More specifically, this invention relates to an electronic security device based on an optoelectronic sensing barrier aligned transversely to the passage of transaction cards and the card reader driver including such device.
2. Background Art
It is known that ATM (Automated Teller Machines) or automated transaction machines are devices that allow to perform bank transactions. For this purpose, ATMs have a plurality of means enabling to carry out transactions based on the recognition of valid cards that the user inserts in the input/output card slot.
Furthermore, it is known that permanent fraud attempts are performed by criminals who try to seize bank funds. For this purpose, thieves may run card trapping scams usually called card traps. Such card-trapping devices consists of certain elements that, when inserted in the card-in/card-out passage prevent users from retrieving their cards, which remain trapped until the thief fishes it out by means of such card-trapping device.
Currently available security devices cannot efficiently avoid this type of maneuvers or scams, or else are very complex and expensive.
This invention relates to an electronic security device based on an optoelectronic sensing barrier aligned transversely to the passage of transaction cards, and further relates to a card reader driver including such device. The device comprises an optoelectronic sensing barrier transversely aligned to card-in/card-out passage, and an electronic circuit connected to such sensing barrier and comprising one or more emergency or alarm signal outputs responsive to intrusions through the sensing barrier.
It is an object of this invention to effectively prevent criminal maneuvers with ATM cards.
An advantage of this device is that it allows to sense the area adjacent to the card input slot connected to the card-in/card-out passage of cards in an automated teller machine to detect the presence of foreign means, such as the so-called “card-trapping devices”.
A further advantage of this device is that is fully electronic and lacks mechanical elements, which substantially minimize its preventive and corrective maintenance, thus increasing the MTBF, i.e. meantime between failure.
A further advantage of this device is that is capable of detecting the presence of false input slots attached to the external front panel of the original input slot, thus increasing protection against new fraud techniques.
A further objective of this invention is to replace mechanical means with an optoelectronic barrier consisting of a plurality of transmitter-receiver elements which—transversely aligned—propagate light rays across the card-in/card-out passage.
A further advantage is the flexibility to adapt to different variants, since the transmitter/receiver means can emit either infra red or other types of light radiation. In addition, the device is suitable to include a secondary optoelectronic barrier situated beneath the movable wall panel or guillotine to detect cards trapped in the card input channel.
A further advantage of the invention is that it can include different mechanical, optical, etc. sensors on the external front panel to detect the application of false sleeves.
A further advantage of this device is that it can be easily adapted to reader drivers, enabling operation connected to a conventional width sensor or guillotine sensor which are normally built in such reader drivers.
A further advantage is that the timers (analogue & digital timers with built-in microprocessors or any combinations thereof) of the electronic circuit or unit can in the presence of certain conditions send the ATM a signal to be redirected to the network indicating the presence of a card trap device installed therein. Further, it has a relay which is operated in case of a warning signal, thus enabling local action (beeper, lighting signaling or any other deterrent method).

The present invention consists of an electronic security device for automated teller machines comprising an optoelectronic sensing machine (7) transversally aligned to a card-in/card-out passage (4), further comprising an electronic circuit (10) connected to such sensing barrier (7) and including one or more emergency or alarm signal outputs responsive to intrusions through the sensing barrier (7); the invention further relates to a card reader driver (1) including such device.
More specifically, the present electronic security devise is applicable to an automated teller machine (ATM) for the detection of foreign instruments or bodies that can be inserted in the card-in/card-out transaction passage (4). Such passage (4) is arranged between an input opening (3) situated on the external front panel and an internal operational area (6) of the device. In the intermediate area of such passage (4b) a movable wall (5) having temporary closure can be provided to operate as a guillotine-type device.
The ATM card reader driver (1) comprises a card-in/card-out passage (4) extending between an input opening (3) situated on the external front panel and an internal operational area (6).
In an intermediate area (4b) situated between the input opening (3) and the internal operational area (6) there is a movable wall (5) which moves upwards and downwards like a guillotine type-cutter, temporarily blocking such input/output passage.
In the preceding area (4a) of the input/output passage (4) there is an optoelectronic sensing barrier (7) aligned transversely to such passage (4). This optoelectronic sensing barrier (7) comprises a plurality of light transmitter/receiver devices which, relative to the passage (4), are transversely aligned on both opposite sides thereof. Thus, the light rays emitted by these transmitter means propagate along the input/output passage (4) until reaching the receiver means.
In different embodiments of the invention, the light emitted can be light of the visible spectrum, ultraviolet light, infra red light, etc. Transmitters can be light emitting diodes, incandescent lamps, fluorescent lamps or other light-emitting source. Light receivers can be photo diodes, photo transistors, LDR, photo voltaic cells or other light-sensitive element.
Furthermore, the embodiments contemplate the inclusion of sensing means on the external front panel (9) of the card reader driver (1), capable of detecting the attachment of false external front panels carrying card-trapping elements.
In other embodiment of the invention the arrangement of a secondary optoelectronic barrier (8) is provided which is positioned intermediate the movable wall panel (5) and the internal operational area (6).
Furthermore, the present device comprises an electronic circuit (10) which processes the signals from the sensing barrier (7) and which is capable of generating alarm signals (18).
Such electronic circuit comprises a comparator stage, a timer stage and an alarm-cycle generator (18). Thus, in this exemplary embodiment of the invention the electronic circuit (10) comprises a first combination comparator and second combinational comparator (13) (17), a first timer, a second timer and third timer (14) (15) (16) and one alarm-cycle generator (18).
When an object is inserted in the input opening (3) of the card reader driver (1), such object intercepts one or more light beams of the optoelectronic barrier (7) which operates as a scanner of such input opening (3).
If the cut-off of light is total (the entire light beams are intercepted), it may be a valid card or a card-trapping device the width of which covers the full input opening area (3).
A valid card does not remain in this position for more than a few seconds since the card reader driver (1) pulls the card to read it inside (6) (the same occurs if the user forgets to take his/her card from the card reader driver (1). If the cut-off continues for more than the preset time, the object is a card trap device and an alarm cycle is triggered.
If the cut-off of the optoelectronic barrier (7) is partial, the object cannot be a card; if the same remains inserted for an additional set time it is a card-trapping device and an the alarm cycle is triggered (18).
The width sensor signal (11) is used to certify the presence of an element having a similar width range to a real card.
The open signal of the movable wall (guillotine is open), together with the partial cut-off of the barrier (7) triggers the alarm cycle (18).
The open signal of the movable wall, together with the total cut-off of the barrier (7) generates an additional interval cycle (waiting for an additional time frame) and after the interval cycle lapses the alarm process restarts.
If the movable wall (5) remains open, the cut-off of the barrier beams (7) is total and the secondary barrier (8) beneath the movable wall (5) is disrupted, indicating the presence of a card trapped in the input slot (4) of the card reader (1), and generating no alarm signal.
The system can be used as a trapping-device detector in deposit boxes and cash dispensers.
The primary optoelectronic barrier (7) propagates the signals of infra red beams to the electronic circuit (10).
The mechanical or primary sensing devices (9) refract their respective signals (9a) to the electronic circuit (10).
The width sensor (11) propagates the signal (11a) to the electronic circuit (10).
The guillotine sensor (12) of the movable wall or guillotine-type device (5) propagates the signal (12a) to the electronic circuit (10).
The secondary optical barrier (8) beneath the movable wall (5) propagates the signal (8a) to the electronic circuit (10).
The electronic circuit (10) sends the alarm signal to the ATM machine.
The electronic circuit (10) activates the relay (31) in case of detecting a card trapping device (external warning).
The function of the primary barrier (7) is to detect either total or partial disruption or alteration of one or more of its beams (including that of transparent objects in the primary area (4a) of the passage (4), in adjacent sides of the input opening (3) of the front panel (2).
The function of the width sensor (11) is to detect the entry or presence within the passage (4) of an object having a similar width to a valid card. This sensing device is an electromechanical sensor (e.g. micro switch) which is operated by the side pressure applied by the card in the passage 84).
The function of the guillotine sensor (12) is to detect the position of the movable wall or guillotine-type device (5) [close is normal mode, open is alert mode]. This sensing device is an electromechanical sensor [e.g. micro switch] which is operated according to the position of the movable wall 85).
The secondary barrier (8) operates as a trapped/stuck card sensor when it detects the presence of a trapped card [due to deformation or other cause] inside the input passage (4).
The function of the front or primary sensors or detectors (9) is to detect the presence of a “false” sleeve with a card trap that a scammer intentionally attaches over the ATM slot front (2) of the card reader driver (1). These sensing devices can be one or more mechanical sensors and are installed on the external front (2) panel; and are operated by the pressure applied over the sleeve attached to the front panel (2) of the card reader (1). In a further variant one or more light sensors can be installed in the front panel (2) of the card reader (1). These receivers sense the light variation [darkening on the original front (2)], which occurs when a false front or sleeve is installed.
This device can be added to existing card reader drivers (1) or else, new card reader units (1) can be manufactured with this new device.
