Is using Apple Pay secure?

Yes. Security and privacy are at the core of Apple Pay. When you add a credit or debit card to Apple Pay, the actual card numbers are not stored on the device or on Apple servers. Instead, a unique Device Account Number is assigned, encrypted, and securely stored in the Secure Element on your device. Each transaction is authorized with a one-time, unique, dynamic security code, instead of using the security code from the back of your card.
