Security Features: Apple Pay is designed with security in mind. When you add a 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, a dedicated chip in your device. Each transaction is authorized with a one-time unique dynamic security code.
