Customers can use Cash App Pay at the Merchant’s physical locations or during ecommerce checkouts using a Laptop or Desktop computer. The customer linking process consists of three-steps as follows:

1. The Customer chooses **Cash App Pay** as their payment method at checkout (on the Merchant’s POS (Point-of-Sale) device or Customer’s desktop/laptop)

   <Note>
      POS devices can be tablets or desktop devices
