TECHNICAL FIELD [001] The present invention relates to a device used to detect fraud at ATMs, also known as ATMs. More particularly, the present invention relates to a device for detecting fraud by obstructing a banknote dispenser (CD) at self-service terminals (ATM).

DESCRIPTION OF THE STATE OF THE TECHNIQUE [002] With the growing demand for products and services, automated devices are increasingly being developed to meet the needs of society. In general, automated devices are devices capable of verifying and controlling their own functioning, making measurements and introducing corrections, without the need for constant human interference.

[003] An example of an automated device is the self-service terminals. Self-service terminals are able to deal directly with a customer without the need for an employee or an establishment to broker an operation, which dramatically decreases the operating costs of a business as a whole.

[004] Self-service terminals (ATM, Automated)

Teller Machine), also known as ATMs, provide a variety of service options for a financial institution. Users of such terminals can perform financial transfers, balance inquiries, withdrawals, bill payments, without having to go through a bank teller. In general, ATMs are located inside bank branches, shopping malls, gas stations and establishments in general,

Petition 870160079495, of 12/27/2016, p. 10/24/10 or outside kiosks located at strategic points on the streets. [005] Generally, self-service terminals have a safe where cash is stored. In addition, as self-service terminals need to exchange cash with a user, there is an opening in the terminal for a user to deposit envelopes containing bank note, checks or other documents. This opening is generally configured as a horizontal passage, defining an access tunnel, and which, in the innermost part of the terminal, has a mechanism to transport envelopes or bank notes between this opening and the safe. [006] Subsequently, a self-service terminal operator can access the interior of the safe or deposit through a door in the safe, using a physical or electronic key, and collect the deposited envelopes as well as supply the safe with banknote cash at this payment terminal. self service.

[007] Thus, it is not possible for a user to access or remove any cash from stored banknotes or envelopes previously deposited at the terminal, either with their hands or with any device. Access to bank note cash or envelope deposits is only possible by opening an ATM with an authorized operator.

[008] However, self-service terminals have been the target of fraud in order to steal information from users' cards or steal bank notes stored in terminals.

[009] There are techniques applied by malicious people to obstruct the flow of an envelope inserted at the entrance of the self-service terminal, so that it would be possible to defraud the normal operation of the self-service terminal. Such a technique consists of using a screen, such as a tray, which is positioned inside the access tunnel of the ATM. The bulkhead is designed to block

Petition 870160079495, of 12/27/2016, p. 11/24 / 10 the passage of any envelope or user document to the terminal vault, when it is already inserted at the entrance of the self-service terminal. In addition, such a screen is designed so that, when inserted into the access tunnel of the ATM, its presence is not noticeable to a user who wants to insert an envelope in the terminal.

[0010] Thus, when a user inserts an envelope in the fraudulent ATM, the envelope or document is retained by the tray and is not effectively deposited in the ATM of the ATM. In addition, the envelope cannot be removed from the terminal by the user himself, since the envelope or document is retained inside the access tunnel of the ATM, which is inaccessible to the user.

[0011] The self-service terminal does not have a mechanism to detect whether an envelope has actually reached the self-service terminal deposit. Detection usually takes place at the entrance of the tunnel that receives the document, so the envelope is retained by the fraudulent device after this detection. Thus, after inserting an envelope, the user often does not even know of the occurrence of a violation, ends the operation at the self-service terminal and leaves the place. Subsequently, the offender returns to the location of the ATM and, with the aid of a suitable device, such as a hook, removes a fraudulent device from the interior of the access tunnel of the ATM. Upon removing the fraudulent device, the infringer will have access to all deposited envelopes that have been retained at the ATM. The practice of this fraud is commonly known as "Fisheries fraud".

[0012] In addition to the “Fisheries fraud” there is another type of fraud applied by malicious people to obstruct the exit of banknote cash by gluing a ruler over the exit opening,

Petition 870160079495, of 12/27/2016, p. 12/24 / 10 preventing the banknotes from being presented to the customer and this same ruler captures this cash so that these malicious people can subtract this cash from the operator of the ATM or the customer, by removing the ruler with the cash banknotes captured by the ruler, this type of fraud is known as the “ruler's coup”.

These frauds cause a lot of inconvenience in the operation of the self-service terminals, since the terminal's operation is usually interrupted until the identification of the occurrence of the fraud. In addition, the owner of the self-service terminal is often obliged to take responsibility for the damages and, in the case of lost money, return the amount to the user, even without being sure of the fraud that has occurred.

[0013] Therefore, the self-service terminals need to be equipped with a device for detecting such fraudulent devices, so that an operator of the self-service terminal is notified of the presence of a fraudulent device and can go to the terminal location to remove fraud or, at least, interrupt the operation of the terminal until the necessary repairs are carried out.

[0014] The current state of the art comprises some devices to prevent fraud at ATMs. For example, document BR 102013021681 A2 features a nozzle reinforcement device for the banknote dispenser to make nozzle tampering difficult and prevent the introduction of explosives into self-service equipment.

[0015] For conventional equipment, there are currently physical or mechanical scanning sensors for the detection of foreign objects inserted in the region of the banknote exit nozzle. However, such physical sensors are relatively costly to install and require allocation of considerable space inside the ATM. In addition, mechanical sensors have natural wear due to movements

Petition 870160079495, of 12/27/2016, p. 13/24 / 10 repetitive, which requires regular maintenance.

[0016] Alternatively, conventional terminals have sensors for the detection of proximity or obstruction of the passage of light. These, despite containing essentially electronic components, are sensitive to external light variation, since this can influence the detection of sensors [0017] When using a light detection sensor, it should be considered that the self-service terminals are exposed to a variety of lighting situations, whether caused by the variation of solar natural lighting throughout the day or by the diversity of conditions existing in the artificial lighting of the environments in which the terminals are installed, causing interference in the operation of light detection sensors .

[0018] The main characteristics of light sources, whether natural or artificial, refer to the wide range of the spectrum that the sources fall under, such as sunlight, for example, which may have components ranging from infrared radiation, light visible, ultraviolet, among others, as well as vary its intensity in dark and low-light environments or in fully lit environments with a profusion of light sources. In addition, light sources can have other characteristics, such as fluorescent lamps that flash at a rate of 120 Hz, imperceptible to the naked eye, but detectable with the use of light sensors.

[0019] Thus, there is a need for a system capable of detecting the presence of an unauthorized object positioned in the access tunnel of the ATM or superimposed on the entrance nozzle, in order to prevent the occurrence of cash retention fraud. banknotes, or the loss of envelopes or documents inserted in the ATM.

[0020] Additionally, there is a need for a system capable of detecting the presence of an unauthorized object, which is robust and does not suffer interference from the environment outside the ATM, in particular,

Petition 870160079495, of 12/27/2016, p. 14/24 / 10 light variations due to external, natural or artificial light sources. [0021] The present invention proposes to remedy inconveniences of the previous techniques allowing to guarantee the non-violation of the banknote dispensers of the self-service terminals as well as deposits of envelopes and documents.

OBJECTIVES OF THE INVENTION [0022] The present invention comprises at least one device to prevent the violation of the banknote dispenser (CD) of the self-service terminals (ATM) with the use of reflective sensor and that overcomes the problems mentioned above, so that foreign objects overlapping the exit nozzles of the ballot dispensers are identified.

[0023] The objective of the present invention is to provide an efficient security device for self-service terminals (ATM) banknote (CD) dispensers, also known as ATMs, allowing foreign objects to be superimposed on the outlet nozzles. banknote dispensers are detected.

BRIEF DESCRIPTION OF THE INVENTION [0024] In order to achieve the objectives described above, the present invention provides a safety device consisting of at least one integrated reflective sensor that has its own light source and a photodetector on the same printed circuit board , causing the photodetector to respond only to the light source itself integrated into the plate. As the target of the detection of the reflective sensor will be in its frontal region, the present invention also has at least one mask used as a light driver and a compensation circuit to adjust the light emitted by the light source itself.

DETAILED DESCRIPTION OF THE INVENTION [0026] The description which follows will start from a preferred embodiment of the invention. As will be apparent to any person skilled in the art, however, the invention is not limited to that particular embodiment.

[0027] Figure 1 shows an example of a printed circuit board 30 with three pairs of sensors 20 of a security device 10 of the present invention.

[0028] The approximate dimensions of the safety device 10 are:

- length and width of the printed circuit board (30): 112 x 18.5 mm;

- mask thickness (31): 3.8 mm;

- protective film thickness (32): 0.5 mm (the protective film is made of a material that does not influence the luminous flux between the emitter and receiver).

[0029] Figure 2 shows a security device 10 composed of

Petition 870160079495, of 12/27/2016, p. 16/24 / 10 by three layers (printed circuit board 30, mask 31 and protective film 32), and has at least one integrated reflective sensor 20 that has its own light source 21 and a photodetector 22 on the same plate. printed circuit 30 (in order to eliminate the influence of external light that can assume different shapes, intensities and directions), making the photodetector 22 respond only to the light emitted by the own light source 21 integrated in the plate 30. As the target of the detection of the reflective sensor 20 is in its frontal region, the present invention also has at least one mask 31 to limit the light of the own light source 21 only to its frontal portion.

[0030] Specifically, in figure 2, there are three sensors 20, that is, a pair consisting of an infrared led light emitter 21 and, next to it, a receiver 22. The receiver 22 receives reflections from the lights emitted by the emitter. light 21 and also by other lights that sensitize it (external lights), however, the light emitted by the emitter 21 is modulated by a compensation circuit 40 connected to the receiver 22, including an amplifier of the signals in the specific range of the light emitted by the emitter light 21, filtering or severely attenuating other signals.

[0031] Thus, the light source 21 emits a light with a specific modulation, which can vary between 38kHz to 56kHz, the source 21 in line with a compensation circuit 40 to ensure that the detection by the photodetector 22 is correct, where the photodetector 22 will respond only to this specific modulation. This specific modulation of the light emitted by the own light source 21 is determined by the compensation circuit 40 that regulates the modulation of the light emitted by the own source 21 so that the photodetector 22 detects only that light, even in environments with direct sunlight or other external sources of lighting. The compensation circuit 40 adjusts the working point of the integrated reflective sensor 20 of the present invention, reducing and / or eliminating the response of the photodetector 22 to continuous light signals (external light), increasing the response to modulated light signals

Petition 870160079495, of 12/27/2016, p. 17/24 / 10 emitted by the light source integrated into the printed circuit board 30. [0032] Figure 3 shows a front view of the safety device

10. In the device in figure 3, there are four pairs of sensors 20, where the transparent crystal component, on the left, is an infrared light emitting led 21, and the component on its right is the infrared receiver 22 (in black) which includes a compensation circuit 40, composed of an amplification and filtering circuit of the light signals generated in the emitter 21 that are in the range of 38kHz to 56kHz.

[0033] As the target of the detection of the reflective sensor is in its frontal region, the present invention has a mask 31 used to direct the light to the frontal region of the sensor avoiding that any light leaks from the sides can directly reach the receiver In this way, only the frontal reflections of the possible objects superimposed on the exit nozzles of the banknote dispensers used for fraud will reach the infrared receiver 22.

[001] Figure 4 presents an overview of the various components of the compensation circuit 40, including an integrated circuit for modulating the light source itself (21) and evaluating the signal generated by the photodetector (22) to determine the presence or absence of objects overlapping the outlet nozzles.

[002] Figure 5 shows a mask 31 for the safety device 10 with capacity for four pairs of sensors 20.

[003] In a preferred embodiment of the present invention, the safety device 10 has two or more individual reflective sensors 20 mounted on the same printed circuit board 30, so that their respective mechanical light drivers, mask 31, block the light characteristic of the other sensors so as not to compromise the correct functioning of each sensor individually, causing the photodetectors 22 of each sensor to respond only to frontal signals.

Petition 870160079495, of 12/27/2016, p. 18/24 / 10 [004] The use of two or more individual reflective sensors 20 on a printed circuit board 30 has the advantage of increasing the area of coverage of the exit nozzle area of the bill dispensers.

[005] Numerous variations affecting the scope of protection of this application are permitted. Thus, it reinforces the fact that the present invention is not limited to the particular configurations / embodiments described above.
