A trifold wallet with pockets for notes and cards, and a window to display an identification card
A wallet, or billfold, is a small, flat case that is used to carry personal items such as cash, credit cards, identification documents (driver's license, identification card, club card, etc.), photographs, gift cards, business cards and other paper or laminated cards. Wallets are generally made of leather or fabrics, and they are usually pocket-sized but not always foldable.
The word "wallet" has been in use since the late 14th century to refer to a bag or a knapsack for carrying articles. The word may derive from Proto-Germanic. The ancient Greek word kibisis, said to describe the sack carried by the god Hermes and the sack in which the mythical hero Perseus carried the severed head of the monster Medusa, has been typically translated as "wallet". Usage of the term "wallet" in its modern meaning of "flat case for carrying paper currency" in American English dates to 1834 but this meaning was one of many in the 19th century and early 20th century.
The classicist A. Y. Campbell set out to answer the question, "What...in ancient literature, are the uses of a wallet?" He deduced, as a Theocritean scholar, that "the wallet was the poor man's portable larder; or, poverty apart, it was a thing that you stocked with provisions." He found that sometimes a man may be eating out of it directly but the most characteristic references allude to its being "replenished as a store", not in the manner of a lunch basket but more as a survival pack.
Wallets 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, coin 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.
In recounting the life of the Elizabethan merchant, John Frampton, Lawrence C. Wroth describes the merchant as, "a young English-man of twenty-five years, decently dressed, ..., wearing a sword, and carrying fixed to his belt something he called a 'bowgett' (or budget), that is, a leathern pouch or wallet in which he carried his cash, his book of accounts, and small articles of daily necessity".
In addition to money or currency, a wallet would also be used for carrying dried meat, victuals, "treasures", and "things not to be exposed". Wallets originally were used by early Industrial Americans. It was considered "semi-civilized" in 19th century America to carry one's wallet on one's belt. Ironically, at this time, carrying goods or a wallet in one's pocket was considered uncivilized and uncommon.
In Spain, a wallet was a case for smoking paraphernalia: "Every man would carry a small sheaf of white paper in addition to a small leather wallet which would contain a flint and steel along with a small quantity of so-called yesca, being a dried vegetable fibre which a spark would instantly ignite."
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. Pocket-sized wallets remain extremely popular to this day.

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: this may also be used to describe small cases designed to hold ISO/IEC 7810 cards alone.
Breast wallet (also called a "secretary wallet"): a wallet in which the banknotes are not folded. They are intended for men's breast pocket in a jacket, or for a handbag. Breast wallets will often hold cheques and other monetary documents as they are too large for storage in a pants pocket.
Bi-fold wallet: a type of wallet in which the banknotes are folded over once. Credit cards and identification cards may be stored horizontally or vertically.
Tri-fold wallet: a wallet with two folds, in which credit cards are generally stored vertically.
Front pocket wallet (or money clip): a case with no currency compartment and very few pockets for cards. Usually banknotes are folded and held to the wallet with a metal clip.
Long wallet: a larger wallet usually worn with jeans, fastened by a chain, strap, or leather rein. Bills are held flat, and long wallets typically have a coin purse. Popularized by bikers to secure their wallets while riding a motorcycle, smaller chained wallets became popular in 1970s−'80s Punk fashion and in the early 1990s with the grunge fashion movement as well as Heavy metal fashion. Long wallets are popular with men in cash-based countries like Japan and often reflect Native American aesthetic influence.
Wallet band a type of wallet that uses a continuous elastic band, made of fabric or rubber, to secure cards and/or cash. Wallet bands have become increasingly more popular as a way to reduce the bulk of a traditional wallet.
Wrist wallet: a type of wallet that can be secured to the wrist, to keep one's hands free.
Travel wallet: used by travellers to hold essential documentation together, such as passports, tickets, boarding passes, foreign currency, travellers cheques, itinerary, travel insurance, hotel booking information, and other similar items.
ID case/"Neck pouch": thin nylon or leather cases with plastic see-through compartments designed to hold an ID card. Usually worn around the neck, many have extra pockets for holding small items, hence they also function as wallets.
Shoewallet: a small pouch attached to a shoe to be used as a wallet designed primarily for people exercising
Digital wallet: a computer file for maintaining digital currency.
Side by side wallet: divides the contents into two stacks instead of one, so it is half as thick. May be made of very thin fabric. Patented.
Most major designers offer seasonal and perennial wallet collections of black and brown leather. Major retailers also sell a wide selection of men's wallets, including branded and house-name wallets.
The traditional material for wallets is leather or fabric, but many other flexible flat sheet materials can be used in their fabrication. Non-woven textiles such as Tyvek are used, sometimes including reuse of waterproof maps printed on that material. Woven metals, such as fine mesh made of copper or stainless steel have been incorporated into wallets that are promoted as having electromagnetic shielding properties to protect against unauthorized scanning of embedded RFID tags. Do-it-yourself websites such as Instructables feature many projects for making wallets out of materials such as denim, Kevlar, or duct tape.
Some wallets, particularly in Europe where larger coins are prevalent, contain a coin purse compartment. Some wallets have built-in clasps or bands to keep them closed. As European banknotes, such as Euros and Pounds, are typically larger than American banknotes in size, they do not fit in some smaller American wallets.
