Cash App is a mobile peer-to-peer money transfer service that allows users to easily send and receive money from family and friends. A Cash App Card is a Visa debit card issued by Cash App, which you can use to access the funds inside your Cash App account. Rather than transferring the money from Cash App to a traditional bank, this card allows you to directly spend your Cash App funds at retailers (online and traditional), and withdraw funds from ATMs. Your Cash App Card is reloadable so Cash App can also serve as your primary bank. This is a decent option for those with a negative checking account history who have problems qualifying for a checking account at a traditional bank.
