A wallet, or billfold, is a small, flat case used to carry personal items such as cash, credit cards and identification documents, such as a driver's license. Wallets are generally made of leather or fabrics, and they are usually pocket-sized.
Billfolds were developed after the introduction of paper currency to the West in the 1600s. (The first paper currency was introduced in the New World by the Massachusetts Bay Colony in 1690.) Prior to the introduction of paper currency, purses (usually simple drawstring leather pouches) were used for storing coins. Early wallets were made primarily of cow or horse leather and included a small pouch for printed calling cards.
The modern bi-fold wallet with multiple "card slots" became standardized in the early 1950s with the introduction of the first credit cards. Some innovations include the introduction of the velcro-closure wallet in the 1970s.
Wallets are usually designed to hold banknotes and credit cards and fit into a pocket (or handbag). Small cases for securing banknotes which do not have space for credit cards or identification cards may be classified as money clips.
Some wallets, particularly in Europe (where larger denominated coins are more prevalent) contain a coin purse compartment. Some wallets have built-in clasps or bands to keep them closed. As European banknotes(pounds, euros) are larger than American banknotes in one dimension, they don't fit in some smaller American wallets.
It is generally accepted that wallets don't hold actual coinage change - If a wallet is used to hold coins then it automatically becomes known as a purse.
A wallet generally has one or more currency pockets; in some cases, there may also be a money clip. Wallets usually have one or more pockets for storing credit card or identification cards, which may be oriented vertically or horizontally.
Wallets may also have an identification pocket, which facilitates the display of a regularly-used piece of identification such as workplace ID or a bus pass, by housing it within a transparent "window". A wallet may also have photo pockets, which are designed to hold a collection of small personal photographs. A wallet may also have a small pouch for coins or keys.
Some wallets are attached to metal chains which are then clipped onto a belt, as a way of preventing loss or theft by pickpockets. Some travellers replace wallets with money belts, which are belts with a hidden money compartment.
