The Cash app currently works with a number of banks and you can link a bank account instead of a Cash App debit card. The app works with the Lincoln Savings Bank, Bank of America, USAA, Sutton Bank, Citi, BB&T, US Bank, Capital One, Chime, PNC, Regions, TS Bank etc. It also depends on the user account, and I would recommend contacting Cash App customer service with your $Cashtag and email address to get an updated list of compatible banks for your account.
