For touch screens and other devices where a small number of keystrokes are necessary (such as copier control screens and elevator buttons), we recommend the “knuckle” input method where you use a finger’s knuckle to press buttons or click areas on screen. While the surface and your hands should still be sanitized after this process, using the back side of your hand for input activities in this way greatly reduces the chance of you transmitting germs to or from your face.
