NFC enabled car for access and start

 

Car access:

 The user is positioning the NFC phone/card close to the door handle, the car is interrogating the NFC phone/card and if and open the car if it matches

Start:

 When in the car, the user put the NFC phone/card in a dedicated slot and pressed the “start” button, the engine is started if correct NFC phone/card is recognized HF UHF LF
