# Checking in using Wi-Fi
Allowing customers to check in using your wifi network.
If you want your customers to [check in](/platform/day-to-day/operations/check-in.md) using Wi-Fi, you must first enable this feature in your space's settings and then set up access tokens to provide internet access. You can also use [passes](/platform/day-to-day/inventory/passes.md), which you can sell to a customer directly or through a [plan](/platform/day-to-day/inventory/managing-plans/about-plans.md).
To use Wi-Fi check in, you must install a router that supports MikroTik (MT) or RADIUS devices.
## To enable Network check-in
1. If the side menu is not visible, click.
2. In the side menu, click[ **Settings**](https://platform.nexudus.com/settings).
3. In the **Features** section, click [**Check-In system**](https://platform.nexudus.com/settings/checkin).
4. Under **Network Check-in**, select **Yes** to enable MAC-based check-in for users.
5. **Optional**: Set the maximum number of devices per user.
6. Click **Save changes**.
After a customer adds their device, Nexudus Spaces recognises the device every time the customer accesses the network. The customer must also have a valid pass or access token. When the customer becomes inactive for 15 minutes, they are automatically checked out.
## About Access Tokens
With **Access Tokens**, \_\*\*\_you can give a customer a block of minutes that they can use to connect to the internet. Access Tokens are directly linked to Check-In via Wi-Fi, so that when someone is connected via the captive portal, they can use the token to access the internet. Access tokens simply provide internet access for a certain time period.
### To add an Access Token
1. If the side menu is not visible, click.
2. In the side menu, click [**Operations**](https://platform.nexudus.com/operations).
3. In the **Access & Check-in** section, click [**WiFi Access Tokens**](https://platform.nexudus.com/operations/accesstokens).

6. From the **Location** drop-down list, select one of your spaces.
7. In the **Description** textbox, type the details about your token.
8. In the **Minutes included** textbox, type how many minutes are available for your token.
9. **Optional**: If you want to limit the validity period of your token, select the date range in **Valid from** and **Valid to**. If you leave these fields blank, your token is valid until its minutes are depleted.
10. In the **User limit** textbox, type the maximum number of users who can be assigned to your token.
