Apple is making a significant change to a wireless chip in the iPhone that will allow users to more securely unlock doors enabled with the same technology, a person familiar with the matter said.
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.
