A low profile banknote stacker/dispenser uses a central diverting switch provided intermediate two opposed banknote stackers. The stack of banknotes is passed from one banknote stacker to the other banknote stacker, and the central switch allows a new banknote to be added and aligned with the banknote stacker. The banknote stacker is then passed in the opposite direction for the addition of a further banknote to the banknote stacker. This oscillating modular design is space efficient and cost effective.
