I’m a bit of a futurist; I like to speculate about new technologies. And I’ve always though that eventually, all of your tech needs will be filled by one device, probably all merged into a phone. Already this has happened to the majority of eletro-fobs: your phone can also be your music player and your camera and your internet access. Eventually you’ll be able print full sized A4 paper from your phone via an extendable arm and you’ll be able to project high quality video onto a wall via a mini projector. Maybe eventually we’ll have credit card swipes or RFID readers in our phones that would help speed along business transactions.
Nissan’s developed a technology along those lines with Sharp and NTT DOCOMO that will allow you to lock and unlock your car via your phone. It seems pretty simple, just squeeze your key-fob into a phone. The phone apparently works on Nissan’s two-way communication Intelligent Key system and would allow you to not only lock and unlock the car door, but also start and stop the engine. Pretty cool. It should be available starting in 2009.
