iOS 12 to Allow iPhones to Unlock Doors Via NFC
The change to the near-field communication, or NFC, chip, which is expected to be announced next month, could pave the way for people to use iPhones for other security-sensitive interactions, from paying transit fares and opening car doors to verifying their identity in other ways.The Information reported nearly four years ago that Apple was looking to expand NFC capabilities to building security and transit ticketing, working with its campus security vendor HID Global on the technology.
Already, employees at Apple’s new campus in Cupertino, Calif., are using their iPhones to gain access to buildings and offices, suggesting that the technology has been deployed there, people familiar with the matter said.
Today's report notes that while Bluetooth is already used to manage some smart locks using iPhones, NFC offers a more secure method for connections and authentication, an important consideration for companies and government agencies in particular.
