BMW Taught Cars To Open From A Discharged Smartphone

BMW has introduced the second generation of the smartphone-based central locking function for the vehicle. From now on, the digital key will work even when using a discharged gadget.

• The system still uses the NFC (Near Field Communication) protocol, but now it can be installed not only on smartphones, but also on smart watches. The main feature of the update was the emergence of a security chip that can read a digital key even from a switched off phone with a discharged battery.

• Starting the engine is possible if a device with NFC and a special application is placed, for example, on a wireless charging pad. In addition, BMW car owners can send the "key" to five people so that the car can be used, for example, by relatives or friends. The company did not provide a list of mobile devices that support the system.
• In the near future, the BMW digital key will be taught to work using the UWB 3.0 (Ultra-Wide Band) protocol. This will allow you to open the car and start the engine without taking your smartphone out of your pocket. Now the device with NFC must be brought to the doorknob.
