Could you tell me about some long boarding gizmos and gadgets?

Recently traveled by plane but when I do I usually go with the printed boarding pass from home and only hand luggage. That saves a lot of trouble.
This comment reminds me of when I was a student and traveled a lot by train, often the time in the queue at the box office Valencia station was like a train ride. It was amazing what had to be typing and the noise made by the printer to print two lines. Today take a little less, but still take too long in my opinion. And then there are the X-ray of the suitcases in the longhaul. But do not look at people, I guess you can just carry bombs in their pockets.

For as the pump beeps in the metal arc ... padentro XD, very good.
That analogy is very real impression of distance equal to the time ...

The time at airports annoys me, however much you want to use it there is no way I'm capable and I just wasting my time walking around, taking something in returnexhausted and sleepy in the first leg or "papando flies" as they say in my people are places that I did not exactly boost productivity.

Welcome technological advances but also move forward on other things not so technological.
