The ORVIBO Smart Lock C1 is the first intelligent access control system designed for apartment, office and home. It follows basic design principles. The circular fingerprint identification design on the door lock handle unlocks the door for you naturally when you place your hand on the handle. Breaking away from the common lock's single and purely mechanical protection mechanism, you can use a password, fingerprint, card or app to open the door. The door lock handle is a round fingerprint button that you can easily place your thumb on.
