Utilizing the NFC-tag (Near Field Communication) technology built into most modern smartphone batteries, the Hyundai i-30 hatchback-based "Connectivity Concept" allows users to open car doors with just a swipe of their mobile phones, essentially turning the smartphone into the most high-tech car key we've ever seen. The phone's technology is further integrated with the car once inside by docking in the center console and activating a user profile, allowing full control of the smartphone via a dash-mounted touch-screen display.
