Next, you'll be prompted to position your card in the frame to scan it. Alternatively, you can select Enter Card Details Manually to enter your card information and edit your settings, like choosing a default payment card. Apple will then make contact with the card issuer to verify your payment information is valid, and you'll be ready to use Apple Pay once this step is completed. It typically takes no more than a few minutes to verify your information with your bank or card issuer.

Tap on the button with a plus sign to add a card to your Apple Wallet and follow the prompts.

How to use Apple Pay on your Apple Watch

The days of "I forgot my wallet" are long gone. Once you add a card to your Apple Wallet, you enable Apple Pay on your iPhone.

2. Tap on Add Card.
3. Choose Previous Cards to add any payment cards previously linked to your iPhone and you'll be prompted to enter the security code for each, or

Apple Pay works by ensuring your credit or debit card number and information is encrypted and never shared with the merchant when you check out. A new code is created each time you pay somewhere that accepts Apple Pay, making your financial data safer from being cloned or stolen.
