[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0022] Near Field Communication NFC, also known as Near Field Wireless Communication, is a high-frequency wireless communication technology used to achieve contactless data transmission between devices. With the continuous improvement of NFC technology, the application of NFC technology in electronic devices has become popular. In related technologies, a security chip is set in an electronic device to store the data of an NFC simulated card, so that NFC can be used to simulate bus cards, access cards, car keys, etc. In this way, by simulating access cards, bus cards, car keys, etc. through NFC, functions such as swiping a bus card, swiping a door card, or unlocking a car key can be realized through the electronic device, which helps to facilitate the user's life. The following is combined with Figure 1 The application scenarios of NFC simulated cards are described.

[0023] Figure 1 This is an application scenario diagram of near field communication interaction based on NFC card provided in an embodiment of the present application, such as Figure 1As shown, it includes an electronic device 110 and a card reader 120, and the electronic device 110 may be provided with an NFC chip 111 and a secure chip (secure element, SE) 112. Among them, the secure chip 112 may be, for example, an embedded security chip (embedded security element, ESE), the security chip 112 may be packaged together with the NFC chip, and the security chip 112 may also be integrated on the printed circuit board (printed circuit board, PBC) of the electronic device 110. In the case where the security chip 112 is integrated on the PBC of the electronic device 110, the security chip 112 may be independent of other software and hardware of the electronic device 110. It should be understood that the NFC chip 111 and the security chip 112 are both located in the hardware layer of the electronic device 110.

[0024] In some embodiments, the electronic device 110 is a removable electronic device with NFC communication function. As some specific examples, the electronic device 110 is a mobile phone, a tablet computer, a PDA, a mobile internet device (MID), a wearable device, etc.

[0025] An NFC card swiping system can be set in the card reader device 120, so that the card reader device 120 can realize near-field communication interaction with the electronic device 110 with an NFC simulated card based on the NFC card swiping system. The NFC card swiping system set in the card reader device 120 can be a public transportation system, a payment system, an access control system, etc. This application does not limit the specific NFC card swiping system in the card reader device 120.

[0026] However, the current NFC function can only keep one simulated card in an activated state by default. For example, when receiving the proximity signal of the NFC reader, the contactless parameters of the activated NFC simulated card are used by default to interact with the NFC reader. For example, the currently activated NFC simulated card is a simulated bus card. When the user needs to use the access card to unlock the access control, he needs to manually switch to activate the NFC simulated access card. This operation process is cumbersome and the user's physical examination is poor.

[0027] In order to solve the above problems, an embodiment of the present application provides an activation method for an NFC simulation card, which is applied to an electronic device, and the electronic device includes: multiple NFC simulation cards; a security chip for storing contactless parameters of multiple NFC simulation cards; the method includes: determining a target NFC simulation card, the target NFC simulation card includes at least two NFC simulation cards among the multiple NFC simulation cards; using the security chip to perform composite processing on the contactless parameters of the target NFC simulation card to obtain composite contactless parameters; according to the composite contactless parameters, activating the target NFC simulation card. This solution performs composite processing on the contactless parameters of the target NFC simulation card, and then activates the target NFC simulation card (i.e., multiple NFC simulation cards) simultaneously according to the composite parameters, which helps to meet the user's changing application needs and improve the user experience.

[0028] It should be noted that the electronic device in the embodiment of the present application may include multiple NFC simulation cards and a security chip. The multiple NFC simulation cards may be, for example, at least two NFC simulation cards, and the multiple NFC simulation cards may include, for example, an NFC simulation bus card, an NFC simulation access card, an NFC simulation car key card, etc., and the present application does not impose any specific restrictions on this. The security chip may be used to store the contactless parameters of multiple NFC simulation cards and to manage multiple NFC simulation cards. The security chip may, for example, Figure 1 The security chip 122 in.

[0029] Combined with the following Figure 2 The activation method of the NFC simulation card in the embodiment of the present application is described in detail. Figure 2 As shown, the NFC simulated card activation method 200 can be used for an electronic device. It should be understood that the electronic device can be any type of electronic device mentioned above, such as Figure 1 The electronic device 110 in the NFC simulation card activation method 200 may include steps: S210-S230.

[0030] In step S210, a target NFC simulation card is determined, wherein the target NFC simulation card includes at least two NFC simulation cards among a plurality of NFC simulation cards in the electronic device.

[0031] It is understandable that the target NFC simulation card can be an NFC simulation card that the user wants to activate, and the target NFC simulation card includes at least one NFC simulation card in a deactivated state. In some embodiments, the target NFC simulation card can refer to any at least two NFC simulation cards among multiple NFC simulation cards in the electronic device.

[0032] In some embodiments, the electronic device may further include a security chip application, which is located at the application layer of the electronic device. The security chip application may be, for example, a wallet application. The security chip application may be used to manage multiple NFC simulated cards. For example, a user may trigger an activation instruction for one or more NFC simulated cards through the UI interface of the security chip application.

[0033] In step S220, the contactless parameters of the target NFC simulation card are composited using the security chip to obtain composite contactless parameters.

[0034] In some embodiments, a user may use a security chip application to send a first activation instruction to the security chip, where the first activation instruction may include application identifiers (AIDs) of some or all NFC simulation cards in the target NFC simulation card; the security chip may receive the first activation instruction sent by the security chip application, and then, according to the first activation instruction, use the security chip to composite the contactless parameters of the target NFC simulation card to obtain composite contactless parameters.

[0035] It should be noted that the application identifier of the NFC simulated card may refer to the identity identifier in the security chip application that the security chip assigns to the NFC simulated card after the NFC simulates a physical card (such as a bus card, access card, etc.).

[0036] It can be understood that when the security chip receives the first activation instruction, it can obtain the application identifier of the target NFC simulation card. Using the application identifier of the target NFC simulation card, it can obtain the contactless parameters of the target NFC simulation card. Then, the security chip can be used to composite the contactless parameters of the target NFC simulation card to obtain composite contactless parameters.

[0037] In some embodiments, the first activation instruction may refer to an activation instruction of a target NFC simulation card triggered by a user through a UI interface of a security chip application. As an example, the UI interface of a security chip application may be used to display multiple NFC simulation cards in an electronic device, and may have check boxes for multiple NFC simulation cards. A user may select a target NFC simulation card through the check box, and then trigger an activation function button in the security application to generate an activation instruction (i.e., the first activation instruction) for the target NFC simulation card.

[0038] In some embodiments, the contactless parameters of the target NFC simulation card may include: unique identifier (UID) of the NFC simulation card, select acknowledgement (SAK), answer to select (ATS), answer to request (ATQ), etc. Among them, the request response ATQ may be, for example, the request response ATQA of a Class A card.

[0039] In some embodiments, the contactless parameters of the target NFC simulation card can be composited using a security chip according to the application protocol of the target NFC simulation card to obtain composite contactless parameters. It should be understood that the application protocol of the NFC simulation card specifies the necessary contactless parameters for near-field communication between the NFC simulation card and the card reader device. As an example, according to the application protocol of the NFC simulation transportation card, the necessary contactless parameters of the NFC simulation transportation card can be determined to be the selection response ATS and the selection confirmation SAK. As another example, according to the application protocol of the NFC simulation access control card, the necessary contactless parameters of the NFC simulation access control card can be determined to be the unique identifier UID, the request response ATQ and the selection confirmation SAK. It can be understood that the above-mentioned application protocol may refer to relevant NFC card communication protocols such as ISO14443 and ISO7816.

[0040] In some embodiments, the target NFC simulation card may include a transportation NFC simulation card and an access control NFC simulation card, and the composite contactless parameters of the transportation NFC simulation card and the access control NFC simulation card may include a unique identifier and request response of the access control NFC simulation card, a selection response of the transportation NFC simulation card, and a composite selection confirmation of the transportation NFC simulation card and the access control NFC simulation card.

[0041] As an example, if the selection confirmation SAK of the traffic NFC simulation card is 0x20 (hexadecimal number), and the selection confirmation SAK of the access control NFC simulation card is 0x08 / 0x18 (hexadecimal number), then the selection confirmation SAK of the traffic NFC simulation card and the access control NFC simulation card can be 0x28 / 0x38 (hexadecimal number). That is, 0x28 = 0x08 + 0x20, 0x38 = 0x18 + 0x20. It should be understood that in the application protocol of the NFC simulation card, 0x28 can cover 0x20 and 0x08, and 0x38 can cover 0x20 and 0x18.

[0042] In step S230, the target NFC simulated card is activated according to the composite contactless parameter.

[0043] In some embodiments, after the composite contactless parameters of the target NFC simulation card are generated by using the security chip, the NFC simulation card contactless parameters of the NFC chip can be modified according to the service contactless parameters, so that the target NFC simulation card can be activated.

[0044] In some embodiments, the composite contactless parameters of the target NFC simulation card can be sent to the NFC chip using a security chip, and then the NFC simulation card contactless parameters in the NFC chip are modified according to the composite contactless parameters. In this way, the composite contactless parameters can cover multiple NFC simulation cards in the target NFC simulation card, thereby activating the multiple NFC simulation cards.

[0045] According to the above description, compared with the traditional solution that can only activate one NFC simulated card, this solution composites the contactless parameters of the target NFC simulated card, and then activates the target NFC simulated cards (i.e. multiple NFC simulated cards) simultaneously according to the composite parameters, which helps to meet the user's changing application needs and improve the user experience.

[0046] In some embodiments, the electronic device may further include a security process service layer, and the security process service layer includes a security program process. The security process service layer may be located between the security chip application and the security chip; before the security chip receives the first activation instruction using the security chip, the first activation instruction may be sent to the security process service layer using the security chip application; then, the first activation instruction is encrypted in the security process service layer. In some embodiments, the security process service layer may be a trusted execution environment (TEE) environment or a rich execution environment (REE).

[0047] In some embodiments, the key in the security chip can be used to verify the first activation instruction encrypted by the security process service layer; if the key verification is successful, the security chip can be used to composite the contactless parameters of the target NFC simulation card according to the verified first activation instruction to obtain composite contactless parameters. The encryption of the security process service layer can ensure the security of the data.

[0048] In some embodiments, the electronic device may further include an application interface layer, which may refer to an open mobile application interface (OMA) layer. The application interface layer may be located between the security chip application and the security process service layer, and is mainly used to connect the security chip application and the security process service layer, so as to realize data transmission between the security chip application and the security process service layer. In some embodiments, before the security process service layer encrypts the first activation instruction, the legitimacy of the first activation instruction may be verified at the application interface layer; if the first activation instruction is legal, the first activation instruction may be transmitted to the security process service layer through the application interface layer; then, the first activation instruction is encrypted using the security process service layer. The legitimacy of the first activation instruction may refer to the correctness and / or validity of the application identifier of the NFC simulated card carried by the first activation instruction.

[0049] In some embodiments, the target NFC simulation card includes a first NFC simulation card and a second NFC simulation card. If the first NFC simulation card and the second NFC simulation card are both in a deactivated state, the first activation instruction includes the application identifiers of all NFC simulation cards in the target NFC simulation card, that is, the first activation instruction includes the application identifier of the first NFC simulation card and the application identifier of the second NFC simulation card; if the first NFC simulation card is in an activated state and the second NFC simulation card is in a deactivated state, the first activation instruction includes the application identifiers of some NFC simulation cards in the target NFC simulation card, that is, the first activation instruction includes the application identifier of the second NFC simulation card, and the first activation instruction does not include the application identifier of the first NFC simulation card. It should be understood that the first NFC simulation card and the second NFC simulation card may refer to any two NFC simulation cards in the target NFC simulation card.

[0050] In some embodiments, before the contactless parameters of the target NFC simulation card are composited using the security chip, it can be determined whether there is an activation conflict among the multiple NFC simulation cards in the target NFC simulation card; if there is no activation conflict among the multiple NFC simulation cards in the target NFC simulation card, the contactless parameters of the target NFC simulation card are composited using the security chip to obtain composite contactless parameters. Of course, if there is an activation conflict among the multiple NFC simulation cards in the target NFC simulation card, the contactless parameters of the target NFC simulation card cannot be composited using the security chip.

[0051] In some embodiments, it can be detected whether there is a conflict in the contactless parameters of multiple NFC simulation cards in the target NFC simulation card; if there is no conflict in the contactless parameters of multiple NFC simulation cards in the target NFC simulation card, it is determined that there is no activation conflict in the multiple NFC simulation cards in the target NFC simulation card; if there is a conflict in the contactless parameters of multiple NFC simulation cards in the target NFC simulation card, it is determined that there is an activation conflict in the multiple NFC simulation cards in the target NFC simulation card.

[0052] As an example, if the target NFC simulation cards include the NFC Zhengzhou traffic simulation card and the NFC Shenzhen traffic simulation card, and there is a conflict in the contactless parameter selection responses in the NFC Zhengzhou traffic simulation card and the NFC Shenzhen traffic simulation card, it can be determined that there is an activation conflict among the multiple NFC simulation cards in the target NFC simulation card.

[0053] In some embodiments, the electronic device further includes an NFC chip, which is located at the hardware layer of the electronic device. The NFC chip can be Figure 1 Activating the target NFC simulation card may include: using the security chip to send a second activation instruction to the NFC chip, the second activation instruction including the composite contactless parameter; according to the second activation instruction, using the NFC chip to activate the target NFC simulation card. It is understandable that the NFC chip can replace or overwrite the contactless parameters of the NFC card in the NFC chip according to the composite contactless parameters.

[0054] In order to deepen the understanding of the activation method of the NFC simulation card in the embodiment of the present application, the following Figure 3 The architecture of the electronic device to which the activation method of the NFC simulated card is applied is described in detail with examples.

[0055] Figure 3 A possible architecture diagram of an electronic device provided in an embodiment of the present application. Figure 3 As shown, the electronic device 300 may include an application layer 310 , an application interface layer 320 , a security process service layer 330 and a hardware layer 340 .

[0056] The application layer 310 may include a security chip application, which may also be referred to as a security chip application. The security chip application may be, for example, a Wallet application. The application interface layer 320 is located between the application layer 310 and the security process service layer 330. The application interface layer 320 may include an application interface, which may be, for example, an open mobile application interface OMA. Data transmission between the application layer 310 and the security process service layer 330 may be achieved through the application interface layer 320. The security process service layer 330 has an encryption function, and the security process service layer 330 may be a TEE environment or a REE environment. The hardware layer 340 may include a security chip and an NFC chip. The security chip may be used to store data information of multiple NFC simulated cards, and the security chip may perform near field communication with an external card reader device through the NFC chip.

[0057] In some embodiments, the security chip application in the application layer 310 may include three NFC simulation cards, which may be, for example, a Shenzhen Transportation NFC simulation card, a Zhengzhou Transportation NFC simulation card, and an access control NFC simulation card, wherein the application identifier of the Shenzhen Transportation NFC simulation card may be AID1, the application identifier of the Zhengzhou Transportation NFC simulation card may be AID2, and the application identifier of the access control NFC simulation card may be AID3.

[0058] In some embodiments, the security chip application may include a UI interface. Figure 4 A possible UI interface diagram for a security chip application. Figure 4 , multiple NFC simulation cards in the electronic device (for example, including Shenzhen Transportation NFC simulation card, Zhengzhou Transportation NFC simulation card and access control NFC simulation card) can be displayed in the UI interface of the security chip application, and corresponding check boxes for multiple NFC simulation cards can be set. The user can select the target NFC simulation card through the check box, and then trigger the activation function button in the security application to generate an activation instruction for the target NFC simulation card. It is understandable that when the target NFC simulation card is activated, the activation function button can be converted to a deactivation function button to trigger the deactivation instruction of the target NFC simulation card.

[0059] Combination of the above Figure 3 and Figure 4 The architecture of the electronic device in the embodiment of the present application is illustrated by way of example. In order to deepen the understanding of the activation method of the NFC simulation card in the embodiment of the present application, the activation method of the NFC simulation card is applied to Figure 3 For example, the electronic equipment in Figure 5 The activation method of the NFC simulation card is described in detail with examples.

[0060] Figure 5The following is a flow chart of a method for activating an NFC simulated card provided in one embodiment of the present application. Figure 5 As shown, it may specifically include steps: S501 to S505.

[0061] In step S501: the target NFC simulation card is determined by using the security chip application, and the first activation instruction is sent to the application interface layer. The target NFC simulation card may include, for example, the Shenzhen Transportation NFC simulation card and the access control NFC simulation card, and both the Shenzhen Transportation NFC simulation card and the access control NFC simulation card are in a deactivated state. The first activation instruction includes the application identifiers (i.e., AID1 and AID3) of all NFC simulation cards in the target NFC simulation card.

[0062] In step S502: the validity of the first activation instruction is verified at the application interface layer, and in response to the first activation instruction being valid, the first activation instruction is transmitted to the security process service layer through the application interface layer.

[0063] In some embodiments, the legitimacy of the first activation instruction may refer to the correctness and / or validity of AID1 and AID3 carried by the first activation instruction.

[0064] In step S503: the first activation instruction is encrypted at the security process service layer to ensure data security, and at the same time, the encrypted first activation instruction is transmitted to the security chip.

[0065] In step S504: the encrypted first activation instruction is verified using the key in the security chip; if the encrypted first activation instruction passes the key verification, the security chip can be used to composite the contactless parameters of the target NFC simulation card to obtain composite contactless parameters. Then, the security chip is used to send a second activation instruction to the NFC chip, and the second activation instruction carries the composite contactless parameters of the target NFC simulation card.

[0066] In some embodiments, the security chip can obtain the contactless parameters of the Shenzhen Transportation NFC simulation card and the access control NFC simulation card according to AID1 and AID3.

[0067] In step S505: according to the second activation instruction, the target NFC simulation card is activated using the NFC chip. It can be understood that activating the target NFC simulation card may refer to replacing or overwriting the contactless parameters of the NFC card in the NFC chip according to the composite contactless parameters.

[0068] It is understandable that if the target NFC simulation card is activated, the user can deactivate it first when he wants to change the NFC simulation card. Figure 6 For the above Figure 5 The deactivation process of the target NFC simulation card after activation is completed is described in detail with an example. Figure 6 for Figure 5 Flow chart of the deactivation method of the target NFC simulated card. Figure 6 As shown, it may specifically include steps: S601 to S605.

[0069] In step S601: the security chip application sends a first deactivation instruction of the target NFC simulation card to the application interface layer. The first deactivation instruction includes the application identifier of the target NFC simulation card (ie, AID1 and AID3).

[0070] In step S602: the validity of the first deactivation instruction is verified at the application interface layer, and in response to the first deactivation instruction being valid, the first deactivation instruction is transmitted to the security process service layer through the application interface layer.

[0071] In some embodiments, the legitimacy of the first deactivation instruction may refer to the correctness and / or validity of AID1 and AID3 carried by the first deactivation instruction.

[0072] In step S603: the first deactivation instruction is encrypted at the security process service layer to ensure data security, and at the same time, the encrypted first deactivation instruction is transmitted to the security chip.

[0073] In step S604: the encrypted first deactivation instruction is verified using the key in the security chip; if the encrypted first deactivation instruction passes the key verification, the security chip can be used to send a second deactivation instruction to the NFC chip, and the second deactivation instruction carries the default contactless parameters of the NFC simulated card.

[0074] In step S605: according to the second deactivation instruction, the target NFC simulation card is deactivated by using the NFC chip. It can be understood that deactivating the target NFC simulation card may refer to replacing or overwriting the composite contactless parameters of the NFC card in the NFC chip according to the default contactless parameters. Of course, the composite contactless parameters of the NFC card in the NFC chip may also be directly deleted.

[0075] In some embodiments, the target NFC simulated card can be bound and activated at the same time, such as Figure 5 The activation method of the NFC simulation card shown in the figure. Of course, you can also use the separate activation method, first activate one NFC simulation card, then activate the next NFC simulation card, and so on. The following takes the Shenzhen Transportation NFC simulation card in an activated state and then activates the access control NFC simulation card as an example. Figure 7 A detailed example is given to illustrate the individual activation method of the target NFC simulation card.

[0076] Figure 7 for Figure 5Flow chart of the method for activating the target NFC simulated card separately. Figure 7 As shown, it may specifically include steps: S701 to S713.

[0077] In step S701: the user selects the access control NFC simulation card for activation, that is, determines the target NFC simulation card, and determines that the target NFC simulation card is the Shenzhen Transportation NFC simulation card and the access control NFC simulation card.

[0078] In step S702: after determining the target NFC simulation card, it is possible to detect whether there is an activation conflict with the target NFC card, that is, to detect whether there is a conflict between the contactless parameters of the Shenzhen Transportation NFC simulation card and the access control NFC simulation card.

[0079] In some embodiments, if there is no conflict in the contactless parameters of the Shenzhen Traffic NFC simulation card and the access control NFC simulation card, it is determined that there is no activation conflict in the target NFC simulation card, and the process jumps to step S703. If there is a conflict in the contactless parameters of the Shenzhen Traffic NFC simulation card and the access control NFC simulation card, it is determined that there is an activation conflict in the target NFC simulation card, and the process jumps to step S708.

[0080] In step S703: a first activation instruction is issued to the application interface layer.

[0081] It can be understood that, since the Shenzhen Transportation NFC simulation card is in an activated state, the first activation instruction includes the application identifiers of some NFC simulation cards in the target NFC simulation card, that is, the first activation instruction includes AID3 but does not include AID1.

[0082] In step S704: the legitimacy of the first activation instruction is verified at the application interface layer; in response to the first activation instruction being legitimate, the first activation instruction is transmitted to the security process service layer through the application interface layer.

[0083] In some embodiments, the legitimacy of the first activation instruction may refer to the correctness and / or validity of the AID3 carried by the first activation instruction.

[0084] In step S705: the first activation instruction is encrypted at the security process service layer to ensure data security, and at the same time, the encrypted first activation instruction is transmitted to the security chip.

[0085] In step S706: the encrypted first activation instruction is verified using the key in the security chip; if the encrypted first activation instruction passes the key verification, the security chip can be used to composite the contactless parameters of the target NFC simulation card to obtain composite contactless parameters. Then, the security chip is used to send a second activation instruction to the NFC chip, and the second activation instruction carries the composite contactless parameters of the target NFC simulation card.

[0086] In some embodiments, the security chip can obtain the contactless parameters of the access control NFC simulation card according to AID3, and then composite them with the contactless parameters of the activated Shenzhen Transportation NFC simulation card to obtain composite contactless parameters.

[0087] In step S707: according to the second activation instruction, the target NFC simulation card is activated using the NFC chip. It can be understood that activating the target NFC simulation card may refer to replacing or overwriting the contactless parameters of the NFC card in the NFC chip according to the composite contactless parameters.

[0088] In step S708: a third activation instruction and a third deactivation instruction are issued to the application interface layer.

[0089] In some embodiments, the third activation instruction includes AID3, and the third deactivation instruction includes AID1.

[0090] In step S709: verify the legitimacy of the third activation instruction and the third deactivation instruction at the application interface layer; in response to the third activation instruction being legal, transmit the third activation instruction to the security process service layer through the application interface layer; in response to the third deactivation instruction being legal, transmit the third deactivation instruction to the security process service layer through the application interface layer.

[0091] In some embodiments, the legitimacy of the third activation instruction may refer to the correctness and / or validity of AID3 carried by the third activation instruction; the legitimacy of the third deactivation instruction may refer to the correctness and / or validity of AID1 carried by the third deactivation instruction.

[0092] In step S710: the third activation instruction and the third deactivation instruction are encrypted at the security process service layer to ensure data security, and at the same time, the encrypted third activation instruction and the third deactivation instruction are transmitted to the security chip.

[0093] In step S711: the encrypted third activation instruction and the third deactivation instruction are verified using the key in the security chip; if the encrypted third deactivation instruction passes the key verification, the security chip can be used to send a fourth deactivation instruction to the NFC chip. The fourth deactivation instruction can carry the default contactless parameters of the NFC simulated card.

[0094] If the encrypted third activation instruction passes the key verification, the contactless parameters of the access control NFC simulation card can be obtained according to AID3, and then the fourth activation instruction is sent to the NFC chip using the security chip. The fourth activation instruction can carry the contactless parameters of the access control NFC simulation card.

[0095] In step S712: firstly, according to the fourth deactivation instruction, the Shenzhen Transportation NFC simulation card is deactivated, and then, the access control NFC simulation card is activated.

[0096] In step S713: end the current NFC simulated card activation process.

[0097] It should be noted that in Figure 5 The binding activation in can also include the judgment of the target NFC simulated card activation conflict. For details, please refer to Figure 7 The method for determining the activation conflict of the target NFC simulation card will not be described here.

[0098] In some embodiments, in order to deepen the understanding of the composite processing process of the contactless parameters of the target NFC simulation card in the embodiments of the present application, the following takes the traffic NFC simulation card, the access control NFC simulation card and the CCC car key NFC simulation card as examples. Figure 8 Provide detailed examples.

[0099] like Figure 8 As shown, in some embodiments, the traffic NFC simulation card includes an application identifier AID and contactless parameters. The AID of the NFC simulation card may be A000000632010105. The contactless parameters may include: UID, SAK, ATQA, ATS, etc. According to its application protocol, its necessary parameters may be determined as: AID, contactless parameter ATS, and contactless parameter SAK. Among them, the SAK of the traffic NFC simulation card may be 0x20, and the ATS of the traffic NFC simulation card may be 0x6700.

[0100] In some embodiments, the access control NFC simulation card includes AID and contactless parameters, and the contactless parameters may include: UID, SAK, ATQA, ATS, etc. According to its application protocol, its necessary contactless parameters can be determined to be UID, ATQA and SAK. Among them, the UID of the access control NFC simulation card can be A1B2C3D4, the ATQA of the access control NFC simulation card can be 0x0400, and the SAK of the access control NFC simulation card can be 0x08 / 0x18.

[0101] In some embodiments, the CCC car key NFC simulation card includes an AID and contactless parameters. The AID of the CCC car key NFC simulation card can be A000000123456. The contactless parameters can include: UID, SAK, ATQA, ATS, etc. According to its application protocol, its necessary parameter can be determined to be AID. That is to say, the CCC car key NFC simulation card generally does not have contactless parameters.

[0102] On the basis of the above application protocol, the contactless parameters of the traffic NFC simulation card, the access control NFC simulation card and the CCC car key NFC simulation card are composited to obtain their composite contactless parameters. The ATS in the composite contactless parameters can use the traffic NFC simulation card, the UID and ATQA in the composite contactless parameters can use the access control NFC simulation card, and the SAK in the composite contactless parameters can use the composite SAK of the traffic NFC simulation card and the access control NFC simulation card. On this basis, the composite contactless parameters can be used to simultaneously activate the traffic NFC simulation card, the access control NFC simulation card and the CCC car key NFC simulation card, so as to meet the changing application needs of users and improve the user experience.

[0103] It should be noted that the composite selection confirmation SAK of the traffic NFC simulation card and the access control NFC simulation card can be 0x28 / 0x38 (hexadecimal number). That is, 0x28=0x08+0x20, 0x38=0x18+0x20. It should be understood that in the application protocol of the NFC simulation card, 0x28 can cover 0x20 and 0x08, and 0x38 can cover 0x20 and 0x18. In other words, 0x28 / 0x38 can be applied to the data interaction between the traffic NFC simulation card and the access control NFC simulation card.
