# User passes

Add passes to users so they can identify themselves at Readers and get through doors you’ve allowed them access to. There are four types of passes:

* Mobile passes
* NFC cards
* CSN cards (any card with a serial number)
* PINs

{% hint style="info" %}
You can add passes before creating any access schedules
{% endhint %}

### Mobile passes

Users can create a mobile pass by downloading Accessia app on their device and logging in. When a user is created, they receive a welcome email asking them to do so

{% hint style="info" %}
Users must give Accessia app permission to access the device’s Bluetooth, location, and background location to use Accessia app as a pass
{% endhint %}

### NFC cards

{% hint style="info" %}
Adding a NFC pass requires a NFC card writer
{% endhint %}

Add an NFC pass to a user from the **user’s profile**

1. Go to the **Passes** tab
2. Click ‘Add NFC card’ in the upper right corner
3. Select the port with your NFC card writer
4. Place the NFC card on the card writer and wait till the card has been added to the user
5. Click close

{% hint style="info" %}

{% endhint %}

{% endhint %}

Add PINs to a user from the **user’s profile**

1. Go to the **Passes** tab
2. Click ‘Add PIN’ in the upper right corner
