<2. About skimming>
By the way, a crime called skimming that illegally obtains customer information recorded on a customer transaction card (cash card or the like) as a recording medium has occurred. Skimming is a criminal act of recording customer information obtained illegally on a counterfeit card and withdrawing cash from the customer account with the counterfeit card. The skimming is performed, for example, by attaching a skimming device, which is an unauthorized reading device, in the vicinity of the card insertion portion 16 of the automatic transaction device 10 and illegally reading information recorded on a transaction card inserted by a customer.

  Therefore, the automatic transaction apparatus 10 according to the present embodiment employs a detection configuration as described below in order to more appropriately detect the skimming apparatus attached in the vicinity of the card insertion unit 16.

<3. Detection configuration of skimming device>
An example of the detection configuration of the skimming device according to the embodiment will be described with reference to FIGS. FIG. 2 is a conceptual diagram for explaining an example of the detection configuration of the skimming device of the automatic transaction device 10. FIG. 3 is a schematic diagram for explaining a detailed configuration of the card insertion portion 16. FIG. 4 is a schematic diagram for explaining a first area through which a transaction card passes and a second area through which no transaction card passes. In FIG. 4A, the skimming device 200 is not attached, and in FIG. 4B, the skimming device 200 is attached.

  As shown in FIGS. 2 and 3, the automatic transaction apparatus 10 includes a cart reader 102, a transmission coil 104, a reception coil 106, and a comparison coil 108. Note that the transmission coil 104, the reception coil 106, and the comparison coil 108 are provided on the decorative plate 101 (FIG. 3) located in front of the card reader 102.

  The card reader 102 is a device that is provided inside the automatic transaction apparatus 10 and reads information recorded on a transaction card inserted into the card insertion slot 16a. The card reader 102 has a function of writing information on a transaction card.

  The transmission coil 104 is positioned obliquely above the card reader 102 as shown in FIG. 2, and generates a magnetic field when a current flows through the coil. As shown in FIG. 4A, the transmission coil 104 includes a first area R1 through which a transaction card inserted into the card insertion slot 16a passes and a second area through which the transaction card inserted into the card insertion slot 16a does not pass. A magnetic field is generated in each of R2. Here, as shown in FIG. 4B, the first region R1 is a region where the skimming device 200 is attached, and the second region R2 is a region where the skimming device 200 is not attached. The transmitting coil 104 is provided at a position where the generated magnetic field does not affect the card reader 102.

  The transmission coil 104 is connected to the oscillation circuit 112 as shown in FIG. The oscillation circuit 112 oscillates a high frequency current, for example. When the high-frequency current oscillated by the oscillation circuit 112 flows through the transmission coil 104, a magnetic field is generated from the center of the transmission coil 104. Therefore, in the present embodiment, the oscillation circuit 112 and the transmission coil 104 correspond to a magnetic field generation unit that generates a magnetic field.

  The reception coil 106 and the transmission coil 104 are provided obliquely below the card reader 102 so as to sandwich the first region R1. The reception coil 106 is opposed to the transmission coil 104 and detects a magnetic field generated by the transmission coil 104 in the first region R1. The receiving coil 106 generates a current (first current) corresponding to the magnetic field detected in the first region R1.

  The comparison coil 108 is provided so as to sandwich the second region R2 together with the transmission coil 104. The comparison coil 108 faces the transmission coil 104 and detects the magnetic field generated by the transmission coil 104 in the second region R2. The comparison coil 108 generates a current (second current) corresponding to the magnetic field detected in the second region R2.

  Moreover, in this embodiment, the transmission coil 104 and the reception coil 106 cooperate as a 1st detection member which detects the condition in 1st area | region R1 which passes before a transaction card is inserted in the card insertion slot 16a. Function. Moreover, the transmission coil 104 and the comparison coil 108 work together as a second detection member that detects a situation in the second region R2 that does not pass when the transaction card is inserted into the card insertion slot 16a.

  By the way, the skimming apparatus 200 includes a circuit, a substrate, and the like (metal member) for reading information recorded on a magnetic stripe or IC chip of a transaction card. The skimming device 200 can be attached to the first region R1. For this reason, the magnetic field detected by the receiving coil 106 in the first region R1 when the skimming device 200 is attached to the first region R1 is detected when the skimming device 200 is not attached to the first region R1. Different from the magnetic field. On the other hand, since the skimming device 200 is not attached to the second region R2, the magnetic field detected by the comparison coil 108 in the second region R2 does not change. Therefore, the skimming device 200 is attached to the first region R1 by comparing the magnetic field detected by the receiving coil 106 in the first region R1 with the magnetic field detected by the comparison coil 108 in the second region R2. It can be determined whether or not.

  The automatic transaction apparatus 10 further includes rectifier circuits 114 and 116, a comparison circuit 118, a control unit 120, and a detection sensor 122, as shown in FIG.

  The rectifier circuit 114 converts the high-frequency current generated by the receiving coil 106 into a direct current. Similarly, the rectifier circuit 116 converts the high-frequency current generated by the comparison coil 108 into a direct current. Then, the rectifier circuit 114 and the rectifier circuit 116 each output the converted direct current to the comparison circuit 118.

  The comparison circuit 118 compares the direct current input from the rectifier circuits 114 and 116 and detects the difference between the currents. The comparison circuit 118 includes current detection circuits 118a and 118b and a difference detection circuit 118c.

  The current detection circuit 118a detects the magnitude of the direct current input from the rectifier circuit 114. Similarly, the current detection circuit 118b detects the magnitude of the direct current input from the rectification circuit 116. The difference detection circuit 118c detects the difference between the direct current detected by the current detection circuit 118a and the direct current detected by the current detection circuit 118b. The difference detection circuit 118c outputs information about the detected difference to the control unit 120.

  The control unit 120 compares the detection result of the first detection member (the transmission coil 104 and the reception coil 106) with the detection result of the second detection member (the transmission coil 104 and the comparison coil 108), and adds in the first region R1. It has the function of the determination part which determines the presence or absence of the skimming apparatus 200 (metal member) which is a thing.

(Specific Detection Method of Skimming Device 200)
The control unit 120 determines the presence or absence of the skimming device 200 in the first region R1 based on the difference between the first current and the second current output from the difference detection circuit 118c of the comparison circuit 118. Specifically, when the difference between the first current and the second current is equal to or less than a predetermined value, the control unit 120 determines that the skimming device 200 is not attached to the first region R1, and the first current and the second current When the difference between the two currents is not less than or equal to the predetermined value, it is determined that the skimming device 200 is attached to the first region R1.

  In the present embodiment, as shown in FIG. 2, the size of the receiving coil 106 is the same as the size of the comparison coil 108. Further, the distance between the reception coil 106 and the transmission coil 104 is the same as the distance between the comparison coil 108 and the transmission coil 104. Therefore, when the skimming device 200 is not attached to the first region R1, the magnitude of the first current generated by the receiving coil 106 is the same as the magnitude of the second current generated by the comparison coil 108. Therefore, the control unit 120 determines that the skimming device 200 is not attached when the current difference is 0, and determines that the skimming device 200 is attached when there is a current difference.

  Note that the size of the receiving coil 106 may be different from the size of the comparison coil 108. Further, the distance between the reception coil 106 and the transmission coil 104 may be different from the distance between the comparison coil 108 and the transmission coil 104. In such a case, the difference (predetermined value) between the first current and the second current when the skimming device 200 is not attached to the first region R1 is stored in the storage unit in advance, and the difference detected thereafter is When it deviates from the predetermined value, it is determined that the skimming device 200 is attached.

  If it is determined that the skimming device 200 is present in the first region R1, the control unit 120 stops the transaction until the skimming device 200 is removed. Thereby, after that, customer information can be prevented from being illegally read by the skimming apparatus 200. In addition, the control unit 120 may transmit information (alarm) indicating that the skimming device 200 is present in the first region R1 to the host system (for example, the financial institution host 40). As a result, it is possible for the host system side to promptly respond thereafter.

  The control unit 120 controls the oscillation timing of the high-frequency current of the oscillation circuit 112 (in other words, the generation timing of the magnetic field by the transmission coil 104). Specifically, the control unit 120 does not oscillate the oscillation circuit 112 when the transaction card is inserted into the card insertion slot 16a and when the transaction card is removed from the card insertion slot 16a, and the first region R1. Does not generate a magnetic field. Thereby, when a transaction card is inserted or removed, it is possible to prevent the magnetic stripe of the transaction card from being destroyed by a magnetic field.

(Control of detection timing)
In addition, the control unit 120 detects the detection timing of the first detection member (the transmission coil 104 and the reception coil 106) and the second detection member (the transmission coil 104 and the comparison coil 108) according to the detection result of the customer by the detection sensor 122. To control. Here, the detection sensor 122 is connected to the control unit 120 and is a detection member that detects an operator (customer) located around the automatic transaction apparatus 10. When the detection sensor 122 detects the operator, the control unit 120 does not detect the first detection member and the second detection member, and when the detection sensor 122 does not detect the operator, The detection member and the second detection member are detected. Thereby, since it can prevent that a magnetic field generate | occur | produces during operation (for example, insertion operation of a transaction card) by an operator, the exposure by the electromagnetic waves to an operator can be suppressed.

  Moreover, the control part 120 makes a 1st detection member and a said 2nd detection member detect before the start of the transaction of the automatic transaction apparatus 10, or after completion | finish of transaction. Note that before the start of the transaction is a timing after the operator is detected by the detection sensor 122 and before the operator performs an operation on the customer operation display unit 12. Thereby, when the possibility that the skimming device 200 is attached is high, the detection by the first detection member and the second detection member is performed, so that the skimming device 200 can be detected quickly.

(Image storage when the skimming device 200 is detected)
By the way, in a financial institution or the like in which the automatic transaction apparatus 10 is set, an automatic transaction apparatus 10 and an imaging device such as a monitoring camera that images the surroundings are installed. The moving image captured by the imaging device is stored in a predetermined system (for example, the financial institution host 40).

  In the present embodiment, the control unit 120 is captured before the timing when it is determined that the first region R1 has the skimming device 200 in the moving image in which the imaging device captures the periphery of the automatic transaction apparatus 10. The image is stored in the storage unit (for example, the storage unit of the financial institution host 40 in FIG. 1). Specifically, the financial institution host 40 transmits the timing information determined that the skimming device 200 is present in the first region R1 to the financial institution host 40, so that the financial institution host 40 is set to a predetermined timing from the moving image. The captured image is extracted and stored. Accordingly, it is possible to identify the person to whom the skimming device 200 is attached by looking at the image extracted from the moving image.

  Note that the image may be stored in the storage unit of the automatic transaction apparatus 10 instead of the storage unit of the financial institution host 40. The moving image may be captured by a camera provided in the automatic transaction apparatus 10 instead of the monitoring camera.

(Display on the customer operation display)
When it is determined that the skimming device 200 is present in the first region R1, the control unit 120 causes the customer operation display unit 12 to display the determination result. Thereby, the customer can prevent inserting a transaction card in the automatic transaction apparatus 10 to which the skimming apparatus 200 is attached by looking at the determination result displayed on the customer operation display unit 12. In the present embodiment, the customer operation display unit 12 corresponds to a notification unit that notifies the determination result.

  FIG. 5 is a diagram illustrating an example of display contents of the customer operation display unit 12 when the skimming device 200 is detected. When it is determined that the skimming device 200 is present in the first region R1, the customer operation display unit 12 displays a message that calls attention regarding the insertion of the transaction card into the card insertion slot 16a as shown in FIG. . Thereby, insertion of the transaction card into the card insertion slot 16a to which the skimming device 200 is attached can be effectively prevented.

  FIG. 6 is a diagram illustrating an example of display contents of the customer operation display unit 12 when the skimming device 200 is detected. When it is determined that the skimming device 200 is present in the first region R1, the customer operation display unit 12 displays a message regarding the transaction suspension of the automatic transaction device 10 as shown in FIG. Thereby, the customer can perceive that the transaction has been stopped with the installation of the skimming device 200.

  The content displayed by the customer operation display unit 12 is not limited to the above. For example, when it is determined that the skimming device 200 is present in the first region R1, the customer operation display unit 12 displays a message such as “Please check the card insertion slot 16a” and the card insertion slot to the customer. Confirmation around 16a may be prompted.

(Modification)
In the above description, one transmission coil 104 is provided, but the present invention is not limited to this. For example, a first transmission coil that generates a magnetic field in the first region R1 and a second transmission coil that generates a magnetic field in the second region R2 may be provided separately. Thereby, for example, the second transmission coil may be provided so that the comparison coil 108 is disposed above or below the reception coil 106.

  In the above description, it is determined whether or not the skimming device 200 is attached to the first region R1 by detecting the magnetic field using the transmission coil 104, the reception coil 106, and the comparison coil 108. However, the present invention is not limited to this. . For example, an electrode may be provided instead of the coil. In such a case, it is possible to determine whether or not the skimming device 200 is attached to the first region R1 by comparing the change in the space capacitance between the electrodes in the first region R1 and the second region R2.

  In the above description, the first detection member and the second detection member are detected based on the detection result of the detection sensor 122 and the like, but the present invention is not limited to this. For example, the customer may start detection of the first detection member and the second detection member by operating on the transaction screen of the customer operation display unit 12 (for example, pressing a detection start button).

  In the above description, the cash card is taken as an example of the recording medium, but the present invention is not limited to this. For example, the recording medium may be a credit card or a passbook. Even in such a case, it is possible to detect attachment of a skimming device that illegally reads customer information on a credit card or a passbook by detecting the metal member using the first detection member and the second detection member described above.

<3. Summary>
As described above, the first detection member (transmission coil 104 and reception coil 106) of the automatic transaction apparatus 10 is in the first region R1 through which the transaction card passes before being inserted into the card insertion slot 16a (for example, a magnetic field). The second detection member (transmission coil 104 and comparison coil 108) detects a situation in the second region R2 where the transaction card does not pass. And the control part 120 determines the presence or absence of the metal member (skimming apparatus 200) in 1st area | region R1 by comparing the detection result of a 1st detection member, and the detection result of a 2nd detection member.

  According to this configuration, the skimming device in the first region R1 in real time is obtained by comparing the detection result in the first region R1 by the first detection member and the detection result in the second region R2 by the second detection member. Whether 200 is attached can be detected. Moreover, since the 2nd detection member is provided in the area | region where a transaction card does not pass, even if it changes the shape of the skimming apparatus 200 according to the shape of the card insertion part 16, 1st area | region R1 by a 1st detection member As long as the skimming device 200 is attached, the detection result of the first region R1 by the first detection member is compared with the detection result of the second region R2 by the second detection member. And third parties cannot avoid detection. As a result, the skimming device 200 attached to the card insertion unit 16 can be detected more appropriately.

  Further, for example, by alerting the customer from the automatic transaction apparatus 10, it is possible to prevent the customer from inserting a transaction card into the automatic transaction apparatus 10 to which the skimming apparatus is attached by mistake.

  Further, since the oscillation circuit 112 is oscillated (a magnetic field is generated) when the customer does not perform a transaction, the magnetic stripe of the transaction card can be prevented from being destroyed by the magnetic field generated by the transmission coil 104.

  The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious that a person having ordinary knowledge in the technical field to which the present invention pertains can come up with various changes or modifications within the scope of the technical idea described in the claims. Of course, it is understood that these also belong to the technical scope of the present invention.
