The Information reports that Apple is set to upgrade iPhones that are equipped with NFC chips with the ability to unlock doors, hotel rooms, and cars.

The NFC (near-field communication) chip, present in the iPhone 6 and up, allows for contactless information exchanges, and makes it possible to use Apple Pay to pay for purchases at stores by holding your phone close to a supported credit card reader. Apple is expanding its capabilities so it can interact with smart locks, building security systems, vehicles, and even mass transit payment facilities.
