A currency detector or currency validator is a device that determines whether notes or coins are genuine or counterfeit. These devices are used in many automated machines found in retail kiosks, 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 by using various tests, determining 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 rejected, the machine returns the item to the customer. If a coin or token is rejected, it usually falls into a tray or rolls out of a slot at the bottom where the customer can remove the coin. If a banknote, card or ticket is rejected, it is pushed back out through the machine so that the customer can remove it from the slot into which it was inserted. Read Full Article Here
