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.
Dynamic Intelligent Currency Encryption (DICE) is a technological concept proposed to enhance the security of paper currency. It aims to track and monitor banknotes in circulation by utilizing identifiable characteristics, allowing for the remote devaluation of banknotes implicated in fraudulent activities or criminal transactions. Developed in 2014 by the British-Austrian technology company EDAQS, DICE introduces a security system wherein banknotes are equipped with Machine Readable Codes (MRC) or Radio-Frequency Identification (RFID) tags. These banknotes are then registered to a centralized system, purportedly rendering them secure and resistant to forgery.
One of the primary objectives of DICE is to engage the entire banking and retail sector in a system where cash circulation is passively monitored and controlled. Furthermore, DICE aims to provide an alternative to the complete abolition of physical currency. It proposes to offer the advantages of a cashless economy, such as reduced instances of cash-related crimes, without eliminating cash entirely. (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...)
