How to add money to Apple Cash

After you set up Apple Cash, you can add money to your balance using the debit or prepaid cards that you already use with Apple Pay in Wallet. If you don’t already have one of these cards in Wallet, you need to add one before you can add money.

1. Go to your card info:

•iPhone: Open the Wallet app, tap your Apple Cash card, tap the More button , then tap Add Money.

•iPad: Open the Settings app, tap Wallet & Apple Pay, tap your Apple Cash card, then tap Add Money.

•Apple Watch: Open the Wallet app, tap your Apple Cash card, tap Card Balance, then tap Add Money.

2. Enter an amount. The minimum is $10.

3. Tap Add, then confirm the U.S. debit or prepaid card2 that you want to use to add money, and confirm the correct billing address. To use a different debit or prepaid card, tap the arrow  next to your card, then choose a card.

4. Confirm with Face ID, Touch ID, or passcode.

To make sure that your balance is updating, you need a cellular or Wi-Fi connection.
