It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. On the contrary, the invention is intended to cover alternatives, modifications, equivalents and alternatives which may be included within the spirit and scope of the invention as defined by the appended claims.

| C3 | VCC: supply voltage |

TABLE 1 Nano-SIM Pin definition
As shown in fig. 1, the two columns of left and right rows on the surface of the Nano-SIM card have 6 metal contacts, and the definition of the 6 metal contacts is shown in table 1, and the definition conforms to the ISO7816 communication standard protocol. The pins of the three-phase clock are defined as a CLK clock, a RST reset, a VCC power supply voltage, an IO input output, a VPP programming power supply and a GND ground signal from the first to the sixth in sequence.
In order to enable the Nano-SIM to realize the SD storage function, an SD protocol unit needs to be added on the basis of the original 7816 protocol unit, and the number of metal contacts for communication between the 7816 protocol unit and the SD protocol unit needs to be satisfied. The SIM mode operation at least needs the pin definitions of 5 metal contacts of a first metal contact CLK clock, a second metal contact RST reset, a third metal contact VCC supply voltage, a fourth metal contact IO input/output and a sixth metal contact GND ground signal, the CLK clock, the RST reset and the IO input/output must be independent pin definitions and cannot be shared with other protocol units, and the VCC supply voltage and the GND ground signal can be shared with other protocols; satisfying the SD mode operation requires at least DATA0 single-wire DATA transmission, and CLK clock, CMD command, VCC supply voltage and GND ground signals, and DATA0 single-wire DATA transmission, CLK clock, CMD command must be defined for independent pins, not shared with other protocol units, VCC supply voltage and GND ground signals can be shared with other protocols.
In the SIM mode, the CLK clock, the RST reset, the IO input/output cannot be occupied by other protocols, and the VCC supply voltage and the GND ground signal can be shared, so the third metal contact and the sixth metal contact of the SIM card can be multiplexed by the SD working mode, and the SD working mode also needs to redefine the pin definitions of the remaining 3 metal contacts. Because 6 metal contacts of the standard Nano-SIM card have 5 occupied contacts and only the fifth metal contact is left unused, the function of SIM + SD can be realized at the same time by at least expanding 2 contacts.
The invention provides a multifunctional SIM card, as shown in figure 2, the multifunctional SIM card comprises a 7816 protocol unit, an SD protocol unit, a control unit and a card interface; the control unit, the 7816 protocol unit and the SD protocol unit are arranged in the card body; the card interface is electrically connected with the 7816 protocol unit, the SD protocol unit and the control unit. As shown in fig. 3, the card interface includes n metal contacts disposed on a surface of the multifunctional security SIM card; the outline and the size of the multifunctional safety SIM card are the same as those of the existing standard Nano-SIM card, and the number of the contacts is different from that of the existing standard Nano-SIM card;
the n metal contacts of the card interface comprise a first metal contact, a second metal contact, a third metal contact, a fourth metal contact, a fifth metal contact, a sixth metal contact and n-6 expansion contacts; the layout of the first metal contact, the second metal contact, the third metal contact, the fourth metal contact, the fifth metal contact and the sixth metal contact (namely C1-C6) conforms to the pin definition of the ISO7816 protocol.
Furthermore, the n-6 expansion contacts at least comprise a first expansion contact and a second expansion contact, namely n is more than or equal to 8.
In an embodiment of the present invention, for convenience of illustration, n =8 is set, i.e. the embodiment is implemented based on 6 metal contacts +2 extension contacts of a standard Nano-SIM card, and the 2 extension contacts are C7 and C8. It should be noted that, in order to implement compatibility of multiple terminals, the position layouts of the first metal contact, the second metal contact, the third metal contact, the fourth metal contact, the fifth metal contact and the sixth metal contact in the present invention are consistent with the position layout of the existing standard Nano-SIM card, the positions of the extended contacts are located in other areas except the standard Nano-SIM card contact and are symmetrically arranged, so that the card interface can be accurately positioned, the number of the extended contacts can be 2, and the single-line data transmission function in the SD mode is implemented; 3 contacts can be added according to the requirement to realize the SD four-wire protocol, and the invention does not limit the number of the contacts as long as the number of the contacts does not affect the electrical performance of the card.
TABLE 2 multifunctional SIM card pin definitions
As shown in table 2, the multifunctional SIM card of the present invention employs a Nano-SIM card body, and 2 extension contacts are added in addition to the original 6 metal contacts, where C7 is a first extension contact and C8 is a second extension contact. And the pins of the SIM mode are defined as a first metal contact CLK, a second metal contact RST, a third metal contact VCC, a fourth metal contact VPP and a fifth metal contact GND, the pins of the SD mode are defined as a third metal contact VCC (multiplexed with the SIM mode), a fifth metal contact CLK, a sixth metal contact GND (multiplexed with the SIM mode), a first extension contact DATA0 and a second extension contact CMD. The definitions of the first extension contact and the second extension contact may be interchanged, where definition 1 in table 2 is a pin definition in the embodiment of the present invention, and definition 2 is a pin definition after the first extension contact and the second extension contact are interchanged.
The contact layout and pin definition are shown in fig. 4. Namely: the first metal contact is used for transmitting a CLK signal which can be identified by a 7816 protocol unit, the second metal contact is used for transmitting a RST signal which can be identified by the 7816 protocol unit, the fourth metal contact is used for transmitting an IO signal which can be identified by the 7816 protocol unit, and the fifth metal contact is used for transmitting a CLK signal which can be identified by an SD protocol unit; one of the first extension contact and the second extension contact is used for transmitting a CMD signal which can be identified by an SD protocol unit, the other two of the first extension contact and the second extension contact are used for transmitting a D0 signal which can be identified by the SD protocol unit, the third metal contact is used for transmitting a VCC signal which can be identified by the 7816 protocol unit and the SD protocol unit, and the sixth metal contact is used for transmitting a GND signal which can be identified by the 7816 protocol unit and the SD protocol unit.
Since CLK, RST, IO of SIM mode and CLK, CMD, DO of SD mode can all independently carry out signal transmission and DO not interfere with each other, and VCC and GND are shared in SIM mode and SD mode, therefore, SIM mode and SD mode can be guaranteed to work simultaneously.
As an embodiment of the present invention, the multifunctional SIM card includes a 7816 protocol unit, an SD protocol unit, a control unit, a card interface, and the control unit further includes a protocol identification unit, where the protocol identification unit is configured to identify a voltage value of the third metal contact and identify, according to the voltage value, whether a protocol corresponding to currently transmitted data is a 7816 protocol or an SD protocol.
As another embodiment of the present invention, since the card body of the multifunctional SIM card adopts a Nano-SIM card, the original 6 metal contacts can also be used as the Nano-SIM card alone, i.e. in a standard Nano-SIM mode; likewise, the 6 contacts of the multifunctional SIM card body plus 2 extension contacts can be utilized to independently realize the function of single-wire data transmission of the SD card, namely the standard SD mode.
Further, the multi-function SIM card may also be caused to switch between a standard Nano-SIM card mode and a standard SD mode. In order to realize the idea of the invention, the command of the upper computer needs to be identified, and then the protocol corresponding to the mode required by the upper computer is inquired. Therefore, the control unit of the multifunctional SIM card of the present invention may further include a protocol processing unit, where the protocol processing unit is built with a protocol supported by the multifunctional SIM card, and is configured to receive a command of the upper computer, and to avoid a conflict of protocol identification, the protocol processing unit needs to query a protocol required by the upper computer when the protocol identification unit is suspended.
Since the pin definition of the multi-functional SIM card in the default state only supports the SIM + SD simultaneous operation mode, the pin definition thereof cannot satisfy the standard Nano-SIM mode or the standard SD mode, and thus the pin definition needs to be reconfigured. In order to implement the above functions, the control unit of the multi-functional SIM card further includes a first pin configuration module, the first pin configuration module is internally provided with pin configuration policies of different protocols, and the control unit can configure the pin definitions of the metal contacts through the pin configuration policies, so that the multi-functional SIM card implements a protocol required by an upper computer.
It should be noted that the invention does not limit the pin definition of the card body metal contacts, so the metal contacts are all contacts that can be multiplexed by different protocols, thus a multi-protocol mode can be realized; or, the metal contacts are all contacts which can be reused by the same protocol, so that the one-card double-SIM mode or the one-card double-SD mode can be realized on the basis of adding the extension contacts and the processing unit.
As another embodiment of the present invention, the present invention further provides a terminal device, where the terminal device may be a mobile phone, a personal mobile digital assistant, a portable computer, a smart wearable device, and the like, as shown in fig. 5, the terminal device is provided with the above-mentioned multifunctional secure SIM card, and the terminal device is further provided with a card interface, a processing module, and a user interface, where the card interface may be inserted into the multifunctional SIM card or a standard Nano-SIM card, the card interface includes n elastic sheets, and n is greater than or equal to 6; the user interface is an interface between a user instruction and the processing module;
the multifunctional SIM card provided by the invention can be used in a standard Nano-SIM card slot and can also be used in the terminal equipment provided by the invention.
In the case that the terminal device is a standard Nano-SIM card slot, the card interface includes 6 elastic pieces, and in this case, the multifunctional SIM card of the present invention can be used, and a standard Nano-SIM card can also be used. The positions of 6 elastic sheets of the standard Nano-SIM card slot correspond to the positions of a first metal contact, a second metal contact, a third metal contact, a fourth metal contact, a fifth metal contact and a sixth metal contact of the multifunctional SIM card/the standard Nano-SIM card, so that signals can be read and processed;
in the case that the terminal device is a multifunctional SIM card slot, the card interface includes n elastic pieces, and in this case, the multifunctional SIM card of the present invention may be used, or a standard Nano-SIM card may be used. The positions of the n elastic sheets of the card interface correspond to the positions of the n metal contacts of the multifunctional SIM card, so that the multifunctional SIM card can be read and processed to realize the function of the multifunctional SIM card; the positions of 6 elastic sheets of the card interface correspond to the positions of 6 metal contacts of the standard Nano-SIM card, so that the function of the standard Nano-SIM card can be realized. Therefore, the multi-machine compatible function of the multi-function SIM card can be realized.
As another embodiment of the present invention, the terminal device provided by the present invention can perform switching of the multi-function SIM card mode. As shown in fig. 6, the processing module of the terminal device further includes a second pin configuration module, where the second pin configuration module is internally provided with a pin configuration policy of the card interface support protocol, and the pin configuration policy of the second pin configuration module can be identified and processed by the pin configuration module of the multifunctional security SIM card; when the user sends a command to the processing module through the user interface and selects the multifunctional SIM card mode required by the user, the second pin configuration module selects a pin configuration strategy according to the command to realize the working mode required by the user.
Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same, and those skilled in the art should make modifications to the specific embodiments of the present invention or make equivalent substitutions for part of technical features without departing from the spirit of the technical solutions of the present invention, and all of them should be covered in the technical solutions claimed in the present invention.
