The process of swiping a magnetic stripe card in a chip terminal is not always as simple as sliding the card through a slot. At some merchants the card must first be inserted in the chip reader, rejected, and only then can it be swiped. This is to prevent the cashier from bypassing the PIN requirement by swiping a chip-enabled card. In other words, the terminal must verify that the card has no chip before it will unlock the swipe reader.

This said, I have never had a swipe card declined in the UK.
