Once uploaded:

  • The document is immediately added to the connected project.

  • AI automatically renames the file.

  • If the file matches an existing task, it is attached to that task.

  • If no matching task is found, the file will remain unassigned in the project.

Security & Privacy

  • Access is limited to Truss users.

  • The app is not available to clients.

  • Scanned documents are not saved locally on your device; they are uploaded directly to Truss.

  • QR codes expire after two minutes and are automatically refreshed to protect project access.

Troubleshooting

The QR code isn’t working or has expired

  • Refresh the Mobile Upload page to generate a new QR code.

  • Make sure you scan it within two minutes.

The app doesn’t open when I scan the QR code with my camera

  • Confirm you tapped the link that appears after scanning.

  • Truss Scanner is installed on your device.

My document isn’t attached to the right task

  • Check the project’s unassigned documents section.

  • Manually move the file to the correct task if AI didn’t find a match.

Issue with uploading files

  • If there’s an error uploading the file, an alert will appear in the bottom-right of the upload page and you’ll be able to retry the upload.

  • If that still doesn’t work, try logging out of the project or restarting the app.
