Near-field communication (NFC) is a set of communication protocols for communication between two electronic devices over a distance of 4 cm (1½ in) or less.[1] NFC offers a low-speed connection with simple setup that can be used to bootstrapping more-capable wireless connections.[2]
Usage[]
NFC devices can act as electronic identity documents and keycards.[2] They are used in contactless payment systems and allow mobile payment, replacing or supplementing systems such as credit cards and electronic ticket smart cards. This is sometimes called NFC/CTLS or CTLS NFC, with contactless abbreviated CTLS. NFC can be used for sharing small files such as contacts, and bootstrapping fast connections to share larger media such as photos, videos, and other files.[3]
NFC in Apple devices[]
NFC was first adopted by the iPhone 6 and 6 Plus for use with Apple Pay. The iPhone 7 and 7 Plus with iOS 11 added support for reading NFC tags.[4] AirTags use NFC to be identified by iPhones and 3rd-party devices when in lost mode.[5]
