Soon BMW owners may be able to use their car's electronic key to do more than just open doors and start the engine.
Thanks to Near Frequency Communications (NFC), a BMW key could be used like a credit card to pay for purchases and maybe even access card lock doors.
But the technology could go even further by linking the key to the vehicle’s navigation system. This would allow the driver to buy tickets or make reservations through the vehicle’s navigation system and because the key is integrated into the car, paying for or verifying that purchase would be as simple presenting your BMW key upon arrival. Even your electronic proximity key for a hotel stay could be integrated into the electronic BMW key. BMW’s electronic key already holds some vehicle information on it so paying for maintenance or repairs is another obvious application.
