Definitely possible if standards are defined, but that is not the problem. The real one is that we now have a security industry that needs to apply tech to dangers that in reality don't really exist in the first place or are so minuscule that you need sales people to market these. The security hysteria of the last decade is laughable, if it didn't cost us that much...

I seriously avoid flights. They already have my data a thousand times but I am just sick of these perverse boarding processes. Wasn't good for the environment anyway.
