Recently, Xiaomi announced that it has officially joined the board of directors of the Car Connectivity Consortium (CCC), becoming the latest member of its board of directors and will promote the development and application of digital car keys.
It is understood that CCC is a global cross-industry organization dedicated to developing standards for smartphone-to-car connectivity solutions. Its member companies are more than 100, General Motors, BMW, Mercedes-Benz, Google, Apple, Samsung and others, all of which are members of the organization.
As smartphones are increasingly used in scenarios such as mobile payment, public transportation, and access control, car and mobile phone manufacturers are beginning to pay attention to the function of implementing digital car keys on smartphones. The digital car key allows the owner to use the mobile phone to unlock the vehicle, start the engine and other operations, and also support the key sharing with friends.
With the help of Bluetooth technology, smartphones are being used as alternative keys for your car. With the widespread connectivity of cars and smartphones, a new chapter in the history of car keys begins. In the future, microchips in smartphones will use Bluetooth technology to communicate with sensors installed in vehicles. This ensures that the smartphone is recognized as reliable as the fingerprint and that the car automatically opens when the driver approaches. If the battery runs out, you can still unlock the vehicle via NFC and lean your smartphone directly against the sensor.
Keyless access for Bluetooth technology
When the driver approaches, the digital car key allows the car to unlock automatically. In addition, only some doors can be unlocked and opened, while others remain closed. This offers great advantages, especially in the business sector.
For example, construction workers often come to the car in a very short time when loading and unloading goods. To ensure the safety of the device, they can program their smartphones with a digital key to automatically lock and unlock the vehicle.
Now that digital car keys have replaced traditional car keys, Lenz Technology has launched a car key solution that supports Apple's Find My function, which enables the location of car keys on the Find My app.
