Banknote
A banknote—also called a bill (North American English), paper money, or simply a note—is a type of negotiable promissory note, made by a bank or other licensed authority, payable to the bearer on demand. Banknotes were originally issued by commercial banks, which were legally required to redeem the notes for legal tender (usually gold or silver coin) when presented to the chief cashier of the originating bank. These commercial banknotes only traded at face value in the market served by the issuing bank.[1] Commercial banknotes have primarily been replaced by national banknotes issued by central banks or monetary authorities.
National banknotes are often – but not always – legal tender, meaning that courts of law are required to recognize them as satisfactory payment of money debts.[2] 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.
Code of Hammurabi Law 100 (c. 1755–1750 BC) stipulated repayment of a loan by a debtor to a creditor on a schedule with a maturity date specified in written contractual terms.[3][4][5] Law 122 stipulated that a depositor of gold, silver, or other chattel/movable property for safekeeping must present all articles and a signed contract of bailment to a notary before depositing the articles with a banker, and Law 123 stipulated that a banker was discharged of any liability from a contract of bailment if the notary denied the existence of the contract. Law 124 stipulated that a depositor with a notarized contract of bailment was entitled to redeem the entire value of their deposit, and Law 125 stipulated that a banker was liable for replacement of deposits stolen while in their possession.[6][7][5]
In China during the Han dynasty, promissory notes appeared in 118 BC and were made of leather.[8] Rome may have used a durable lightweight substance as promissory notes in 57 AD which have been found in London.[9] However, Carthage was purported to have issued bank notes on parchment or leather before 146 BC. Hence Carthage may be the oldest user of lightweight promissory notes.[10][11][12] The first known banknote was first developed in China during the Tang and Song dynasties, starting in the 7th century. Its roots were in merchant receipts of deposit during the Tang dynasty (618–907), as merchants and wholesalers desired to avoid the heavy bulk of copper coinage in large commercial transactions.[13][14][15] During the Yuan dynasty (1271–1368), banknotes were adopted by the Mongol Empire. In Europe, the concept of banknotes was first introduced during the 13th century by travelers such as Marco Polo,[16][17] with European banknotes appearing in 1661 in Sweden.
Counterfeiting, including the forgery of banknotes, is an inherent challenge in issuing currency. It is countered by anticounterfeiting measures in the printing of banknotes. Fighting the counterfeiting of banknotes and cheques has been a principal driver of security printing methods development in recent centuries.
Vending machines and banknotes[edit]
In the late 20th century, vending machines were designed to recognize banknotes of the smaller values long after they were designed to recognize coins distinct from slugs. This capability has become inescapable in economies where inflation has not been followed by introduction of progressively larger coin denominations (such as the United States, where several attempts to make dollar coins popular in general circulation have largely failed). The existing infrastructure of such machines presents one of the difficulties in changing the design of these banknotes to make them less counterfeitable, that is, by adding additional features so easily discernible by people that they would immediately reject banknotes of inferior quality, for every machine in the country would have to be updated.

A banknote is removed from circulation because of everyday wear and tear from its handling. Banknotes are passed through a banknote sorting machine to assess their authenticity and fitness for circulation, or may be classified unfit for circulation if they are worn, dirty, soiled, damaged, mutilated or torn. Unfit notes are returned to the central bank for secure online destruction by high-speed banknote sorting machines using a cross-cut shredder device similar to a paper shredder with security level P-5 (pieces smaller than 30 mm2) according to the standard DIN 66399–2. This small size decomposes a banknote into typically more than 500 tiny pieces and rules out reconstruction like a jigsaw puzzle because the shreds from many banknotes are commingled.
A subsequent briquettor compresses shredded paper material into a small cylindrical or rectangular form for disposal (e.g. landfill or burning).[73] Before the 1990s, unfit banknotes were destroyed by incineration, with a higher risk of manipulations.
When a Federal Reserve Bank of the United States receives a cash deposit from a commercial bank or another financial institution, it checks the individual notes to determine whether they are fit for future circulation.[74] About one-third of the notes that the Fed receives are unfit, and the Fed destroys them. US dollar banknotes last an average of more than five years.[75]
Contaminated banknotes are also decommissioned and removed from circulation, primarily to prevent the spread of diseases. A Canadian government report indicates:
In the US, the nickname "Fed Shreds" refers to paper money which has been shredded after becoming unfit for circulation. Although these shredded banknotes are generally landfilled, they are sometimes sold or given away in small bags as souvenirs or as briquettes.[77]
Polymer banknotes may be shredded and then melted down and recycled to form plastic products like building components, plumbing fittings, or compost bins.[78]
Intelligent banknote neutralisation systems[edit]
Intelligent banknote neutralisation systems (IBNS) are security systems which render banknotes unusable by marking them permanently as stolen with a degradation agent. Marked (stained) banknotes cannot be brought back into circulation easily and can be linked to the crime scene. Today's most used degradation agent is a special security ink which cannot be removed from the banknote easily and not without destroying the banknote itself, but other agents also exist. Today IBNSs are used to protect banknotes in automated teller machines, retail machines, and during cash-in-transit operations.
Dynamic Intelligent Currency Encryption[edit]
Dynamic Intelligent Currency Encryption (DICE) is a security technology introduced in 2014 by British company EDAQS, which devaluates banknotes remotely that are illegal or have been stolen. The technology is based on identifiable banknotes – that could be an RFID chip or a barcode – and connects to a digital security system to verify the validity of the banknote. The company claims that the banknotes are unforgeable and contribute to solve cash-related problems as well as fight crime and terrorism. In another note, the DICE benefits cover and solve almost all cash-related issues that are seen by governments to be a motivation for the progressive abolition of cash.[79]
Confiscation and asset forfeiture[edit]
In the United States there are many laws that allow the confiscation of cash and other assets from the bearer if there is suspicion that the money came from an illegal activity.[80] Because a significant amount of U.S. currency contains traces of cocaine and other illegal drugs, it is not uncommon for innocent people searched at airports or stopped for traffic violations to have cash in their possession sniffed by dogs for drugs and then have the cash seized because the dog smelled drugs on the money. It is then up to the owner of the money to prove where the cash came from at his own expense. Many people simply forfeit the money.[81] In 1994, the United States Court of Appeals, Ninth Circuit, held in the case of United States of America v. U.S. Currency, $30,060.00 (39 F.3d 1039 63 USLW 2351, No. 92-55919) that the widespread presence of illegal substances on paper currency in the Los Angeles area created a situation where the reaction of a drug-sniffing dog would not create probable cause for civil forfeiture.[82]
