Shopify POS is a point of sale app that enables users to sell products in person. Users can create a cart for each customer, customize the cart in several ways, and then accept payment with a wide range of payment methods. ## Integrate with Shopify POS There are multiple options available that enable you to customize the Shopify POS app. The following list introduces the available technologies that you can use to extend the capabilities of Shopify POS. - **[POS UI Extensions](/docs/api/pos-ui-extensions)**: Use POS UI Extensions to extend the functionality of the Shopify POS app at defined extension points. With the extension API, components, and tools, developers can build a custom merchant experience in the Shopify POS app with a native look and feel. - **[Embedded POS Applications](/docs/apps/build/pos/embed-app-in-pos)**: Extend your Shopify app directly into Shopify POS. ## Legacy POS Extensions > Caution: > On February 28, 2025, developers and merchants will no longer be able to view or access product recommendation, cart app, or POS link extensions in Shopify POS. > We recommend building with [POS UI extensions](/docs/api/pos-ui-extensions) instead.
