If someone told you that you could start your car without inserting a key in the ignition, what would you think? The Toyota Avalon uses an RFID (radio frequency identification) technology called NFC (near field communication) to send a signal from a so called smart key to an onboard sensor. Once the sensor picks up the radio signal, pushing an ignition switch gets the vehicle started.
The smart key also unlocks the car or the trunk. The same NFC technology is used for the Corvette and Cadillac XLR. Other automobile manufacturers including Renault, Mercedes and BMW are offering keyless cards to identify authorized drivers.
It’s not quick as slick technology as that used for letting a Lexus park itself between two towers of delicate champagne glasses, but interesting nonetheless.
