What is nfc iphone?

NFC (Near Field Communication) on iPhones is a feature that allows users to share data with other devices or make contactless payments using their phone. NFC is available on iPhones 7 and newer models, and can be used to transfer data such as photos, contacts, and documents between iPhones or other devices that support NFC. It can also be used for payments through Apple Pay by holding the phone near an NFC reader at a store. NFC can be enabled on iPhones through the settings menu, and users need to authenticate payments with Touch ID or Face ID.
