Paper money is slowly on the way out but retreating from cash services all together may have some repercussions for those who rely on it. A new Reserve Bank discussion document called Future of Money - Cash System Redesign outlines some of the challenges and possible solutions for traditional paper money.

Dr Claire Matthews is the Director of academic programmes at Massey's Business School and joins Karyn to discuss who might have to foot the bill.
