It is the same concept as the fingerprint authentication system common in smartphones. It is applied to various devices related to security. For example, in some vehicles equipped with a fingerprint authentication module, if you register your fingerprint in advance through the infotainment system, you can open the door and start the engine by fingerprint authentication even without the key. In addition, a personalized profile, including driving posture, can be called up only by fingerprint authentication, and also, payment functions such as valet mode and CarPay can be used.
