Actually unless I'm mistaken about a year ago VISA announced that they were extending the same credit card guarantee's they offer to the debit cards that have their logo. When VISA makes announcements like this all the member banks must comply or remove the visa logo from the cards. So the protesting should be the same as with a CC, the rumors I've heard though is that they are much more stickler on the $50 liability for the consumer on debit cards.
