The dirham (Arabic: درهم, plural: دراهم) is the currency of Morocco. The plural form is pronounced darahim, although in French and English "dirhams" is commonly used. Its ISO 4217 code is "MAD". It is subdivided into 100 santimat (singular: santim, Arabic singular: سنتيم, plural: سنتيما or سنتيمات). The dirham is issued by the Bank Al-Maghrib, the central bank of Morocco. While the dirham is a fully convertible currency, export of the local currency is prohibited by law, but seldom controlled.
A banknote (often known as a bill, paper money, or simply a note) is a type of negotiable instrument known as a promissory note, made by a bank, payable to the bearer on demand. When banknotes were first introduced, they were, in effect, a promise to pay the bearer in coins, but gradually became a substitute for the coins and a form of money in their own right. Banknotes were originally issued by commercial banks, but since their general acceptance as a form of money, most countries have assigned the responsibility for issuing national banknotes to a central bank. National banknotes are legal tender, meaning that medium of payment is allowed by law or recognized by a legal system to be valid for meeting a financial obligation. Historically, banks sought to ensure that they could always pay customers in coins when they presented banknotes for payment. This practice of "backing" notes with something of substance is the basis for the history of central banks backing their currencies in gold or silver. Today, most national currencies have no backing in precious metals or commodities and have value only by fiat. With the exception of non-circulating high-value or precious metal issues, coins are used for lower valued monetary units, while banknotes are used for higher values.
