Yes. Comprehensive security measures apply to payment confirmations (authorisation) as well as data protection.
Apple Pay uses security features built-in to the hardware and software of your device to help protect your transactions. In addition, to use Apple Pay, you must have a passcode set on your device and, optionally, Face ID or Touch ID. You can use a simple passcode, or you can set a more complex passcode for even greater security.
Apple Pay is also designed to protect your personal information. Apple doesn’t store or have access to the original credit, debit, or prepaid card numbers that you use with Apple Pay. And when you use Apple Pay with credit, debit, or prepaid cards, Apple doesn't retain any transaction information that can be tied back to you—your transactions stay between you, the merchant or developer, and your bank or card issuer.
When you add a credit, debit or prepaid card to Apple Pay, information that you enter on your device is encrypted and sent to Apple servers. If you use the camera to enter the card information, the information is never saved on your device or photo library.
Apple decrypts the data, determines your card’s payment network, and re-encrypts the data with a key that only your payment network (or any providers authorised by your card issuer for provisioning and token services) can unlock.
