Is Apple Pay secure?

Yes, Apple Pay ®is secure.

• Every transaction on an Apple device requires you to authenticate yourself with either Face ID, Touch ID or device passcode.
• Each time you make a purchase, Apple Pay uses a number specific to your device and unique transaction reference. Your full card number is never stored on your Apple Device and it can't be shared with merchants.
• Do not enable others, including family members, to have their fingerprint registered on your device, or share your passcode, while you have a card registered in Apple Pay.
