Description

[Technical Field]

[0001] The present disclosure relates to a card reading device, a card reading method, and a program for reading information from a My Number card. [Background technology]

[0002] Conventionally, there is known a card processing device that can perform a predetermined process on a card without the card being inserted into the processing device in a specific orientation (see Patent Document 1). This card processing device includes: a transport means for transporting a card having a recordable surface on which card processing information can be recorded and on which orientation discrimination information for discriminating the front / back and front / back / left / right orientations is pre-written; a discrimination means for reading the orientation discrimination information from the card transported by the transport means and discriminating the front / back and front / back / left / right orientations of the card; a correction means for correcting the front / back and front / back / left / right orientations of the transported card based on the discrimination result obtained by the discrimination means; and a recording means for recording the card processing information on the recordable surface of the card whose front / back and front / back / left / right orientations have been corrected by the correction means.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-090204 Summary of the Invention [Problem to be solved by the invention]

[0004] The card processing device of Patent Document 1 has a card orientation correction unit as a correction means, which is provided with a rotation correction unit that rotates the front and rear ends of the prepaid card by 180 degrees and a switchback unit 17 that flips the front and back sides of the prepaid card. In other words, since the card is physically flipped, it takes time for the card to assume a position where it can be read. Furthermore, in recent years, services using My Number cards (personal identification number cards) have been increasing, making it necessary to accurately read My Number cards.

[0005] The present disclosure has been made in consideration of the above circumstances, and provides a card reading device, a card reading method, and a program that can quickly read information stored on a My Number card without having to worry about the front or back of the card. [Means for solving the problem]

[0006] One aspect of the present disclosure is a card reading device that reads information from a My Number card, comprising: an IC reading unit that reads information from the IC chip of the My Number card; a first imaging unit that images the My Number card; and a control unit that controls the IC reading unit, wherein the control unit determines whether the face of the My Number card imaged by the first imaging unit is the front or back based on the image captured by the first imaging unit, and if the face of the My Number card is the back, obtains an image of the face of the My Number card from the IC chip via the IC reading unit, and obtains the four pieces of information based on the image of the face of the card.

[0007] One aspect of the present disclosure is a card reading method for reading information from a My Number card, the card reading method comprising the steps of: capturing an image of the My Number card; determining, based on the captured image, whether the captured face of the My Number card is the front or back face; and, if the face of the My Number card is the back face, acquiring an image of the My Number card face from the IC chip via the IC reading unit, and acquiring the four pieces of information based on the image of the card face.

[0008] One aspect of the present disclosure is a program for causing a computer to execute the card reading method described above. [Effects of the Invention]

[0009] According to the present disclosure, the information stored on the My Number card can be quickly read without having to worry about the front or back of the card face. [Brief explanation of the drawings]

[0011] 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 descriptions of well-known matters or descriptions 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.

[0012] <Configuration of card reader> Fig. 1A is a diagram showing an example of the configuration of a card reading device 100 according to the first embodiment. Fig. 1B is a see-through view of the card reading device 100 from the side.

[0013] The card reading device 100 reads personal information stored in the IC chip of the card 10 from the card 10. The card 10 includes at least a My Number card 10M and may include other cards. The other cards may include, for example, a passport, a residence card, or a driver's license. The card 10 may be in a form other than a card and may broadly include any identification document capable of verifying the identity of the user. The personal information here is information capable of identifying the user of the card 10, and includes, for example, name, address, date of birth, gender, facial image, or other information. The card reading device 100 also operates as an authentication device.

[0014] The card reading device 100 has a mounting base 101. A card (e.g., an Individual Number card 10M) is placed on the mounting base 101 at a predetermined position. The card reading device 100 has an opening 102 on the front surface S1 of the card reading device 100, and the opening 102 communicates with the mounting base 101.

[0015] The user UR placing the card 10 inserts the card 10 into the opening 102 from the front side of the opening 102 and can place the card 10 with the front surface FS of the card 10 facing up (toward the card imaging unit 160), or can place the card 10 with the back surface BS facing up. The user UR can place the card 10 with the bottom side of the card 10 facing the front side of the placing table 101 (the side closer to the user UR), or can place the card 10 with the bottom side of the card 10 facing the back side of the placing table 101 (the side farther from the user UR). The user UR can place the card 10 with the bottom side of the card 10 facing one side wall of the placing table 101, or can place the card 10 with the bottom side of the card 10 facing the other side wall of the placing table 101. The top and bottom of the card 10 can be determined from the direction of the text written on the face of the card 10 or the direction of the facial image.

[0016] The card reading device 100 has, on its front surface S1, a touch panel that also serves as an operation panel 130 and a display 140, and a face imaging unit 150. The front surface S1 of the card reading device 100 is inclined with respect to the direction of gravity, for example, so that it is easily visible to a user UR positioned opposite the card reading device 100. The back surface S2 of the card reading device 100 (the side opposite the user UR) is aligned with the direction of gravity, for example. The operation panel 130 accepts, for example, input of a personal identification number or the like by the user UR. The display 140 displays, for example, information instructing how to operate the card reading device 100 with the card 10, the results of reading the card 10, or warning information.

[0017] As shown in FIG. 1B, the housing of the card reading device 100 includes a card imaging unit 160. The card imaging unit 160 images the card 10 placed on the mounting base 101 from above. Therefore, the card imaging unit 160 images the top surface of the card 10 placed on the mounting base 101. The top surface of the card 10 here can be the front surface FS of the card 10 or the back surface BS of the card 10. For example, the entire card 10 is included in the imaging range CA of the card imaging unit 160.

[0018] 2A is a block diagram showing an example configuration of card reading device 100. Card reading device 100 includes a processor 110, memory 120, operation panel 130, display 140, face imaging unit 150, card imaging unit 160, and IC (Integrated Circuit) reader 170. Card reading device 100 also includes a communication unit for wired or wireless communication, and may be able to communicate with other devices or connect to the cloud.

[0019] The processor 110 executes programs stored in the memory 120 to realize various functions. The processor may include an MPU (Micro Processing Unit), a CPU (Central Processing Unit), a DSP (Digital Signal Processor), etc. The processor 110 operates as a control unit that controls each component of the card reading device 100. The processor 110 performs, for example, processing related to the operation of reading information from the card 10. Alternatively, the processor 110 controls imaging by the face imaging unit 150 or the card imaging unit 160, performs OCR (Optical Character Recognition), or performs processing for personal authentication (including face authentication processing by matching facial feature amounts of a captured face image with facial feature amounts of a face image stored in an IC chip), etc.

[0020] The memory 120 includes a primary storage device (e.g., a random access memory (RAM) or a read only memory (ROM)). The memory 120 may include a secondary storage device (e.g., a hard disk drive (HDD) or a solid state drive (SSD)) or a tertiary storage device (e.g., an optical disk or an SD card). The memory 120 may include other storage devices. The memory 120 stores various data, information, programs, etc. The memory 120 holds images captured by the face imaging unit 150 or the card imaging unit 160, information obtained by reading by the IC reader 170, information obtained by reading by the OCR function, authentication results of personal authentication, etc.

[0021] Operation panel 130 accepts input of various data or information, etc. Instead of operation panel 130, for example, various operation devices (a mouse, a keyboard, a touchpad, a microphone, or other input devices that accept operations) may be included. Operation panel 130 is included in, for example, a touch panel.

[0022] The display 140 may include a liquid crystal display device, an organic EL device, or other display device. The display 140 displays various data, information, etc. The display 140 is included in, for example, a touch panel.

[0023] The face imaging unit 150 is installed on the front S1 of the card reading device 100, and captures an image of a subject (e.g., the face of the user UR) positioned opposite the face imaging unit 150. The card imaging unit 160 is installed, for example, inside the housing of the card reading device 100, and captures an image in the direction of the placing table 101. Therefore, when a card 10 is placed on the placing table 101, the card imaging unit 160 captures an image of the face (top surface) of the placed card 10.

[0024] The IC reader 170 reads at least a portion of the information stored in the IC chip 11 of the card 10 (embedded in the card 10). The IC chip 11 can restrict access to information using access information. The information that can be read from the IC chip 11 may vary depending on the access information.

[0025] The IC reader 170 has a contactless communication antenna 171 (for example, an NFC (Near Field Communication) antenna). The IC reader 170 reads information stored in the IC chip 11 in a contactless manner using the contactless communication antenna 171. Note that the IC reader 170 may also read information stored in the IC chip 11 in a contactless manner.

[0026] <Configuration of My Number Card> Next, the configuration of the My Number Card 10M will be described.

[0027] 2B is a block diagram showing an example of the configuration of the My Number card 10M. The My Number card 10M has an IC chip 11 and a contactless communication antenna 12 (for example, an NFC antenna).

[0028] The IC chip 11 stores information about a person (user UR of the My Number card 10M) identified by the My Number (personal number) on the My Number card 10M. Specifically, the IC chip 11 stores, for example, text information on four pieces of information about the person (name, address, date of birth, and gender), a facial image of the person (face image), and an image (card face image) that includes the card face on the front FS and the card face on the back BS. The card face image may include both the card face on the front FS and the card face on the back BS in a single card face image, or the card face image on the front FS and the card face image on the back BS (back card face image) may be separate.

[0029] The contactless communication antenna 12 is electrically connected to the IC chip 11. The contactless communication antenna 12 is capable of communicating with other contactless communication antennas (for example, the contactless communication antenna 171 of the IC reader 170 of the card reading device 100). For example, the contactless communication antenna 12 receives access information for accessing the My Number card 10M obtained by the operation panel 130 or the processor 110 from the card reading device 100, and sends this access information to the IC chip 11. Based on the access information, the contactless communication antenna 12 acquires at least a portion of the information held in the IC chip 11 from the IC chip 11, and transmits it to another device (for example, the contactless communication antenna 171 of the IC reader 170). The access information includes, for example, a verification number A, a verification number B, and a PIN code, which will be described later.

[0030] FIG. 3A is a diagram showing an example of the front surface FS of the My Number card 10M. FIG. 3B is a diagram showing an example of the back surface BS of the My Number card 10M. The name, address, date of birth, gender, and facial photo (facial image) of the person identified by the My Number on the My Number card 10M are printed on the front surface FS of the My Number card 10M. The name, date of birth, My Number, and two-dimensional code (e.g., QR Code (registered trademark)) of the person identified by the My Number on the My Number card 10M are printed on the back surface BS of the My Number card 10M. The two-dimensional code contains information indicating the My Number.

[0031] Fig. 3C is a diagram showing the configuration of the application AP included in the IC chip 11. Fig. 3D is a diagram showing an overview of the application AP of the My Number card 10M and access control.

[0032] The application APs stored in the IC chip 11 include a card application (card AP), a card information input assistance application (card information input assistance AP), a resident registration application (resident registration AP), a JPKI-AP (public personal authentication application (public personal authentication AP)), and a platform. The application APs may also include a municipal ordinance utilization application (municipal ordinance utilization AP).

[0033] When the IC chip 11 receives the verification number A as access information from the card reading device 100, the card reading device 100 accesses the face AP to acquire face information (face image) and a facial image on the front FS and back BS of the My Number card 10M. The card reading device 100 accesses the face AP via the non-contact communication antenna 12 of the My Number card 10M to acquire face information (face image) and a facial image on the front FS and back BS of the My Number card 10M. At this time, the card reading device 100 acquires the access information by, for example, performing character recognition on an image of the back BS of the My Number card 10M. The verification number A is information on the 12-digit My Number. The face image includes information visible on each of the front FS and back BS of the My Number card 10M as image information, that is, information that can be recognized externally. Specifically, the card face image includes the four information and a facial photograph image (face image) as the front information (card face image on the front FS), and includes an image of the Individual Number as the back information (card face image on the back BS). The facial image is the same as the facial photograph image (face image) included in the front information (card face image on the front FS). Furthermore, when IC chip 11 obtains verification number A as access information, card reading device 100 accesses card face information input assistance AP via non-contact communication antenna 12, thereby enabling acquisition of the Individual Number and its electronic signature data as text data.

[0034] When the IC chip 11 receives the verification number B as access information from the card reading device 100, the card reading device 100 accesses the card face AP to acquire a card face image and a facial image of the front FS. The card reading device 100 acquires the access information by accessing the card face AP via the non-contact communication antenna 12 of the Individual Number card 10M. At this time, the card reading device 100 acquires the access information by, for example, performing character recognition on an image of the front FS of the Individual Number card 10M. The facial image is the same as the facial image contained in the card face image of the front FS. The verification number B is 14-digit information including a six-digit date of birth, a four-digit year portion of the expiration date, and a four-digit security code. Furthermore, when the IC chip 11 receives the verification number B as access information for the card face information input assistance AP, the card reading device 100 accesses the card face information input assistance AP via the non-contact communication antenna 12 to acquire the four pieces of information as text data and their electronic signature data.

[0035] When the IC chip 11 obtains a personal identification number (PIN code) as access information, the card reader 100 can obtain the My Number and the four information as text data and their electronic signature data by accessing the card information input assistance AP via the non-contact communication antenna 12. The personal identification number referred to here may be, for example, a PIN for assisting the input of card information on the My Number card.

[0036] The provision of information corresponding to each piece of access information from the My Number card 10M by the IC chip 11 may be limited to cases where personal authentication is successful. In other words, the IC chip 11 may acquire the access information and allow the card reading device 100 to acquire the information corresponding to the access information only when personal authentication success information is acquired.

[0037] <Configuration of card reader> Next, an example of the operation of the card reader 100 will be described. 4A to 4C are flowcharts showing an example of the operation of the card reading device 100. FIG.

[0038] The user UR places the card 10 held by the user UR on the placement table 101 of the card reading device 100. At this time, the card reading device 100 may detect that the card has been placed on the placement table 101 by, for example, constantly photographing the card face, constantly outputting radio waves from the non-contact communication antenna 171, and detecting the card by communicating with the card when it is placed, etc. The card imaging unit 160 captures an image of the top surface of the card 10 (the surface facing the card imaging unit 160) to obtain a captured card image. The processor 110 determines whether the card 10 is a My Number card 10M based on the captured card image (S11). For example, the processor 110 may determine that the card 10 is a My Number card 10M if the captured card image corresponds to the card face image of the front surface FS or the back surface BS (for example, if they have the same layout). Furthermore, the processor 110 may perform OCR processing on the captured image of the card to recognize the card face, and if the information on the recognized card face contains information indicating the My Number card 10M, determine that the card is the My Number card 10M. Furthermore, the processor 110 may determine that the card is the My Number card 10M if the information in a specific area of ​​the IC chip 11 of the My Number card 10M, which can be accessed without access information such as a PIN or a verification number obtained via the IC reader 170, contains information indicating the My Number card 10M. Here, it has been described that the My Number card 10M is identified, but the processor 110 may also be used to identify a driver's license, passport, basic resident register card, etc., in addition to the My Number card 10M.

[0039] If the card 10 is an Individual Number card 10M, the processor 110 determines whether the captured side of the Individual Number card 10M is the front side FS or the back side BS (S12). For example, if the front side FS is captured, a facial image is included in the captured card image, so the processor 110 may determine that the captured side of the Individual Number card 10M is the front side FS if the captured card image includes a facial image. Furthermore, the processor 110 may determine that the captured side is the front side FS if, for example, information obtained by performing OCR processing on the captured card image includes specific information that can identify the front side FS.

[0040] In step S12, if the captured face of the My Number card 10M is the front face FS, that is, if the user UR holds up the photo face of the My Number card 10M, the processor 110 performs OCR processing on all or part of the captured card image (for example, a specific position on the front face FS that includes the number that constitutes the verification number B) to obtain the verification number B (S13). The contactless communication antenna 171 of the card reading device 100 transmits the verification number B as access information to the My Number card 10M. At this time, the card reading device 100 designates which application AP of the applications AP included in the My Number card 10M to transmit the access information to and transmits it. The contactless communication antenna 12 of the My Number card 10M receives the verification number B. The IC chip 11 enables the card reading device 100 to obtain information corresponding to the application AP to which the verification number B is to be transmitted. For example, if verification number B is acquired and transmitted to the card face AP, it becomes possible to acquire a card face image including a facial image and a facial image, and if verification number B is transmitted to the card face information input assistance AP, it becomes possible to acquire the My Number and four information as text data and their electronic signature data. Then, card reader 100 acquires the information that has become available by verification number B and application AP via non-contact communication antenna 12.

[0041] The processor 110 acquires a face image (also referred to as a card-captured face image) included in the card-captured image by cutting out a face image portion from the card-captured image (S14). The processor 110 acquires a face image (also referred to as a card-face image) obtained from the IC chip 11 using the verification number B (S14). The processor 110 acquires a face image (also referred to as a card-face image) of the user UR using the card reading device 100, captured by the face imaging unit 150 (S14). At this time, if the processor 110 can acquire the card-face image from the IC chip 11, acquisition of the card-captured face image may be omitted. The processor 110 authenticates the user UR (identity authentication) by performing face authentication using the card-face face image and the user face image (S14). As a face authentication method, for example, the processor 110 compares face feature amounts generated from the card-face face image and the user face image, respectively, or directly compares the card-face face image and the user face image. The facial authentication method is not limited to a specific method as long as it can determine whether the face image on the card and the user face image are of the same person. If the face image on the card cannot be acquired, the processor 110 authenticates the user UR (identity authentication) by performing face authentication using the captured face image on the card and the user face image. If the processor 110 has acquired three images, the captured face image on the card, the face image on the card, and the user face image, it may perform face authentication using the three images. Then, the processor 110 determines whether the identity authentication (S14) has been successful (S15).

[0042] If the identity authentication is successful in step S15, that is, if the user UR is the person identified by the My Number on the My Number card 10M, the contactless communication antenna 171 of the card reading device 100 transmits information indicating that the identity authentication was successful (identity authentication success information) to the My Number card 10M. The contactless communication antenna 12 of the My Number card 10M receives the identity authentication success information. The IC chip 11 transmits the four pieces of information held in the IC chip 11 to the card reading device 100 via the contactless communication antenna 12 based on the verification number B and the identity authentication success information. The contactless communication antenna 171 of the card reading device 100 acquires the four pieces of information from the IC chip 11 of the My Number card 10M (S16). The processor 110 may also display information indicating that the acquisition of the four pieces of information was successful via the display 140 (S17).

[0043] If the personal authentication fails in step S15, the processor 110 stops acquiring the four pieces of information (S18). In this case, the processor 110 may display information indicating that the personal authentication has failed via the display 140. In addition, in this case, the processor 110 may display information requesting the user UR to enter a PIN code via the display 140. In addition, in this case, a face-to-face interaction or the like may be performed.

[0044] In step S12, if the captured face of the My Number card 10M is the back face BS, that is, if the user UR holds up the number face of the My Number card 10M, the process proceeds to FIG. 4B, where the processor 110 performs OCR processing on all or part of the captured card image (for example, a specific position on the back face BS where the My Number is written) to obtain the verification number A (S21). At this time, the verification number A may be obtained by restoring a two-dimensional barcode included in the captured card image. The contactless communication antenna 171 of the card reading device 100 transmits the verification number A to the My Number card 10M as access information. At this time, the card face AP included in the My Number card 10M is transmitted as the transmission destination. The contactless communication antenna 12 of the My Number card 10M receives the verification number A. The IC chip 11 acquires the verification number A and transmits the verification number A to the card face AP, thereby enabling the card reading device 100 to acquire the card face image and the facial image, including the facial image obtained from the IC chip 11, via the contactless communication antenna 12. The contactless communication antenna 171 of the card reader 100 accesses the card face AP to acquire the card face image including the face image and the face image from the IC chip 11.

[0045] The processor 110 acquires a face image (card captured face image) included in the card captured image by cutting out a face image portion from the card captured image (S22). The processor 110 acquires a face image (card face image) obtained from the IC chip 11 (S22). The processor 110 acquires a face image (card face image) obtained by capturing an image of the face of the user UR using the card reading device 100 captured by the face imaging unit 150 (also referred to as a user face image). (S22) At this time, if the processor 110 can acquire the card face image from the IC chip 11, acquisition of the card captured face image may be omitted. The processor 110 authenticates the user UR (identity authentication) by comparing the user face image with the card face image and performing face authentication (S22). Examples of face authentication methods include comparing face feature amounts generated from the card face image and the user face image, respectively, or directly comparing the card face image and the user face image. The facial authentication method is not limited to a specific method as long as it can determine whether the face image on the card and the user face image are of the same person. If the face image on the card cannot be acquired, the processor 110 authenticates the user UR (identity authentication) by performing face authentication using the captured face image on the card and the user face image. If the processor 110 has acquired three images, the captured face image on the card, the face image on the card, and the user face image, it may perform face authentication using the three images. Then, the processor 110 determines whether identity authentication has been successful (S23).

[0046] If the personal authentication fails in step S23, the processor 110 stops obtaining the four pieces of information (S18 in FIG. 4A).

[0047] If the identity authentication is successful in step S23, that is, if the user UR is the person identified by the My Number on the My Number card 10M, the processor 110 performs OCR processing on the acquired card face image to acquire the four pieces of information written on the front FS of the My Number card 10M included in the card face image (S24, S25). The processor 110 determines whether the acquisition of the four pieces of information was successful through the OCR processing (S26). If the acquisition of the four pieces of information was successful through the OCR processing, the processor 110 may display information indicating that the acquisition of the four pieces of information was successful via the display 140 (S17 in FIG. 4A). In this way, the card reading device 100 can ensure greater reliability by acquiring the four pieces of information from the card face image acquired from the IC chip 11 than by acquiring the four pieces of information from a captured card image. This is because it is much more difficult to tamper with the card face image included in the IC chip 11 than to tamper with the card face. In S24 and S25, the card reading device 100 acquires the four pieces of information written on the front FS of the My Number card 10M included in the face image. However, the card reading device 100 may also acquire a verification number B and use the verification number B to access the face information input assistance AP to acquire the four pieces of information and their corresponding electronic signature data as text data. Specifically, the card reading device 100 performs OCR processing on the face image of the front FS to acquire the verification number B written on the face of the My Number card 10M included in the face image, and then accesses the face information input assistance AP using the acquired verification number B to acquire the four pieces of information and their corresponding electronic signature data as text data. In this way, the card reading device 100 can acquire not only the four pieces of information but also the electronic signature data linked to the four pieces of information.

[0048] If the acquisition of the four pieces of information by OCR processing fails in step S25, or if the user wishes to acquire the four pieces of information as text data from the card without performing OCR processing, the process proceeds to Fig. 4C, where the processor 110 requests a PIN code (for example, a PIN for assisting in inputting card information) from the user UR (S31). In this case, the processor 110 may display information requesting the user UR to enter a PIN code via the display 140 (S31). The user UR may confirm the display of the information requesting the user UR to enter a PIN code and enter the PIN code via the operation panel 130.

[0049] The processor 110 acquires the four pieces of information from the My Number card 10M based on the PIN code (S32). In this case, the contactless communication antenna 171 of the card reading device 100 transmits the PIN code to the My Number card 10M as access information. The contactless communication antenna 12 of the My Number card 10M receives the PIN code. If the IC chip 11 can provide the four pieces of information stored in the IC chip 11 based on the PIN code acquired from the contactless communication antenna 12 (for example, if the PIN code is correct), the IC chip 11 transmits the four pieces of information to the card reading device 100 via the contactless communication antenna 12. When the four pieces of information are provided from the IC chip 11, the contactless communication antenna 171 of the card reading device 100 acquires (receives) the four pieces of information.

[0050] The processor 110 determines whether or not the acquisition of the four pieces of information using the PIN code was successful (S33). If the acquisition of the four pieces of information using the PIN code was successful, the processor 110 may display information indicating that the acquisition of the four pieces of information was successful via the display 140 (S17 in FIG. 4A). On the other hand, if the acquisition of the four pieces of information using the PIN code was unsuccessful, the processor 110 may display information indicating that the acquisition of the four pieces of information was unsuccessful via the display 140 (S34). This allows the user UR to refer to what to do next. Depending on the settings of the card reading device 100, the processor 110 may request input of a PIN code (S31) when the card is placed on the placing base 101, and acquire the four pieces of information based on the PIN code (S32 to S34).

[0051] 4A to 4C, even when the card reading device 100 reads the card face image and the four pieces of information from the IC chip 11 of the My Number card 10M, the user UR does not need to insert the My Number card 10M in a specified orientation into the card reading device 100. Even in this case, the card reading device 100 can read (obtain) the four pieces of information with high reliability when the face of the My Number card 10M imaged by the card imaging unit 160 is the front face FS, and can read (obtain) the four pieces of information with reduced reliability when the face of the My Number card 10M is the back face BS.

[0052] In addition, when the surface of the My Number card 10M is the back surface BS in step S12 of Fig. 4A, only one of the processes of Fig. 4B or Fig. 4C may be performed. That is, the processes of steps S21 to S26 of Fig. 4B may be omitted, or the processes of steps S31 to S34 of Fig. 4C may be omitted.

[0053] Instead of displaying each piece of information, processor 110 may present each piece of information by a method other than display, for example, by outputting the information as sound from a speaker or the like.

[0054] When a PIN code is requested in step S18 of FIG. 4A, the four pieces of information may be obtained using the PIN code as in steps S31 to S34 of FIG. 4C.

[0055] Although the card reading device 100 acquires the four pieces of information after personal authentication, it may also acquire the four pieces of information without performing personal authentication. In this case, the card reading device 100 may acquire the four pieces of information directly and make them available for use, but it may also be possible to restrict the use (e.g., recording, display, transmission) of the four pieces of information before personal authentication, and then make the four pieces of information available for use after personal authentication.

[0056] When the verification number A is acquired, the processor 110 may acquire the My Number (verification number A) using a two-dimensional code instead of performing OCR processing on the captured image of the card. This is because the My Number printed on the back side BS is difficult to recognize as characters using OCR processing.

[0057] In this way, the card reading device 100 of this embodiment can determine information that can be obtained from the IC chip 11 of the My Number card 10M based on the captured card image or information input to the operation panel 1130. The card reading device 100 can directly obtain the four pieces of information as personal information from the IC chip 11, or can obtain the four pieces of information based on the card face image stored in the IC chip 11. The IC chip 11 can communicate contactlessly with the IC reader 170 when the My Number card 10M is positioned within the contactless wireless communication range of the IC reader 170, regardless of the orientation or posture of the My Number card 10M relative to the card reading device 100 (e.g., the mounting base 101). Therefore, the card reading device 100 can obtain the four pieces of information stored in the My Number card 10M regardless of whether the My Number card 10M is placed face up or down relative to the mounting base 101, or regardless of the orientation along the surface of the mounting base 101.

[0058] Furthermore, even when the My Number card 10M is placed on the mounting base 101 with the back surface BS facing up, the card reading device 100 can acquire the four pieces of information based on the access information (e.g., verification number A) included on the back surface BS. Therefore, the card reading device 100 does not need to mechanically flip the front surface FS and the back surface BS, and can quickly read (acquire) the My Number card 10M.

[0059] Furthermore, even when the user UR holds the My Number card 10M with the back BS facing up (places it on the placing stand 101), the IC chip 11 can acquire the card surface images of the front FS and back BS along with the My Number. Therefore, a facial image can be acquired from the card surface image to perform identity authentication, and the four pieces of information can be acquired from the card surface image by OCR processing or the like. In this case, acquiring the four pieces of information based on the card surface image obtained from the IC chip 11 is more reliable than acquiring the four pieces of information by OCR processing or the like on the captured card image. This is because the My Number card 10M captured by the card imaging unit 160 may have been tampered with (for example, by rewriting characters, replacing a photo, or replacing the entire surface with a sticker or the like). Furthermore, if the characters on the front FS or back BS of the My Number card 10M are difficult to recognize due to deterioration, there is a possibility that the front FS or back BS of the My Number card 10M may be misrecognized during OCR processing of the front FS or back BS. On the other hand, the image of the face of the card stored in the IC chip 11 is highly reliable because if the data is tampered with, the tampering can be detected by, for example, destroying the data or invalidating the digital signature.

[0060] Furthermore, if the IC chip 11 is soiled or damaged, if the non-contact communication antenna 12 is damaged, or if the IC chip 11 is locked, it may be impossible to acquire the card face image stored in the IC chip 11. In this case, the processor 110 may acquire information (e.g., text information) contained in the captured card image by performing OCR processing on the captured card image, although this information is less reliable than the information acquired from the IC chip 11.

[0061] The card reading device 100 is used in various situations where any card (for example, My Number card 10M) is used, and may be used in situations such as distribution, reception, lockers, and cash registers (for example, self-checkouts).

[0062] In the present embodiment, the IC reader 170 performs contactless wireless communication with the My Number card 10M, but this is not limiting. For example, if the card imaging unit 160 located at any position can capture an image of the front side FS or back side BS of the My Number card 10M, the IC reader 170 may be a contact-type IC reader that comes into contact with the card 10 to read information from the card 10.

[0063] Although various embodiments have been described above with reference to the drawings, it goes without saying that the present invention 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 invention. Furthermore, the components of the above-described embodiments may be combined in any manner without departing from the spirit of the invention.

[0064] In the above embodiments, the processor may be physically configured in any manner. Furthermore, if a programmable processor is used, the processing content can be changed by changing the program, thereby increasing the degree of freedom in processor design. The processor may be configured as a single semiconductor chip, or may be physically configured as multiple semiconductor chips. When configured as multiple semiconductor chips, each control in the above embodiments may be realized by a separate semiconductor chip. In this case, these multiple semiconductor chips can be considered to constitute a single processor. Furthermore, the processor may be configured as a semiconductor chip and a component (such as a capacitor) having a different function. Furthermore, a single semiconductor chip may be configured to realize both the function of the processor and other functions. Furthermore, multiple processors may be configured as a single semiconductor chip.

[0065] The order of execution of each process, such as operations, procedures, steps, and stages, in the devices, systems, programs, and methods shown in the claims, specifications, and drawings, is not specifically stated as "before," "prior to," etc., and can be realized in any order unless the output of a previous process is used in a subsequent process. Even if the operational flow in the claims, specifications, and drawings is explained using "first," "next," etc. for convenience, this does not mean that it is essential to perform the process in that order.

[0066] (Outline of the embodiment) As described above, the card reading device 100 of the above embodiment reads information from the My Number card 10M. The card reading device 100 includes an IC reader 170 (an example of an IC reading unit) that reads information from the IC chip 11 of the My Number card 10M, a card imaging unit 160 (an example of a first imaging unit) that images the My Number card 10M, and a processor 110 (an example of a control unit) that controls the IC reader 170. Based on the image captured by the card imaging unit 160, the processor 110 determines whether the face of the My Number card 10M imaged by the card imaging unit 160 is the front face FS or the back face BS. If the face of the My Number card 10M is the back face BS, the processor 110 obtains a card face image of the My Number card 10M from the IC chip 11 via the IC reader 170 and obtains information based on the card face image.

[0067] As a result, even when the back surface BS of the My Number card 10M is imaged, the card reading device 100 can obtain a card face image from the IC chip 11, and can obtain the four pieces of information by performing OCR processing on the card face image, etc. Even in this case, the card face image is information stored in the IC chip 11, so the four pieces of information can be obtained with high reliability. In this way, the card reading device 100 can quickly read personal information stored on the My Number card 10M even when the user UR presents the back surface BS of the My Number card 10M as the reading side, rather than the front surface.

[0068] Furthermore, when the face of the My Number card 10M is the front face, the processor 110 may obtain four pieces of information including the name, address, date of birth, and gender from the IC chip 11 via the IC reader 170.

[0069] As a result, when the front surface FS of the My Number card 10M is imaged, the card reading device 100 can directly obtain the four pieces of information from the IC chip 11, thereby obtaining highly reliable, tamper-free information. Furthermore, the card reading device 100 can obtain personal information without depending on the orientation of the My Number card 10M relative to a predetermined position on the card reading device 100. Therefore, the user UR does not need to insert the face of the My Number card 10M in a specified direction or place it in a specified orientation or orientation. In this way, the card reading device 100 can quickly read personal information stored on the My Number card 10M without the user UR having to be aware of the front and back of the My Number card 10M.

[0070] The card reading device 100 may further include a face imaging unit 150 (an example of a second imaging unit) that captures an image of the face of the user UR who uses the My Number card 10M. The processor 110 may perform identity authentication using the face image of the user UR captured by the face imaging unit 150 and the face image acquired from the My Number card 10M. If the user UR is authenticated as the identity of the individual, and if the face of the My Number card 10M is the front FS, the processor 110 may acquire four pieces of information from the IC chip 11 via the IC reader 170. If the user UR is authenticated as the identity of the individual, and if the face of the My Number card 10M is the back BS, the processor 110 may acquire a card face image of the My Number card 10M from the IC chip 11 via the IC reader 170, and acquire four pieces of information based on the card face image.

[0071] As a result, the card reading device 100 can permit the acquisition of the four pieces of information only when it is authenticated that the user UR is the person identified by the My Number card 10M. For example, if the age on the card is simply verified, there is a risk of impersonation. In contrast, the card reading device 100 can acquire personal information (e.g., the four pieces of information) held on the My Number card 10M with high security by combining identity authentication using facial recognition with card reading.

[0072] The card reading device 100 may further include an operation panel 130 (an example of an operation unit) that accepts input from a user UR who uses the My Number card 10M. If the face of the My Number card 10M is the back side BS and the processor 110 fails to acquire the four pieces of information based on the card face image, the processor 110 may acquire a code (e.g., a PIN code or personal identification number) input via the operation panel 130 and acquire the four pieces of information from the My Number card 10M based on the code.

[0073] As a result, even if the card reading device 100 fails to obtain the four pieces of information using the card face image, it can still obtain the four pieces of information using the code. In other words, the card reading device 100 can obtain personal information from the My Number card 10M in two stages.

[0074] Furthermore, the processor 110 may determine whether or not the card 10 placed at a predetermined position is a My Number card 10M. If the card 10 is a My Number card 10M, the processor 110 may determine whether the surface of the My Number card 10M imaged by the card imaging unit 160 is the front surface FS or the back surface BS.

[0075] This allows the card reading device 100 to read cards 10 other than My Number card 10M, and if it is determined to be a My Number card 10M, it can carry out processing to obtain personal information held by the My Number card 10M.

[0076] Furthermore, when the surface of the My Number card 10M is the front surface FS, the processor 110 may acquire the verification number B of the My Number card 10M based on the image (captured card image). The processor 110 may access the IC chip 11 using the verification number B via the IC reader 170 to acquire the information.

[0077] This allows the card reading device 100 to obtain the verification number B printed on the surface FS of the My Number card 10M by OCR processing, etc. Therefore, when the user UR places the My Number card 10M in a predetermined position, the card reading device 100 can automatically obtain four pieces of highly reliable information.

[0078] Furthermore, when the face of the My Number card 10M is the back side BS, the processor 110 may acquire the verification number A of the My Number card 10M based on the image. The processor 110 may access the IC chip 11 with the verification number A via the IC reader 170 to acquire the card face image.

[0079] This allows the card reading device 100 to obtain the verification number A printed on the back surface BS of the My Number card 10M by OCR processing, etc. Therefore, when the user UR places the My Number card 10M in a predetermined position, the card reading device 100 can automatically obtain a highly reliable card image. [Industrial Applicability]
