I - BACKGROUND OF THE INVENTION
TECHNICAL FIELD
[0001] This invention relates to the field of banking security. Specifically, this invention
relates to automated teller machines.
[0002] More specifically, this invention relates to an electronic security device based
on an optoeledronic sensing barrier aligned transversely to the passage of transaction
cards and a card reader driver including such device.
BACKGROUND ART
[0003] 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.
[0004] 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.
[0005] Currently available security devices cannot efficiently avoid this type of maneuvers
or scams, or else are very complex and expensive.
II - SUMMARY OF THE INVENTION
[0006] 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 a 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.
DISCLOSURE OF INVENTION
[0007] It is an object of this invention to effectively prevent criminal maneuvers with
ATM cards.
[0008] 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".
[0009] 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.
[0010] 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.
[0011] A further objective of this invention is to replace mechanical means with an optoelectronic
barrier consisting of a plurality of transmitterreceiver elements which -transversely
aligned- propagate light rays across the card-in/card-out passage.
[0012] 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.
[0013] 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.
[0014] 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.
[0015] 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).

IV- DETAILED DESCRIPTION
[0019] 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 passing through the sensing barrier (7); the invention further relates
to a
card reader driver (1) including such device.
[0020] 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.
[0021] 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).
[0022] 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.
[0023] 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.
[0024] 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.
[0025] 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.
[0026] 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).
[0027] 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).
[0028] 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 combinational 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).
OPERATION
[0029] 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).
[0030] 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).
[0031] 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.
[0032] 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).
[0033] The width sensor signal (11) is used to certify the presence of an element having
a similar width range to a real card.
[0034] The open signal of the movable wall (the guillotine is open), together with the partial
cut-off of the barrier (7) trigger the alarm cycle (18).
[0035] The open signal of the movable wall, together with the total cut-off of the barrier
(7) generate an additional interval cycle (waiting for an additional time frame) and
after the interval cycle lapses the alarm process restarts.
[0036] 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.
[0037] The system can be used as a trapping-device detector in deposit boxes and cash dispensers.
[0038] 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).
[0039] The width sensor (11) propagates the signal (11a) to the electronic circuit (10).
[0040] The guillotine sensor (12) of the movable wall or guillotine-type device (5) propagates
the signal (12a) to the electronic circuit (10).
[0041] The secondary optical barrier (8) beneath the movable wall (5) propagates the signal
(8a) to the electronic circuit (10).
[0042] The electronic circuit (10) sends the alarm signal to the ATM machine.
[0043] The electronic circuit (10) activates the relay (31) in case of detecting a card
trapping device (external warning).
[0044] 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 the adjacent sides of the input opening
(3) of the front panel (2).
[0045] 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 (4).
[0046] 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 (5).
[0047] 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)
[0048] 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.
[0049] 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.
