In order to verify that payment method follow the steps below so you can make purchases again.

"How to verify your identity for Apple Cash

1. Go to your card info:

• iPhone: Open the Wallet app, tap your Apple Cash card, tap the More button , then tap Card Details .
• iPad: Open the Settings app, tap Wallet & Apple Pay, then tap your Apple Cash card.
• Apple Watch: Open the Apple Watch app on your iPhone, tap Wallet & Apple Pay, then tap your Apple Cash card.

2. Tap Verify Identity.

3. Follow the onscreen steps. When capturing your driver license or state ID card, use these tips:

• Place your card on a dark background.
• Capture all four corners of your card.
• Make sure that there's nothing between your device's camera and the card that would obscure it.

The first time that you verify your identity, you might be asked for this information:

• Your full name
• Your Social Security number
• Your date of birth
• Your home address2
• Answers to questions regarding your personal history
• An image of your valid driver license or state ID card

To use all the features of Apple Cash3 you must verify your identity.

If you enter the wrong information, try to verify your identity again. If you don't see the option to verify your identity, contact Apple Support."
