In some parts of the world MasterCard is offering its "Debit MasterCard" instead of or alongside its Maestro brand which is a debit only system.
Question is: Which one has been there longer and why would they introduce the other one? I suppose they are processed over two different systems but that is the only difference I see between a Maestro card and a Debit MasterCard.
Does anyone know about historical or other reasons for this?
