Cash register (Fallout 3)

are containers used for storing Pre-war Money and caps. Some may even contain a few pieces of scrap metal. Typically, ones found in shops that are in use by store keepers afer the Great War contain bottle caps, but ones abandoned in old buildings usually contain Pre-war money. A large amount of cash resisters can be found in the National Archives. Some of them may be locked.

Some shops in the Wasteland have cash registers on their counters, although none are used to store caps earned by the shop despite being lockable. Instead, those caps are usually kept by the scavenger or shopkeeper either in a safe, or on their person. Such a place is Lucky's shop near Tenpenny Tower.
