# Connecting to the Internet

The card readers do not support offline functionality. To process transactions, your terminal must be connected to the internet.

The connection can be established via [Wi-Fi](#connecting-the-terminal-via-wi-fi) or the [mobile network](#connecting-the-terminal-via-mobile-network).

## Connecting via Wi-Fi

To use your POS terminal optimally, it should be connected to a Wi-Fi network. To do this, please follow these steps:

1. Open the quick access menu by swiping down from the top of the screen twice.
2. Tap the Wi-Fi icon in the top left corner, which will display all available networks.
3. Tap the network you want to connect your terminal to.

{% hint style="info" %}
If the desired network is not displayed, navigate to **Additional Settings > Add Network** and enter the connection details manually.
{% endhint %}

## Connecting via mobile network

Since your card reader contains a SIM card, you can also use it without a Wi-Fi connection. To do this, please follow these steps:

1. Open the quick access menu by swiping down from the top of the screen twice.
2. Tap the triangle icon in the middle at the top.
3. Enable or disable access to the mobile network by toggling the switch.

{% hint style="info" %}
Tap "Additional Settings" to view statistics on mobile data usage and more information.
{% endhint %}
