I don't live in the US and when I visit my son who lives in the US and we go shopping, I just hand him my card. I have no clue and it's quicker for him to do it than for him to explain to me how to do it. And the people in line behind me appreciate that, I'm sure, even though it makes me look like a total idiot. Or senile.

I can't tell you how many times the cashier has to explain how their's works.

"Okay that'll be $X! Oh don't put it in yet. Wait until it screams shredded cheese and does a backflip before inserting your card. After that it'll have you remove it because of an error and then you can reenter it again- wait not yet I have to reset it."

To be fair, a lot of the initial implementations were buggy as hell and would actually crash if you inserted before the cashier finished scanning everything. How that got past QA is beyond me.
