Then who cares if it leaves your sight? Why bring a card processor all the way to my table? I doubt they are that well insured.

Reminded me the first time in the USA, when the waiter ask how I will pay my meal, I said VISA, and he just waited here. I said I need the card processor, and he explained to me that, no, he will take my credit card in the back and to trust him to not steal from me... It's an insane process.

They bring it so you can enter your PIN, most places don't use signatures.
