I don't buy this. If someone can operate a car, then they can operate a mobile phone well enough to open an app and scan it.
I couldn't. I could after someone showed me how, but I would probably have trouble working it out from scratch. The couple of times I was given a phone to do something on, I couldn't even turn the thing on. Everything is easy after you know how. It is a black box until you do.
