Apple Wallet and Apple Pay are often confused, but they serve different purposes. Apple Wallet is an app on the iPhone that stores digital versions of things like credit and debit cards, insurance cards, boarding passes, and identification. Apple Pay, on the other hand, is a digital payment system that lets users make purchases in stores or online using the cards stored in Apple Wallet. When using Apple Pay, a unique number called a Device Account Number (DAN) is created for each card and stored in a secure chip inside the iPhone. This chip, called the Secure Element, is designed to keep sensitive information safe. When making a purchase, Apple sends the DAN along with a one-time security code to the merchant. This means the merchant never sees the user’s actual credit or debit card number, and Apple does not keep personal information linked to the transaction. To use Apple Pay, users must authenticate with Face ID, Touch ID, or a passcode. Apple Wallet also gives users access to the last four digits of a card’s Device Account Number. To view this information, users can open Apple Wallet, select a card, tap the three-dot button, choose "Card Details," and then tap "Card Information" after authenticating with Face ID. Apple Cash is a feature that works with Apple Pay, allowing users to send and request money through iMessage or using a Tap to Cash feature with the Apple Cash card in their Wallet. This feature requires the recipient to have an Apple device and be eligible for Apple Cash. If the recipient uses an Android device, a different service like Venmo would be needed. Users can add money to Apple Cash using a debit card, set up recurring payments, or transfer funds directly to their bank account.
