Methods for establishing continuous communications between a vehicle and a mobile device using Near Field Communications (NFC), and using the NFC communication to enable application hosting on the mobile device and other features. An NFC-enabled mobile device is placed in close proximity to an NFC antenna in the vehicle, where in one embodiment the NFC antenna is integrated into a wireless charging pad for the device. Continuous wireless NFC communications are established between the mobile device and the vehicle, such that the device can serve as a controller for in-vehicle systems. Control applications on the mobile device can include driver-commanded features such as operation of windows and door locks, as well as automatic features such as navigation and collision warning. Other uses of the NFC-enabled mobile device are also disclosed, such as event-based information capture and gesture-based control.
