At least an embodiment of the present invention relates to a card reader that executes reading magnetic data recorded in a card and recording magnetic data into a card. Moreover, at least an embodiment of the present invention also relates to a card reader control method.
Conventionally, card readers for reading magnetic data recorded in a card and recording magnetic data into a card are widely used. In the industry of financial organizations and the like in which card readers are used, traditionally so-called “skimming” is a serious issue in which a criminal installs a magnetic head at a card insertion part of a card reader so as to illegally obtain magnetic data of the card by use of the magnetic head. In order to avoid such a problem, proposed is a card reader equipped with a metal sensor for detecting a magnetic head for skimming (hereinafter, called a “skimming magnetic head”) having been installed at a front side of a card insertion part (for example, refer to Patent Document 1).
In a card reader described in Patent Document 1, a metal sensor is placed inside a card insertion part that is formed as a hollow part. Meanwhile, the metal sensor includes a core made of a magnetic material, a couple of exciting coils wound on the core, and a detection coil. In the case of this card reader; at a time when the metal sensor detects a foreign object including a metallic material, a predetermined process for handling an abnormal situation is executed, so that it becomes possible to prevent a skimming magnetic head, attached at a front side of the card insertion part, from reading magnetic data.
Patent Document 1: Japanese Unexamined Patent Application Publication No. 2013-37555
A skimming method by a criminal becomes sophisticated year by year, and there happens a case in which a device for skimming, such as a skimming magnetic head (hereinafter, called a “skimming device”) for reading magnetic data of a card, is attached inside a card reader. In the case of the card reader described in Patent Document 1; though the metal sensor is able to detect a skimming device attached at the front side of the card insertion part, the metal sensor cannot detect a skimming device attached inside the card reader. Therefore, in the case of this card reader, if a skimming device is attached inside the card reader, it is impossible to prevent the skimming device from reading magnetic data. Moreover, in the case of this card reader, it is impossible to prevent the skimming device from being attached inside the card reader.
Then, at least an embodiment of the present invention provides a card reader and a card reader control method, with which it is possible to prevent a skimming device having a certain shape from being attached inside the card reader. Moreover, at least an embodiment of the present invention provides a card reader and a card reader control method, with which it is possible to prevent a skimming device, configured with an electrically-conductive material and having a certain shape, from reading magnetic data even if the skimming device is attached inside the card reader by any chance. Furthermore, at least an embodiment of the present invention provides a card reader and a control method therefor, with which it is possible to prevent a skimming device, configured with a metal and having a certain shape, from being attached inside the card reader.
In order to bring a solution for the above; a card reader according to at least an embodiment of the present invention, to be installed for use in a higher-level device, where a side with an insertion slot configured for a card is represented as a near side, and an opposite side to the near side is represented as a deep side, the card reader comprising: a card transfer path where the card inserted through the insertion slot is transferred; a card insertion detecting mechanism, placed at a deep side of the insertion slot, for detecting the card by way of switching from an OFF situation to an ON situation; a transfer roller, placed at a deeper side position than the card insertion detecting mechanism is, for transferring the card through the card transfer path; a turn detecting mechanism for detecting a turn of the transfer roller; and a card detecting mechanism, placed at a deeper side position than the transfer roller is, for detecting the card by way of switching from an OFF situation to an ON situation; wherein, if the card detecting mechanism switches from the OFF situation to the ON situation after the card insertion detecting mechanism switches from the OFF situation to the ON situation, even though no turn of the transfer roller is detected by the turn detecting mechanism, a control unit of the card reader sends a control unit of the higher-level device an alarm signal for notifying that a skimming device has been inserted through the insertion slot.
Moreover, in order to bring a solution for the subject described above; a control method for a card reader according to at least an embodiment of the present invention, to be installed for use in a higher-level device, where a side with an insertion slot configured for a card is represented as a near side, and an opposite side to the near side is represented as a deep side, the card reader comprising: a card transfer path where the card inserted through the insertion slot is transferred; a card insertion detecting mechanism, placed at a deep side of the insertion slot, for detecting the card by way of switching from an OFF situation to an ON situation; a transfer roller, placed at a deeper side position than the card insertion detecting mechanism is, for transferring the card through the card transfer path; a turn detecting mechanism for detecting a turn of the transfer roller; and a card detecting mechanism, placed at a deeper side position than the transfer roller is, for detecting the card by way of switching from an OFF situation to an ON situation; wherein, if the card detecting mechanism switches from the OFF situation to the ON situation after the card insertion detecting mechanism switches from the OFF situation to the ON situation, even though no turn of the transfer roller is detected by the turn detecting mechanism, an alarm signal for notifying that a skimming device has been inserted through the insertion slot is sent to a control unit of the higher-level device.
According to at least an embodiment of the present invention, if the card detecting mechanism switches from the OFF situation to the ON situation after the card insertion detecting mechanism switches from the OFF situation to the ON situation, even though no turn of the transfer roller is detected by the turn detecting mechanism, an alarm signal for notifying that a skimming device has been inserted through the insertion slot is sent to the control unit of the higher-level device. Therefore, according to at least an embodiment of the present invention; by way of executing a predetermined process by the control unit of the higher-level device that has received the alarm signal, it becomes possible to prevent the skimming device, having a certain shape, from being attached inside the card reader.
In other words, in the case where a normal card is inserted through the insertion slot; the card insertion detecting mechanism switches from the OFF situation to the ON situation, and then a deep side end of the card contacts the transfer roller, placed at a nearer side position than the card detecting mechanism is, so as to turn the transfer roller in such a way that, the turn detecting mechanism detects a turn of the transfer roller, and then subsequently the card detecting mechanism switches from the OFF situation to the ON situation. On the other hand, in the case where the skimming device, having a certain shape, is inserted through the insertion slot; after the card insertion detecting mechanism switches from the OFF situation to the ON situation, it may potentially happen that the card detecting mechanism switches from the OFF situation to the ON situation, without contacting the transfer roller by the skimming device.
Therefore, according to at least an embodiment of the present invention; in the case where the card detecting mechanism switches from the OFF situation to the ON situation after the card insertion detecting mechanism switches from the OFF situation to the ON situation, even though no turn of the transfer roller is detected by the turn detecting mechanism; by way of sending the control unit of the higher-level device the alarm signal for notifying that a skimming device has been inserted through the insertion slot, and moreover by way of executing a predetermined process by the control unit of the higher-level device that has received the alarm signal, it becomes possible to prevent the skimming device, having a certain shape, from being attached inside the card reader.

Moreover, in order to bring a solution for the subject described above; a control method for a card reader according to at least an embodiment of the present invention, to be installed for use in a higher-level device, where a side with an insertion slot configured for a card is represented as a near side, and an opposite side to the near side is represented as a deep side, the card reader comprising: a card insertion detecting mechanism, placed at a deep side of the insertion slot, for detecting the card by way of switching from an OFF situation to an ON situation; a first card detecting mechanism, placed at a deeper side position than the card insertion detecting mechanism is, for detecting the card by way of switching from an OFF situation to an ON situation; and a second card detecting mechanism, placed at a deeper side position than the first card detecting mechanism is, for detecting the card by way of switching from an OFF situation to an ON situation; wherein, if the second card detecting mechanism switches to the ON situation even though the first card detecting mechanism is in the OFF situation, after the card insertion detecting mechanism switches from the OFF situation to the ON situation, and before the card insertion detecting mechanism switches from the ON situation to the OFF situation, an alarm signal for notifying that a skimming device has been inserted through the insertion slot is sent to a control unit of the higher-level device.
According to at least an embodiment of the present invention, if the second card detecting mechanism switches to the ON situation even though the first card detecting mechanism is in the OFF situation, after the card insertion detecting mechanism switches from the OFF situation to the ON situation, and before the card insertion detecting mechanism switches from the ON situation to the OFF situation, an alarm signal for notifying that a skimming device has been inserted through the insertion slot is sent to the control unit of the higher-level device. Therefore, according to at least an embodiment of the present invention; by way of executing a predetermined process by the control unit of the higher-level device that has received the alarm signal, it becomes possible to prevent the skimming device, having a certain shape, from being attached inside the card reader.
In other words, in the case where a normal card is inserted through the insertion slot; there is no chance that the second card detecting mechanism has the ON situation even though the first card detecting mechanism, placed at a nearer side position than the second card detecting mechanism, is in the OFF situation, after the card insertion detecting mechanism switches from the OFF situation to the ON situation, and before the card insertion detecting mechanism switches from the ON situation to the OFF situation. On the other hand, in the case where the skimming device, having a certain shape, is inserted through the insertion slot; after the card insertion detecting mechanism switches from the OFF situation to the ON situation, it may potentially happen that the second card detecting mechanism has the ON situation even though the first card detecting mechanism is in the OFF situation, before the card insertion detecting mechanism switches from the ON situation to the OFF situation.
Therefore, according to at least an embodiment of the present invention; in the case where the second card detecting mechanism has the ON situation even though the first card detecting mechanism is in the OFF situation, after the card insertion detecting mechanism switches from the OFF situation to the ON situation, and before the card insertion detecting mechanism switches from the ON situation to the OFF situation; by way of sending the control unit of the higher-level device the alarm signal for notifying that a skimming device has been inserted through the insertion slot, and moreover by way of executing a predetermined process by the control unit of the higher-level device that has received the alarm signal, it becomes possible to prevent the skimming device, having a certain shape, from being attached inside the card reader.
Still further, in order to bring a solution for the subject described above; a card reader according to at least an embodiment of the present invention, to be installed for use in a higher-level device, the card reader comprising: an IC contact block including a plurality of IC contact springs that contact an external connection terminal of an IC chip formed in a card; and a transfer mechanism, which transfers the IC contact block between a contact-enabled position where the IC contact springs are able to contact the external connection terminal, and an evacuating position where the IC contact springs evacuate in such a way as not to contact the external connection terminal; wherein, at a time when a permission command for inserting the card into an insertion slot for the card is input from a control unit of the higher-level device, a control unit of the card reader moves the IC contact block, located at the evacuating position, to the contact-enabled position, and supplies the IC contact springs with an electric current; and then if a short circuit is detected among the plurality of IC contact springs, the control unit of the card reader sends a control unit of the higher-level device an alarm signal for notifying that a skimming device is attached inside the card reader.
Moreover, in order to bring a solution for the subject described above; a control method for a card reader according to at least an embodiment of the present invention, to be installed for use in a higher-level device, the card reader comprising: an IC contact block including a plurality of IC contact springs that contact an external connection terminal of an IC chip formed in a card; and a transfer mechanism, which transfers the IC contact block between a contact-enabled position where the IC contact springs are able to contact the external connection terminal, and an evacuating position where the IC contact springs evacuate in such a way as not to contact the external connection terminal; wherein, at a time when a permission command for inserting the card into an insertion slot for the card is input from a control unit of the higher-level device, the IC contact block, located at the evacuating position, is moved to the contact-enabled position, and the IC contact springs are supplied with an electric current; and then if a short circuit is detected among the plurality of IC contact springs, an alarm signal for notifying that a skimming device is attached inside the card reader is sent to the control unit of the higher-level device.

Therefore, according to at least an embodiment of the present invention; by way of executing a predetermined process by the control unit of the higher-level device that has received the alarm signal, it becomes possible to prevent the skimming device, configured with an electrically-conductive material and having a certain shape, from reading magnetic data even if the skimming device is attached inside the card reader by any chance.
In other words, in the case where no skimming device, configured with an electrically-conductive material and having a certain shape, is attached inside the card reader, at a time when a permission command for inserting the card into the insertion slot for the card is input from the control unit of the higher-level device, even if the IC contact block, located at the evacuating position, is moved to the contact-enabled position, and the IC contact springs are supplied with an electric current, there is no chance that any short circuit is detected among the plurality of IC contact springs. On the other hand, in the case where a skimming device, configured with an electrically-conductive material and having a certain shape, is attached inside the card reader, at a time when a permission command for inserting the card into the insertion slot for the card is input from the control unit of the higher-level device; if the IC contact block, located at the evacuating position, is moved to the contact-enabled position, and the IC contact springs are supplied with an electric current, it may potentially happen that a short circuit is detected among the plurality of IC contact springs.

Furthermore, in order to bring a solution for the subject described above; a card reader according to at least an embodiment of the present invention, to be installed for use in a higher-level device, where a side with an insertion slot configured for a card is represented as a near side, and an opposite side to the near side is represented as a deep side, the card reader comprising: a card transfer path where the card inserted through the insertion slot is transferred; a card transfer mechanism for transferring the card through the card transfer path; a card insertion detecting mechanism, placed at a deep side of the insertion slot, for detecting the card by way of switching from an OFF situation to an ON situation; and a card detecting mechanism, placed at a deeper side position than the card insertion detecting mechanism is, for detecting the card by way of switching from an OFF situation to an ON situation; wherein, a near side end of the card, transferred to a deep side position by the card transfer mechanism, is placed at a nearer side position than the card detecting mechanism is, at a time of handling the card by the card reader, if the card detecting mechanism switches from the OFF situation to the ON situation, after the card insertion detecting mechanism switches from the OFF situation to the ON situation, at a time of taking the card into the card reader, and then the card detecting mechanism switches to the OFF situation, after the card insertion detecting mechanism switches from the ON situation to the OFF situation; a control unit of the card reader makes the card transfer mechanism carry out a transfer operation toward a near side, and subsequently sends a control unit of the higher-level device an alarm signal for notifying that a skimming device has been inserted through insertion slot if the card insertion detecting mechanism keeps on having the OFF situation.
Moreover, in order to bring a solution for the subject described above; a control method for a card reader according to at least an embodiment of the present invention, to be installed for use in a higher-level device, where a side with an insertion slot configured for a card is represented as a near side, and an opposite side to the near side is represented as a deep side, the card reader comprising: a card transfer path where the card inserted through the insertion slot is transferred; a card transfer mechanism for transferring the card through the card transfer path; a card insertion detecting mechanism, placed at a deep side of the insertion slot, for detecting the card by way of switching from an OFF situation to an ON situation; and a card detecting mechanism, placed at a deeper side position than the card insertion detecting mechanism is, for detecting the card by way of switching from an OFF situation to an ON situation; wherein, a near side end of the card, transferred to a deep side position by the card transfer mechanism, is placed at a nearer side position than the card detecting mechanism is, at a time of handling the card by the card reader, if the card detecting mechanism switches from the OFF situation to the ON situation, after the card insertion detecting mechanism switches from the OFF situation to the ON situation, at a time of taking the card into the card reader, and then the card detecting mechanism switches to the OFF situation, after the card insertion detecting mechanism switches from the ON situation to the OFF situation; the card transfer mechanism carries out a transfer operation toward a near side, and subsequently an alarm signal for notifying that a skimming device has been inserted through insertion slot is sent to a control unit of the higher-level device if the card insertion detecting mechanism keeps on having the OFF situation.
According to at least an embodiment of the present invention; if the card detecting mechanism switches from the OFF situation to the ON situation, after the card insertion detecting mechanism switches from the OFF situation to the ON situation, at a time of taking the card into the card reader, and then the card detecting mechanism switches to the OFF situation, after the card insertion detecting mechanism switches from the ON situation to the OFF situation; the card transfer mechanism carries out a transfer operation toward a near side, and subsequently an alarm signal for notifying that a skimming device has been inserted through insertion slot is sent to the control unit of the higher-level device if the card insertion detecting mechanism keeps on having the OFF situation. Therefore, according to at least an embodiment of the present invention; by way of executing a predetermined process by the control unit of the higher-level device that has received the alarm signal, it becomes possible to prevent the skimming device, having a certain shape, from being attached inside the card reader.
In other words, according to at least an embodiment of the present invention, the near side end of the card, transferred to the deep side position by the card transfer mechanism, is placed at the nearer side position than the card detecting mechanism is, at the time of handling the card by the card reader; and therefore, in the case where a normal card is inserted through the insertion slot; if the card detecting mechanism switches from the OFF situation to the ON situation, after the card insertion detecting mechanism switches from the OFF situation to the ON situation, at the time of taking the card into the card reader, there is no chance that the card detecting mechanism subsequently switches to the OFF situation, after the card insertion detecting mechanism switches from the ON situation to the OFF situation. On the other hand, in the case where the skimming device, having a certain shape, is inserted through the insertion slot; if the card detecting mechanism switches from the OFF situation to the ON situation, after the card insertion detecting mechanism switches from the OFF situation to the ON situation, at the time of taking the card into the card reader, it may potentially happen that the card detecting mechanism subsequently switches to the OFF situation, after the card insertion detecting mechanism switches from the ON situation to the OFF situation. Moreover, in this case; even if the card transfer mechanism carries out a transfer operation toward a near side, it may potentially happen that the skimming device, having a certain shape, is not transferred, and the card insertion detecting mechanism keeps on having the OFF situation.
Therefore, according to at least an embodiment of the present invention; in the case where the card detecting mechanism switches from the OFF situation to the ON situation, after the card insertion detecting mechanism switches from the OFF situation to the ON situation, at the time of taking the card into the card reader, and then if the card detecting mechanism switches to the OFF situation, after the card insertion detecting mechanism switches from the ON situation to the OFF situation, the card transfer mechanism carries out a transfer operation toward a near side; and if the card insertion detecting mechanism subsequently keeps on having the OFF situation, by way of sending the control unit of the higher-level device the alarm signal for notifying that a skimming device has been inserted through insertion slot, and moreover by way of executing a predetermined process by the control unit of the higher-level device that has received the alarm signal, it becomes possible to prevent the skimming device, having a certain shape, from being attached inside the card reader.
Incidentally, for example, if a card with a special design, partially having a portion that the card detecting mechanism cannot detect, is inserted through the insertion slot, the card detecting mechanism switches from the OFF situation to the ON situation, after the card insertion detecting mechanism switches from the OFF situation to the ON situation, at the time of taking the card into the card reader; and then, it may potentially happen that the card detecting mechanism subsequently switches to the OFF situation, after the card insertion detecting mechanism switches from the ON situation to the OFF situation. Fortunately, in this case; by way of a transfer operation toward a near side by the card transfer mechanism, the card is transferred toward the near side so that the card insertion detecting mechanism switches from the OFF situation to the ON situation. Therefore, according to at least an embodiment of the present invention, it becomes possible to determine whether a card with a special design, as described above, has been inserted through the insertion slot, or a skimming device having a certain shape has been inserted through the insertion slot.
Still further, in order to bring a solution for the subject described above; a card reader according to at least an embodiment of the present invention, to be installed for use in a higher-level device, where a side with an insertion slot configured for a card is represented as a near side, and an opposite side to the near side is represented as a deep side, the card reader comprising: a card transfer path where the card inserted through the insertion slot is transferred; a card transfer mechanism for transferring the card through the card transfer path; a metal detecting mechanism, placed at a deep side position of the insertion slot, for detecting an external connection terminal of an IC chip, formed in the card, by way of switching from an OFF situation to an ON situation; and a card detecting mechanism, placed at a deeper side position than the metal detecting mechanism is, for detecting the card by way of switching from an OFF situation to an ON situation; wherein, a near side end of the card, transferred to a deep side position by the card transfer mechanism, is placed at a nearer side position than the card detecting mechanism is, at a time of handling the card by the card reader, if the metal detecting mechanism turns ON and OFF in a mode, which is different from a mode in the case where the card being a normal card, with the external connection terminal formed, is inserted through the insertion slot, at a time of taking the card into the card reader, and the card detecting mechanism switches to the OFF situation, after the card detecting mechanism switches from the OFF situation to the ON situation; a control unit of the card reader sends a control unit of the higher-level device an alarm signal for notifying that a skimming device has been inserted through the insertion slot.

According to at least an embodiment of the present invention; if the metal detecting mechanism turns ON and OFF in a mode, which is different from a mode in the case where the card being a normal card, with the external connection terminal formed, is inserted through the insertion slot, at a time of taking the card into the card reader, and the card detecting mechanism switches to the OFF situation, after the card detecting mechanism switches from the OFF situation to the ON situation; an alarm signal for notifying that a skimming device has been inserted through the insertion slot is sent to the control unit of the higher-level device. Therefore, according to at least an embodiment of the present invention; by way of executing a predetermined process by the control unit of the higher-level device that has received the alarm signal, it becomes possible to prevent the skimming device, configured with a metal and having a certain shape, from being attached inside the card reader.
In other words, according to at least an embodiment of the present invention, the near side end of the card, transferred to the deep side position by the card transfer mechanism, is placed at the nearer side position than the card detecting mechanism is, at the time of handling the card by the card reader; and therefore, in the case where a normal card is inserted through the insertion slot; at the time of taking the card into the card reader, there is no chance that the card detecting mechanism switches to the OFF situation, after the card detecting mechanism switches from the OFF situation to the ON situation. On the other hand, in the case where the skimming device, configured with a metal and having a certain shape, is inserted through the insertion slot; it may potentially happen that the metal detecting mechanism turns ON and OFF in a mode, which is different from a mode in the case where the card being a normal card, with the external connection terminal formed, is inserted through the insertion slot, at the time of taking the card into the card reader, and the card detecting mechanism switches to the OFF situation, after the card detecting mechanism switches from the OFF situation to the ON situation.
Therefore, according to at least an embodiment of the present invention; in the case where the metal detecting mechanism turns ON and OFF in a mode, which is different from a mode in the case where the card being a normal card, with the external connection terminal formed, is inserted through the insertion slot, at the time of taking the card into the card reader, and the card detecting mechanism switches to the OFF situation, after the card detecting mechanism switches from the OFF situation to the ON situation, by way of sending the control unit of the higher-level device the alarm signal for notifying that a skimming device has been inserted through insertion slot, and moreover by way of executing a predetermined process by the control unit of the higher-level device that has received the alarm signal, it becomes possible to prevent the skimming device, configured with a metal and having a certain shape, from being attached inside the card reader.
Incidentally, for example, if a card with a special design, partially having a portion that the card detecting mechanism cannot detect, is inserted through the insertion slot; at the time of taking the card into the card reader, it may potentially happen that the card detecting mechanism switches to the OFF situation, after the card detecting mechanism switches from the OFF situation to the ON situation. Fortunately, in this case; if the external connection terminal is formed at the same position in the card with a special design, as it is in the card being a normal card; the metal detecting mechanism turns ON and OFF in the same mode as a mode in the case where the card being a normal card is inserted through the insertion slot. Therefore, according to at least an embodiment of the present invention, it becomes possible to determine whether the card with a special design, in which the external connection terminal is formed at the same position as it is in the card being a normal card, has been inserted through insertion slot, or a skimming device, configured with a metal and having a certain shape, has been inserted through insertion slot.

In the meantime, each of the lever members 22 is biased with a spring member that is not illustrated in the drawings, in such a way that a lower end side of the card contacting part 22a is located within the card transfer path 7.
At a standby time before insertion of the card 2 into the insertion slot 4, the lower end side of the card contacting part 22a is located within the card transfer path 7, as shown with a solid line in
On the other hand, if the width of the card 2 inserted into the insertion slot 4 is narrower than the predetermined width so that, in at least either of the two sensors 23, the light blocking part 22b does not deviate from the space between the light emitting part and the light receiving part of each of the sensors 23, the card insertion detecting mechanism 14 keeps on the OFF situation. In this way, the card insertion detecting mechanism 14 detects the card 2, by way of switching from the OFF situation to the ON situation in the case where the width in the right-and-left direction of the card 2 inserted into the insertion slot 4 is the predetermined width. Incidentally, the card insertion detecting mechanism 14 may be in an OFF situation, while the two sets of the light blocking part 22b individually deviate from the space between the light emitting part and the light receiving part of each of the sensors 23, at a standby time before insertion of the card 2 into the insertion slot 4. In this case; if the card 2 having the width of the predetermined dimension is inserted into the insertion slot 4 so that each of the two light blocking part 22b blocks up the space between the light emitting part and the light receiving part of each of the sensors 23, the card insertion detecting mechanism 14 gets into an ON situation.
The shutter member 13 is located at either a border part between the card insertion part 5 and the main body 6, or a rear end part of the card insertion part 5. To the shutter member 13, there is connected a shutter drive mechanism 24 (refer to
The shutter member 13 is movable between a blocking position (a position shown with a chain double-dashed line in
The card detecting mechanisms 15 & 16 are placed inside the main body 6. Namely, the card detecting mechanisms 15 & 16 are placed at deeper side positions than the card insertion detecting mechanism 14 is. Moreover, the card detecting mechanism 15 and the card detecting mechanism 16 are placed in such a way that they are located at different positions displaced from each other in a front-back direction. In the present embodiment, the card detecting mechanism 16 is placed at a deeper side position than the card detecting mechanism 15 is. The card detecting mechanisms 15 & 16 are electrically connected to the control unit 17. Meanwhile, the card detecting mechanisms 15 & 16 are individually transmission optical sensors including light emitting parts 15a & 16a and light receiving parts 15b & 16b, which are positioned so as to face each other, respectively. As shown in
In the case where the card 2 does not exist between the light emitting parts 15a & 16a and the light receiving parts 15b & 16b, the light receiving parts 15b & 16b receive light coming from the light emitting parts 15a & 16a, respectively. At the time, the card detecting mechanisms 15 & 16 are in an OFF situation. If once the card 2 enters a space between the light receiving parts 15b & 16b and the light emitting parts 15a & 16a in this situation, the light coming from the light emitting parts 15a & 16a toward the light receiving parts 15b & 16b is blocked to switch the card detecting mechanisms 15 & 16 into an ON situation. In this way, the card detecting mechanisms 15 & 16 detects the card 2 by way of switching from the OFF situation to the ON situation. In the present embodiment, the card detecting mechanism 15 is a first card detecting mechanism, and meanwhile the card detecting mechanism 16 is a second card detecting mechanism.
Incidentally, the card detecting mechanisms 15 & 16 may be optical sensors of a reflective type. In this case, at a time when a light receiving part does not receive light from a light emitting part in the card detecting mechanisms 15 & 16, the card detecting mechanisms 15 & 16 are in an OFF situation. In the meantime, if the light receiving part receives the light, which is launched from the light emitting part in the card detecting mechanisms 15 & 16 and reflected by the card 2, the card insertion detecting mechanism 14 gets into the ON situation.
The card transfer mechanism 8 is provided with a transfer roller 26 that contacts the card 2 to transfer the card 2 through the card transfer path 7, a motor 28 (refer to
As shown in
The motor 28 is provided with an encoder 30 for detecting a turn of the motor 28. In the present embodiment, even in a situation where the motor 28 is in a stop state, the transfer roller 26 can be turned. If the transfer roller 26 turns in a situation where the motor 28 is in a stop state, a turn of the motor 28 is detected by the encoder 30. In other words, if the transfer roller 26 turns in a situation where the motor 28 is in a stop state, a turn of transfer roller 26 is detected by the encoder 30. The motor 28 and the encoder 30 are electrically connected to the control unit 17. The encoder 30 according to the present embodiment is a turn detecting mechanism for detecting a turn of the transfer roller 26.
(Control Method of the Card Reader)
It is presumed that, for example, the skimming device 50 shown in
The control unit 17 controls the card reader 1, as described below, at a time of taking in the card 2, in such a way that the skimming device 50 is not attached inside the card reader 1. Namely; if the higher-level device 3 executes a predetermined operation and a permission command for inserting the card 2 into the insertion slot 4 is input from the higher-level control unit 18 to the control unit 17, the control unit 17 judges at first whether or not the card insertion detecting mechanism 14 has switched from an OFF situation to an ON situation (Step S1), as shown in
At Step S2, if the take-in process cancelling command is input from the higher-level control unit 18 to the control unit 17, the take-in process for the card 2 by the card reader 1 finishes. On the other hand, at Step S2, if the take-in process cancelling command is not input from the higher-level control unit 18 to the control unit 17, operation returns to Step S1. In the meantime, if the card insertion detecting mechanism 14 switches from the OFF situation to the ON situation at Step S1, the shutter member 13 moves from the blocking position to the opening position (Step S3). Then, the control unit 17 judges whether or not the encoder 30 has detected a turn of the transfer roller 26 (Step S4).
If no turn of the transfer roller 26 has been detected at Step S4, the control unit 17 judges whether or not the card detecting mechanism 15 has switched from an OFF situation to an ON situation (Step S5). If the card detecting mechanism 15 is still in the OFF situation at Step S5, the control unit 17 judges whether or not a take-in process cancelling command to cancel a take-in process for the card 2 is input from the higher-level control unit 18 to the control unit 17 (Step S6). At Step S6, if the take-in process cancelling command is input from the higher-level control unit 18 to the control unit 17, the take-in process for the card 2 by the card reader 1 finishes. On the other hand, at Step S6, if the take-in process cancelling command is not input from the higher-level control unit 18 to the control unit 17, operation returns to Step S4.
As shown in
In the meantime, if no turn of the transfer roller 26 is detected at Step S4, and moreover the card detecting mechanism 15 switches from the OFF situation to the ON situation at Step S5 (in other words; even though the encoder 30 detects no turn of the transfer roller 26, the card detecting mechanism 15 switches from the OFF situation to the ON situation), it is presumed that the skimming device 50 is inserted through the insertion slot 4 in such a way that a deep side end of the skimming device 50 reaches the card detecting mechanism 15, as shown in
On the other hand; in the case where the card 2 being a normal card is inserted through the insertion slot 4, the deep side end of the card 2 contacts the transfer roller 26, placed at a nearer side position than the card detecting mechanism 15 is, so as to turn the transfer roller 26 in such a way that, the encoder 30 detects a turn of the transfer roller 26, and then subsequently the card detecting mechanism 15 switches from the OFF situation to the ON situation. Namely, in the case where the card 2 being a normal card is inserted through the insertion slot 4, there is no chance that the card detecting mechanism 15 switches from the OFF situation to the ON situation even though the encoder 30 detects no turn of the transfer roller 26.
Therefore, if the card detecting mechanism 15 switches from the OFF situation to the ON situation at Step 5, the control unit 17 stops the take-in process for the card 2 (Step S8), and then sends an alarm signal to the higher-level control unit 18, in order to notify that the skimming device 50 has been inserted through the insertion slot 4 (Step S9). Concretely to describe; at Step S9, the control unit 17 sends the higher-level control unit 18 an alarm signal having a high level of error, in order to notify that the skimming device 50 has been inserted through the insertion slot 4. After sending the alarm signal to the higher-level control unit 18, the take-in process for the card 2 by the card reader 1 finishes. In the meantime; the higher-level control unit 18, to which the alarm signal has been input, executes a predetermined process, such as halting the operation of the higher-level device 3, in order to prevent the skimming device 50 from being attached inside the card reader 1.
Meanwhile, if the motor 28 gets activated at Step S7 and a transfer process of the card 2 by the card transfer mechanism 8 starts, the control unit 17 judges whether or not the card insertion detecting mechanism 14 has switched from an ON situation to an OFF situation (Step S10). If the card insertion detecting mechanism 14 has switched from the ON situation to the OFF situation at Step S10, a subsequent take-in process for the card 2 continues. On the other hand; if the card insertion detecting mechanism 14 is still in the ON situation at Step S10, the control unit 17 judges whether or not the card detecting mechanism 15 is in an OFF situation and furthermore the card detecting mechanism 16 is in an ON situation (Step S11).
In the case where the both of the card detecting mechanisms 15 & 16 are in an ON situation after the transfer process of the card 2 by the card transfer mechanism 8 starts, it is presumed that the deep side end of the card 2 has already reached the card detecting mechanism 16 even though a near side end of the card 2 has not yet passed the card insertion detecting mechanism 14, as shown in
In the meantime, in the case where the card detecting mechanism 15 is in an OFF situation and the card detecting mechanism 16 is in an ON situation at Step S11 (in other words, the card detecting mechanism 16 is in an ON situation even though the card detecting mechanism 15 is in the OFF situation), it is presumed that the skimming device 50 has been inserted through the insertion slot 4, as shown in
Therefore, in the case of “Yes” as a result at Step S11, operation progresses to Step S8 so that the control unit 17 stops the take-in process for the card 2. Concretely to describe, the control unit 17 stops the motor 28 at Step S8 after Step S11. Then, subsequently operation progresses to Step S9, and the control unit 17 sends the higher-level control unit 18 an alarm signal, in order to notify that the skimming device 50 has been inserted through the insertion slot 4. Incidentally, in the case of “Yes” as a result at Step S11, it is presumed that a turn of the transfer roller 26 has been detected for some reason at Step S4, even though the skimming device 50 has been inserted through the insertion slot 4.
In this way, according to the present embodiment; if the card detecting mechanism 15 switches from the OFF situation to the ON situation after the card insertion detecting mechanism 14 switches from the OFF situation to the ON situation, even though no turn of the transfer roller 26 is detected by the encoder 30, the alarm signal for notifying that the skimming device 50 has been inserted through the insertion slot 4 is sent to the higher-level control unit 18. Moreover, according to the present embodiment; if the card detecting mechanism 16 switches to the ON situation even though the card detecting mechanism 15 is in the OFF situation, after the card insertion detecting mechanism 14 switches from the OFF situation to the ON situation, and before the card insertion detecting mechanism 14 switches from the ON situation to the OFF situation, the alarm signal for notifying that the skimming device 50 has been inserted through the insertion slot 4 is sent to the higher-level control unit 18.
Furthermore, even in the case where the skimming device 50 has been attached inside the card reader 1 by any chance, the control unit 17 controls the card reader 1 as described below, in order to prevent the skimming device 50 from reading magnetic data. Namely; if the higher-level device 3 executes a predetermined operation and a permission command for inserting the card 2 into the insertion slot 4 is input from the higher-level control unit 18 to the control unit 17, the control unit 17 moves the IC contact block 12, located at the evacuating position, to the contact-enabled position, as shown in
If the IC contact block 12 is moved to the contact-enabled position in a situation where nothing is placed inside the card reader 1, the plurality of IC contact springs 11 contact the lower guide member 20 formed of a resin material having an insulation quality. Therefore, even if the IC contact block 12 is moved to the contact-enabled position in a situation where nothing is placed inside the card reader 1, and the IC contact springs 11 are supplied with an electric current, there is no chance that any short circuit is detected among the plurality of IC contact springs 11.
In the meantime, according to the present embodiment; if the IC contact block 12 is moved to the contact-enabled position in a situation where the skimming device 50 is attached inside the card reader 1, the plurality of IC contact springs 11 contact the skimming device 50 configured with metal (refer to
Then, if no short circuit is detected among the plurality of IC contact springs 11 at Step S23, a subsequent take-in process for the card 2 continues. Concretely to describe, operation progresses to Step S1 already described. On the other hand, if a short circuit is detected at Step S23 among the plurality of IC contact springs 11, the control unit 17 sends the higher-level control unit 18 an alarm signal, in order to notify that the skimming device 50 is attached inside the card reader 1 (Step S24). Concretely to describe; at Step S24, the control unit 17 sends the higher-level control unit 18 the alarm signal having a high level of error, in order to notify that the skimming device 50 is attached inside the card reader 1. After sending the alarm signal to the higher-level control unit 18, the take-in process for the card 2 by the card reader 1 finishes. In the meantime; the higher-level control unit 18, to which the alarm signal has been input, executes a predetermined process, such as halting the operation of the higher-level device 3, in order to prevent the skimming device 50 from reading magnetic data.
In this way, according to the present embodiment; at a time when the permission command for inserting the card 2 into the insertion slot 4 is input from the higher-level control unit 18, the IC contact block 12, located at the evacuating position, is moved to the contact-enabled position, and the IC contact springs 11 are supplied with an electric current. Then, if a short circuit among the plurality of IC contact springs 11 is detected, the alarm signal for notifying that the skimming device 50 is attached inside the card reader 1 is sent to the higher-level control unit 18.
As explained above, in the present embodiment; if the card detecting mechanism 15 switches from the OFF situation to the ON situation after the card insertion detecting mechanism 14 switches from the OFF situation to the ON situation, even though no turn of the transfer roller 26 is detected by the encoder 30, the control unit 17 sends the higher-level control unit 18 the alarm signal for notifying that the skimming device 50 has been inserted through the insertion slot 4. Moreover, according to the present embodiment; if the card detecting mechanism 16 switches to the ON situation even though the card detecting mechanism 15 is in the OFF situation, after the card insertion detecting mechanism 14 switches from the OFF situation to the ON situation, and before the card insertion detecting mechanism 14 switches from the ON situation to the OFF situation, the control unit 17 sends the higher-level control unit 18 the alarm signal for notifying that the skimming device 50 has been inserted through the insertion slot 4.
In other words, according to the present embodiment; if it is presumed that the skimming device 50 has been inserted through the insertion slot 4, the control unit 17 sends the higher-level control unit 18 the alarm signal for notifying that the skimming device 50 has been inserted through the insertion slot 4, as described above. Furthermore, according to the present embodiment; if once this alarm signal is sent to the higher-level control unit 18, the take-in process for the card 2 by the card reader 1 finishes, and meanwhile, the higher-level control unit 18, to which the alarm signal has been input, executes a predetermined process, such as halting the operation of the higher-level device 3, in order to prevent the skimming device 50 from being attached inside the card reader 1. Therefore, according to the present embodiment, it becomes possible to prevent the skimming device 50, having a certain shape as shown in
In the present embodiment, at a time when a permission command for inserting the card 2 into the insertion slot 4 is input from the higher-level control unit 18, the IC contact block 12, located at the evacuating position, is moved to the contact-enabled position, and the IC contact springs 11 are supplied with an electric current. Then, if a short circuit is detected among the plurality of IC contact springs 11, the control unit 17 sends the higher-level control unit 18 the alarm signal for notifying that the skimming device 50 is attached inside the card reader 1. Namely, in the present embodiment as described above; in the case where it is presumed that the skimming device 50 is attached inside the card reader 1, the control unit 17 sends the higher-level control unit 18 the alarm signal for notifying that the skimming device 50 is attached inside the card reader 1.
Moreover, according to the present embodiment; if once the alarm signal is sent to the higher-level control unit 18, the take-in process for the card 2 by the card reader 1 finishes, and then the higher-level control unit 18, to which the alarm signal has been input, executes a predetermined process, such as halting the operation of the higher-level device 3, in order to prevent the skimming device 50 from reading magnetic data. Therefore, according to the present embodiment; it becomes possible to prevent the skimming device 50, configured with an electrically-conductive material and having a certain shape, from reading magnetic data even if the skimming device 50 is attached inside the card reader 1 by any chance.
Incidentally, according to the present embodiment; by way of modification of software of the card reader 1 having an existing hardware configuration, it becomes possible to prevent the skimming device 50 from being attached inside the card reader 1; and then even if the skimming device 50 is attached inside the card reader 1 by any chance, it becomes possible to prevent the skimming device 50 from reading magnetic data. In other words, according to the present embodiment, it becomes possible to take countermeasures against skimming, without modification of the hardware configuration of the card reader 1. As a result of that, it becomes possible in the card reader 1 to take countermeasures against skimming, in a comparatively easy manner.
(Modification 1 of Card Reader and Control Method of the Card Reader)
In the case where a near side end of the card 2, transferred to a deep side position by the card transfer mechanism 8, is placed at a nearer side position than the card detecting mechanism 15 is, at a time of handling the card 2 by the card reader 1, as shown in
Incidentally, the card reader 1 of this modification is not provided with the card detecting mechanism 16. Furthermore, in the skimming device 60 presumed to be attached inside the card reader 1, there is shaped a cutout part 60a in order to avoid contacting the transfer roller 26, and moreover there is shaped a through-hole 60b (refer to
If the higher-level device 3 executes a predetermined operation and a permission command for inserting the card 2 into the insertion slot 4 is input from the higher-level control unit 18 to the control unit 17, and the card insertion detecting mechanism 14 has switched from an OFF situation to an ON situation (Step S31), as shown in
In this modification, the near side end of the card 2, transferred up to the deepest side position, is placed at a nearer side position than the card detecting mechanism 15 is, at the time of handling the card 2 by the card reader 1. Therefore, in the case where the card 2 being a normal card is inserted through the insertion slot 4; there is no chance that the card detecting mechanism 15, which has switched from the OFF situation to the ON situation at the time of taking the card 2 into the card reader 1, switches again to the OFF situation. On the other hand, if the skimming device 60 is inserted through the insertion slot 4; the card detecting mechanism 15, which has switched from the OFF situation to the ON situation, switches again to the OFF situation, at a time of take-in to the card reader 1, as shown in
Therefore, in the case where the card detecting mechanism 15 keeps on having the ON situation at Step S35, the take-in process for the card 2 continues (Step S36), and the control unit 17 judges whether or not the card 2 has been inserted up to a deep side of the card reader 1 (Step S37). If the card 2 has been inserted up to the deep side of the card reader 1 at Step S37, the take-in process for the card 2 comes to an end as it is; and on the other hand, if the card 2 has not been inserted up to the deep side of the card reader 1 at Step S37, operation return to Step S35.
Meanwhile, if the card detecting mechanism 15 switches from the ON situation to the OFF situation at Step S35, the control unit 17 stops the take-in process for the card 2, and carries out an ejection process for the card 2 (Step S38). In other words, the control unit 17 stops the take-in process for the card 2, and makes the card transfer mechanism 8 carry out a transfer operation toward a near side, at Step S38. Then, the control unit 17 judges whether or not the card insertion detecting mechanism 14 has switched from an OFF situation to an ON situation (Step S39).
As described above, in the case where the card detecting mechanism 15 switches to the OFF situation at Step S35 because, for example, there partially exists a transparent portion in the card 2; the card transfer mechanism 8 transfers the card 2 toward a near side, by way of the ejection process for the card 2 at Step S38, and then the card insertion detecting mechanism 14 switches from the OFF situation to the ON situation. Meanwhile, in a situation where the card insertion detecting mechanism 14 has switched from the OFF situation to the ON situation, it becomes possible to pull the card 2 out of the insertion slot 4. Accordingly, if the card insertion detecting mechanism 14 switches from the OFF situation to the ON situation at Step S39, the take-in process for the card 2 finishes. Then, if once the card 2 is pulled out of the insertion slot 4, it becomes possible, for example, to continuously use the higher-level device 3.
On the other hand, in the case where the card insertion detecting mechanism 14 keeps on having the OFF situation at Step S39; it is presumed that the skimming device 60 is inserted up to an internal part of the card reader 1, as shown in
Therefore, in the case where the card insertion detecting mechanism 14 keeps on having the OFF situation at Step S39, the control unit 17 sends the higher-level control unit 18 the alarm signal for notifying that the skimming device 60 has been inserted through insertion slot 4 (Step S40). After sending the alarm signal to the higher-level control unit 18, the take-in process for the card 2 by the card reader 1 finishes. In the meantime; the higher-level control unit 18, to which the alarm signal has been input, executes a predetermined process, such as halting the operation of the higher-level device 3, in order to prevent the skimming device 60 from being attached inside the card reader 1.
Thus, according to this modification; if the card detecting mechanism 15 switches from the OFF situation to the ON situation, after the card insertion detecting mechanism 14 switches from an OFF situation to an ON situation, at the time of taking the card 2 into the card reader 1, and then the card detecting mechanism 15 switches to the OFF situation, after the card insertion detecting mechanism 14 switches from the ON situation to the OFF situation; the card transfer mechanism 8 carries out a transfer operation toward a near side, and subsequently the alarm signal for notifying that the skimming device 60 has been inserted through insertion slot 4 is sent to the higher-level control unit 18 if the card insertion detecting mechanism 14 keeps on having the OFF situation. In the meantime; the higher-level control unit 18, to which the alarm signal has been input, executes a predetermined process, such as halting the operation of the higher-level device 3, in order to prevent the skimming device 60 from being attached inside the card reader 1. Therefore, according to this modification, it becomes possible to prevent the skimming device 60, having a certain shape, from being attached inside the card reader 1.
(Modification 2 of Card Reader and Control Method of the Card Reader)
In the case where a near side end of the card 2, transferred to a deep side position by the card transfer mechanism 8, is placed at a nearer side position than the card detecting mechanism 15 is, at a time of handling the card 2 by the card reader 1, as shown in
Incidentally, the metal detecting mechanism 33 is placed, as shown with a chain double-dashed line in
According to this modification; if the metal detecting mechanism 33 turns ON and OFF in a mode, which is different from a mode in the case where the card 2 being a normal card, with the external connection terminal 2b formed, is inserted through the insertion slot 4, and the card detecting mechanism 15 switches to the OFF situation, after the card detecting mechanism 15 switches from the OFF situation to the ON situation; the control unit 17 sends the higher-level control unit 18 the alarm signal for notifying that the skimming device 60 has been inserted through insertion slot 4. Namely, in the case where a detection result is obtained with the metal detecting mechanism 33 and card detecting mechanism 15, the detection result being not expected at a time when the card 2 being a normal card, with the external connection terminal 2b configured, is inserted through the insertion slot 4; it is presumed that the skimming device 60 has been inserted through insertion slot 4. Then, the control unit 17 sends the higher-level control unit 18 the alarm signal for notifying that the skimming device 60 has been inserted through insertion slot 4.
In the meantime; the higher-level control unit 18, to which the alarm signal has been input, executes a predetermined process, such as halting the operation of the higher-level device 3, in order to prevent the skimming device 60 from being attached inside the card reader 1. Therefore, according to this modification, it becomes possible to prevent the skimming device 60, configured with a metal and having a certain shape, from being attached inside the card reader 1.
Incidentally, according to this modification; for example, if the card 2 partially including a transparent portion is inserted through insertion slot 4; after the card detecting mechanism 15 switches from an OFF situation to an ON situation, it may potentially happen that the card detecting mechanism 15 switches to the OFF. Fortunately, in this case, if the card 2 is a card with a special design in which the external connection terminal 2b is formed at the same position as it is in the card 2 being a normal card, the metal detecting mechanism 33 turns ON and OFF in the same mode as in the case where the card 2 being a normal card is inserted through insertion slot 4. Therefore, it becomes possible to determine whether the card 2 with a special design, in which the external connection terminal 2b is formed at the same position as it is in the card 2 being a normal card, has been inserted through insertion slot 4, or the skimming device 60, configured with a metal and having a certain shape, has been inserted through insertion slot 4.
Described above is an example of at least an embodiment according to the present invention. However, the present invention is not limited to the above embodiment and various variations and modifications may be made without changing the concept of the present invention.
In the embodiment described above, operation may progress to Step S7, immediately after Step S3. Moreover, in the embodiment described above, a take-in process for the card 2 being a next card may continue, immediately after Step S7. Even in these cases, it becomes possible to prevent the skimming device 50, having a certain shape as shown in
Although in the embodiments described above, the card insertion detecting mechanism 14 is a width detecting mechanism that detects the card 2 having been inserted into the insertion slot 4, by way of detecting a width of the card 2 inserted into the insertion slot 4, the card insertion detecting mechanism 14 may be a detecting mechanism that detects the card 2 having been inserted into the insertion slot 4, by way of detecting a deep side end surface of the card 2 inserted through the insertion slot 4, and may be a detecting mechanism that detects the card 2 having been inserted into the insertion slot 4, by way of detecting the magnetic stripe 2a of the card 2 inserted through the insertion slot 4. Moreover, although in the embodiments described above, the card detecting mechanisms 15 & 16 are optical sensors, the card detecting mechanisms 15 & 16 may individually be any detecting mechanism other than such an optical sensor.
Although in the embodiments described above, a turn of the transfer roller 26 is detected by the encoder 30 for detecting a turn of the motor 28, there may separately be provided a turn detecting mechanism for detecting the turn of the transfer roller 26. Moreover, although in the embodiments described above, the card 2 is a card made of polyvinyl chloride, having a thickness of about 0.7 to 0.8 mm, the card 2 may be a polyethylene terephthalate (PET) card having a thickness of about 0.18 to 0.36 mm, or a paper card having a predetermined thickness, and the like. Furthermore, although in the embodiments described above, the card reader 1 is a card reader of a card-transfer type, provided with the card transfer mechanism 8, the card reader 1 may be a manual card reader with which a user carries out reading and recording magnetic data while manually moving the card 2.
While the description above refers to particular embodiments of the present invention, it will be understood that many modifications may be made without departing from the spirit thereof. The accompanying claims are intended to cover such modifications as would fall within the true scope and spirit of the present invention.
The presently disclosed embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims, rather than the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
