Your iPhone will open your front door
Your quick mental checklist of "phones, keys, wallet" before leaving the house could soon be narrowed down to "phone, wallet." That's because Apple may be introducing a new function that would allow you to unlock your car and house doors with your iPhone.
It's all down to new tech in the near field communication chip in your iPhone, that's the thing responsible for easy transactions behind things like Apple Pay (jokes - we'll keep waiting for that in Oman). Apple has been working on this since 2014 and will be included in the upcoming release of iOS 12, which will be announced during the 2018 Worldwide Developers Conference (WWDC).
