# POS (Point Of Sales)
The app is also available on the POS system. Once installed, it will be visible on the POS app and the order completion screen.
With the new version of the POS, the app needs to be added before use. It is available in the Shopify admin.
1. From your Shopify admin, go to **Sales channels** > [**Point of Sale**](https://admin.shopify.com/apps/point-of-sale-channel).
2. Navigate to **Settings** > [**POS apps**](https://admin.shopify.com/settings/apps/point-of-sale-channel/settings/pos-ui-extensions).
3. Select **Serial Numbers** by My Product Cares.
4. In the **Additional areas** section, click **Add**.
## Order completion
On the available tiles, scroll to the right or left to find the **My Product Cares/Registration** app.
Once the app is open, you can enter the serial number for each item in the order. You can either enter the serial numbers manually or use a scanner for faster input.
