Thank you, Jim, for your detailed explanation of how Apple Pay works. Now I feel even better about using it. As you said, whether or not to use it is a personal decision, but it's nice to know it isn't adding to a digital profile more than using a physical credit card would.

Apple can’t decrypt it, but will add it to the Secure Element within your device. The Secure Element is an industry-standard, certified chip designed to store your payment information safely. The Device Account Number in the Secure Element is unique to your device and to each credit or debit card added. It’s isolated from iOS and watchOS, never stored on Apple Pay servers, and never backed up to iCloud. Because this number is unique and different from usual credit or debit card numbers, your bank can prevent its use on a magnetic stripe card, over the phone, or on websites.

This information is sent along with additional information needed to complete the transaction to the store’s point of sale terminal. Neither Apple nor your device sends your credit or debit card number. Before they approve the payment, your bank or payment network can verify your payment information by checking the dynamic security code to make sure it’s unique and that it’s tied to your device.
