Standing-Key / +8615267875233

In most cases, the behavior of waiting for elevator’s coming is inevitable. Replace the traditional press-button with a pressure-sensor Standing Key in front of the elevator.
Every time, you need the elevator, step on Standing-Key then the elevator will come; step out Standing-Key then the elevator will cancel your earlier calling, which saves its unnecessary stop.
By adopting the Standing Key, the elevator becomes more efficient in terms of time and energy and much convenient by saving the behavior of pressing the button, especially for someone who can’t reach the button either because of stuff in hands or physical condition.
