No Touch®

The No Touch® elevator control system from C.E. Electronics, Inc. streamlines the process of using the elevator without needing to touch common surfaces.
To call an elevator, simply use the up or down buttons in the app to generate the appropriate QR code. Alternatively, type in the floor that you wish to travel to, generate that floor's QR code, and the scanner in the hall will place the appropriate call for up or down. Next, present the floor QR code to the scanner in the elevator and the button in the elevator will light as if it were pressed. 
Frequent destinations can be added as favorites for fast and convenient use. Press and hold the last destination to use it again without retyping.
