How do I use Apple Pay on iPhone?

What Is Apple Pay?

Apple Pay is a digital wallet feature built into iPhone that securely stores your credit, debit, and prepaid cards. It uses near-field communication (NFC) technology for contactless in-store payments, and tokenization for online and in-app purchases. Apple never shares your actual card number; instead, it assigns a unique Device Account Number stored securely in the Secure Element on your device.
