This. In Holland we have chip and pin, which I've got to say goes much faster than someone can fish out cash from their wallet, certainly faster than someone can make change.
Recently many places also support RFID with no pin required for small purchases (I think it's €25). Goes much faster than the employee can bag your order up.
We are starting to see it in the UK as well, it is very fast.
Our cards here in Portugal already support it as well, but the payment readers seem to be lagging behind.
