Definitions

  • the present invention relates to the field of currency validators and more specifically to the system of a currency validator having the capability to record and store the image of rejected bills inserted into the currency validator.
  • Currency validators incorporating optical sensor technology typically consisted of one or more photo detectors sensing light from a LED, bulb, or other light source either transmitted through, or reflected from currency. Early units utilized a limited number of light sources, but recent units are capable of utilizing multiple light sources.
  • the machine will reject his note as the US notes do not resemble the stored information for a Euro note. When this rejection is complete, a record is kept of the fact that a note was inserted and not recognized by the validator. Since the US note is so different from the Euro note, it is relatively easy for the machine to determine that it is not a note that should be recognized. However, when the owner of the machine reviews machine performance, the reason this note was rejected will not be readily apparent.
  • currency validators will record limited information of rejected notes - given the large number of currencies available; the ability of the machine to record detailed information about the type of rejected note inserted into the machine is limited. Normally, currency validators only store limited, basic information. For example, the machine will keep a record of the number of notes it rejected.
  • High resolution scanning technology developed by Global Payment Technology is described, for example, in U.S. Patent Application, Ser. No. 11/473,368, which disclosure is fully incorporated herein by reference. This technology has been incorporated into the present invention. This technology allows sub-millimeter scans to be taken, and currency validators incorporating this high resolution scanning technology can capture data that permit a high resolution picture of a banknote, allowing new and improved applications such as being able to convey to the user validator performance.
  • this invention provides the operator and the validator manufacturer the ability to determine the incidence of incorrect notes, fraud notes, etc., that are included in the rejection category.
  • the invention enables the validator manufacturer to screen out the rejects for incorrect notes, mutilated notes and isolate the remaining rejects into security violations (fraud insertions) and database outliers (good notes that are rejected for wear).
  • the invention provides a method to incorporate this information into subsequent releases of the product to improve the acceptance of good notes in validators.
  • the present disclosure provides a currency validator having the capability to record and store images of rejected bills inserted into the currency validator, permitting the operator to determine the reasons for the rejection of a particular bill.
  • a currency validator is comprised of a note transporter module, a data collection module, and a processing module.
  • a second aspect of the present disclosure includes a currency validator comprising a channel configured to accommodate a note, a note transporter module configured to transport the note through the channel, at least one illuminator configured to illuminate a width of the channel, a photodetector array, a lens associated with the photodetector array, an internal memory configured to store data collected from the photodetector array, and a removable storage medium, placed in communication with the internal memory.
  • a third aspect of the present disclosure includes a currency validator comprising a channel configured to accommodate a note, a transporter configured to transport the note through the channel, a photodetector array, at least one illuminator configured to illuminate a width of the channel, a lens associated with the photodetector array, a memory store configured to store data collected from the photodector array, and a communications means connected to the memory store allowing the data from a rejected note to be transferred to a storage medium outside the validation device.
  • Figure 1 is a side view of a high resolution scanning system of a currency validator, according to an exemplary disclosed embodiment.
  • Figure 2 is a schematic diagram of a linear array and a processing module, according to an exemplary disclosed embodiment.
  • Figure 3 is a flow chart of a currency validation process.
  • Fig. 1 a side view of a high resolution scanning system of a currency validator, according to an exemplary disclosed embodiment.
  • the currency validator 1 comprises several components, including one or more of a note transporter module 10, a data collection module 20, and a processing module 30.
  • Note transporter module 10 may be any suitable note transporter known in the art. Note transporter module 10 may be configured to transport note
  • Note transporter module 10 may be constructed of an opaque material such as black ABS plastic. However, note transporter module 10 may be constructed of other suitable materials including, but not limited to, plastic, glass, or metal which may be opaque or transparent. Note transporter module 10 may include transmission window 8, which may be disposed between note 2, and lens
  • Note 2 may be transported through note transporter module 10 at a rate such that a specific number of lines of note 2 may be scanned (e.g., one line for each wavelength may be scanned every 0.6 mm of note 2). The rate may be incremental or substantially continuous.
  • a data collection module 20 may comprise multiple components.
  • a data collection module 20 includes a printed circuit board 6 on which various components may be attached.
  • the printed circuit board 6 may be mounted substantially parallel with a bottom surface of note transporter module 10 and/or a plane including note 2 as it travels through note channel 11 , however, any suitable configuration that allows scanning of note 2 will suffice.
  • Printed circuit board 6 may include any number of components necessary to scan and process a note 2, for example, light pipe 21 , fold mirror 22, and LEDs 7, 9.
  • Lens 3 may be mounted to lens mount 4, which may in turn itself be mounted to printed circuit board 23.
  • a linear array 5 may be configured on the printed circuit board 23.
  • Lens 3 may be mounted such that an entire width of note channel 11 is viewable by linear array 5, for example, via transmission window 8.
  • the distances between lens 3, linear array 5, and note 2 may be jointly or independently set and controlled by any suitable mechanism and/or method.
  • Lens 3 may be configured such that an entire width of note channel 11 is focused on linear array 5, even if linear array 5 has a width that is less than a width of note channel 11.
  • Linear array 5 may be any suitable note scanning array.
  • the linear array 5 is a row of sensors configured to take a simultaneous scan of a line of an object, e.g., an entire width of a note 2. This is in contrast to individual photo detectors used in conventional currency validators, which are only configured to scan and collect data relative to one point of note 2. Even a plurality of individual photo detectors can only scan a plurality of points, and not an entire line of data.
  • An example of a linear array 5 that may be used includes a TSL1401 R, 128 x 1 array manufactured by TAOS INC.
  • the TSL1401 R is well adapted for use in note scanning.
  • Some generally desirable features of a linear array 5 which the TSL1301 R possesses includes a good response to a wide frequency range (e.g., between about 350 and about 980 nm), a wide dynamic range (e.g., about 72 dB), a linear response across the array (e.g., ⁇ 4%), a pixel readout frequency of about 8 MHz, and a sufficient number of pixels across the array (e.g., 128) to give sub-millimeter resolution without generating excessive data.
  • a wide frequency range e.g., between about 350 and about 980 nm
  • a wide dynamic range e.g., about 72 dB
  • a linear response across the array e.g., ⁇ 4%
  • a pixel readout frequency e.g
  • Each pixel on the array may be specified to be within about +/- 7.5% of the average of all pixels in the array, over temperature.
  • Linear array 5 may be configured to scan a note 2 having a width of about 8 mm (i.e., about a width of linear array 5 itself) up to at least a note 2 having a width of about 90 mm (i.e., suitably width enough to accommodate substantially all paper currencies).
  • Each pixel may scan a line of note 2 having a width in a direction of travel of note 2 of about 0.67 mm.
  • linear array 5 may scan a line of note 2 about every 0.6 mm per wavelength.
  • the device is physically small, inexpensive and is well adapted to use with commercially available lenses, thereby reducing overall costs for use in a note validator.
  • the device can be used over a wide voltage range, making it suitable for use, for example, with both 5 volt and 3.3 volt based systems.
  • the currency validator 1 and/or data collection module 20 may include one or more illuminators or sets of illuminators such as LEDs 7, 9 used to illuminate transmission window 8.
  • One set of LEDs 7 may be configured to emit light having a frequency different from a second set of LEDs 9.
  • LEDs 7, 9 may also or alternatively be connected and controlled such that only one set of LEDs which emit light at one frequency may be illuminated at any point in time.
  • LEDs 7 may be 660 nm red LEDs, and LEDs 9 may be 880 nm infrared LEDs. At any one time, LEDs 7 and/or LEDs 9 may be illuminated.
  • LEDs 7, 9 may emit any color, for example, red, infrared, ultraviolet, or any other wavelength in the visible or non-visible spectrum.
  • Fig. 2 illustrates the linear array 5 and the various components of the processing module 30.
  • the processing module 30 may include a printed circuit board 6 and one or more of amplifier 10, (Analog-to-digital) A/D converter 11 , CPU 12, (Digital-to-analog) D/A converter 13, and LED driver circuitry 14.
  • Processing module 30 may control components of the data collection module 20: including, one or more of LEDs 7, 9, linear array 5, and lens 3.
  • a combination of CPU 12, D/A converter 13, and LED driver 14 may control LEDs 7, 9.
  • CPU 12 may be used to set the intensity and/or duration of light output from LEDs 7, 9.
  • a digital signal indicating such may thus be sent from CPU 12 to D/A converter 13, which may convert the digital signal into an analog signal, and then that signal may be sent to LED driver 14, which in turn will control the intensity and duration of light out from LEDs 7, 9 at the predetermined levels.
  • CPU 12 may be used to determine which set of LEDs 7, 9 are illuminated.
  • CPU 12 may send a signal COLOR to LED driver 14 indicating that only one color set of LEDs 7, 9 are to be illuminated at a given time. LED driver 14 will thus illuminate the proper set of LEDs 7, 9.
  • LEDs 7, 9 may be illuminated on alternate exposure cycles by LED driver 14, which may result in a multi-color scan of note 2. For example, for a two color scan of note 2, a line of note 2 will be read about every 0.3 mm, alternating wavelengths of LEDs 7, 9, resulting in one scan for each wavelength every 0.6 mm. Additional colors can be added and/or selected by adding more LEDs and/or control signals, for example, blue (470 nm) or green (565 nm). No matter how many color(s) are used, however, the process of scanning may be consistent.
  • a combination of CPU 12, A/D converter 11 , and amplifier 10 may control and/or receive data scanned from note 2 by linear array 5.
  • linear array 5 may be functionally connected to CPU 12 through signals STROBE and CLK.
  • STROBE and CLK For example, in order to signal to linear array 5 to scan (e.g., capture light) note 2 and/or note channel 11 , CPU 12 may set the STROBE function on high and send that signal to linear array 5.
  • Linear array 5, being a scanner, may then turn "on" and begin to scan data reflected and/or transmitted from note 2 and/or note channel 11 from one or more of LEDs 7, 9.
  • CPU 12 may set the STROBE function on low, and send the signal to linear array 5 to end scan.
  • the timing between these STROBE signals may be used to control the amount of time linear array 5 is exposed to note 2 for each scan. Such exposure time may have been set and/or previously determined as necessary to provide sufficient light to linear array 5 from note 2 that can be converted into useful data.
  • one exposure can be taken per 0.6 mm of length of note. This causes a slight overlap between pixels along the note so that there are no gaps between pixels.
  • 3 colors an exposure is taken in red, the note moves 0.2 mm during the exposure, then an exposure is taken in Blue, the note moves 0.2 mm during the exposure, then an exposure in IR, the note moves 0.2 mm, and the next exposure would be in Red again.
  • More colors can be used if the exposure time is shortened such that a total time for all the colors is still less than the size of the pixel (such as 0.67mm in the TSL1401 R array) given the reduction factor used (about 10.5- 11x). Accordingly, given a 150 mm long note 223 exposures per color (150/0.67) can occur.
  • linear array 5 may receive and convert light from note 2 and/or note channel 11 into analog data, and may hold that analog data in holding registers of linear array 5.
  • CPU 12 may then clock CLK and send that signal to linear array 5.
  • linear array 5 may send the data stored in holding registers to amplifier 10 as signal PIXELS.
  • Signal PIXELS may be amplified and buffered by amplifier 10, and then sent to A/D converter 11.
  • A/D converter 11 may sample the input, convert the analog signal into a digital representation of the input, and present the digital representation of signal PIXELS to CPU 12.
  • CPU 12 may then store PIXELS in internal memory 16. This process may be repeated until all pixels of the array have been processed.
  • CPU 12 and/or linear array 5 may provide the capability of clocking out the electrical signal while capturing the next exposure, e.g., line of scanned data from a width of note 2, thus providing a continuous sampling and conversion process.
  • Currency validator 1 shown in Figs. 1 and 2 is primarily configured to scan data (e.g., light) reflected from note 2. For example, light is transmitted from one or more of LEDs 7, 9 through transmission window 8, reflected off a surface of note 2 back through transmission window 8 onto lens 3, and then focused onto linear array 5 using lens 3.
  • data e.g., light
  • light is transmitted from one or more of LEDs 7, 9 through transmission window 8, reflected off a surface of note 2 back through transmission window 8 onto lens 3, and then focused onto linear array 5 using lens 3.
  • a second set of independent LEDs (e.g., transmissive LEDs 102, 103 mounted on frame 101 ), mounted on a side of note transporter module 10 substantially opposite to linear array 5 and the first set of LEDS 7, 9, may be used to illuminate note 2.
  • the light passing through note 2 from this second set of LEDs 102, 103 may be scanned by linear array 5 in substantially the same way that reflected light is scanned using the first set of LEDs (e.g., reflective LEDs 7, 9) mounted on the same side of note transporter module 10 as linear array 5.
  • the second set of LEDs 102, 103 may be illuminated when the first set of LEDs 7, 9 are turned off, and the first set of LEDs 7, 9 may be turned on while the second set of LEDs 102, 103 are turned off.
  • the processing unit now proceeds through the steps of recognizing and validating the note.
  • a note is verified, it is typically stored in a box or stacker that secures the note until the stacker is collected at a later time.
  • the validator takes the information gathered from the sensor that is stored in internal memory 16 and transfers this information preferably to an easy to access removable storage medium 17.
  • the removable storage medium 17 may include a SD card, a compact flash card, a USB drive, or any other portable storage medium known in the art.
  • Removable storage medium 17 is connected to the processing system through a connector that allows the card to be easily inserted and removed from the currency validator 1.
  • Removable storage medium 17 will preferably have a file system access method that allows the card to be quickly read by a PC.
  • Data on the removable storage medium 17 would be arranged in files, with each file representing a single instance of a rejected insertion.
  • the data on the removable storage medium 17 would be read by the database designers at the manufacturer. This data can be read by physically transporting the removable storage medium 17 to the manufacturer, or by transmitting the data on the removable storage medium 17 to the manufacturer.
  • Data from the removable storage medium 17 would be displayable on a PC used by the operator to allow the operator to quickly look at the rejected bill images and render a quick determination as to number of notes rejected for incorrect currency (country or non-accepted denomination), mutilated notes, and rejects from other causes.
  • the manufacturer may do further analysis of the contents.
  • Data from the removable storage medium 17 can be compared directly with the data that makes up the particular database. By comparing this data with the database information the manufacturer can determine precisely why a particular note was rejected. As an example, in the case of a very worn note, the data taken would in some instance be outside the acceptable limits set in the database.
  • the manufacturer may decide to take data from the rejects and incorporate it into the database, or may decide to reject expanding the acceptance of the database.
  • data from a reject would be run through the same process as in the validator, and an operator can monitor what test or tests causes the note to fail. After testing, the operator can modify the database using the new information - expanding the database to include that newest information. This allows a much wider set of good data for the database to be collected and used to develop the database. Since the user is supplying the data, no one needs to be dispatched to collect data, reducing or eliminating travel budgets to collect data.
  • a displayable image can be made at any time, permitting the operator or the manufacturer the opportunity to view high resolution, multi-spectral scans of the object. The operator can determine if the note was real or fraudulent, and adjust the failure rate accordingly. This permits a true evaluation of the performance of the validator to be made, since the operator and manufacturer now have all the data needed to make a determination.
