> **Info**
>
> Other **Terminal configuration** settings as well as [peripheral till device settings](/help/store-management/device-config) may also be relevant for your SCO tills, depending on the functionality that you require. Ask your Fiftytwo consultant if you're in doubt.

## Look, feel, and customer functionality

You define customer-facing functionality as well as the look and feel and the required languages of your SCO tills in [ViKING POS Designer](/help/pos-designer/wpud).

It has a template for SCOs that you or your Fiftytwo consultant can customize to suit your organization's needs.

> **Tip**
>
> If you want to know what it feels like for customers to use an SCO, and for shop assistants who may occasionally need to help out customers at the SCO, see [ViKING POS self-service checkouts (SCOs)](/help/pos/sco).

## Random checks

If you want to perform random checks of customers' purchases to verify that they've scanned or selected all their articles, use the **Customer survey** feature. You can't currently set up the customer survey feature in ViKING Store Management, but you or your Fiftytwo consultant can do it in the VB021 mask in ViKING Client. Ask your Fiftytwo consultant if you're in doubt..

The customer survey feature is typically used for postcode surveys, but because you can configure its frequency to be random, it's also ideal for random checks of customers' purchases.

> **Info**
>
> If you use the customer survey feature for random checks of customers' purchases, you can't also use it for asking for customers' postcodes or other survey questions.
