Square's Cash App is a peer-to-peer payment app that allows you to send and receive money with friends and family, without any requirement of cash on hand. Cash App is the most secure payment gate away. When someone sends you money on the Cash App, then it is a virtual currency and stays in the app. If you have an activated Cash App Card, you can use it as a debit card and spend your balance anywhere that accepts Visa. The Cash app direct deposit feature was recently added to make its deposit .
