Cell phones are becoming intelligent keys

In an attempt to free space in the pants, Nissan, Sharp and Japanese phone company NTT DoCoMo are arrived at the idea that Smart touch keys, or smart keys for phones. Nissan since 2002. this year, offers customers the chance while Sharp should soon design a mobile phone that would run on NTT DoCoMo network.
It is enough to have one phone / key in the pants that would transmit a unique signal. When the owner of the devices went in his car, sensors would recognize the tone and unlock the door when you get lunch.
The same signal would be sufficient to prepare an engine, and that is enough to press the Start button. The three companies should introduce a new hybrid by the end of the month of October, of course, only to the Japanese area.
