Avoid touching public touchscreens like store checkouts with the NanoStylus. Limit unnecessary germ exposure and safely use screens. It's also great for phone use with gloves, social media and games.
I love the idea of this so that I don't have to touch germ infested touch screen displays in stores. I would suggest a change in the design, adding an extendable reel type keychain to attach it to. I rigged one up so I can hang it from my pocketbook so it is conveniently handy when I need it. There is a hole in the end of the stylus if you want to hack one yourself.
