[0027] Existing NFC card management devices can usually only read and write a single NFC physical card, and need to be carried around. This means that when users need to frequently use multiple different NFC cards, they have to carry multiple physical cards around, which is obviously not very convenient.

[0028] Based on the above problems, the NFC card management device provided in the embodiment of the present application includes a control module, a selection module, a network processing module and multiple NFC card reading and writing modules. In actual use, the user uses an NFC card simulation device (such as a smart phone) to send a card reading request to the server, and the server interacts with the NFC card management device through the INTERNET, that is, the server interacts with the control module through the network processing module, and sends a management signal containing specific NFC card information to the control module. The control module receives and parses the NFC card operation requirements contained in the management signal, and then sends a control signal to the selection module. The selection module connects the corresponding NFC card reading and writing module according to the control signal, so that the NFC card reading and writing module performs reading and writing operations on the corresponding NFC physical card. When the NFC card reading and writing module completes the reading and writing operations on the corresponding NFC physical card, the NFC card reading and writing module transmits the data to the control module, and the control module transmits it back to the server through the network processing module. Finally, the server gives the user corresponding feedback through the NFC card simulation device to meet the user's needs. From this, we can see that the entire process enables users to remotely manage NFC cards at physical locations through smart devices, which simplifies the operation process. Users no longer need to carry multiple NFC physical cards with them, improving convenience and safety of use.

[0029] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.

[0030] Figure 1 FIG. 1 shows a block diagram of an NFC card management device 10 provided in an embodiment of the present application. Figure 1 As shown, the NFC card management device 10 includes a control module 101, a selection module 102, a network processing module 103 and a plurality of NFC card reading and writing modules 104. The selection module 102 is electrically connected to the control module 101 and all the NFC card reading and writing modules 104 respectively, the control module 101 is used to exchange information with the server 20 through the network processing module 103, and each NFC card reading and writing module 104 is used to communicate with the corresponding NFC physical card.

[0031] Specifically, in actual use, the user uses the NFC card simulation device 30 (such as a smart phone) to send a card reading request to the server 20, and the server 20 interacts with the NFC card management device through the INTERNET, that is, the server 20 interacts with the control module 101 through the network processing module 103, and sends a management signal containing specific NFC card information to the control module 101. The control module 101 receives and parses the NFC card operation requirements contained in the management signal, and then sends a control signal to the selection module 102. The selection module 102 connects the corresponding NFC card reading and writing module 104 according to the control signal, so that the NFC card reading and writing module 104 performs a reading and writing operation on the corresponding NFC physical card. When the NFC card reading and writing module 104 completes the reading and writing operation on the corresponding NFC physical card, the NFC card reading and writing module 104 transmits the data to the control module 101, and the control module 101 then transmits it back to the server 20 through the network processing module 103. Finally, the server 20 gives the user corresponding feedback through the NFC card simulation device 30 to meet the user's needs. From this, we can see that the entire process enables users to remotely manage NFC cards at physical locations through smart devices, which simplifies the operation process. Users no longer need to carry multiple NFC physical cards with them, improving convenience and safety of use.

[0032] It should be noted that NFC is a short-range wireless communication technology that allows data exchange between electronic devices. When NFC devices work within a very short distance (usually a few centimeters), data transmission is achieved through electromagnetic fields. The card reading signal received by the server 20 may contain card information or a request for initiating further data exchange.

[0033] Exemplarily, the NFC card reading and writing module 104 can read and write subway cards, bus cards, access control cards or bank cards, etc., which are not limited here.

[0034] In one embodiment of the present application, the selection module 102 includes a multi-way selection switch, a first end of the multi-way selection switch is electrically connected to the control module 101, and multiple second ends of the multi-way selection switch are electrically connected to multiple NFC card reading and writing modules 104 in a one-to-one correspondence.

[0035] Specifically, after the first end of the multi-way selection switch receives the control signal output by the control module 101, the multi-way selection switch connects the corresponding NFC card reading and writing module 104 according to the control signal, so that the NFC card reading and writing module 104 performs reading and writing operations on the corresponding NFC physical card.

[0036] It should be noted that the control signal received by the selection module 102 may be a chip selection signal. Therefore, the selection module 102 can only select one NFC card reading and writing module 104, that is, only one NFC physical card can be read and written at a time. This design can prevent wireless signal crosstalk between different NFC physical cards.

[0037] In one embodiment of the present application, the network processing module 103 includes a network switching chip and a network interface. The first end of the network switching chip is electrically connected to the control module 101, and the second end of the network switching chip is electrically connected to the network interface. The network interface is used to interact with the server 20 for information.

[0038] Specifically, the network switching chip is a core component in the network processing module 103 and is used for exchanging network data. The network switching chip can receive and process network communication instructions and data from the control module 101 and pass the processed data to the network interface to exchange information with the server 20.

[0039] Exemplarily, a network interface typically includes a physical interface, such as an RJ-45 port (for Ethernet connection) or a USB network adapter, and a wireless interface, such as a Wi-Fi or Bluetooth module.

[0040] In one embodiment of the present application, the NFC card reading and writing module 104 includes a first antenna and an NFC chip, the first end of the NFC chip is electrically connected to the first antenna, the second end of the NFC chip is electrically connected to the selection module 102, and the first antenna is used to communicate with the corresponding NFC physical card.

[0041] Specifically, the first antenna is an interface for the NFC card reader / writer module 104 to communicate wirelessly with the NFC physical card. When the NFC physical card is inserted into the NFC card reader / writer module 104, the first antenna generates an electromagnetic field, which interacts with the NFC chip in the physical card so that the NFC chip decodes the signal transmitted by the first antenna. That is, the first antenna can receive signals from the NFC physical card and pass these signals to the NFC chip. Similarly, the first antenna can also send out the signal generated by the NFC chip for the NFC physical card to receive.

[0042] In one embodiment of the present application, the NFC card reading and writing module 104 further includes a card slot, and the card slot is used to place a corresponding NFC physical card.

[0043] Specifically, the card slot provides a stable physical placement for the NFC physical card, ensuring that the NFC physical card will not move, and improving the reliability and stability of the communication between the NFC physical card and the NFC card reader / writer module 104. The inner wall of the card slot is coated with a metal layer for shielding to prevent wireless signal interference between different NFC physical cards. At the same time, the design of the card slot can also provide a certain degree of dust and shock protection to protect the NFC physical card from the external environment. In addition, the card slot can also facilitate users to easily place and remove the NFC physical card, improving the user's convenience.

[0044] In one embodiment of the present application, the NFC card management device 10 selects any NFC card reading / writing module 104 among all NFC card reading / writing modules 104 through the selection module 102 at the same time to communicate using the SPI mode.

[0045] Specifically, the selection module 102 can select any one of the SPI communication interfaces of multiple NFC card reader / writer modules 104 to connect to the master device, and the number of selected modules can be expanded according to the number of supported NFC cards. The SPI bus can be used for high-speed data transmission. The SPI bus allows one master device to connect to multiple slave devices, which can be achieved by adding chip select lines of the slave devices. This provides flexibility for system design, that is, more NFC card reader / writer modules 104 can be expanded.

[0046] In one embodiment of the present application, the NFC card management device further includes a storage module, and the storage module is electrically connected to the control module 101 .

[0047] Specifically, the storage module is used to store relevant information and historical operation records of the NFC card, such as card number, access control data, transaction history, etc., for easy query and management at any time. At the same time, the storage module can also be used as a data backup. If a system failure occurs, it can be quickly restored to a normal state, ensuring the security of the data and the stability of the system operation. In addition, the storage module may also be used to store user authority settings, so that the control module 101 can authorize and verify the user's operation based on the stored authority information.

[0048] like Figure 2 As shown, the present application also discloses an NFC card management system 100, including a server 20, an NFC card simulation device 30 and the above-mentioned NFC card management device 10, and both the NFC card simulation device 30 and the NFC card management device 10 interact with the server.

[0049] Specifically, in actual use, the user uses the NFC card simulation device 30 (such as a smart phone) to send a card reading request to the server 20. The server 20 exchanges information with the control module 101 through the network processing module 103, and sends a management signal containing specific NFC card information to the NFC card management device 10. The NFC card management device 10 receives and parses the NFC card operation requirements contained in the management signal, and then performs read and write operations on the corresponding NFC physical card. When the NFC card management device 10 completes the read and write operations on the corresponding NFC physical card, the NFC card management device 10 returns the data to the server 20. Finally, the server 20 gives the user corresponding feedback through the NFC card simulation device 30 to meet the user's needs. It can be seen that the whole process enables users to remotely manage NFC cards at physical locations through smart devices, simplifies the operation process, and users do not need to carry multiple NFC physical cards with them, which improves the convenience and safety of use.

[0050] Exemplarily, the NFC card management device 10 can be fixedly set at a preset location, for example, a user's home. The NFC card simulation device 30 can be a portable WIFI device, a mobile phone, a tablet computer, a laptop computer, a smart wearable device, and other terminal devices. When the NFC card simulation device 30 is a portable WIFI device, the portable WIFI device can also include a WIFI module. The WIFI module can be used to provide network services for other smart terminal devices (for example, mobile phones). Therefore, even if the user needs to frequently use multiple different NFC cards, there is no need to carry multiple NFC physical cards with him, but only needs to carry the NFC card simulation device 30 (for example, a mobile phone), thereby improving the convenience of the user.

[0051] It should be noted that the NFC physical card stores the card information of the NFC card, which includes but is not limited to a non-encrypted NFC card and an encrypted NFC card, wherein the non-encrypted NFC card refers to an NFC card whose card information is not encrypted, and the encrypted NFC card refers to an NFC card whose card information is encrypted.

[0052] In one embodiment of the present application, both the NFC card management device 10 and the NFC card emulation device 30 communicate with the server 20 via the INTERNET.

[0053] Specifically, the INTERNET provides an efficient data transmission and communication method. The NFC card management device 10 and the NFC card simulation device 30 can communicate with the server 20 via the INTERNET to quickly transmit data. At the same time, the NFC card management device 10 and the NFC card simulation device 30 can achieve wireless remote communication with the server 20, thereby achieving a wider range of connections.

[0054] In one embodiment of the present application, the NFC card emulation device 30 includes a second antenna, and the second antenna is used to communicate with a card reading device.

[0055] Specifically, the second antenna is used as a medium for wireless communication, and is used to receive wireless signals from the card reader device and send signals to the card reader device to achieve wireless communication between the NFC card emulation device 30 and the card reader device. Specifically, the card reader device interacts with the NFC card emulation device 30 by sending RF signals. The second antenna can receive these RF signals and pass the received RF signals to the circuit inside the NFC card emulation device 30 for processing. At the same time, the NFC card emulation device 30 sends a signal to the card reader device through the second antenna to respond to the request or provide data.

[0056] It should be noted that the card reader can be set up in a fixed place (for example, a gate at a subway station) or a fixed position (for example, a bus card reader) to read the card information of the NFC card and use the card information for services such as deductions and unlocking.

Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
