Merchants can use Shopify POS to sell in person with Shopify. Merchants can create a cart for each customer, customize the cart in several ways, and then accept payment with a wide range of payment methods. With App Bridge, you can extend or add new features to Shopify POS for both Android and iOS.
There are a few different ways to integrate with Shopify POS: full-screen apps, POS Links, and Cart Extensions. On legacy versions of POS, full-screen apps are available from the App Grid, accessed through the Apps button on the side navigation menu. On newer versions of POS, the Smart Grid is available for all apps, where all actions can be added to the grid and become tappable buttons.
