Compatibility and Network Requirements To take full advantage of this technology, you need an iPhone model that supports NFC, typically the iPhone 6 or later, though specific features vary by model.

Adding Cards to Apple Wallet Getting started is straightforward through the Wallet app. You can configure the iPhone to use either Touch ID, which reads your fingerprint, or Face ID, which maps your face with infrared technology.
While the card itself does not need to be physically present, some transactions might require a stable connection depending on your bank’s security protocols. When you make a purchase, the transaction is processed using a dynamic security code generated for that specific sale, meaning your real card details are never shared with the merchant or exposed during transmission.
