‘Door butler’ is a doorknob designed for the aged who have memory decay and make slips.
You can input your family’s fingerprint information into ‘Door butler’ with simple operation and afterwards, only gripping doorknob without using keys or inputting passwords, you can go in and out.
The shape of ‘Door butler’ is designed to recognize fingerprint information naturally by only gripping ‘Door butler’ with your hand smoothly. And when gripping doorknob, by pulling or pushing, you can open the door without turning or downing it, so you can always open the door conveniently as if the door were not locked.
