Complementary currency is a
hypernym (superordinate) of
local currency (also referred to as community currency) and
sectoral currency.Complementary currencies describe a wide group of
currencies or
scrips designed to be used in combination with standard currencies or other complementary currencies. They can be valued and exchanged in relationship to national currencies but also function as
media of exchange on their own. Complementary currencies lie outside the nationally defined legal realm of
Legal tender and are not used as such. Rate of exchange, scope of circulation and use in combination with other currencies differs greatly between complementary currency systems, as is the case with national currency systems.
