Cash register

A cash register is a container found throughout Fallout 3, Fallout: New Vegas, and Fallout 4.

Characteristics
Cash registers were ubiquitous in shops prior to the Great War, used to store money and record transactions. Though they are used far less commonly in post-War society, registers can be found throughout the Capital, Commonwealth, and Mojave Wastelands, in both active and abandoned stores.

Registers in active shops generally contain bottle caps, while those in abandoned buildings usually contain pre-War money. Many also contain bobby pins and the occasional piece of scrap metal.

Fallout 3

 * A large amount of cash registers can be found in the National Archives.
 * A decent amount can be found at the Super-Duper Mart, with most of them containing pre-War money.

Fallout: New Vegas

 * There are several cash registers throughout the casino and cocktail lounge levels of the Lucky 38 Casino.
 * In the Dead Money add-on, the ruins of the Sierra Madre contains many registers. Some may even have the Vending machine code "Return outfit item".

Fallout 4

 * Many cash registers can be found at the Super-Duper Mart and the adjecent Lexington bank.
