How does the BMW iVision use digital keys?

I'm interested in the digital key feature of the BMW iVision. Can you explain how it works and if it is secure to use?

The BMW iVision uses a combination of NFC technology and the BMW Connected App to provide a secure and convenient way to access your car. It works by creating a unique digital key on your smartphone that uses Near Field Communication (NFC) to communicate with the car's NFC reader. This allows you to lock, unlock, and even start the car with just your smartphone.

In terms of security, the digital key is just as secure as a traditional physical car key. The NFC technology used has been extensively tested and is widely used in other industries for secure communication. And, in the case that your smartphone gets lost or stolen, you can easily revoke access to your car through the BMW Connected App.

My personal advice would be to give the digital key a try! It offers a more convenient and secure way to access your car. Just make sure to always keep your smartphone with you when using the digital key feature.
