Generally we don't let our cards out of our sight. Indeed most of the time I handle my own card and it's only rarely that a shop assistant will handle it. (So writing down info isn't a big concern).
The portable POS devices allow the customer to tip as well BTW.
"They" don't run cards much any more. It's a case of consumers putting their own cards into chip+pin devices and keying in their PIN.
Sure @ disputes, we have similar, but it's an extra hassle and not fun.
