Bosch wants to replace your car keys with a smartphone and an app

Perfectly Keyless stores a digital car key directly in the user’s smartphone via a purpose-designed app. When the driver approaches the car, digital key-management software connects the smartphone to sensors built into the vehicle via the cloud. The sensors instruct a special control unit to unlock the car if they recognize the key. Bosch pledges the technology is as secure as fingerprint identification; there’s no way to open a car if the sensors don’t recognize the unique digital key.
