Debit cards are overly common in Europe, and entirely safe. I simply cannot think of a single incident of someone (friends, family) having their debit card hacked since at least 2000. To be honest, most ATMs don't charge money in Europe for a withdrawal, so just head over to the ATM instead of heading for a branch office. That being said, chip cards have been the standard in Europe for a long, long time now. I don't know what kind of debit card your DD has, but if it comes without a chip, chances are that you won't be able to use it.
