Google wants to turn your Android phone into a digital key

Not long from now, you may use your Android smartphone to unlock your car. Google is working toward an all-digital future where all you may need to carry with you is your phone with its efforts surrounding the “Android Ready SE Alliance.” 

Google’s push is based on a hardware component referred to as a “secure element,” and it’s designed to run secure computer-based tasks similar to how NFC payments work. Under this system, you’d be using your phone for a wider variety of purposes, such as unlocking your car without the need for a physical key.
