# Hardware moderators

Hardware moderators are **objects that allow you to log in to our** [**scan devices**](/event/hardware/scan-app-devices.md). 

You create a new moderator, limit the permissions it has and download the **created QR code**. This QR code can be scanned when starting up a scanner which **logs you in on the device**.

These have multiple permission settings:

* **Scanning** between zones
* **Give** food or beverages
* **Check in** vehicle into parking zones
* **Multi parking validation** to verify if a vehicle has access to at least one selected parking zone
* **Checkout** of the event
* **Get information** about a QR code or NFC tag

{% hint style="info" %}
If you like, you can fine-grain these permissions. 

*E.g. I would like this QR code to only scan people into zone B and nothing else.*
{% endhint %}

### Download QR code PDFs in bulk

The index of the hardware moderators gives you the ability to **multi-select moderators**. Once you selected at least one, a new button is shown to bulk download the login QR codes in PDF form:

<div align="left"><figure><img src="/files/hxTRhcZOIi8A2anESG8K" alt="" width="194"><figcaption></figcaption></figure></div>

After clicking this button you are presented with a **text area** where you can **add information** that should be **printed on those PDF**s.

{% hint style="info" %}
This text area supports [formatting](/event/misc/text-formatting.md).
{% endhint %}

{% hint style="info" %}
Many events make use of this 'description' area for showing the following information:

* *What do do when somebody scans red (for example: can not enter today)?*
* *A phone number to call when you have issues or questions*
* *What to do with the scanner after the party ends?*
  {% endhint %}

{% hint style="warning" %}
Only available for events that use our scan devices
{% endhint %}
