Coin-operated
A currency detector or currency validator is a device that determines whether notes or coins are genuine or counterfeit. These devices are used in a wide range of automated machines, such as retail kiosks, supermarket self checkout machines, arcade gaming machines, payphones, launderette washing machines, car park ticket machines, automatic fare collection machines, public transport ticket machines, and vending machines. The process involves examining the coins and/or notes that have been inserted into the machine, and conducts various tests to determine if the currency is counterfeit. Because the parameters are different for each coin or note, these currency acceptors must be correctly programmed for each item to be accepted. In normal operation, if any item such as a coin, banknote, card or ticket is accepted, it is retained within the machine and it falls into a storage container to allow a member of staff to collect it later when emptying the machine. If the item is rejec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vending
A vending machine is an automated machine that provides items such as snacks, beverages, cigarettes, and lottery tickets to consumers after cash, a credit card, or other forms of payment are inserted into the machine or otherwise made. The first modern vending machines were developed in England in the early 1880s and dispensed postcards. Vending machines exist in many countries and, in more recent times, specialized vending machines that provide less common products compared to traditional vending machine items have been created. History The earliest known reference to a vending machine is in the work of Hero of Alexandria, an engineer, and mathematician in first-century Roman Egypt. His machine accepted a coin and then dispensed holy water. When the coin was deposited, it fell upon a pan attached to a lever. The lever opened a valve which let some water flow out. The pan continued to tilt with the weight of the coin until it fell off, at which point a counterweight snapped th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Currency
A currency, "in circulation", from la, currens, -entis, literally meaning "running" or "traversing" is a standardization of money in any form, in use or circulation as a medium of exchange, for example banknotes and coins. A more general definition is that a currency is a ''system of money'' in common use within a specific environment over time, especially for people in a nation state. Under this definition, the British Pound Sterling (£), euros (€), Japanese yen (¥), and U.S. dollars (US$)) are examples of (government-issued) fiat currencies. Currencies may act as stores of value and be traded between nations in foreign exchange markets, which determine the relative values of the different currencies. Currencies in this sense are either chosen by users or decreed by governments, and each type has limited boundaries of acceptance - i.e. legal tender laws may require a particular unit of account for payments to government agencies. Other definitions of the term "curren ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watermark
A watermark is an identifying image or pattern in paper that appears as various shades of lightness/darkness when viewed by transmitted light (or when viewed by reflected light, atop a dark background), caused by thickness or density variations in the paper. Watermarks have been used on postage stamps, currency, and other government documents to discourage counterfeiting. There are two main ways of producing watermarks in paper; the ''dandy roll process'', and the more complex ''cylinder mould process''. Watermarks vary greatly in their visibility; while some are obvious on casual inspection, others require some study to pick out. Various aids have been developed, such as ''watermark fluid'' that wets the paper without damaging it. A watermark is very useful in the examination of paper because it can be used for dating documents and artworks, identifying sizes, mill trademarks and locations, and determining the quality of a sheet of paper. The word is also used for digital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intelligent Banknote Neutralisation System
An intelligent banknote neutralisation system (IBNS) is a security system which protects valuable items by rendering them unusable or easily detectable if an unauthorised individual tries to gain access to them. Dye packs are commonly used to safeguard currency against bank robberies in this manner; when such a pack is taken out of the bank, it releases an indelible dye that stains the money with a conspicuous bright color, making it easy to recognise as stolen. Bonding agents (glues) have been used more recently as alternative degradation agents. Well-neutralised banknotes cannot be brought back into circulation easily. They can be linked to the crime scene and restricted procedures are in place to exchange them at the financial institution. This makes stealing neutralised banknotes uneconomical and impractical. The IBNS removes the anticipated reward of the crime and increases the risk of being caught. This not only foils the theft but acts as a deterrent against further attacks. ...

EURion Constellation
The EURion constellation (also known as Omron rings or doughnuts) is a pattern of symbols incorporated into a number of secure documents such as banknotes and ownership title certificates designs worldwide since about 1996. It is added to help imaging software detect the presence of such a document in a digital image. Such software can then block the user from reproducing banknotes to prevent counterfeiting using colour photocopiers. Description The name "EURion constellation" was coined by security researcher Markus Kuhn, who uncovered the pattern on the 10 Euro (€10) banknote in early 2002 while experimenting with a Xerox colour photocopier that refused to reproduce banknotes. Markus KuhnThe EURion constellation Security Group presentation, Computer Laboratory, University of Cambridge, 8 February 2002. The pattern has never been mentioned officially; Kuhn named it the EURion constellation as it resembled the astronomical Orion constellation, and EUR is the ISO 4217 ...

Counterfeit Detector
Bank note reporters or counterfeit detectors, were periodicals published in the United States in the mid-19th century. They were used by businesses for two purposes: to identify counterfeit bank notes, and to determine the discount rate for notes from distant banks. Before the establishment of a uniform paper currency in the United States, each of the country's hundreds of banks issued its own distinct notes, which led to widespread counterfeiting. Bank note reporters helped merchants and bankers to authenticate notes, by providing descriptions of genuine bank notes, and up to date information on the latest counterfeit bills being passed around. While the notes of local banks generally traded at par, because they could be readily redeemed at the bank for specie (i.e. silver or gold coins), notes issued by more distant banks traded at a discount. These discounts were proportional to the distance of the bank (and hence, the difficulty of redeeming its notes), and were also affected ...
