ABSTRACT:
BACKGROUND ART
Numerous devices have been previously developed for identifying documents and determining their authenticity. Likewise, devices have been previously developed for determining the denomination and authenticity of bank and currency notes. Such devices commonly test different properties of a presented note and based on the properties sensed, give an indication of the denomination and/or authenticity of the presented note. All such prior art devices have limitations.
Many prior art devices require precise alignment of the note during sensing of its properties. This requires the device to include a mechanism to align the notes and often limits the speed at which the notes can be processed. In addition, some devices require that presented notes be oriented in a particular way as they are sensed. This limits their usefulness as notes are often not presented in a uniform orientation.
Many prior art devices for determining note denomination and validity are capable of processing only a small number of note types. This presents drawbacks as other note types cannot be processed. Such prior art devices are also generally made to be used with only one type of currency bills such as the currency of a particular country. Often it is difficult or impossible to adapt such devices to handle currencies of countries which have different physical properties. Furthermore, it may be difficult to adapt such devices to a new printing series of notes within the same country.
Many prior art devices are also amenable to compromise by counterfeit notes. It is becoming easier to produce highly accurate counterfeit reproductions of currency. By mimicking the properties of a note that are tested by prior art currency denominators and validators, it is often possible to have counterfeit notes accepted.
To minimize the risk of acceptance of counterfeits, the range of the acceptance criteria in prior art devices can often be set more closely. However, currency notes in circulation change properties through use fairly quickly. Notes in circulation may change their properties through handling and wear. Notes may become dirty or marked with ink or other substances. Notes may also lose their color due to having been mistakenly washed with clothing or exposed to water or sunlight. Prior art currency denominators and validators may reject valid notes which exhibit such properties when the criteria for acceptance is set too tightly.
Note denominators and validators currently available may also be difficult to program and calibrate. Such devices, particularly if they must have the capability of handling more than one type of note, may require significant effort to setup and program. In addition, such devices may require initial calibration and frequent periodic recalibration and adjustment to maintain a suitable level of accuracy.
Prior art note denominators and validators, particularly those having greater capabilities, often occupy significant physical space. This limits where they may be installed. In addition, such devices also often have a relatively high cost which limits their suitability for particular uses and applications.
Prior art devices for determining the conditions of notes are not as effective and accurate as would be desired. For example, it is often desirable to determine that a note has a condition that requires special handling. This may include conditions such as that the note is a double note, that the note is soiled or that the note is worn. There is further often a desire to segregate notes, that although determined as genuine, have a condition that makes it undesirable to deliver the notes into circulation.
There may be a desire in automated banking machines and other types of machines where transactions are conducted, to determine the particular bank notes that were involved in a given transaction. This may be useful in the investigation of criminal activities. For example it may be desirable to determine transaction information such as the identity of an individual depositing notes into an automated banking machine when one or more of the notes deposited are suspect as to genuineness, or upon the sensing of other conditions. Similarly tracking the particular currency bills that are dispensed from a banking machine may be useful for tracking the source of a payment.
It is also becoming more common for automated banking machines to include devices for authenticating instruments such as checks. Automated banking machines which have this capability generally include a dedicated device for reading and imaging checks. Such devices are often complex and expensive and they may add substantially to the initial purchase price and service cost associated with operating an automated banking machine.
Thus, there exists a need for a currency note denominator and validator which is more accurate, has greater capabilities, is faster, smaller in size, and lower in cost. There further exists a need for an apparatus and method that may be used to accurately and reliably determine a condition of a note. There further exists a need for a device which may be used in an automated banking machine to determine the identity of particular currency bills involved in a particular transaction. There further exists a need for a device which can serve the functions of both a currency denominator and validator and an acceptor and imager for instruments deposited in an automated banking machine.
