does the shop till know whether it's talking to a plastic card, or

It must do, otherwise other tills wouldn't know to ignore the £30 limit.
But does the till know that, or does it just present the amount to the
card, and the card or iThing gives a yes/no answer with some sort of
token to prove it?
