This design exemplifies comfortable human-machine interaction. The fingerprint sensor is located on the handle grip, allowing the user to verify their identity while holding the handle. This greatly enhances the door unlocking experience. In addition, the unlocking indicator light is integrated into the handle, so that the unlocking status is clear at a glance. The simple and bright touch panel is seamlessly connected with the lock case. The fingerprint sensor is self-learning, which means the longer it is used the higher the fingerprint recognition rate.
