You'll need a Cash Card to add your Cash App account to Apple Pay. Here's how to do it in two different ways.

How Does Cash App Work? To use Cash App, you must first download the mobile app, available for iOS (4.7 stars out of 5) and Android (4.6 stars out of 5). You can also sign up for an account online.
