[0035] Exemplary embodiments will be described in detail herein, examples of which are identified in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0036] Figure 1 is a schematic diagram of the structure of a memory card provided by the related art. The memory card is a Micro SD card, such as Figure 1 As shown, the Micro SD card is rectangular, and the side of the rectangular memory card has a protrusion 10 for distinguishing the direction, so that the memory card can be installed in the card holder in the correct posture direction. Among them, the memory card has 8 pins, and the order of the 8 pins from left to right is respectively a data transmission pin 11 (Data2), a data transmission pin 12 (Data3), a command / response pin 13 (Command / Response, CMD), a power signal pin 14 (Volt Current Condenser, VCC), a clock signal pin 15 (Clock), a ground signal pin 16 (ground, GND), a data transmission pin 17 (Data0) and a data transmission pin 18 (Data1). And the above 8 pins are arranged in the same direction. Among them, the size of the Micro SD card is 15.0*11.0*0.70mm (length a*width b*thickness).

[0037] Figure 2 : is a schematic diagram of the structure of a Nano-SIM card provided by the related technology. Figure 2As shown, the Nano-SIM card is rectangular, and the corner of the Nano-SIM card has a notch 20 for distinguishing the direction, so that the Nano-SIM card can be installed in the card holder in the correct posture direction. The Nano-SIM card has 6 pins, 3 pins in the upper half of the Nano-SIM card, and the order from left to right is the ground signal pin 24 (GND), the programming voltage signal pin 22 (Programming voltage, VPP) and the data transmission pin 25 (I / O), and the 3 pins are arranged in the same direction; there are 3 pins in the lower half of the Nano-SIM card, and the order from left to right is the power signal pin 21 (VCC), the reset signal pin 26 (Reset), and the clock signal pin 23 (Clock), and the 3 pins are arranged in the same direction. Among them, the size of the Nano-SIM card is 12.3*8.8*0.67mm (length a*width b*thickness).

[0038] Combination Figure 1 , 2 It can be seen that in the related art, the Micro SD card and the Nano-SIM card are different in appearance and size, which makes the Micro SD card unable to be compatible with the Nano-SIM card holder.

[0039] In order to make use of the space of the other Nano-SIM card holder of the two Nano-SIM card holders, the related art provides a memory card. Figure 3 1 is a schematic diagram of the structure of a memory card provided by the related art. Figure 3 As shown, the memory card is a NanoMemory card (NM card), which is rectangular in shape and has a notch at the corner for distinguishing the direction, so that the NM card can be installed in the card holder in the correct posture and direction. The NM card has the same shape and size as the Nano-SIM card, and the size of the NM card is also 12.3*8.8*0.67mm (length a*width b*thickness).

[0040] The NM card has 8 pins, 4 of which are in the upper half of the NM card, and the order from left to right is data transmission pin 12 (Data3), ground signal pin 16 (GND), command / reply pin 13 (CMD) and data transmission pin 18 (Data1), and the 4 pins are arranged in the same direction; the NM card has 4 pins in the lower half of the NM card, and the order from left to right is data transmission pin 11 (Data2), power signal pin 14 (VCC), data transmission pin 17 (Data0) and clock signal pin 15 (Clock), and the 4 pins are arranged in the same direction. Since the NM card has 8 pins, 2 more than the 6 pins of the Nano-SIM card, and the types of some pins are different from those of the Nano-SIM card, that is, the pins of the NM card and the Nano-SIM card are different in both quantity and type.

[0041] Although the NM card has the same dimensions as the Nano-SIM card, due to the difference in pins, two pins of the NM card cannot be electrically connected to the card holder, which results in the NM card still not being able to be used normally even after being installed in the Nano-SIM card holder. Therefore, when using the NM card, a Nano-SIM card holder on the terminal needs to be equipped with a new card holder, that is, the NM card in the related art can only solve the problem of making the space of the other Nano-SIM card holder of the two Nano-SIM card holders available. It cannot solve the problem of sharing the memory card with the Nano-SIM card holder.

[0042] To this end, an embodiment of the present disclosure provides a memory card, which includes a card body and a plurality of pins located on a surface of the card body, wherein the card body includes: a storage unit and a control unit located inside the memory card, the control unit is electrically connected to the storage unit and the pins respectively, and the shape and size of the memory card are the same as those of a Nano-SIM card.

[0043] Figure 4 FIG. 1 is a schematic diagram of a memory card according to an exemplary embodiment. Figure 4As shown, the multiple pins of the memory card include: a power signal pin 31, a command / reply pin 32, a clock signal pin 33, a ground signal pin 34, a first data transmission pin 35, and a second data transmission pin 36. The area of ​​the power signal pin 31 on the memory card corresponds to the area of ​​the power signal pin 21 of the Nano-SIM card on the Nano-SIM card, and the area of ​​the ground signal pin 34 on the memory card corresponds to the area of ​​the ground signal pin 24 of the Nano-SIM card on the Nano-SIM card. The area of ​​the command / reply pin 32 on the memory card corresponds to the area of ​​the first pin of the Nano-SIM card on the Nano-SIM card, the area of ​​the clock signal pin 33 on the memory card corresponds to the area of ​​the second pin of the Nano-SIM card on the Nano-SIM card, the area of ​​the first data transmission pin 35 on the memory card corresponds to the area of ​​the third pin of the Nano-SIM card on the Nano-SIM card, and the area of ​​the second data transmission pin 36 on the memory card corresponds to the area of ​​the fourth pin of the Nano-SIM card on the Nano-SIM card.

[0044] Among them, the first pin of the Nano-SIM card, the second pin of the Nano-SIM card, the third pin of the Nano-SIM card, and the fourth pin of the Nano-SIM card are different pins among the programming signal pin 22, the clock signal pin 23, the data transmission pin 25, and the reset signal pin 26 respectively.

[0045] Exemplarily, the region of a pin on the memory card corresponding to the region of a pin on the Nano-SIM card corresponding to the region of a pin on the Nano-SIM card may mean that the pin on the memory card and the pin on the Nano-SIM card are mapped to the same spring piece on the card holder. For example, the power signal pin of the memory card and the power signal pin of the Nano-SIM card correspond to the same spring piece on the card holder.

[0046] According to the above, there are many corresponding relationships between the first pin, the second pin, the third pin, and the fourth pin of the Nano-SIM card and the programming signal pin, the clock signal pin, the data transmission pin, and the reset signal pin of the Nano-SIM card. In addition, the number of permutations and combinations of the corresponding relationship between the programming signal pin, the clock signal pin, the data transmission pin, and the reset signal pin and the first pin, the second pin, the third pin, and the fourth pin can reach 4! = 24. The following only exemplifies several possible corresponding methods.

[0047] Optionally, the area of ​​the clock signal pin on the memory card corresponds to the area of ​​the clock signal pin of the Nano-SIM card on the Nano-SIM card, and the area of ​​the first data transmission pin on the memory card corresponds to the area of ​​the data transmission pin of the Nano-SIM card on the Nano-SIM card.

[0048] The area of ​​the command / reply pin on the memory card corresponds to the area of ​​one of the reset signal pin and programming voltage signal pin of the Nano-SIM card on the Nano-SIM card, and the area of ​​the second data transmission pin on the memory card corresponds to the area of ​​the other of the reset signal pin and programming voltage signal pin of the Nano-SIM card on the Nano-SIM card. That is, the following two implementation methods may be included:

[0049] The first type: the area of ​​the command / reply pin on the memory card corresponds to the area of ​​the programming voltage signal pin of the Nano-SIM card on the Nano-SIM card.

[0050] The second type: the area of ​​the second data transmission pin on the memory card corresponds to the area of ​​the reset signal pin of the Nano-SIM card on the Nano-SIM card.

[0051] In an exemplary embodiment of the present disclosure, that is, in the first implementation, the first pin corresponds to the programming voltage signal pin, the second pin corresponds to the clock signal pin, the third pin corresponds to the data transmission pin, and the fourth pin corresponds to the reset signal pin. Figure 4 As shown, the area of ​​the command / reply pin 32 on the memory card corresponds to the area of ​​the programming voltage signal pin 22 of the Nano-SIM card on the Nano-SIM card, the area of ​​the second data transmission pin 36 on the memory card corresponds to the area of ​​the reset signal pin 26 of the Nano-SIM card on the Nano-SIM card, the area of ​​the first data transmission pin 35 on the memory card corresponds to the area of ​​the data transmission pin 25 of the Nano-SIM card on the Nano-SIM card, and the area of ​​the clock signal pin 33 on the memory card corresponds to the area of ​​the clock signal pin 23 of the Nano-SIM card on the Nano-SIM card. In the memory card, four pins, namely, a power signal pin 31 (VCC), a ground signal pin 32 (GND), a clock signal pin 33 (Clock) and a first data transmission pin 35 (I / O1), are arranged in the same position as the same four pins on the Nano-SIM card, and the remaining second data transmission pin 36 (I / O2) and a command / reply pin 32 (CMD) are arranged in the same position as the reset signal pin 26 (Reset) and the programming voltage signal pin 22 (VPP) on the Nano-SIM card, respectively, thereby ensuring that the six pins on the memory card can all contact the corresponding six metal springs on the Nano-SIM card holder, thereby achieving adaptive installation of the memory card and the Nano-SIM card holder, and making the Nano-SIM card holder compatible with the memory card.

[0052] In another exemplary embodiment of the present disclosure, that is, in the second implementation, the first pin corresponds to the reset signal pin, the second pin corresponds to the clock signal pin, the third pin corresponds to the data transmission pin, and the fourth pin corresponds to the programming voltage signal pin. Figure 5 FIG. 1 is a schematic diagram of a memory card according to an exemplary embodiment. Figure 5 As shown, the area of ​​the second data transmission pin 36 on the memory card corresponds to the area of ​​the programming voltage signal pin 22 of the Nano-SIM card on the Nano-SIM card, the area of ​​the command / reply pin 32 on the memory card corresponds to the area of ​​the reset signal pin 26 of the Nano-SIM card on the Nano-SIM card, the area of ​​the first data transmission pin 35 on the memory card corresponds to the area of ​​the data transmission pin 25 of the Nano-SIM card on the Nano-SIM card, and the area of ​​the clock signal pin 33 on the memory card corresponds to the area of ​​the clock signal pin 23 of the Nano-SIM card on the Nano-SIM card. In the memory card, the power signal pin 31 (VCC), the ground signal pin 34 (GND), the clock signal pin 33 (Clock) and the first data transmission pin 35 (I / O1) are arranged in the same position as the same four pins on the Nano-SIM card, and the remaining second data transmission pin 36 (I / O2) and the command / reply pin 32 (CMD) are arranged in the same position as the programming voltage signal pin 22 (VPP) and the reset signal pin 26 (Reset) on the Nano-SIM card, respectively, thereby ensuring that the 6 pins on the memory card can all contact the corresponding 6 metal springs on the Nano-SIM card holder, realizing the adaptive installation of the memory card and the Nano-SIM card holder, so that the Nano-SIM card holder can be compatible with the memory card. Since the position of the memory card pins of this pin correspondence relationship is slightly changed and has a high consistency with the Nano-SIM card, it is easier to adapt to the Nano-SIM card holder and has a low cost.

[0053] Optionally, in some other exemplary embodiments of the present disclosure, the first pin corresponds to a data transmission pin, the second pin corresponds to a command / reply signal pin, the third pin corresponds to a programming voltage signal pin, and the fourth pin corresponds to a clock signal pin. Figure 6As shown, the area of ​​the first data transmission pin 35 on the memory card corresponds to the area of ​​the programming voltage signal pin 22 of the Nano-SIM card on the Nano-SIM card, the area of ​​the clock signal pin 33 on the memory card corresponds to the area of ​​the reset signal pin 26 of the Nano-SIM card on the Nano-SIM card, the area of ​​the command / reply pin 32 on the memory card corresponds to the area of ​​the data transmission pin 25 of the Nano-SIM card on the Nano-SIM card, and the area of ​​the second data transmission pin 36 on the memory card corresponds to the area of ​​the clock signal pin 23 of the Nano-SIM card on the Nano-SIM card. In the memory card, the power signal pin 31 (VCC) and the ground signal pin 34 (GND) are arranged in the same position as the same two pins on the Nano-SIM card, and the remaining first data transmission pin 35 (I / O1), clock signal pin 33 (Clock), command / reply pin 32 (CMD) and second data transmission pin 36 (I / O2) are arranged in the same position as the programming voltage signal pin 22 (VPP), reset signal pin 26 (Reset), data transmission pin 25 (I / O) and clock signal pin 23 (Clock) on the Nano-SIM card, respectively, thereby ensuring that the 6 pins on the memory card can all contact with the corresponding 6 metal springs on the Nano-SIM card holder, realizing the adaptive installation of the memory card and the Nano-SIM card holder, so that the Nano-SIM card holder can be compatible with the memory card.

[0054] For example, Figures 4 to 6 As shown, the memory card is rectangular, wherein the memory card has a first side 3a and a second side 3b opposite to each other, the first side 3a and the second side 3b are both short sides of the memory card, and the memory card has 6 pins, 3 of which are close to the first side 3a, and the 3 pins are arranged at intervals along the extension direction of the first side 3a; the remaining 3 of the 6 pins are close to the second side 3b, and the 3 pins are arranged at intervals along the extension direction of the second side 3b. A positioning chamfer 30 is provided at the connection between a side adjacent to the first side 3a on the memory card and the first side 3a, so that the memory card can be installed in the Nano-SIM card holder in the correct posture direction.

[0055] Optionally, along the direction of the first side 3a close to the positioning chamfer 30, the three pins close to the first side 3a are respectively a ground signal pin 34, a command / reply pin 32, and a first data transmission pin 35; along the direction of the first side 3a close to the positioning chamfer 30, the three pins close to the second side 3b are respectively a power signal pin 31, a second data transmission pin 36, and a clock signal pin 33.

[0056] Combination Figure 4, the three pins near the first side 3a are located in the upper half of the memory card, and the order from left to right (i.e., along the direction of the first side 3a close to the positioning chamfer 30) can be respectively a ground signal pin 34 (GND), a programming voltage signal pin 32 (Programming voltage, VPP) and a first data transmission pin 35 (I / O1), and the three pins are arranged along the extension direction of the first side 3a; the three pins near the second side 3b are located in the lower half of the memory card, and the order from left to right can be respectively a power signal pin 31 (VCC), a second data transmission pin 36 (I / O2), and a clock signal pin 33 (Clock), and the three pins are arranged along the extension direction of the second side 3b. The size of the memory card is 12.3*8.8*0.67mm (length a*width b*thickness).

[0057] Optionally, along the direction of the first side 3a close to the positioning chamfer 30, the three pins close to the first side 3a are respectively a ground signal pin 34, a second data transmission pin 36, and a first data transmission pin 35; along the direction of the first side 3a close to the positioning chamfer 30, the three pins close to the second side 3b are respectively a power signal pin 31, a command / reply pin 32, and a clock signal pin 33.

[0058] Combination Figure 5 , the three pins close to the first side 3a are located in the upper half of the memory card, and the order from left to right (i.e., along the direction of the first side 3a close to the positioning chamfer 30) can be a ground signal pin 34 (GND), a second data transmission pin 36 (I / O2) and a first data transmission pin 35 (I / O1), and the three pins are arranged along the extension direction of the first side 3a; the three pins close to the second side 3b are located in the lower half of the memory card, and the order from left to right can be a power signal pin 31 (VCC), a programming voltage signal pin 32 (VPP), and a clock signal pin 33 (Clock), and the three pins are arranged along the extension direction of the second side 3b.

[0059] Exemplarily, each pin on the memory card may be a metal contact sheet, and the metal contact sheet is used to contact with a metal spring sheet on the card holder, so as to connect the memory card to the circuit.

[0060] Optionally, the first data transmission pin and the second data transmission pin are both high-speed data transmission pins. Exemplarily, the first data transmission pin and the second data transmission pin may be I / O pins, which are high-speed channels. By increasing the transmission speed of a single data transmission pin, the transmission speed of four data transmission pins can be achieved by using two data transmission pins. While reducing the number of pins, the memory card and the Nano-SIM card holder can be compatible and easy to use.

[0061] For example, the total transmission speed of the four data transmission pins of the memory card with four data transmission pins in the related art may be 104M / s, and the transmission speed of each data transmission pin may be 26M / s. However, the transmission speed of a single high-speed data transmission pin of the high-speed data transmission pin used in the present disclosure may be 52M / s. That is, the transmission speed of a single high-speed data transmission pin is equivalent to the transmission speed of two data transmission pins, thereby achieving the transmission speed of four data transmission pins by using two data transmission pins.

[0062] Optionally, the power signal pin has the same shape and size as the power signal pin of the Nano-SIM card. The ground signal pin has the same shape and size as the ground signal pin of the Nano-SIM card. The command / reply pin, the clock signal pin, the first data transmission pin and the second data transmission pin have the same shape and size as the corresponding signal pins on the Nano-SIM card.

[0063] Among them, the command / reply pin, the clock signal pin, the first data transmission pin and the second data transmission pin are all the same in shape and size as the corresponding signal pins on the Nano-SIM card, which may include at least the following two cases:

[0064] The first one, such as Figure 4 As shown, the command / reply pin 32 on the memory card and the programming voltage signal pin 22 on the Nano-SIM card have the same shape and size, the second data transmission pin 36 on the memory card and the reset signal pin 26 on the Nano-SIM card have the same shape and size, and the first data transmission pin 35 on the memory card and the data transmission pin 25 on the Nano-SIM card have the same shape and size, and the clock signal pin 33 on the memory card and the clock signal pin 23 on the Nano-SIM card have the same shape and size;

[0065] The second type, such as Figure 5 As shown, the command / reply pin 32 on the memory card and the reset signal pin 26 on the Nano-SIM card have the same shape and size, the second data transmission pin 36 on the memory card and the programming voltage signal pin 22 on the Nano-SIM card have the same shape and size, and the first data transmission pin 35 on the memory card and the data transmission pin 25 on the Nano-SIM card have the same shape and size, and the clock signal pin 33 on the memory card and the clock signal pin 23 on the Nano-SIM card have the same shape and size.

[0066] Optionally, the pins of the memory card are rectangular. Figures 4 to 6In the memory card shown, the pins of the memory card are all rectangular and have the same size. By setting the shape and size of the pins on the memory card to be the same as the shape and size of the corresponding signal pins on the Nano-SIM card, it can be ensured to the greatest extent that after the memory card is installed in the Nano-SIM card holder, it can fully contact the spring on the Nano-SIM card holder, thereby ensuring the compatibility of the memory card and the Nano-SIM card holder.

[0067] It should be noted that the pins in the embodiments of the present disclosure may also be other shapes, such as circle, triangle, square, etc., wherein the area of ​​the pin may not be less than half of the area of ​​the corresponding pin on the Nano-SIM card, and the area of ​​the pin may not be larger than the area of ​​the corresponding pin on the Nano-SIM card, so as to ensure that the pin of the memory card is in full contact with the spring on the Nano-SIM card holder.

[0068] A brief process of data transmission between a memory card and a terminal provided by an exemplary embodiment of the present disclosure can be as follows: after the memory card is inserted into the Nano-SIM card holder, the power signal pin is powered on to supply power to the memory card and provide the memory card with electrical energy to meet its work, the ground signal pin is powered on to ground the memory card, and the clock signal pin is powered on to transmit a time signal. During operation, the command / reply pin can receive a control signal sent by the terminal, and the command / reply pin transmits the control signal to the control unit of the memory card. The control unit controls the two data transmission pins to perform data transmission with the terminal according to the control signal, including writing data into the memory card and reading data from the memory card.

[0069] The disclosed embodiment sets the shape and size of the memory card to be consistent with the shape and size of the Nano-SIM card so that the memory card can be inserted into the Nano-SIM card holder. At the same time, the pins of the memory card include: a power signal pin, a command / reply pin, a clock signal pin, a ground signal pin, a first data transmission pin and a second data transmission pin, a total of 6 pins, wherein the arrangement area of ​​the power signal pin and the ground signal pin corresponds to the corresponding pin arrangement area on the Nano-SIM card, and the arrangement area of ​​the command / reply pin, the clock signal pin, the first data transmission pin and the second data transmission pin in the memory card also corresponds to the arrangement area of ​​the remaining 4 pins of the 6 pins on the Nano-SIM card. Therefore, after the memory card is inserted into the Nano-SIM card holder, it can achieve one-to-one docking with the interface set on the card holder, so that the memory card can be adapted to the Nano-SIM card holder, so that the Nano-SIM card holder can be fully utilized.

[0070] In addition, in the embodiments of the present disclosure, in the embodiments where the position of the pins on the memory card is slightly changed, for example, Figure 4 , 5In the embodiment shown, since the memory card and the Nano-SIM card have a high consistency, it is easier to adapt to the Nano-SIM card holder and the cost is low.

[0071] The present disclosure provides a terminal including the memory card as described above, wherein the terminal may include various handheld devices with communication functions, vehicle-mounted devices, wearable devices, home smart devices, computing devices or other processing devices connected to a wireless modem, and various forms of terminals, such as smart phones, tablet computers, etc.

[0072] Exemplarily, the terminal may have one card holder or two card holders. When the terminal has one card holder, the card holder is used to install a memory card, such as a tablet computer. When the terminal has two card holders, at least one of the two card holders is used to install a memory card, such as a dual-SIM dual-standby smartphone, one of the two card holders can be used to install a Nano-SIM card, and the other card holder is used to install a memory card.

[0073] Since the memory card in the present disclosure is electrically connected to the terminal using a Nano-SIM card holder, the terminal needs to identify whether the card installed in the Nano-SIM card holder is a memory card or a Nano-SIM card before using the memory card. To this end, an embodiment of the present disclosure provides a memory card identification method.

[0074] Figure 7 FIG. 1 is a flow chart of a method for identifying a memory card according to an exemplary embodiment. Figure 7 As shown, the identification method can be executed by a control unit in the terminal, including:

[0075] In step 101, a detection signal is sent to a target pin of a card to be identified.

[0076] The card to be identified is a Nano-SIM card or the memory card mentioned above.

[0077] In step 101, the target pin includes at least one of a first target pin, a second target pin, a second target pin, and a fourth target pin. That is, sending a detection signal to the target pin of the card to be identified may include: sending a detection signal to at least one of the first target pin, the second target pin, the second target pin, and the fourth target pin of the card to be identified.

[0078] Among them, the areas of the first target pin, the second target pin, the third target pin and the fourth target pin on the card to be identified respectively correspond to different areas of the command / reply pin, the clock signal pin, the first data transmission pin and the second data transmission pin in the four areas of the memory card.

[0079] In the present disclosure, sending a detection signal to a target pin of a card to be identified may include the following four situations.

[0080] The first one is to send a detection signal to the first target pin, that is, the target pin is the first target pin.

[0081] The second method is to send a detection signal to the first target pin and the second target pin, that is, the target pins include the first target pin and the second target pin.

[0082] The third type is to send a detection signal to the first target pin, the second target pin and the third target pin, that is, the target pins include the first target pin, the second target pin and the third target pin.

[0083] A fourth type is to send a detection signal to a first target pin, a second target pin, a third target pin and a fourth target pin, that is, the target pins include the first target pin, the second target pin, the third target pin and the fourth target pin.

[0084] The detection signal may be a voltage signal. Exemplarily, the voltage value of the voltage signal may be 0.4V to 1.0V.

[0085] Optionally, voltage signals with the same or different voltage values ​​are sent to different target pins. For example, the voltage value of the voltage signal sent to the first target pin may be 0.4V, and the voltage value of the voltage signal sent to the second target pin may also be 0.4V; or, the voltage value of the voltage signal sent to the first target pin may be 0.4V, and the voltage value of the voltage signal sent to the second target pin may be 0.8V.

[0086] In step 102, a detection response signal fed back by a card to be identified is received from a target pin.

[0087] Since the card to be identified in the present disclosure is one of a memory card and a Nano-SIM card, the first target pin, the second target pin, the third target pin, and the fourth target pin may include a reset signal pin, a programming voltage signal pin, a data transmission signal pin, a clock signal pin, a command / reply pin, a clock signal pin, a first data transmission pin, and a second data transmission pin. When a detection signal is sent to the three pins of the reset signal pin, the programming voltage signal pin, and the command / reply pin, the three pins will all feedback different detection response signals. For example, the voltage values ​​of the detection response signals fed back by the reset signal pin, the programming voltage signal pin, and the command / reply pin are different. The feedback detection response signal will be transmitted to the terminal through the card holder and received by the control unit in the terminal; at the same time, the data transmission pin, the first data transmission pin, and the second data transmission pin are transmission channels, and the pin will not feedback the detection response signal after receiving the detection signal, and the clock signal pin will not feedback the detection response signal after receiving the detection signal, thereby providing the possibility of identifying the card to be identified.

[0088] In step 103, it is determined whether the card to be identified is a memory card according to the detection response signal.

[0089] The detection response signal may include a reset signal fed back by a reset signal pin, a programming voltage signal fed back by a programming voltage signal pin, and a control signal fed back by a command / reply pin.

[0090] Optionally, step 103 may include: determining whether the card to be identified is the memory card according to at least one of a reception condition of the detection response signal, a voltage of the received detection response signal, a number of received detection response signals, and information carried by the received detection response signal.

[0091] In the present disclosure, the voltage of the received detection response signal may be partially different. For example, the voltage of the detection response signal fed back by the programming voltage signal pin and the reset signal pin is a first voltage, and the voltage of the detection signal fed back by the command / reply pin is a second voltage. The first voltage can be two voltage values ​​or a voltage value range, and the second voltage can also be one voltage value or a voltage value range. Among them, the first voltage and the second voltage do not overlap. Therefore, by judging whether the voltage of the received detection response signal is the first voltage or the second voltage, it can be determined whether the card to be identified is a memory card.

[0092] Exemplarily, the first voltage may be 0.3V to 0.5V, wherein the voltage value of the detection signal corresponding to the first voltage may be 0.4V to 1.0V, and after the detection signal sent enters the card to be identified, after the voltage drop inside the card, the voltage drop of the feedback detection response signal is 0.3V to 0.5V. The second voltage may be 0.6V to 0.8V, wherein the voltage value of the detection signal corresponding to the second voltage may be 0.8V to 1.0V, and after the detection signal sent enters the card to be identified, after the voltage drop inside the card, the voltage drop of the feedback detection response signal is 0.6V to 0.8V.

[0093] In the present disclosure, the detection signal sent may also be a command signal. After receiving the command signal, the card to be identified will feed back a detection response signal carrying first information, wherein the first information can be used to determine the type of the card to be identified.

[0094] Exemplarily, the command signal may be a command to the card to be identified to feedback the ID (Identification) information of the card to be identified or other internal identity information of the card to be identified, that is, the ID information of the card to be identified or other internal identity information of the card to be identified is the information carried by the detection response signal, that is, the first information is the identity information. If the command signal is sent to the target pin, the received detection response signal is a signal carrying the identity information of the card to be identified.

[0095] Exemplarily, when a command signal is sent to the card to be identified to instruct the card to feedback ID information, the card to be identified can feedback a series of level signals representing the card ID information. For example, the card ID information is 01110011, where 0 is represented by a low level and 1 is represented by a high level. The specific type of card to be identified can be distinguished through the ID information.

[0096] The level signal is converted into a binary sequence, and the binary sequence is matched with a preset binary sequence (i.e., the first information). If the binary sequence matches (i.e., is the same as) the preset binary sequence, it indicates that the card to be identified is a memory card. If the binary sequence does not match (i.e., is different from) the preset binary sequence, it indicates that the card to be identified is not a memory card.

[0097] In one implementation of the present disclosure, when the detection signal is sent to the pin of the card to be identified in the first case, that is, when the detection signal is sent to the first target pin. The area of ​​the first target pin on the card to be identified corresponds to the area of ​​the command / reply pin on the memory card. The type of the card to be identified can be determined by the following cases.

[0098] The first category is to determine the type of the card to be identified based on the reception of the detection response signal, which may include:

[0099] When the detection response signal is not received, it is determined that the card to be identified is not a memory card. When the detection response signal is received, it is determined that the card to be identified is a memory card.

[0100] Since the area of ​​the first target pin on the card to be identified corresponds to the area of ​​the command / reply pin on the memory card, when the card to be identified is a memory card, a detection response signal will be fed back, that is, the detection response signal can be received. However, when the pin corresponding to the first target pin on the Nano-SIM card is a data transmission pin or a clock signal pin, no detection response signal will be fed back, that is, no detection response signal will be received. Therefore, it can be determined whether the card to be identified is a memory card or a Nano-SIM card based on the received detection response signal.

[0101] The second category is to determine the type of the card to be identified according to the number of received detection response signals (i.e., the number of target pins that received the detection response signals), which may include:

[0102] When the number of received detection response signals is 0, it is determined that the card to be identified is not a memory card. Alternatively, when the number of received detection response signals is 1, it is determined that the card to be identified is a memory card.

[0103] Since the area of ​​the first target pin on the card to be identified corresponds to the area of ​​the command / reply pin on the memory card, that is, when the card to be identified is a memory card, a detection response signal will be fed back, and when the pin corresponding to the first target pin on the Nano-SIM card is a data transmission pin or a clock signal pin, no detection response signal will be fed back. Therefore, it is possible to determine whether the card to be identified is a memory card or a Nano-SIM card by the number of received detection response signals.

[0104] The third category, determining the type of the card to be identified based on the number and voltage of the detection response signal, may include:

[0105] When the number of received detection response signals is 1 and the voltage of the detection response signal is the first voltage, the card to be identified is determined to be a Nano-SIM card. When the number of received detection response signals is 1 and the voltage of the detection response signal is not the first voltage, the card to be identified is determined to be a memory card.

[0106] Alternatively, when the number of received detection response signals is 1 and the voltage of the detection response signal is not the second voltage, the card to be identified is determined to be a Nano-SIM card. When the number of received detection response signals is 1 and the voltage of the detection response signal is the second voltage, the card to be identified is determined to be a memory card.

[0107] As can be seen from the above, the first voltage is the voltage of the detection response signal fed back by the programming voltage signal pin and the reset signal pin. When the detection response signal is the first voltage, it can be determined that the card to be identified is not a memory card, that is, a Nano-SIM card. The second voltage is the voltage of the detection response signal fed back by the command / reply pin. When the detection response signal is the second voltage, it can be determined that the card to be identified is a memory card. Since the area of ​​the first target pin on the card to be identified corresponds to the area of ​​the command / reply pin on the memory card, that is, when the card to be identified is a memory card, a detection response signal will be fed back and the voltage of the detection response signal is the second voltage, and when the pin corresponding to the first target pin on the Nano-SIM card is the reset pin or the programming voltage signal pin, a detection response signal will be fed back and the voltage of the detection response signal is the first voltage. Therefore, it can be determined whether the card to be identified is a memory card or a Nano-SIM card by the number and voltage of the received detection response signals. Furthermore, in the present disclosure, the card to be identified is one of a Nano-SIM card and a memory card. Therefore, when the received detection response voltage is not the first voltage or the second voltage, it can be determined that the card to be identified is a memory card or a Nano-SIM card.

[0108] The fourth category, determining the type of the card to be identified according to the voltage of the detection response signal, may include:

[0109] When the voltage of the received detection response signal is the first voltage, it is determined that the card to be identified is not a memory card. When the voltage of the received detection response signal is not the first voltage, it is determined that the card to be identified is a memory card.

[0110] Alternatively, when the voltage of the received detection response signal is the second voltage, it is determined that the card to be identified is a memory card. When the voltage of the received detection response signal is not the second voltage, it is determined that the card to be identified is not a memory card.

[0111] Since the first voltage is the voltage of the detection response signal fed back by the programming voltage signal pin and the reset signal pin, when the detection response signal is the first voltage, it can be determined that the card to be identified is a Nano-SIM card. The second voltage is the voltage of the detection response signal fed back by the command / reply pin, and when the detection response signal is the second voltage, it can be determined that the card to be identified is a memory card. Since the area of ​​the first target pin on the card to be identified corresponds to the area of ​​the command / reply pin on the memory card, that is, when the card to be identified is a memory card, a detection response signal will be fed back and the voltage of the detection response signal is the second voltage, and when the pin corresponding to the first target pin on the Nano-SIM card is the reset pin or the programming voltage signal pin, a detection response signal will be fed back and the voltage of the detection response signal is the first voltage, so it can be determined whether the card to be identified is a memory card or a Nano-SIM card by the voltage of the received detection response signal. In addition, since in the present disclosure, the card to be identified is one of a Nano-SIM card and a memory card, when the received detection response voltage is not the first voltage or the second voltage, it can also be determined that the card to be identified is a memory card or a Nano-SIM card.

[0112] The fifth category, determining the type of the card to be identified based on the information carried by the detection response signal, may include:

[0113] When the information carried by the received detection response signal is the first information, it is determined that the card to be identified is a memory card. For example, when the information carried by the received detection response signal is identity information, since the identity information is the ID information that directly distinguishes the card, the information carried by the detection response signal is the identity information, and it can be determined which type of card the card to be identified is.

[0114] Optionally, when sending a detection signal to the pin of the card to be identified is the first case, and the area of ​​the first target pin on the card to be identified does not correspond to the area of ​​the command / reply pin on the memory card, the type of the card to be identified can be determined by at least the following cases.

[0115] The first category is to determine the type of the card to be identified based on the reception of the detection response signal, which may include:

[0116] When the detection response signal is not received, it is determined that the card to be identified is a memory card. When the detection response signal is received, it is determined that the card to be identified is not a memory card.

[0117] Since the area of ​​the first target pin on the card to be identified does not correspond to the area of ​​the command / reply pin on the memory card, when the card to be identified is a memory card, no detection response signal will be fed back, that is, no detection response signal will be received. However, when the pin corresponding to the first target pin on the Nano-SIM card is a data reset pin or a programming voltage signal pin, a detection response signal will be fed back, that is, a detection response signal can be received. Therefore, it can be determined whether the card to be identified is a memory card or a Nano-SIM card based on the received detection response signal.

[0118] The second category is to determine the type of the card to be identified according to the number of received detection response signals (i.e., the number of target pins that received the detection response signals), which may include:

[0119] When the number of received detection response signals is 0, it is determined that the card to be identified is a memory card. Alternatively, when the number of received detection response signals is 1, it is determined that the card to be identified is not a memory card.

[0120] Since the area of ​​the first target pin on the card to be identified does not correspond to the area of ​​the command / reply pin on the memory card, that is, when the card to be identified is a memory card, no detection response signal will be fed back, and when the pin corresponding to the first target pin on the Nano-SIM card is a reset pin or a programming voltage signal pin, a detection response signal will be fed back. Therefore, it is possible to determine whether the card to be identified is a memory card or a Nano-SIM card by the number of received detection response signals.

[0121] In another implementation of the present disclosure, when the detection signal is sent to the pin of the card to be identified in the second case, that is, the detection signal is sent to the first target pin and the second target pin. And the area of ​​the first target pin on the card to be identified corresponds to the area of ​​the command / reply pin on the memory card. The type of the card to be identified can be determined by at least the following cases.

[0122] The first category is to determine the type of the card to be identified based on the reception of the detection response signal, which may include:

[0123] When a detection response signal is received from both the first target pin and the second target pin or no detection response signal is received, it is determined that the card to be identified is not a memory card. When a detection response signal is received from the first target pin and no detection response signal is received from the second target pin, it is determined that the card to be identified is a memory card.

[0124] Since the area of ​​the first target pin on the card to be identified corresponds to the area of ​​the command / reply pin on the memory card, that is, when the card to be identified is a memory card, the first target pin will feedback a detection response signal, and the second target pin can correspond to the first data transmission pin, the second data transmission pin, etc., that is, the second target pin will not feedback a detection response signal. When the pins corresponding to the first target pin and the second target pin on the Nano-SIM card are the data transmission pin and the clock signal pin, no detection response signal will be fed back, and when the pins corresponding to the first target pin and the second target pin on the Nano-SIM card are the reset pin and the programming voltage signal pin, both will feedback a detection response signal. Therefore, it can be determined whether the card to be identified is a memory card or a Nano-SIM card by the received detection response signal.

[0125] The second category, determining the type of the card to be identified based on the number of detection response signals, may include:

[0126] When the number of received detection response signals is 0 or 2, it is determined that the card to be identified is not a memory card. When the number of received detection response signals is 1, it is determined that the card to be identified is a memory card. Since the area of ​​the first target pin on the card to be identified corresponds to the area of ​​the command / reply pin on the memory card, and the second target pin can correspond to the first data transmission pin, the second data transmission pin, etc., that is, when the card to be identified is a memory card, since only the command / reply pin in the memory card will feedback the detection response signal, only 1 detection response signal will be fed back. When the first target pin and the second target pin correspond to the data transmission pin and the clock signal pin on the Nano-SIM card, no detection response signal will be fed back, and when the first target pin and the second target pin correspond to the reset pin and the programming voltage signal pin on the Nano-SIM card, both will feedback the detection response signal, so it can be determined whether the card to be identified is a memory card or a Nano-SIM card by the number of received detection response signals.

[0127] The third category, determining the type of the card to be identified based on the number and voltage of the detection response signal, may include:

[0128] When the number of received detection response signals is 1 and the voltage of the detection response signal is the first voltage, it is determined that the card to be identified is not a memory card. When the number of received detection response signals is 1 and the voltage of the detection response signal is not the first voltage, it is determined that the card to be identified is a memory card.

[0129] Alternatively, when the number of received detection response signals is 1 and the voltage of the detection response signal is the second voltage, the card to be identified is determined to be a memory card. When the number of received detection response signals is 1 and the voltage of the detection response signal is not the second voltage, the card to be identified is determined not to be a memory card.

[0130] Since the first voltage is the voltage of the detection response signal fed back by the programming voltage signal pin and the reset signal pin, when the detection response signal is the first voltage, it can be directly determined that the card to be identified is not a memory card, that is, a Nano-SIM card. The second voltage is the voltage of the detection response signal fed back by the command / reply pin, and when the detection response signal is the second voltage, it can be directly determined that the card to be identified is a memory card. In the present disclosure, the card to be identified is one of a Nano-SIM card and a memory card, therefore, when the received detection response voltage is not the first voltage or the second voltage, it can also be determined that the card to be identified is a memory card or a Nano-SIM card.

[0131] The fourth category, determining the type of the card to be identified based on the information carried by the detection response signal, may include:

[0132] When the information carried by the detection response signal received from the first target pin is the same as the first information, it is determined that the card to be identified is a memory card. When the information carried by the detection response signal received from the first target pin is different from the first information, it is determined that the card to be identified is not a memory card. When the information carried by the received detection response signal is identity information, that is, when the first information is identity information, since the identity information is the ID information that directly distinguishes the card, the information carried by the detection response signal is the identity information, and it can be determined which type of card the card to be identified is. For example, when the card to be identified is a memory card, the information carried by the detection response signal is the identity information of the memory card, and when the card to be identified is a Nano-SIM card, the information carried by the detection response signal is the identity information of the Nano-SIM card. Different cards have different corresponding identity information, so the above two types of identity information are different.

[0133] In another implementation of the present disclosure, when sending a detection signal to the pin of the card to be identified is the third case, that is, sending a detection signal to the first target pin, the second target pin and the third target pin.

[0134] The above situation may include: the regions of the first target pin, the second target pin and the third target pin on the card to be identified correspond to three different regions of the clock signal pin, the first data transmission pin and the second data transmission pin on the memory card. In this case, the type of the card to be identified can be determined by the following situations.

[0135] The first category is to determine the type of the card to be identified based on the reception of the detection response signal, which may include:

[0136] When the detection response signal is not received, it is determined that the card to be identified is not a memory card. When the detection response signal is received, it is determined that the card to be identified is a memory card.

[0137] Since the areas of the first target pin, the second target pin and the third target pin on the card to be identified correspond to the three different areas of the clock signal pin, the first data transmission pin and the second data transmission pin on the memory card, when the card to be identified is a memory card, no detection response signal will be fed back, that is, the detection response signal can be received. When the pins corresponding to the first target pin, the second target pin and the third target pin on the Nano-SIM card include at least one of the reset pin and the programming voltage signal pin, the detection response signal will be fed back, that is, the detection response signal will be received. Therefore, it can be determined whether the card to be identified is a memory card or a Nano-SIM card by the received detection response signal.

[0138] The second category, determining the type of the card to be identified based on the number of detection response signals, may include:

[0139] When the number of received detection response signals is 0, it is determined that the card to be identified is a memory card. When the number of received detection response signals is 1 or 2, it is determined that the card to be identified is a Nano-SIM card. Since the areas of the first target pin, the second target pin and the third target pin on the card to be identified correspond to the three different areas of the clock signal pin, the first data transmission pin and the second data transmission pin on the memory card, that is, when the card to be identified is a memory card, no detection response signal will be fed back, that is, no detection response signal will be received. When the pins corresponding to the first target pin, the second target pin and the third target pin on the Nano-SIM card include at least one of the reset pin and the programming voltage signal pin, a detection response signal will be fed back, that is, a detection response signal will be received, so it can be determined whether the card to be identified is a memory card or a Nano-SIM card by the number of received detection response signals.

[0140] The third category, determining the type of the card to be identified based on the number and voltage of the detection response signal, may include:

[0141] When the number of received detection response signals is 1 or 2 and the voltage of the detection response signal is the first voltage, it is determined that the card to be identified is not a memory card. When the number of received detection response signals is and the voltage of the detection response signal is not the first voltage, it is determined that the card to be identified is a memory card.

[0142] Since the first voltage is the voltage of the detection response signal fed back by the programming voltage signal pin and the reset signal pin, when the detection response signal is the first voltage, it can be directly determined that the card to be identified is not a memory card, that is, a Nano-SIM card.

[0143] The fourth category, determining the type of the card to be identified according to the voltage of the detection response signal, may include:

[0144] When the voltage of the received detection response signal is the first voltage, it is determined that the card to be identified is not a memory card. When the voltage of the received detection response signal is not the first voltage, it is determined that the card to be identified is a memory card. Since the first voltage is the voltage of the detection response signal fed back by the programming voltage signal pin and the reset signal pin, when the detection response signal is the first voltage, it can be directly determined that the card to be identified is not a memory card, that is, a Nano-SIM card.

[0145] The fifth category, determining the type of the card to be identified based on the information carried by the detection response signal, may include:

[0146] When the information carried by the received detection response signal is different from the first information, it is determined that the card to be identified is not a memory card. When the information carried by the received detection response signal is identity information, that is, the first information is identity information, since the identity information is the ID information that directly distinguishes the card, the information carried by the detection response signal is the identity information, and it can be determined what type of card the card to be identified is. For example, when the card to be identified is a memory card, the information carried by the detection response signal is the identity information of the memory card, and the identity information is the first information. When the card to be identified is a Nano-SIM card, the information carried by the detection response signal is the identity information of the Nano-SIM card, which is information different from the first information, that is, the information carried by the detection response signal is different from the first information.

[0147] The above situation may also include: the area of ​​one of the first target pin, the second target pin and the third target pin on the card to be identified corresponds to the area of ​​the command / reply pin on the memory card. In this case, the type of the card to be identified can be determined by the following situations.

[0148] The first category, determining the type of the card to be identified based on the number of detection response signals, may include:

[0149] When the number of received detection response signals is 2, it is determined that the card to be identified is a Nano-SIM card. Since only the command / reply pin of the pins in the memory card will feedback the detection response signal, only one detection response signal is fed back. Therefore, when the number of detection response signals is 2, it can be directly determined that the card to be identified is a Nano-SIM card. For example, when the card to be identified is a Nano-SIM card, the first target pin, the second target pin, and the third target pin can correspond to the reset pin, the programming voltage pin, and the data transmission pin, respectively.

[0150] The second category is to determine the type of card to be identified based on the number and voltage of the detection response signal, which may include:

[0151] When the number of received detection response signals is 1 and the voltage of the detection response signal is the first voltage, it is determined that the card to be identified is not a memory card. When the number of received detection response signals is 1 and the voltage of the detection response signal is not the first voltage, it is determined that the card to be identified is a memory card. When the number of received detection response signals is 2 and the voltage of the detection response signal is the first voltage, it is determined that the card to be identified is not a memory card.

[0152] Alternatively, when the number of received detection response signals is 1 and the voltage of the detection response signal is the second voltage, the card to be identified is determined to be a memory card. When the number of received detection response signals is 1 and the voltage of the detection response signal is not the second voltage, the card to be identified is determined not to be a memory card.

[0153] Since the first voltage is the voltage of the detection response signal fed back by the programming voltage signal pin and the reset signal pin, when the detection response signal is the first voltage, it can be directly determined that the card to be identified is not a memory card, that is, a Nano-SIM card. The second voltage is the voltage of the detection response signal fed back by the command / reply pin, and when the detection response signal is the second voltage, it can be directly determined that the card to be identified is a memory card. In the present disclosure, the card to be identified is one of a Nano-SIM card and a memory card, therefore, when the received detection response voltage is not the first voltage or the second voltage, it can also be determined that the card to be identified is a memory card or a Nano-SIM card.

[0154] The third category, determining the type of the card to be identified based on the voltage of the detection response signal, may include:

[0155] When the voltage of the received detection response signal is the first voltage, it is determined that the card to be identified is not a memory card. When the voltage of the received detection response signal is not the first voltage, it is determined that the card to be identified is a memory card.

[0156] Alternatively, when the voltage of the received detection response signal is the second voltage, it is determined that the card to be identified is a memory card. When the voltage of the received detection response signal is not the second voltage, it is determined that the card to be identified is a memory card. Since the first voltage is the voltage of the detection response signal fed back by the programming voltage signal pin and the reset signal pin, when the detection response signal is the first voltage, it can be directly determined that the card to be identified is not a memory card, that is, a Nano-SIM card. The second voltage is the voltage of the detection response signal fed back by the command / reply pin, and when the detection response signal is the second voltage, it can be directly determined that the card to be identified is a memory card. In the present disclosure, the card to be identified is one of a Nano-SIM card and a memory card. Therefore, when the received detection response voltage is not the first voltage or the second voltage, it can also be determined that the card to be identified is a memory card or a Nano-SIM card.

[0157] The fourth category, determining the type of the card to be identified based on the information carried by the detection response signal, may include:

[0158] When the information carried by the received detection response signal is the first information, it is determined that the card to be identified is a memory card. When the information carried by the received detection response signal is different from the first information, it is determined that the card to be identified is not a memory card. When the information carried by the received detection response signal is identity information, that is, when the first information is identity information, since the identity information is the ID information that directly distinguishes the card, the information carried by the detection response signal is the identity information, and it can be determined which type of card the card to be identified is. For example, when the card to be identified is a memory card, the information carried by the detection response signal is the identity information of the memory card, and the identity information is the first information. When the card to be identified is a Nano-SIM card, the information carried by the detection response signal is the identity information of the Nano-SIM card, which is information different from the first information, that is, the information carried by the detection response signal is different from the first information.

[0159] In another implementation of the present disclosure, when sending a detection signal to the pin of the card to be identified is the fourth case, that is, sending a detection signal to the first target pin, the second target pin, the third target pin and the fourth target pin, the type of the card to be identified can be determined by the following cases.

[0160] The first category, determining the type of the card to be identified based on the number of detection response signals, may include:

[0161] When the number of detection response signals is 2, it is determined that the card to be identified is not a memory card. When the number of detection response signals is 1, it is determined that the card to be identified is a memory card. Since only the command / reply pin among the four pins of the memory card can feedback the detection response signal, and the reset signal pin and the programming voltage signal pin among the four pins of the Nano-SIM card can feedback the detection response signal, the type of the card to be identified can be determined according to the number of feedbacks.

[0162] The second category is to determine the type of card to be identified based on the number and voltage of the detection response signal, which may include:

[0163] When the number of received detection response signals is 1 and the voltage of the detection response signal is the second voltage, it is determined that the card to be identified is a memory card. When the number of received detection response signals is 2 and the voltage of the detection response signal is the first voltage, it is determined that the card to be identified is not a memory card. Since the first voltage is the voltage of the detection response signal fed back by the programming voltage signal pin and the reset signal pin, when the detection response signal is the first voltage, it can be directly determined that the card to be identified is not a memory card, that is, a Nano-SIM card. The second voltage is the voltage of the detection response signal fed back by the command / reply pin, and when the detection response signal is the second voltage, it can be directly determined that the card to be identified is a memory card.

[0164] The third category, determining the type of the card to be identified based on the voltage of the detection response signal, may include:

[0165] When the voltage of the received detection response signal is the first voltage, it is determined that the card to be identified is not a memory card. When the voltage of the received detection response signal is the second voltage, it is determined that the card to be identified is a memory card. Since the first voltage is the voltage of the detection response signal fed back by the programming voltage signal pin and the reset signal pin, when the detection response signal is the first voltage, it can be directly determined that the card to be identified is not a memory card, that is, a Nano-SIM card. The second voltage is the voltage of the detection response signal fed back by the command / reply pin, and when the detection response signal is the second voltage, it can be directly determined that the card to be identified is a memory card.

[0166] The fourth category, determining the type of the card to be identified based on the information carried by the detection response signal, may include:

[0167] When the information carried by the received detection response signal is the first information, it is determined that the card to be identified is a memory card. When the information carried by the received detection response signal is different from the first information, it is determined that the card to be identified is not a memory card. When the information carried by the received detection response signal is identity information, that is, when the first information is identity information, since the identity information is the ID information that directly distinguishes the card, the information carried by the detection response signal is the identity information, and it can be determined which type of card the card to be identified is. For example, when the card to be identified is a memory card, the information carried by the detection response signal is the identity information of the memory card, and the identity information is the first information. When the card to be identified is a Nano-SIM card, the information carried by the detection response signal is the identity information of the Nano-SIM card, which is information different from the first information, that is, the information carried by the detection response signal is different from the first information.

[0168] In the disclosed embodiment, due to the minor change in the position of the pins on the memory card (such as Figure 4 , 5 The memory card shown in ) has a high consistency with the Nano-SIM card, so it is easier to adapt to the Nano-SIM card holder and the cost is lower. When distinguishing the above two memory cards and the Nano-SIM card, the identification method may include:

[0169] In step 101, a detection signal is sent to a target pin of a card to be identified.

[0170] The card to be identified is a Nano-SIM card or the memory card mentioned above.

[0171] In step 101, the target pin includes at least one of a first target pin and a second target pin. That is, sending a detection signal to the target pin of the card to be identified may include: sending a detection signal to at least one of the first target pin and the second target pin of the card to be identified.

[0172] In the present disclosure, sending a detection signal to a target pin of a card to be identified may include the following two situations.

[0173] The first one is to send the detection signal only to the first target pin, that is, the target pin is the first target pin.

[0174] The second method is to send a detection signal to both the first target pin and the second target pin, that is, the target pins include the first target pin and the second target pin.

[0175] For the related description of the detection signal, please refer to the aforementioned step 101, and the detailed description is omitted here.

[0176] In step 102, a detection response signal fed back by the card to be identified is received.

[0177] Since the card to be identified in the present disclosure is one of a memory card and a Nano-SIM card, the first target pin and the second target pin may include a reset signal pin, a programming voltage signal pin, a command / reply pin, and a second data transmission pin. When a detection signal is sent to the reset signal pin, the programming voltage signal pin, and the command / reply pin, the three pins will all feedback different detection response signals, for example, the voltage values ​​of the detection response signals fed back by the reset signal pin, the programming voltage signal pin, and the command / reply pin are different. The feedback detection response signal will be transmitted to the terminal through the card holder and received by the control unit in the terminal; at the same time, the second data transmission pin is a transmission channel, and the pin will not feedback the detection response signal after receiving the detection signal, thereby providing the possibility of identifying the card to be identified.

[0178] In step 103, it is determined whether the card to be identified is a memory card according to the detection response signal.

[0179] The detection response signal may include a reset signal fed back by a reset signal pin, a programming voltage signal fed back by a programming voltage signal pin, and a control signal fed back by a command / reply pin.

[0180] Optionally, step 103 may include: determining whether the card to be identified is the memory card according to at least one of a voltage of a received detection response signal, a number of detection response signals, and information carried by the detection response signal.

[0181] In one implementation of the present disclosure, when the detection signal is sent to the pin of the card to be identified in the first case, that is, when the detection signal is sent to the first target pin. The area of ​​the first target pin on the card to be identified corresponds to the area of ​​the command / reply pin on the memory card. The type of the card to be identified can be determined by the following cases.

[0182] The first category, determining the type of the card to be identified based on the number and voltage of the detection response signal, may include:

[0183] When the number of received detection response signals is 1 and the voltage of the detection response signal is the first voltage, the card to be identified is determined to be a Nano-SIM card. When the number of received detection response signals is 1 and the voltage of the detection response signal is not the first voltage, the card to be identified is determined to be a memory card.

[0184] Alternatively, when the number of received detection response signals is 1 and the voltage of the detection response signal is the second voltage, the card to be identified is determined to be a memory card. When the number of received detection response signals is 1 and the voltage of the detection response signal is not the second voltage, the card to be identified is determined not to be a memory card.

[0185] Since the first voltage is the voltage of the detection response signal fed back by the programming voltage signal pin and the reset signal pin, when the detection response signal is the first voltage, it can be directly determined that the card to be identified is not a memory card, that is, a Nano-SIM card. The second voltage is the voltage of the detection response signal fed back by the command / reply pin, and when the detection response signal is the second voltage, it can be directly determined that the card to be identified is a memory card. In the present disclosure, the card to be identified is one of a Nano-SIM card and a memory card, therefore, when the received detection response voltage is not the first voltage or the second voltage, it can also be determined that the card to be identified is a memory card or a Nano-SIM card.

[0186] The second category is to determine the type of the card to be identified based on the voltage of the detection response signal, which may include:

[0187] When the voltage of the received detection response signal is the first voltage, it is determined that the card to be identified is not a memory card. When the voltage of the received detection response signal is not the first voltage, it is determined that the card to be identified is a memory card.

[0188] Alternatively, when the voltage of the received detection response signal is the second voltage, it is determined that the card to be identified is a memory card. When the voltage of the received detection response signal is not the second voltage, it is determined that the card to be identified is not a memory card.

[0189] Since the first voltage is the voltage of the detection response signal fed back by the programming voltage signal pin and the reset signal pin, when the detection response signal is the first voltage, it can be directly determined that the card to be identified is a Nano-SIM card. The second voltage is the voltage of the detection response signal fed back by the command / reply pin, and when the detection response signal is the second voltage, it can be directly determined that the card to be identified is a memory card. In the present disclosure, the card to be identified is one of a Nano-SIM card and a memory card. Therefore, when the received detection response voltage is not the first voltage or the second voltage, it can also be determined that the card to be identified is a memory card or a Nano-SIM card.

[0190] The third category is to determine the type of the card to be identified based on the information carried by the detection response signal, which may include:

[0191] When the information carried by the received detection response signal is the first information, it is determined that the card to be identified is a memory card. When the information carried by the received detection response signal is different from the first information, it is determined that the card to be identified is not a memory card. When the information carried by the received detection response signal is identity information, that is, when the first information is identity information, since the identity information is the ID information that directly distinguishes the card, the information carried by the detection response signal is the identity information, and it can be determined which type of card the card to be identified is. For example, when the card to be identified is a memory card, the information carried by the detection response signal is the identity information of the memory card, and the identity information is the first information. When the card to be identified is a Nano-SIM card, the information carried by the detection response signal is the identity information of the Nano-SIM card, which is information different from the first information, that is, the information carried by the detection response signal is different from the first information.

[0192] In another implementation of the present disclosure, when the detection signal is sent to the pin of the card to be identified in the first case, that is, when the detection signal is sent to the first target pin. The area of ​​the first target pin on the card to be identified corresponds to the area of ​​the second data transmission pin on the memory card. The type of the card to be identified can be determined by the following cases.

[0193] The first category, determining the type of the card to be identified based on the number of detection response signals, may include:

[0194] When the number of received detection response signals is 1, it is determined that the card to be identified is a Nano-SIM card. When the number of received detection response signals is 0, it is determined that the card to be identified is a memory card. Since the area of ​​the first target pin on the card to be identified corresponds to the area of ​​the second data transmission pin on the memory card, that is, when the card to be identified is a memory card, no detection response signal will be fed back. Therefore, when the number of detection response signals is 0, it can be directly determined that the card to be identified is a memory card, and when the card to be identified is a Nano-SIM card, a detection response signal will be fed back, so that it can be determined that the card to be identified is a Nano-SIM card.

[0195] The second category is to determine the type of card to be identified based on the number and voltage of the detection response signal, which may include:

[0196] When the number of received detection response signals is 1 and the voltage of the detection response signal is the first voltage, it is determined that the card to be identified is a Nano-SIM card. Since the first voltage is the voltage of the detection response signal fed back by the programming voltage signal pin and the reset signal pin, when the detection response signal is the first voltage, it can be directly determined that the card to be identified is not a memory card, that is, a Nano-SIM card.

[0197] The third category, determining the type of the card to be identified based on the voltage of the detection response signal, may include:

[0198] When the voltage of the received detection response signal is the first voltage, it is determined that the card to be identified is not a memory card. Since the first voltage is the voltage of the detection response signal fed back by the programming voltage signal pin and the reset signal pin, when the detection response signal is the first voltage, it can be directly determined that the card to be identified is a Nano-SIM card.

[0199] The fourth category, determining the type of the card to be identified based on the information carried by the detection response signal, may include:

[0200] When the information carried by the received detection response signal is the first information, it is determined that the card to be identified is a memory card. When the information carried by the received detection response signal is different from the first information, it is determined that the card to be identified is not a memory card. When the information carried by the received detection response signal is identity information, that is, when the first information is identity information, since the identity information is the ID information that directly distinguishes the card, the information carried by the detection response signal is the identity information, and it can be determined which type of card the card to be identified is. For example, when the card to be identified is a memory card, the information carried by the detection response signal is the identity information of the memory card, and the identity information is the first information. When the card to be identified is a Nano-SIM card, the information carried by the detection response signal is the identity information of the Nano-SIM card, which is information different from the first information, that is, the information carried by the detection response signal is different from the first information.

[0201] In another implementation of the present disclosure, when sending a detection signal to the pin of the card to be identified is the second case, that is, sending a detection signal to the first target pin and the second target pin, the type of the card to be identified can be determined by the following cases.

[0202] The first category, determining the type of the card to be identified based on the number of detection response signals, may include:

[0203] When the number of received detection response signals is 1, it is determined that the card to be identified is a memory card. When the number of received detection response signals is 2, it is determined that the card to be identified is not a memory card. When the card to be identified is a memory card, there is a command / reply pin that feeds back a detection response signal, and when the card to be identified is a Nano-SIM card, both pins on it feed back a detection response signal. Therefore, when the number of detection response signals is 1, it can be determined that the card to be identified is a memory card, and when the number of detection response signals is 2, it can be determined that the card to be identified is a Nano-SIM card.

[0204] The second category is to determine the type of card to be identified based on the number and voltage of the detection response signal, which may include:

[0205] When the number of received detection response signals is 1 and the voltage of the detection response signal is the second voltage, it is determined that the card to be identified is a memory card. When the number of received detection response signals is 2 and the voltage of the detection response signal is the first voltage, it is determined that the card to be identified is not a memory card. Since the first voltage is the voltage of the detection response signal fed back by the programming voltage signal pin and the reset signal pin, when the detection response signal is the first voltage, it can be directly determined that the card to be identified is not a memory card, that is, a Nano-SIM card. The second voltage is the voltage of the detection response signal fed back by the command / reply pin, and when the detection response signal is the second voltage, it can be directly determined that the card to be identified is a memory card.

[0208] Alternatively, when the voltage of the received detection response signal is the second voltage, it is determined that the card to be identified is a memory card. When the voltage of the received detection response signal is not the second voltage, it is determined that the card to be identified is not a memory card.

[0209] Since the first voltage is the voltage of the detection response signal fed back by the programming voltage signal pin and the reset signal pin, when the detection response signal is the first voltage, it can be directly determined that the card to be identified is a Nano-SIM card. The second voltage is the voltage of the detection response signal fed back by the command / reply pin, and when the detection response signal is the second voltage, it can be directly determined that the card to be identified is a memory card. In the present disclosure, the card to be identified is one of a Nano-SIM card and a memory card. Therefore, when the received detection response voltage is not the first voltage or the second voltage, it can also be determined that the card to be identified is a memory card or a Nano-SIM card.

[0210] The fourth category, determining the type of the card to be identified based on the information carried by the detection response signal, may include:

[0211] When the information carried by the received detection response signal is the first information, it is determined that the card to be identified is a memory card. When the information carried by the received detection response signal is different from the first information, it is determined that the card to be identified is not a memory card. When the information carried by the received detection response signal is identity information, that is, when the first information is identity information, since the identity information is the ID information that directly distinguishes the card, the information carried by the detection response signal is the identity information, and it can be determined which type of card the card to be identified is. For example, when the card to be identified is a memory card, the information carried by the detection response signal is the identity information of the memory card, and the identity information is the first information. When the card to be identified is a Nano-SIM card, the information carried by the detection response signal is the identity information of the Nano-SIM card, which is information different from the first information, that is, the information carried by the detection response signal is different from the first information.
