From here onwards, keitai or Japanese phones can boast of having not only FeliCa cards using RFID technology, but a built-in intelligent key as well. According to recent news, Sharp has embedded Nissan's "Intelligent Key" technology into a new cell phone to be released by Japanese telco NTT DoCoMo.

The Intelligent Key technology is equipped into 950,000 Nissan cars released since 2002. It's a two-way wireless communications system that's used so the car automatically unlocks the doors when the key comes into range. It also lets drivers start (or stop) the engine even without inserting the key in, as long as the key is inside the car. In this case, the key takes the form of a cell phone. The new Sharp cell phone b y DoCoMo embedded with Nissan's Intelligent Key (the first of its kind in the world) will be showcased on CEATEC Japan 2008 beginning September 30.
