Description

The present invention is a SIM adapter that uses a contact or a SIM having both contact and non-contact functions in a detachable manner. In particular, the main body includes one or a plurality of USB receiving sockets for connecting USB devices. The present invention relates to a SIM adapter.
When such a SIM adapter is connected to a personal computer (hereinafter also referred to as “PC”) with a SIM attached, a biometric sensor such as a fingerprint sensor is connected to a USB receiving socket. It can be used for purposes such as authentic access authority authentication. Accordingly, the technical field of the present invention relates to the field of manufacture and use of SIM adapters.

In recent years, mobile phones have incorporated security ID modules called SIM (Subscriber Identity Module), UIM, and USIM (Universal SIM) cards, which are small IC cards, and are also incorporated in the latest mobile phones in Japan. Already put into practical use.
A UIM (User Identity Module) is an IC card in which contractor information issued by a mobile phone company is recorded, and is incorporated in a mobile phone and used to identify a user. For example, a UIM is considered to be inserted into an American cdma2000 mobile phone and receive an international roaming service.

On the other hand, SIM adapters and SIM readers / writers that are used with the SIM or UIM attached are also being used. For this, a contact type SIM or UIM, or a SIM or UIM having both contact and non-contact functions is used. The latter includes a contact defined by ISO 7816-2 and ISO 7816-3 and a non-contact interface defined by ISO 14443.
Furthermore, a dual interface IC card with USB (Universal Serial Bus) contact has been developed (Patent Document 1). An IC card having a USB interface facilitates connection with a USB compatible device such as a personal computer, and has begun to attract attention as an ID card for network access such as an employee ID card.

The applicant of the present application has previously proposed a SIM holder with a USB connector having a contact defined in ISO 7816-2 and ISO 7816-3 and a non-contact interface of ISO 14443 in Patent Document 2.
Patent Documents 3 and 4 propose a SIM reader / writer with a liquid crystal display.

11A and 11B are diagrams showing a SIM reader / writer with a liquid crystal display, in which FIG. 11A is a perspective view and FIG. 11B is a cross-sectional view taken along line AA in FIG.
As shown in FIG. 11A, the SIM reader / writer 1S with a liquid crystal display has a liquid crystal display 4 on the surface of the main body, and can display various information held by the SIM 2. In addition, the USB connector 20 is provided on the left side, and the insertion slot 15 for the SIM 2 is provided on the right side. The SIM 2 can be inserted from the insertion port 15 along the step portion 16. If the USB connector 20 is provided, access authority authentication can be performed by inserting the USB connector 20 into a PC or the like with the SIM 2 mounted, and data exchange with the PC can be started after authentication.
The LED display 14 indicates whether or not the power is on, and the switch button 9 is used for power on / off, display selection, operation determination, and the like.

As shown in FIG. 11B, the SIM 2 inserted from the right side of the SIM reader / writer is stopped and fixed below the terminal board 12. Usually, the SIM reader / writer 1S is composed of an upper lid portion 18 and a lower case portion 19 and has an antenna coil and a battery for non-contact communication therein, although not shown. The antenna coil is connected to the C4 and C8 terminals of the contact terminal plate 2t of the SIM 2 through the terminal plate 12.
In the claims and the following description of the present specification, SIM is a generic term for IC cards including UIM and USIM.
In addition, although expressed as a SIM adapter in the present invention, the appearance and function itself are the same as those of the SIM reader / writer 1S of Patent Document 4.

By the way, with the digitization of information and the development of networks, security that prevents information in information processing apparatuses from leaking to outsiders has become important. In order to ensure this security, a SIM reader / writer equipped with a SIM and having a USB connector is connected to a PC or the like to authenticate the person.
Conventionally, passwords, IDs, and passwords are used for this personal authentication. However, storing passwords, IDs, and passwords and entering keys is a burden on the user. . In addition, passwords, IDs, and passwords may be leaked to others.
Therefore, as an alternative to passwords, IDs, and passwords, authentication is performed using fingerprints, face information, or voiceprints or vein information, which are biometric information (biological information) that only the person can have. It is coming.

In Patent Document 5, for the purpose of obtaining such authentication information, an information processing apparatus is provided with an extended function that allows a biometric sensor such as a fingerprint sensor to be connected. There is a place to do. However, it is not described that a USB receiving socket is provided in the extended function unit itself as in the present application.
Patent Document 6 proposes an IC card reader / writer that is not portable, but has a plurality of USB receiving sockets and reads IC card data.

JP-T-2002-525720 Japanese Patent Application No. 2002-284825 Japanese Patent Application No. 2003-046656 Japanese Patent Application No. 2003-0466657 Japanese Patent Laid-Open No. 2001-126662 Japanese Patent Application No. 2003-055150

By the way, when the SIM is mounted on the SIM reader as described above and connected to a portable information processing device such as a notebook personal computer, a fixed information processing device such as a desktop personal computer, or a device for a specific purpose, The number of USB interface receiving sockets is usually about 1 to 4, and since it is already connected to a mouse or the like, all of the receiving sockets may be used.
In such a case, when considering a biometric collation in the SIM, or a biometric collation using a PC or a terminal by accumulating biometric data in the SIM, the biometrics corresponding to the SIM A sensor is required, and a receiving socket for USB is also required.
However, when there is no USB interface socket at the destination, biometrics collation cannot be performed.

  As described above, even if there is a shortage of spare USB sockets in the PC or special-purpose device to which the SIM reader / writer is connected and there is no USB interface socket, the biometrics The present invention has been completed by studying the form of a SIM adapter that can be verified and that does not impair practicality.

The SIM adapter of the present invention has the following effects.
(1) Portable PCs, PDAs (Personal Digital Assistants), mobile phones, and the like have a small number of USB receiving sockets mechanically, and if a SIM adapter is connected, the USB receiving sockets of the device may be occupied. Many users need to prepare and carry a USB interface socket for use without inconvenience. However, the SIM adapter of the present invention does not cause such a problem.

(3) When performing biometric authentication, without using a CPU such as a portable PC, PDA, or mobile phone, by performing biometric authentication using a biometric sensor connected to the receiving socket of the SIM adapter, Since biometric authentication can be performed without using the CPU or RAM of the above-described device, a usage method that reduces the risk of eavesdropping on biometric data becomes possible.
(4) Since it is not necessary to mount various biometric sensors on the SIM adapter and the sensor according to the purpose can be connected to the socket and used, the equipment of the SIM adapter itself can be reduced.

When biometrics matching is performed in the SIM, or when biometrics data is stored in the SIM and biometrics matching is performed on a PC or mobile terminal, a biometric sensor corresponding to the SIM is used. Necessary. That is, a fingerprint sensor for fingerprint collation, a camera for face collation, a vein sensor for vein collation, a pen pad for handwriting collation, a voiceprint collecting microphone for voiceprint, and the like.
However, by providing an interface connector (receiving socket) capable of connecting a plurality of these devices to the SIM adapter rather than a device in which each sensor is mounted on the SIM adapter to which the SIM is mounted, a multi-type or multi-function multi-function It is possible to operate a SIM that supports metrics authentication.
Of course, the provision of a USB interface in addition to the biometric sensor mounted on the SIM adapter is also effective as a backup for the authentication method, and is not excluded.

The SIM adapter of the present invention is broadly divided into one having only a USB interface conversion IC chip without a control IC chip (invention of claims 1 and 2) and one having a control IC chip (claim 3). The invention will be described in order with reference to the drawings.
1 is a block diagram of a first type SIM adapter, FIG. 2 is a block diagram of a second type SIM adapter, FIG. 3 is a diagram showing an example of a first type SIM adapter, and FIG. 4 is a second type SIM adapter. FIG. 5 is a diagram for explaining a usage state of the SIM adapter, and FIGS. 6 to 10 are diagrams for explaining a method of processing biometric data.

As shown in FIG. 1, the first form SIM adapter 1 </ b> A is a type including a USB interface conversion IC chip 10 without incorporating a control IC chip. Therefore, although it is a SIM adapter that reads / writes the SIM in appearance, it does not substantially include a CPU and functions as a hub device of a USB interface.
When the SIM adapter 1A is connected to a USB interface (I / F) 30I such as a PC, the SIM adapter 1A is connected to the SIM 2 via the USB hub controller 5 and the interface conversion IC chip 10. Further, one or a plurality of USB receiving sockets 8 for connecting external devices are directly connected to the USB hub controller 5.
The external device may be any device that can be connected to the USB serial bus. Although the present invention aims to connect a biometric sensor as described above, it is useful to be able to add a USB interface in addition to a biometric device. It is a feature of the product of the present invention to provide a hub function of a USB interface while having a SIM reading function.

The USB hub controller 5 refers to a dedicated LSI for a hub connected to the USB system. In general, it is known that a maximum of 127 devices can be connected to 6 layers via a hub controller. The interface conversion IC chip 10 is an IC chip for converting USB signal data (D +, D−) into ISO7816 data.
The first form SIM adapter 1A is classified into a case where a contact-type SIM is mounted (invention of claim 1) and a case of mounting both contact and non-contact SIMs (invention of claim 2).
The SIM 2 is attached to the interface conversion IC chip 10 via the terminal plate 12 of the SIM adapter 1A. When the antenna coil 11 is connected to the terminal plate 12, it is connected to the C4 and C8 terminals which are RFU (Revised for Future Use) terminals of the SIM2.

As shown in FIG. 2, the second-form SIM adapter 1B incorporates a control IC chip 3 and optionally includes a liquid crystal display 4, a fingerprint sensor 6, and a button 9.
The control IC chip 3 has a CPU and a memory, and also has an ISO 7816 driver and a liquid crystal driver for driving a liquid crystal display. It also functions as an interface conversion IC chip. However, not all of these are integrated into an IC chip.
Also in the case of the second embodiment, the USB hub controller 5 is indispensable. However, when the control IC chip 3 has the function, there is no need to provide it.

The signal of the SIM 2 is connected to the control IC chip 3 via the terminal plate 12 of the SIM adapter 1B and a relay (not shown).
Since the control IC chip 3 is provided, the fingerprint sensor 6 can be directly connected, and the reading data of the fingerprint sensor and the cardholder's biometric data such as the fingerprint data incorporated in the SIM 2 can be read and collated. If the liquid crystal display 4 is provided, the control is also performed. The control IC chip 3 also converts the USB signal data (D +, D−) into ISO7816 data.
In order to drive the liquid crystal display 4 and the fingerprint sensor 6, a battery (secondary battery) or an external power source 7 is required, and a charging circuit may be provided. The button 9 is used for selecting the display of the liquid crystal display 4 and determining the operation of the SIM 2.

As in the case of the first embodiment, one or a plurality of USB receiving sockets 8 for connecting external devices are connected via the control IC chip 3 and the USB hub controller 5. FIG. 2 shows three USB receiving sockets 8a, 8b, and 8c.
In the case of the second form, the SIM adapter 1B can function the biometric sensor or the like connected to the USB receiving socket 8 even if it is not connected to the USB interface (I / F) 30I such as a PC.
The second-type SIM adapter 1B also has a contact-type SIM (invention of claim 3, claim 5 and claim 7) and a contact / non-contact SIM (invention 4). 6, invention of claim 8). In the latter case, the antenna coil 11 is preferably provided.

3A and 3B are diagrams showing the first form SIM adapter, in which FIG. 3A is a plan view and FIG. 3B is a side view.
As shown in FIG. 3A, the first form SIM adapter 1A has a structure in which the SIM 2 can be detachably mounted, and includes a USB connector 20. The SIM 2 is inserted from the insertion port 15 and stops under the terminal board 12. At this position, the contact terminal plate of the SIM 2 and the terminal plate 12 of the SIM adapter 1 </ b> A are in contact via contact pins (not shown) of the terminal plate 12.
When the SIM2 is attached or detached, the SIM2 is pushed out by releasing the pin for fixing the SIM2, or the structure is formed so that the SIM2 can be pushed out.
The USB connector 20 is a male socket and is a terminal connected to a USB port of a PC or the like. It is known to have a power supply terminal (Vbus), a ground terminal (GND), and two data pins (D +, D-). The signals of the two data pins are converted into ISO7816 data by the interface conversion IC chip 10 and transmitted to the SIM2.

Bus power is supplied from the power supply terminal (Vbus). That is, when the USB connector is connected to a PC or the like, driving power can be supplied from the PC or the like. The USB standard defines that the USB cable supplies power in one direction in addition to transmitting data in both directions. It is usually assumed that a power supply of 5 VDC ± 5%, 500 mA is supplied. The USB standard also specifies that the connected device can have its own power supply. Such a device is called a power supply type device. On the other hand, an upstream device or a device that relies solely on power supplied from a hub is called a bus power supply type device.
Therefore, the SIM adapter 1A of FIG. 1 or FIG. 3 corresponds to a bus power supply type device, but it is necessary to provide a unique power source when connecting a sensor or the like that consumes more power than the power source to be supplied.
Since the SIM adapter 1B in FIG. 2 corresponds to a built-in power supply type device, the power supply of the external power supply 7 does not include bus power.

  When the SIM 2 includes both contact and non-contact interfaces, the SIM adapter 1A preferably includes the antenna coil 11 for non-contact communication. This is because even if the SIM 2 does not include an antenna coil, non-contact communication is possible.

As shown in FIG. 3B, the side surface of the SIM adapter 1A includes two USB receiving sockets 8a and 8b, which are female sockets for a USB interface. Of course, it may be one or more than two, but a large number of receiving sockets cannot be installed in the small SIM adapter 1A.
A fingerprint sensor, a vein sensor, or the like can be connected to the receiving sockets 8a and 8b according to the function of the SIM adapter 1A.

4A and 4B are diagrams showing the second form SIM adapter, in which FIG. 4A is a plan view and FIG. 4B is a side view.
As shown in the plan view of FIG. 4A, the second form SIM adapter 1B has a structure in which the SIM 2 can be detachably attached, and includes the USB connector 20, as in the first form. And a fingerprint sensor 6 and a button 9 are optionally provided.
When the SIM 2 includes both contact and non-contact interfaces, the SIM adapter 1B is preferably provided with the antenna coil 11 for non-contact communication.

  As shown in FIG. 4B, the side surface of the SIM adapter 1B includes three USB receiving sockets 8a, 8b, and 8c that are female sockets for the USB interface. However, the number may be one or two. Depending on the function of the SIM adapter 1B, for example, a voiceprint collecting microphone, a pen pad, a mouse, a hard disk drive, or the like can be connected to the receiving sockets 8a, 8b, 8c.

The USB connector 20 includes a series A (upstream), a series B (downstream), and a series mini-B (a small connector added to a portable device, downstream), but any of them may be used. . In general, it is assumed that a plug having a thickness of 4 mm, a width of 12 mm, and a protruding portion of about 12 to 13 mm is projected.
A USB hub controller 5 having a size of about 10 mm × 10 mm × 3 mm (for example, “Hub Controller Chip μPD72012” manufactured by NEC Corporation) is commercially available and practical.
There are two types of fingerprint sensors: a flat type that presses the fingertip against the sensor, and a sweep type that scratches the sensor surface with the fingertip. Either can be used, but the SIM adapter 1 is preferably a sweep type because the installation area is small and it is preferable for miniaturization. The sweep-type fingerprint sensor recognizes the characteristics of a fingerprint simply by rubbing a strip-shaped sensor surface with a width of several millimeters with a finger. Even if there is unevenness in the rubbing speed or pressing, the correction function works and a correct fingerprint pattern can be obtained.

The terminal board 12 of the SIM adapter 1 has a structure connected to 8 terminals of the contact terminal board provided in the SIM 2. The terminal board 12 is connected with the cable antenna coil 11 provided in the casing of the SIM adapter 1 to the C4 and C8 terminals which are spare terminals. The antenna coil 11 is for performing non-contact communication in conformity with ISO14443 Type A, B.
As the battery 7 of the SIM adapter 1, a lithium ion battery or a lithium polymer battery can be preferably used. If it is a lithium secondary battery, since the voltage of about 3.3-3.5V can be supplied, it is preferable in the electric power supply which drives an IC chip. As a supply voltage for the control IC chip 3, the liquid crystal display 4, and other system loads, about 3.3V may be secured.

The button 9 is used for power on / off, display selection, and operation determination. The liquid crystal display 4 is configured to sequentially display information held by the IC chip of the SIM 2 by operating the buttons 9.
As the liquid crystal display 4, a dot matrix type reflective color liquid crystal display can be adopted, and a graphic display is also possible. The thickness of the liquid crystal display 4 is about 1.0 mm to 1.5 mm. The display area can be from about 20 to 30 mm in width to about 40 to 70 mm in length.

  The outer shape of the SIM adapter 1 is manufactured by injection molding of polycarbonate resin or the like, and usually includes an upper lid portion and a lower case portion. The SIM 2 is inserted through the insertion port 15 that opens between the upper lid portion and the lower case portion, and stops at the lower surface of the contact terminal plate 12. Touch.

Next, a method for using the SIM adapter 1 will be described.
FIG. 5 is a diagram for explaining a usage state of the SIM adapter, and shows a state in which the SIM adapter 1 is connected to the notebook personal computer 30 and used. The personal computer is not limited to a notebook personal computer, and may be a desktop PC, a PDA, a portable terminal, or a dedicated terminal (ATM or the like).
With the SIM adapter 1 connected to the notebook computer 30, the fingerprint sensor 6 can collate with the fingerprint data of the person, and separately from the fingerprint collation or together with the fingerprint collation, the voice print collecting microphone connected to the USB receiving socket It shows that voiceprints can be collated and handwriting can be collated using a pen pad.

  The fingerprint sensor-installed SIM adapter 1 can perform fingerprint authentication processing in the SIM adapter 1 or in the SIM 2. By connecting another biometric sensor to the USB receiving socket 8 of the SIM adapter 1, the fingerprint authentication process can be performed. It is possible to authenticate voiceprints and handwritings other than those in the SIM adapter 1 or SIM2.

As described above, (1) SIM adapter 1 ← → hub ← → PC or PDA, the fingerprint can be authenticated in SIM adapter 1 or SIM2, but the other verification is PC And PDA must be routed in some form.
In other words, instead of the configuration of (1) above, (2) SIM adapter 1 ← → hub ← → configuration of a personal computer or PDA, in which a voice print collecting microphone or pen pad is connected to the personal computer or PDA hub Are the following processing methods (A), (B), and (C). When the biometric sensor is not connected to a personal computer or PDA hub, and the voiceprint sampling microphone or pen pad is connected only to the SIM adapter 1, the following processing methods (D) and (E) It becomes. Hereinafter, description will be given with reference to the drawings.

(A) [Internal verification of personal computer or PDA] (see FIG. 6)
In this case, the personal computer, PDA, etc. 30 reads the cardholder's biometric data (hereinafter also referred to as “BCD” in the figure) from the SIM 2 in the SIM adapter 1, and the personal computer, PDA RAM, etc. Temporarily store.
When the collator inputs raw (Live) biometric data using a biometric sensor 40 such as a voiceprint microphone or pen pad, it is temporarily recorded as temporary data in the RAM of a personal computer or PDA. The temporary data is analyzed by the personal computer, the PDA 30 or the like, and it is determined whether or not the temporary data can be used for biometric collation.

If available, reshape the data for biometric processing and extract biometric feature points. Next, the characteristic points of the data read from the SIM 2 and the raw (Live) biometric data (hereinafter also referred to as “BLD” in the figure) are compared and collated inside the personal computer or PDA 30. The biometric matching result is returned to the SIM 2 as “true” if the biometrics matching threshold is reached, and “false” if it is less.
If “true”, the biometrics collation status flag of SIM2 is changed.
In this case, since the cardholder's biometric data (BCD) and authenticity data flow through the USB connector 20 or remain in a memory such as a PC, there is a risk of eavesdropping. The SIM adapter 1 can be used to analyze and shape the signal by the biometric sensor 40 connected to the SIM adapter 1 by the PC 30, but the risk of eavesdropping is the same.

(B) [Verification by CPU in SIM adapter] (see FIG. 7)
The CPU of the SIM adapter 1 reads the cardholder's biometric data from the SIM 2 in the SIM adapter 1 and temporarily stores it in the RAM or the like of the SIM adapter 1.
When a biometric sensor 40 such as a voiceprint collecting microphone or pen pad connected to a personal computer or PDA 30 is used to input raw (live) biometric data, a temporary data is stored in the RAM of the personal computer or PDA 30. As a temporary recording. The temporary data is analyzed by the personal computer, the PDA 30 or the like, and it is determined whether or not the temporary data can be used for biometric collation.

If available, reshape the data for biometric processing and extract biometric feature points. Next, the feature point data is transmitted to the SIM adapter 1. The feature points of the data (BCD) read from the SIM 2 and the raw (Live) biometric data (BLD) are compared and collated by the CPU of the SIM adapter 1B. The biometric matching result is returned to the SIM 2 as “true” if the biometrics matching threshold is reached, and “false” if it is less. If “true”, the biometrics collation status flag of SIM2 is changed.
In this case, using the SIM adapter 1B, the signal of the biometric sensor 40 connected to the SIM adapter 1B can be used for analysis and shaping by a PC, PDA, or the like 30. However, in any case, there is a problem that the shaped biometric data (BLD) flows through the USB connector 20.

(C) [Verification by CPU in SIM] (see FIG. 8)
When a biometric sensor 40 such as a voiceprint collecting microphone or pen pad connected to a personal computer or PDA 30 is used to input raw (live) biometric data, a temporary data is stored in the RAM of the personal computer or PDA 30. As a temporary recording. The temporary data is analyzed by the personal computer, the PDA 30 or the like, and it is determined whether or not the temporary data can be used for biometric collation.
If available, format the data for biometric processing and extract biometric feature points. Next, the feature point data is transmitted to the SIM adapter 1. The SIM adapter 1 transmits the data to the SIM 2. The CPU in the SIM 2 compares and matches the pre-registered cardholder biometric feature point data (BCD) and the raw (live) biometric data (BLD) feature points. “True” if the biometrics collation threshold is reached, and “false” if less.
If “true”, the biometrics collation status flag of SIM2 is changed.
In this case, using the SIM adapter 1, the signal of the biometric sensor 40 connected to the SIM adapter 1 can be used for analysis / shaping by a PC, PDA, or the like 30. However, in any case, there is a problem that the shaped biometric data (BLD) flows through the USB connector 20.

(D) [Verification by CPU in SIM adapter] (see FIG. 9)
The CPU of the SIM adapter 1B reads the cardholder's biometric data from the SIM 2 in the SIM adapter 1B and temporarily stores it in the RAM or the like of the SIM adapter 1B. In this case, since the biometric sensor 40 is connected to the SIM adapter 1B, no CPU such as a PC or PDA is used.
When a collator inputs raw (Live) biometric data using a biometric sensor 40 such as a voiceprint microphone or pen pad, the data is temporarily recorded as temporary data in the RAM of the SIM adapter 1B. The SIM adapter 1B analyzes the temporary data and determines whether it can be used for biometric matching. If available, the data is shaped for biometric processing (no PC or PDA CPU is used in this process), and biometric feature points are extracted.
The feature points of the data (BCD) read from the SIM 2 and the raw (Live) biometric data (BLD) are compared and collated by the CPU of the SIM adapter 1B. The biometric matching result is returned to the SIM 2 as “true” if the biometrics matching threshold is reached, and “false” if it is less.
If “true”, the biometrics collation status flag of SIM2 is changed.

(E) [Verification by CPU in SIM] (see FIG. 10)
When a collator inputs raw (live) biometric data using a biometric sensor 40 such as a voiceprint microphone or pen pad, the data is temporarily recorded in the RAM of the SIM adapter 1 as temporary data. In this case, since the biometric sensor 40 is connected to the SIM adapter 1, no CPU such as a PC or PDA 30 is used.
The SIM adapter 1 analyzes the temporary data and determines whether it can be used for biometric matching. If available, the data is shaped for biometric processing (no PC or PDA CPU is used in this process), and biometric feature points are extracted. Next, the feature point data is transmitted to the SIM2. The CPU in the SIM 2 compares and matches the pre-registered cardholder biometric feature point data (BCD) and the raw (live) biometric data (BLD) feature points. “True” if the biometrics collation threshold is reached, and “false” if less.
If “true”, the biometrics collation status flag of SIM2 is changed.

  As described above, the processing method has been described in detail, but it is recognized that the processing method (A) has a risk of eavesdropping. However, when the CPU of the SIM adapter 1B is used or when processing is performed in the SIM 2, the risk does not occur. Furthermore, when processing is performed in the SIM adapter 1B or SIM2 using data of the biometric sensor 40 that the SIM adapter 1 has or is connected to the SIM adapter 1, there is no risk of data eavesdropping. it is obvious.

As described above, the present invention is suitably used for authority authentication in information security. However, the present invention is not limited to this application and can be applied to various applications requiring biometric authentication. For example, it can be used as a pass to a specific facility or as personal authentication when boarding an aircraft, and is not limited in terms of usage.
Although only a contact type and a contact / non-contact type SIM have been described as SIMs to be attached to the SIM adapter, as described in Document 1, an ISO 7816 contact and USB interface function IC card Has also been proposed.
Therefore, it is obvious to those skilled in the art that the SIM adapter of the present invention can be applied to the SIM having the function.
