What is a one-sentence summary of the following article?
On a computer, "Wallet" is at the top of the screen. On the mobile phone app, "Wallet" is under the menu. Tap the button to navigate to the wallet. Your wallet is your list of debit cards, credit cards, and bank accounts associated with your PayPal account. You can link more than one. This button will bring up a page where you can choose what type of account you want to enter. Pick either "Link a Bank" or "Link a Debit Card," depending on your preferences. If you're not comfortable linking PayPal to your main checking account, you can set up a new, separate checking account with an online bank like Ally, Radius, Chime, or Aspiration. You will need the account information for whatever type of payment you decide to enter. PayPal needs this information to make payments for you.  For a bank account, you will need to choose checking or savings. Then enter both the routing number and the bank account number. For a debit card, you will need to enter the card number, the expiration date, and the security number. While debit cards are instantly confirmed, you will need to take a few extra steps to confirm a bank account. You can either confirm the account instantly by entering your bank ID and password, or you can do it manually by watching for small deposits PayPal will make into your account.  To do it instantly, enter your bank ID and password when prompted. PayPal doesn't store this information. To do it manually, watch for the deposits in your bank account over the next couple of days. They will be very small. Then, go back to the bank account screen on your PayPal account and enter the amount PayPal sent you in 2 separate deposits. Don't get too excited! These amounts are less than $1 USD, and PayPal withdraws them after a few days.

Summary:
Click on "Wallet" in your account. Select the "Link a Card or Bank" button. Follow the prompts to add the appropriate information. Confirm your account if you're using a bank account.
