Money was historically an emergent market phenomenon that possessed intrinsic value as a commodity; nearly all contemporary money systems are based on unbacked fiat money without use value. Its value is consequently derived by social convention, having been declared by a government or regulatory entity to be legal tender; that is, it must be accepted as a form of payment within the boundaries of the country, for "all debts, public and private", in the case of the United States dollar.
An intelligent banknote neutralisation system (IBNS) is a security system, that is used by banks, ATMs, retail establishments, vending machines and the cash-in-transit industry, to render stolen funds un-useable and easily identifable. Dye packs are inserted between bills in random bundles. If a bundle containing a dye pack is removed from a specified area (i.e. taken out of bank doors), it explodes, releasing an indelible ink dye and possible array of additional chemicals. The conspicuous bright color (usually red) stains on the bills, allow quick easy visual recognition of stolen money. Tracers and markers can also be added to the ink or bonding agent providing forensic evidence linking the criminal to the crime. Bonding agents (i.e. glues) have been used more recently.
Stained bills cannot be brought back into circulation easily, because they are visually and/or forensically linked quickly to the crime scene. Restricted procedures are globally in place in case of an attempt to exchange them at any financial institutions. (Full article...)
The króna (plural: krónur; sign: kr) is the currency of the Faroe Islands. It is issued by Danmarks Nationalbank, the central bank of Denmark. It is not a separate currency, but is rather a local issue of banknotes denominated in the Danish krone, although Danish-issued coins are still used. Consequently, it does not have an ISO 4217 currency code and instead shares that of the Danish krone, DKK. This means that in the Faroe Islands, credit cards are charged in Danish kroner. The króna is subdivided into 100 oyru(r). (Full article...)
