A bifold is a small folding case or wallet used for carrying personal items such as credit cards, cash and identification cards. A bifold is composed of two panels which usually feature an inner face with compartments and a plain outer face. When the folds are away from each other, the bifold can be opened on the upper edge to allow the placement of paper money or small documents.
