# Offline Scanning Mode in SimpleTix Organizer App

> Use Offline Scanning Mode in the SimpleTix Organizer app to continue scanning tickets when internet connectivity is unreliable or unavailable.

<Info>
  **Backup Solution for Poor Connectivity**: Offline Scanning Mode is designed as a failover solution for situations with unreliable internet. For optimal real-time validation, use standard scanning modes whenever you have stable network connectivity.
</Info>

# Offline Scanning Mode

Offline Scanning Mode provides a reliable backup option for scanning tickets when you have unstable or non-existent internet connectivity. This feature uses a locally stored backup of your event's ticket data to validate scans, allowing you to continue checking in attendees without interruption.

## How Offline Scanning Works

<Steps>
  <Step title="Automatic Local Data Sync">
    The app automatically syncs your event's ticket data every three minutes when it's open and connected to the internet, storing this information locally on your device
  </Step>

  <Step title="Access Offline Mode">
    When experiencing network issues, tap **Scan Offline** at the top of the "Admit" screen, right next to "Scan Anything"
  </Step>

  <Step title="Scan Using Local Data">
    The app validates scans using the locally stored backup data, displaying a timestamp showing when the last successful sync occurred
  </Step>
</Steps>

<Warning>
  Offline Scanning Mode is enabled by default in the app's settings and does not require additional setup.
</Warning>

## When to Use Offline Scanning Mode

Use Offline Scanning Mode specifically for:

* **Poor internet connectivity** at your venue
* **No internet connection** available
* **Network outages** during your event
* **Backup validation** when primary connectivity fails

<Tip>
  For the most reliable and real-time ticket validation, we strongly recommend using the standard "Scan Anything" mode or event-specific admission options whenever you have stable network connectivity.
</Tip>

## Important Limitations

Due to the offline nature of this feature, be aware of these potential issues:

<Warning title="Data Sync Limitations">
  **Recently Sold Tickets**: Tickets sold after the last data sync will not be in the local backup and will not scan as valid in Offline Mode.

  **Cross-Device Admissions**: If another device has admitted a ticket after the last data sync, that information won't be reflected on your device, potentially allowing duplicate scans.
</Warning>

### Features Not Available in Offline Mode

The following features require an internet connection and are not supported in Offline Mode:

* **Waivers**: Waiver processing requires online connectivity
* **Attendee Photos**: Photo capture and validation needs network access
* **Square Product Redemption**: Product sales require real-time processing

## Best Practices for Offline Scanning

<Steps>
  <Step title="Ensure Recent Sync">
    Keep the app open with internet connectivity for at least 5 minutes before your event to ensure the most recent ticket data is synced locally
  </Step>

  <Step title="Monitor Sync Status">
    Check the last sync timestamp displayed during offline scanning to understand how current your local data is
  </Step>

  <Step title="Return Online When Possible">
    Switch back to standard scanning modes as soon as network connectivity is restored to ensure real-time validation
  </Step>

  <Step title="Coordinate Between Devices">
    If using multiple devices, establish communication protocols between scanning stations to minimize duplicate admissions
