You can use a credit card or debit card in Cash App, or you can link directly to a bank account. Here's how to do all of the above.

Link a bank account, debit card, or credit card, including Visa, MasterCard, Discover, and American Express. You can also link your PayPal account, which may be particularly useful.

Cash App prefers you link a debit card to facilitate instant fund transfers, but you can also choose to link up your bank account instead or as an additional option.

Although it's not technically a bank, it works like one because you can get a debit card and an account number. Cash App can also be used to invest in stocks and Bitcoin.

Through Cash App, users can send and receive money, get a debit card and receive direct deposits. The investing feature lets users invest in stocks for as little as $1.
