Most Chip and pin readers still have a mag stripe reader built into the unit. Some of the time it takes some finding (look for a slot running along the right side or the top). Those that don't will have a mag stripe reader built into the till itself.
The only issue you might find with the mag stripe cards is that some younger cashiers have never had to deal with them before and so will have no idea what to do with them (I had this issue when i moved back to the UK).
