# Setting up WiFi-based check-in using RADIUS servers

To allow your customers to [check in](/platform/day-to-day/operations/check-in.md) using Wi-Fi, you must first enable this feature in your location's settings.

{% hint style="info" %}
A Radius server license for specific Wifi routers incurs a charge of $/£/€6 per Access Point per month. Mikrotik can be integrated for free.
{% endhint %}

### What do I need?

Before you configure the controller, you need a RADIUS Server licence. You can contact <support@nexudus.com> to receive a licence.

{% hint style="info" %}
Each license comes with two geographically redundant servers for RADIUS Authentication and RADIUS Accounting. We create these as close as possible to your physical location based on the data centres we have available.
{% endhint %}

When you have the license, copy and paste it in **Settings** > **Integrations** > **Managed RADIUS servers**. Then, click **Save changes**.
