An honesty box is a method of charging for a service such as admission or car parking, or for a product such as home-grown produce and flowers, which relies upon each visitor paying at a box using the honor system. Tickets are not issued and such sites are usually unattended. When used in camping sites and other park settings, they are sometimes referred to as an iron ranger as there is often an iron cash box instead of an actual park ranger. Some stores also use them for selling newspapers to avoid lines at a cash register.
