Description

[Technical Field]

[0001] The present disclosure relates to payment terminals. [Background technology]

[0002] A payment terminal is a device that is installed, for example, at a store counter and is used to make payments. With the recent diversification of transactions, payment locations are expanding beyond store counters to various other locations. For example, payments for parcel deliveries are now made at the delivery destination. For this reason, portable payment terminals that can be carried around are becoming increasingly important.

[0003] Information that requires a high level of security is input into a payment terminal, and the information is recorded in electronic components installed inside. Therefore, payment terminals are required to be tamper-resistant to protect the internal electronic components. Patent Document 1 discloses a data storage device that can be used in payment terminals, and that has a connector that is installed between substrates and connected to wiring to ensure tamper resistance. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-33593 Summary of the Invention [Problem to be solved by the invention]

[0005] When the data storage device of Patent Document 1 is applied to a payment terminal, it is difficult to ensure the degree of freedom in the placement of connectors in order to improve security.

[0006] The present disclosure provides a payment terminal that can improve security and increase the degree of freedom in arranging a connector that connects a substrate to a component having a wiring pattern for ensuring tamper resistance. [Means for solving the problem]

[0007] One aspect of the present disclosure is a payment terminal comprising: a substrate on which security components requiring security are mounted; a tamper-resistant unit having a wiring pattern, arranged opposite the substrate and covering the security components mounted on the substrate; and three or more connectors that connect the substrate and the tamper-resistant unit and through which at least one signal line that is conductive to at least one of the wiring patterns passes, at least one of the three or more connectors having only one of the signal lines passing through. [Effects of the Invention]

[0008] According to the present disclosure, it is possible to improve security and increase the degree of freedom in arranging a connector that connects a substrate to a member having a wiring pattern for ensuring tamper resistance. [Brief explanation of the drawings]

[0009] [Figure 1] FIG. 1 is a front view of a payment terminal according to an embodiment of the present disclosure. [Figure 2] Exploded perspective view of the payment terminal from the front [Figure 3] Exploded perspective view of the payment terminal from the back side [Figure 4] 1 is a cross-sectional view of an LDS and a substrate in a payment terminal according to an embodiment. [Figure 5] FIG. 1 is a plan view of a substrate in a payment terminal according to an embodiment; [Figure 6] Schematic diagram of wiring pattern in LDS [Figure 7] Cross-sectional view of the LDS and the substrate in the payment terminal of the first comparative example [Figure 8] 1 is a plan view of a circuit board in a payment terminal according to a first comparative example; [Figure 9] Cross-sectional view of the LDS and the substrate in the payment terminal of the second comparative example

[0010] Hereinafter, embodiments will be described in detail with reference to the drawings as appropriate. However, more detailed description than necessary may be omitted. For example, detailed description of well-known matters or redundant description of substantially identical configurations may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. Note that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0011] (How the embodiments of the present disclosure were achieved) When the data storage device of Patent Document 1 is applied to a payment terminal, the payment terminal can include a substrate, a member having a wiring pattern and covering electronic components mounted on the substrate, and a connector connecting the substrate and the tamper-resistant unit. Patent Document 1 also provides only one type of wiring pattern for ensuring tamper resistance. On the other hand, if the payment terminal is provided with multiple types (also referred to as multiple rows) of wiring patterns (for example, two types (two rows)) for ensuring tamper resistance, security can be further improved. In this case, multiple rows of signal lines that are electrically connected to each of the multiple rows of wiring patterns are built into the connector that connects the substrate and the tamper-resistant unit.

[0012] Portable payment terminals need to be miniaturized, but miniaturization limits the area in which electronic components can be placed within the terminal. Therefore, when considering the placement of electronic components within a payment terminal, connectors with multiple rows of built-in signal lines have limited freedom in placement, making design difficult.

[0013] In the following embodiment, a payment terminal will be described that can improve security and increase the degree of freedom in arranging a connector that connects a substrate to a component having a wiring pattern for ensuring tamper resistance.

[0014] (Embodiment)

[0015] Fig. 1 is a top view of a payment terminal 1 according to an embodiment of the present disclosure. Fig. 2 is an exploded perspective view of the payment terminal 1 as viewed from the front side. Fig. 3 is an exploded perspective view of the payment terminal 1 as viewed from the back side. In each figure, the X-axis direction is a direction along the touch panel surface (e.g., the short side direction), the Y-axis direction is a direction along the touch panel surface that is perpendicular to the X-direction (e.g., the long side direction), and the Z-axis direction is a direction perpendicular to the touch panel surface (e.g., the thickness direction or height direction).

[0016] The payment terminal 1 is a multi-type terminal that allows a purchaser of a product or the like to select from multiple payment methods. The multiple payment methods include, for example, credit card payment, electronic money payment, code (e.g., QR Code (registered trademark)) payment, and cash payment. Credit card payment includes, for example, magnetic card payment, contact IC card payment, and contactless IC card payment. There may be multiple types of electronic money. Electronic money payment and contactless IC card payment are performed using contactless communication (e.g., near field communication: NFC), and are therefore collectively referred to here as contactless payment.

[0017] The payment terminal 1 includes a housing 10, a substrate 20, an LDS (Laser Direct Structuring) 30 constituting a tamper-resistant section, a touch panel 41, a display 42, and a connector with a built-in signal line (also referred to as a "signal line built-in connector"). As shown in Figures 2 and 3, the housing 10 is configured by combining a first exterior case 11 on the front side and a second exterior case 12 on the back side in the Z-axis direction. The first exterior case 11 and the second exterior case 12 are formed from, for example, resin.

[0018] The board 20 is disposed in the internal space of the housing 10, and various electronic components are mounted on it. The electronic components include security components that require security. Information that requires a high level of security, such as personal information, is input into the payment terminal 1, and since this information is recorded at least temporarily in the security components, the security components must be highly tamper-resistant.

[0019] The LDS30 constituting the tamper-resistant section is a resin housing with a circuit formed using three-dimensional wiring technology. The LDS30 is disposed opposite the substrate 20 (for example, on the back side of the substrate 20) and covers the security component mounted on the substrate 20. The LDS30 has a wiring pattern to which signals are supplied from a predetermined component (for example, a processor (e.g., a CPU)) provided in the payment terminal 1. For example, if a malicious third party destroys the LDS30 in order to obtain information, the wiring pattern of the LDS30 is also destroyed (disconnected), making it impossible to access the information recorded in the security component, thereby ensuring tamper resistance. The LDS30 also has multiple types (multiple rows) of wiring patterns.

[0020] The LDS 30 is, for example, a flat plate-shaped member, and includes a planar portion and a frame portion provided around the planar portion. The planar portion has an area where a wiring pattern is arranged. The planar portion may or may not have an area without a wiring pattern. Furthermore, a wiring pattern may also be arranged on the frame portion.

[0021] The touch panel 41 receives and detects input of various data and information related to payment processing (such as selection of payment method, personal identification number, PIN (Personal Identification Number), or electronic signature) by a store clerk or customer.

[0022] The display 42 is, for example, a liquid crystal display, an organic EL display, or other display. The display 42 displays, for example, various data and information related to the payment process.

[0023] The touch panel 41 and the display 42 are attached to the first exterior case 11 and electrically connected to the substrate 20 .

[0024] The signal line built-in connector connects the substrate 20 and the LDS 30, and also electrically connects them. A plurality of signal line built-in connectors are provided. The signal line built-in connector has at least one row of signal lines that are electrically connected to each of the multiple rows (for example, two rows) of wiring patterns of the LDS 30 built-in. The signal line built-in connectors are, for example, a first connector 51, a second connector 52, and a third connector 53, which will be described later.

[0025] In addition to the above, payment terminal 1 also includes, for example, an NFC antenna, a magnetic card reader, a contact IC card reader, a camera, and a processor. Payment terminal 1 may also include other components. Payment terminal 1 is a type of electronic device that performs payment processing.

[0026] The NFC antenna is a communication antenna for contactless communication, which detects a communication medium such as a contactless IC card or a high-frequency identification device tag, and communicates wirelessly with the detected communication medium. The NFC antenna communicates with a contactless IC card (e.g., a contactless credit card or an electronic money card), reads information stored in the contactless IC card, and writes information to the contactless IC card. The NFC antenna is disposed, for example, near the touch panel 41.

[0027] The magnetic card reader reads information stored on a magnetic card swiped through a magnetic card slot. The contact IC card reader reads information stored on a contact IC card inserted into a contact IC card slot and writes information to the contact IC card. The camera captures, for example, a code (e.g., a barcode or a two-dimensional code (e.g., a QR code (registered trademark)) displayed on the terminal.

[0028] The processor controls each component of the payment terminal 1, realizes various functions (for example, a payment function), and performs various processes. For example, the processor recognizes a code captured by a camera and reads the code information. The processor performs payment-related processes based on the information read from various cards and codes. The processor may also control contactless communication using an NFC antenna. Note that multiple processors may be provided, with different processors used for each function, or multiple functions may be realized by a single processor.

[0029] When a conventional tamper-resistant device is applied to a payment terminal, for example, to enhance security, multiple rows of wiring patterns to ensure tamper resistance are wired on a member covering a board on which electronic components are mounted (in this embodiment, the main body of the LDS30). A connector with built-in signal lines that is electrically connected to the wiring patterns is also provided between this member and the board. Multiple rows of signal lines that are electrically connected to each of the multiple rows of wiring patterns are built into this connector with built-in signal lines.

[0030] Portable payment terminals need to be compact, but miniaturization limits the space available for placing electronic components. Therefore, when considering the placement of electronic components inside a payment terminal, connectors with built-in signal lines, which have multiple rows of built-in signal lines, offer limited freedom in placement, making their design difficult.

[0031] Therefore, the inventors realized that by providing a single line (a single row of signal lines) in at least one connector with built-in signal lines, the placement area of ​​the connector with built-in signal lines can be reduced, thereby improving the freedom of placement of the connector with built-in signal lines.

[0032] Fig. 4 is a cross-sectional view of LDS 30 and substrate 20 in payment terminal 1 according to the embodiment. Fig. 5 is a plan view of substrate 20 in payment terminal 1 according to the embodiment, with the position of LDS 30 indicated by a dashed line.

[0033] A plurality of security components and a plurality of connectors with built-in signal lines are mounted on the substrate 20. The plurality of security components may include, for example, security components 61, 62, 63, 64, 65, 66, 67, 68, and 69. The plurality of connectors with built-in signal lines may include, for example, three connectors with built-in signal lines: a first connector 51, a second connector 52, and a third connector 53. The first connector 51, the second connector 52, and the third connector 53 each connect the substrate 20 and the LDS 30, ensuring electrical connection between the substrate 20 and the LDS 30.

[0034] At least one signal line (one type, one row) that is electrically connected to at least one wiring pattern (one type, one row) of the LDS 30 passes through each of the first connector 51, the second connector 52, and the third connector 53. In this embodiment, an example is mainly shown in which there are two rows of wiring patterns and two rows of signal lines, but there may be three or more rows of each. In FIG. 4, two rows of signal lines, the first signal line 71 and the second signal line 72, are wired between the substrate 20 and the LDS 30 and are also connected to the security component 61.

[0035] 4, the first signal line 71 is wired by electrically connecting the security component 61, the substrate 20, the first connector 51, the LDS30 (wiring pattern), the second connector 52, the substrate 20, and the security component 61 in this order. The second signal line 72 is wired by electrically connecting the security component 61, the substrate 20, the first connector 51, the LDS30 (wiring pattern), the third connector 53, the substrate 20, and the security component 61 in this order.

[0036] The first signal line 71 and the second signal line 72 may be electrically connected by independent signal lines in each of the above components, or may be signal lines that are at least partially physically connected. Within the LDS30, the first signal line 71 becomes a first wiring pattern row, and the first signal line 71 of the connector with a built-in signal line and the wiring pattern of the LDS30 are electrically connected. In the LDS30, the second signal line 72 becomes a first wiring pattern row, and the second signal line 72 of the connector with a built-in signal line and the wiring pattern of the LDS30 are electrically connected.

[0037] 4, of the first connector 51, the second connector 52, and the third connector 53, two of the first signal line 71 and the second signal line 72 pass through the second connector 52, only the first signal line 71 passes through the second connector 52, and only the second signal line 72 passes through the third connector 53. With this configuration, the payment terminal 1 can reduce the arrangement area of ​​the second connector 52 and the third connector 53, and can improve the degree of freedom in the arrangement of the connectors with built-in signal lines (particularly the second connector 52 and the third connector 53).

[0038] As shown in FIG. 4, the predetermined component that supplies a signal to the wiring pattern of the LDS 30 may be, for example, the security component 61, other security components 62 to 69, or a component other than a security component.

[0039] As shown in Fig. 5, at least one of the first connector 51, the second connector 52, and the third connector 53 may be disposed near at least one of the security components 61 to 69. In Fig. 5, security components 65, 66, and 67, for example, are disposed near the first connector 51. Security components 63 and 64, for example, are disposed near the second connector 52. Security components 68 and 69, for example, are disposed near the third connector 53.

[0040] As a result, for example, if a third party attempts to access at least one of the security components 61-69 from outside the LDS 30, there is a high possibility that the connector with built-in signal line disposed near at least one of the security components 61-69 will be disconnected or damaged. For example, in the case of an attack on security components 65, 66, and 67, the payment terminal 1 can easily detect the attack by disconnecting or shorting the first signal line 71 or the second signal line 72 in the first connector 51. For example, in the case of an attack on security components 63 and 64, the payment terminal 1 can easily detect the attack by disconnecting or shorting the first signal line 71 or the second signal line 72 in the second connector 52. For example, in the case of an attack on security components 68 and 69, the payment terminal 1 can easily detect the attack by disconnecting or shorting the first signal line 71 or the second signal line 72 in the third connector 53.

[0041] In this way, payment terminal 1 can easily detect attacks on at least one of security components 61-69 inside LDS 30. Furthermore, by arranging the signal line connector near the security component, it becomes difficult to open LDS 30 of payment terminal 1. Furthermore, by making the signal line connector smaller (slimmerized), payment terminal 1 can improve the flexibility of arranging the signal line connector, making it easier to arrange the signal line connector near the security component, which can also be said to further improve security.

[0042] Next, a specific example of a security component will be described.

[0043] The highly confidential information stored in the security component includes, for example, important information related to payments, such as identification information of cards used for payments (e.g., credit cards, electronic money cards), personal identification numbers, PINs (Personal Identification Numbers), passwords, and electronic signatures.

[0044] The security component may include, but is not limited to, the following components: For example, the security component may include an ICC (IC Card) connector (an example of a first connector) electrically connected to an IC card inserted into the contact IC card slot of the payment terminal 1; a TS (Touch Screen) connector (an example of a second connector) electrically connected to the touch panel 41; a display connector (an example of a third connector) such as an LCD (Liquid Crystal Display) connector electrically connected to the display 42; a MSR (Magnetic Stripe Reader) connector (an example of a fourth connector) electrically connected to a magnetic reader (magnetic card reader) of the payment terminal 1; a processor (an example of a first processor) that performs processing related to payment; a processor (an example of a second processor) that performs processing related to contactless communication; a memory that records information; and a signal line-integrated connector, which is also a necessary component for achieving tamper resistance and therefore requires high security, are included as a security component.

[0045] The processor that performs the payment processing and the processor that performs the contactless communication processing may be one processor or different processors. Furthermore, the memory may be provided independently of the processor or may be built into the processor.

[0046] It should be noted that which of the above security components is mounted on the board 20 as any of the security components 61 to 69 in FIG. 4 is arbitrary.

[0047] As a result, the payment terminal 1 can treat components that may at least temporarily store important information related to payment as security components, and can protect such security components efficiently with the LDS 30.

[0048] FIG. 6 is a schematic diagram of the wiring pattern in the LDS30.

[0049] A wiring pattern 311 is provided on at least the planar portion of the LDS 30. The wiring pattern 311 in FIG. 6 is at least a part of the wiring pattern provided on the planar portion. The wiring pattern 311 includes a first wiring pattern row 312 and a second wiring pattern row 313 that are independent of each other, with a gap 314 provided between the two rows. By providing two rows of wiring patterns in this manner, security is enhanced. The width of the first wiring pattern row 312, the width of the second wiring pattern row 313, and the size of the gap 314 are all, for example, 0.3 mm. Note that the width of the wiring pattern row and the size of the gap may be different values.

[0050] 4 is electrically connected to, for example, a first wiring pattern row 312 of the wiring pattern of the LDS 30. The second signal line 72 in FIG. 4 is electrically connected to, for example, a second wiring pattern row 313 of the wiring pattern of the LDS 30.

[0051] When the LDS30 has two rows of wiring patterns (for example, a first wiring pattern row 312 and a second wiring pattern row 313), each wiring pattern can transmit a different signal. In this case, the LDS30 can detect tampering when one of the wiring patterns is broken, and can also detect electrical abnormalities (for example, short circuits) caused by electrical contact between multiple types of wiring patterns, thereby improving security. For example, if a third party attempts to attack the LDS30 by drilling a hole in it with a metal drill, the LDS30 can detect tampering by detecting electrical contact between nearby wiring patterns (signal lines).

[0052] Furthermore, at least the planar portion of LDS30 may be provided with a plurality of regions in which the pattern width of wiring pattern 311 differs from one another, for example, a first region and a second region may be provided. At least the planar portion of LDS30 may also have a region without a wiring pattern. For example, the first region may be a region that faces a security component mounted on substrate 20 in the Z-axis direction. For example, the second region may be a region that does not face a security component in the Z-axis direction. The second region may be a region that faces only substrate 20, or a region that may face electronic components other than security components that do not require security.

[0053] Next, the present embodiment will be compared with a comparative example. In the comparative example, the same configuration as in this embodiment will be described using the same name and with an "X" added to the end of the reference numeral.

[0054] Fig. 7 is a cross-sectional view of LDS30X and substrate 20X in payment terminal 1X of the first comparative example. Fig. 8 is a plan view of substrate 20X in payment terminal 1X of the first comparative example. In the first prior art, two signal line built-in connectors, a first connector 51X and a second connector 52X, are mounted on substrate 20X.

[0055] 7, the first signal line 71X is electrically connected and wired in the order of security component 61X, substrate 20X, first connector 51X, LDS30X (wiring pattern), second connector 52X, substrate 20X, and security component 61X. Similar to the first signal line 71X, the second signal line 72X is wired in the order of security component 61X, substrate 20X, first connector 51X, LDS30X (wiring pattern), second connector 52X, substrate 20X, and security component 61X.

[0056] The first signal line 71X and the second signal line 72X may be electrically connected by independent signal lines in each of the components, or may be signal lines that are at least partially physically connected. Within the LDS30X, the first signal line 71X forms a first wiring pattern row, and the first signal line 71X of the connector with a built-in signal line and the wiring pattern of the LDS30X are electrically connected. Within the LDS30X, the second signal line 72X forms a first wiring pattern row, and the second signal line 72X of the connector with a built-in signal line and the wiring pattern of the LDS30X are electrically connected.

[0057] In the first comparative example, multiple (two) signal lines (first signal line 71X and second signal line 72X) are built into both the first connector 51X and the second connector 52X, making it difficult to reduce the area required for arranging the signal line-integrated connectors. Also, the number of signal line-integrated connectors connecting the board 20X and the LDS 30X is two, which provides a lower security level than the configuration of this embodiment, which has three or more signal line-integrated connectors.

[0058] 8, for example, security components 65X, 66X, and 67X are arranged near first connector 51X. For example, security components 63X and 64X are arranged near second connector 52X. However, no signal line connectors are arranged near security components 68 and 69. In this case, for example, if an attack is attempted on security components 68 and 69, for example, by using the principle of leverage to open LDS 30 from near security components 68 and 69, no disconnection or short circuit of the signal line connectors will occur, making it difficult to detect the attack.

[0059] 9 is a cross-sectional view of an LDS 30X and a substrate 20X in a payment terminal of Comparative Example 2. In Comparative Example 2, a first connector 51X, a second connector 52, and a third connector 53 are mounted on a substrate 20.

[0060] 9, the first signal line 71X is wired by electrically connecting the security component 61X, the board 20X, the first connector 51X, the LDS30X (wiring pattern), the second connector 52X, the board 20X, and the security component 61X in this order. The second signal line 72X is wired by electrically connecting the security component 61X, the board 20X, the first connector 51X, the LDS30X (wiring pattern), the third connector 53X, the board 20X, the third connector 53X, the LDS30X (wiring pattern), the second connector 52X, the board 20X, and the security component 61X in this order.

[0061] The first signal line 71X and the second signal line 72X may be electrically connected by independent signal lines in each of the components, or may be signal lines that are at least partially physically connected. Within the LDS30X, the first signal line 71X forms a first wiring pattern row, and the first signal line 71X of the connector with a built-in signal line and the wiring pattern of the LDS30X are electrically connected. Within the LDS30X, the second signal line 72X forms a first wiring pattern row, and the second signal line 72X of the connector with a built-in signal line and the wiring pattern of the LDS30X are electrically connected.

[0062] In the second comparative example, each of the first connector 51X, the second connector 52X, and the third connector 53X has multiple (two) signal lines (first signal line 71X and second signal line 72X) built in, making it difficult to reduce the layout area of ​​the connectors with built-in signal lines. Furthermore, each of the three connectors with built-in signal lines has multiple signal lines built in. Therefore, the total layout area of ​​the connectors with built-in signal lines is large, limiting the degree of freedom in arranging the connectors with built-in signal lines.

[0063] In contrast, payment terminal 1 of this embodiment differs from the first and second comparative examples in that only one signal line is built into and passes through at least one connector with built-in signal line, as shown in Fig. 4. Therefore, payment terminal 1 can miniaturize the connector with built-in signal line that has only one built-in signal line, which means that the layout area of ​​the connector with built-in signal line can be reduced, and the degree of freedom in layout of the connector with built-in signal line that connects LDS 30 and board 20 can be improved.

[0064] Furthermore, in order to wire two rows of signal lines between the substrate 20 and the LDS 30 and to incorporate only one signal line into at least one connector with a built-in signal line, at least three connectors with a built-in signal line are required. Therefore, the payment terminal 1 has at least three connectors with a built-in signal line.

[0065] As shown in FIG. 6 , each of the multiple wiring pattern rows (e.g., the first wiring pattern row 312 and the second wiring pattern row 313, which are independent of each other in the wiring pattern 311) is wired in the LDS 30 in a single stroke, while avoiding contact with other wiring pattern rows. Therefore, the greater the number of signal line connectors, the more difficult it is to determine the layout of the wiring patterns between the two signal line connectors. Therefore, by providing the payment terminal 1 with three signal line connectors, the degree of freedom in the layout of the signal line connectors is improved compared to the prior art and comparative examples, while preventing the difficulty in determining the wiring layout. Meanwhile, the payment terminal 1 may be provided with four or more signal line connectors connecting the substrate 20 and the LDS 30, and the number of signal line connectors can be determined taking into account the balance with the degree of freedom in the layout of the signal line connectors. For example, increasing the number of signal line connectors in the payment terminal 1 makes it easier to arrange the signal line connectors near multiple security components, thereby improving security.

[0066] Furthermore, when only one signal line passes through each of the two connectors, second connector 52 and third connector 53, as shown in FIG. 4, the payment terminal 1 can further improve the freedom of arrangement of the connector with built-in signal line.

[0067] As described above, the payment terminal 1 of this embodiment is provided with three or more signal line connectors, and a single signal line passes through at least one of the signal line connectors, compared to a case where only two signal line connectors are provided. Therefore, the payment terminal 1 can have at least one signal line connector that is smaller (slimmerized), reducing the area required for arranging the signal line connectors and improving the flexibility of their placement. Even in this case, high security can be ensured for the security components surrounded by the tamper-resistant section. Particularly when the payment terminal 1 is made smaller, for example, when it is made into a portable payment terminal, the area available for mounting each component is small. Even in this case, the miniaturized signal line connector can be easily arranged near the security component as a contact point connecting the substrate 20 and the LDS30. Therefore, security against opening the LDS30 can be further improved. For example, even when the wiring pattern 311 is arranged over a wide area on the planar surface of the LDS30, the miniaturization of the signal line connector allows for flexible determination of the placement of the signal line connector.

[0068] Although the LDS 30 has been described as having two rows (two types) of wiring pattern rows, the present invention is not limited to this, and the LDS 30 may have three or more rows (three types) of wiring pattern rows.

[0069] <Outline of this embodiment> As a result, the present disclosure describes at least the following: Note that, in parentheses, examples of components corresponding to those in the above-described embodiments are given, but the present disclosure is not limited to these.

[0070] (Item 1) a substrate (substrate 20) on which security components (such as security component 61) requiring security are mounted; a tamper-resistant section (LDS30) disposed opposite the substrate, covering the security component mounted on the substrate, and having a wiring pattern (wiring pattern 311); three or more connectors (a connector with a built-in signal line, a first connector 51, a second connector 52, and a third connector 53) that connect the substrate and the tamper-resistant unit and through which at least one signal line (a first signal line 71, a second signal line 72) that is electrically connected to at least one of the wiring patterns passes; Equipped with At least one of the three or more connectors has only one signal line passing through it; Payment terminal.

[0071] This allows the payment terminal to have three or more connectors, and a single wire passes through at least one connector, compared to when only two connectors are provided. This allows the payment terminal to reduce the area required for the placement of at least one connector, improving the flexibility of connector placement. Even in this case, the payment terminal can ensure high security for the security component surrounded by the tamper-resistant unit.

[0072] (Item 2) At least one of the connectors is located near the security component. Item 1. A payment terminal as described in item 1.

[0073] For example, if a third party attempts to access the security component from outside the tamper-resistant unit, there is a high possibility that the connector located near the security component will be cut or damaged. Therefore, the payment terminal can easily detect attacks on the security component inside the tamper-resistant unit.

[0074] (Item 3) The connector is provided in three pieces. Item 1 or 2. A payment terminal.

[0075] For example, each of the multiple wiring pattern rows is wired in a single stroke in the tamper-resistant section while avoiding contact with other wiring pattern rows. Therefore, the greater the number of connectors, the more difficult it becomes to determine the layout of the wiring patterns between the multiple connectors. Therefore, by using three connectors, the payment terminal can improve the flexibility of connector layout compared to conventional systems while reducing the difficulty of determining the wiring layout.

[0076] (Item 4) Two of the three connectors have only one signal line passing through them. A payment terminal as described in item 3.

[0077] This allows the payment terminal to have two smaller (slimmer) connectors, allowing for greater freedom in connector placement. (Item 5) The security component is a first connector electrically connected to an IC card inserted into the payment terminal; A second connector electrically connected to the touch panel (touch panel 41) of the payment terminal; a third connector electrically connected to a display (display 42) of the payment terminal; a fourth connector electrically connected to the magnetic reader of the payment terminal; and a first processor for performing processing related to payment; a second processor that performs processing related to contactless communication; A memory for recording information; including at least one of 5. A payment terminal according to any one of items 1 to 4.

[0078] This allows components that may at least temporarily hold important payment-related information (e.g., card identification information, PIN, password) to be treated as security components, and such security components can be efficiently protected by tamper-resistant sections and connectors that connect the board and tamper-resistant sections.

[0079] Although various embodiments have been described above with reference to the drawings, it goes without saying that the present disclosure is not limited to such examples. It is clear that a person skilled in the art can conceive of various modifications or alterations within the scope of the claims, and it is understood that these also naturally fall within the technical scope of the present disclosure. Furthermore, the components of the above-described embodiments may be combined in any manner without departing from the spirit of the invention. [Industrial Applicability]

[0080] The present disclosure is useful for payment terminals and the like that can improve security and increase the degree of freedom in arranging connectors that connect a substrate to a component having a wiring pattern for ensuring tamper resistance. [Explanation of symbols]
