Set up a QR code overlay

1. **Upload your content.** Add the image or video you want to display to your playlist or content library.
2. **Add the QR overlay.** Apply a QR code overlay to your content item.
3. **Link to a URL.** Enter the destination URL for the QR code. Common choices include:
   * Product pages
   * Promotional campaign landing pages
   * Restaurant menus
   * Event registration forms
   * Feedback or survey forms
   * Mobile app download pages
4. **Publish to your screens.** Add the content with the QR overlay to a playlist and publish it to one or more screens.

### View scan analytics

Buzzblender automatically tracks QR code scans and displays the data in your admin dashboard. You can see total scans per playlist, which helps you understand which content drives the most engagement.

Use this data to:

* Compare campaign performance across different locations or times
* Identify which calls-to-action resonate with your audience
* Adjust your content strategy based on real engagement metrics

### Tips for effective QR overlays

* **Keep the destination mobile-friendly.** Most people scan with phones, so make sure the linked page loads quickly and is easy to navigate on a small screen.
* **Give viewers time to scan.** Place QR overlays on content that displays long enough for someone to pull out their phone and scan — typically 15 seconds or more.
* **Match the offer to the setting.** Link to content that makes sense for where the screen is located. A café menu QR code near the counter is more useful than a generic homepage link.
* **Test before you publish.** Scan the QR code yourself to verify it reaches the correct destination and that the page works as expected.
