The CarBe module allows the user to unlock, lock, start, and stop their car with their smartphone and biometrics. The module will be installed under the steering column of the car with thumbnail-sized antennas in the door and by the key insert. By using our app, the user can leave their keys behind and simply carry their smartphone. Besides the convenience of never having to carry a key, users can share access to their car with other smartphone users. The biometric authentication that occurs locally on the smartphone allows an extra layer of security for the car owner.
