Digital keys are a new product of improved automotive technology. Car owners can use smart phones, electronic bracelets, electronic watches and other devices as car keys, which can unlock the car without a physical key, start the car, control the temperature inside the car, etc. NFC is a short-distance unlocking method for digital keys. NFC card swiping is responsible for entering the car from outside (when the phone is out of power), and NFC card swiping is responsible for starting the car inside.
