Compared with the defect that multiple communication interfaces exist in the related art and concurrent service interaction is independent, the embodiment of the application can effectively guarantee the integrity of service interaction on each communication interface of the active smart card under the condition that multiple communication interfaces of the active smart card are independent, and avoid transaction failure of the active smart card.

[0039] The embodiment of the application is further described below with reference to the drawings.

[0040] Reference Figure 1 , Figure 1 is a module schematic diagram of the active smart card provided by the embodiment of the application, and the embodiment of the application provides an active smart card 100, comprising:

[0041] a contact interface 110, the contact interface 110 is used for being communicatively connected with a card reader 200;

[0042] a radio frequency antenna 120, the radio frequency antenna 120 is used for being communicatively connected with the card reader 200;

[0043] an MCU 130, the MCU 130 is provided with an SPI interface;

[0044] a smart card chip 140, the smart card chip 140 is electrically connected with the SPI interface, the contact interface 110 and the radio frequency antenna 120 respectively;

[0045] a communication module 150, the communication module 150 is electrically connected with the MCU 130, and the communication module 150 is used for being communicatively connected with the card reader 200;

[0046] a power management module 160, the power management module 160 is electrically connected with the contact interface 110, the radio frequency antenna 120, a detection pin of the MCU 130 and the smart card chip 140 respectively;

[0047] wherein, in the case that the contact interface 110 or the radio frequency antenna 120 is triggered, the detection pin outputs a low level, and in the case that the contact interface 110 or the radio frequency antenna 120 is not triggered, the detection pin outputs a high level.

[0048] It can be understood that in the case that the contact interface 110 or the radio frequency antenna 120 is triggered, that is, the active smart card 100 performs a card swiping operation (contact card swiping) through the contact interface 110 to interact with the card reader 200, or the active smart card 100 performs a card swiping operation (non-contact card swiping) through the radio frequency antenna 120 to interact with the card reader 200, the detection pin outputs a low level, and the power management module 160 cannot supply power to the MCU 130, so that when the active smart card 100 interacts with the card reader 200 through the contact interface 110 or the radio frequency antenna 120, the MCU 130 cannot realize the business interaction with the card reader 200 through the communication module 150, and the MCU 130 also cannot interact with the smart card chip 140 through the SPI interface; in the case that the contact interface 110 or the radio frequency antenna 120 is not triggered, that is, the active smart card 100 does not perform the contact card swiping operation and the non-contact card swiping operation, the detection pin outputs a high level, and the power management module 160 supplies power to the MCU 130, so that the MCU 130 can interact with the card reader 200 through the communication module 150, or the MCU 130 can interact with the smart card chip 140 through the SPI interface. Since the contact card swiping and the non-contact card swiping cannot be performed at the same time, therefore, the embodiment of the present application can effectively guarantee the integrity of the business interaction on each communication interface of the active smart card 100 in the case that the active smart card 100 has multiple independent communication interfaces, and avoid transaction failure of the active smart card 100.

[0049] It can be understood that in the process of the digital renminbi business process, the transaction process must be strictly in accordance with the process, otherwise the transaction will fail, and the digital renminbi business process is mainly based on data interaction between the active smart card 100 and the card reader 200. However, the smart card chip 140 of the current active smart card 100 is connected with the radio frequency antenna 120 and the contact interface 110, and the smart card chip 140 is electrically connected with the MCU 130 through the SPI interface. The input and output of the multiple communication interfaces are independent (that is, the input and output of the radio frequency antenna 120, the contact interface 110 and the SPI interface are independent of each other), and in the case that the card reader 200 interacts with the smart card chip 140 through the radio frequency antenna 120 or the contact interface 110 of the active smart card 100, the MCU 130 may also interact with the smart card chip 140 through the SPI interface. The concurrent business interaction operation of multiple communication interfaces may exist a communication interface that interrupts the digital currency transaction business logic on another communication interface, thereby causing the smart card chip 140 transaction business disorder, thereby causing the transaction failure of the active smart card 100. Based on this, the active smart card 100 provided by the embodiment of the present application includes a contact interface 110, the contact interface 110 is used for communication connection with the card reader 200; a radio frequency antenna 120, the radio frequency antenna 120 is used for communication connection with the card reader 200; an MCU 130, the MCU 130 is provided with an SPI interface; a smart card chip 140, the smart card chip 140 is electrically connected with the SPI interface, the contact interface 110 and the radio frequency antenna 120 respectively; a communication module 150, the communication module 150 is electrically connected with the MCU 130, and the communication module 150 is used for communication connection with the card reader 200; a power management module 160, the power management module 160 is electrically connected with the contact interface 110, the radio frequency antenna 120, the detection pin of the MCU 130 and the smart card chip 140 respectively. Based on the technical scheme of the embodiment of the present application, in the case that the contact interface 110 or the radio frequency antenna 120 is triggered, the detection pin is controlled to output low level, and in the case that the contact interface 110 or the radio frequency antenna 120 is not triggered, the detection pin is controlled to output high level. Compared with the defect of concurrent business interaction of multiple communication interfaces with independent input and output in the related art, the embodiment of the present application can effectively guarantee the integrity of the business interaction on each communication interface of the active smart card 100 in the case of independent multiple communication interfaces of the active smart card 100, and avoid the transaction failure of the active smart card 100.

[0050] It should be noted that the embodiment of the present application does not limit the specific type of MCU 130, and the MCU 130 can be an STM32 chip. Using the STM32 chip can effectively reduce the manufacturing cost of the active smart card 100.

[0051] It should be noted that the embodiments of the present application do not limit the specific working frequency of the radio frequency antenna 120, which can be determined by the person skilled in the art according to the actual needs.

[0052] It should be noted that the embodiments of the present application do not limit the specific structure of the radio frequency antenna 120 and the contact interface 110. The radio frequency antenna 120 can be an ISO14443 protocol radio frequency antenna 120, and the contact interface 110 can be an ISO7816 protocol interface. The person skilled in the art can determine according to the actual needs.

[0053] It should be noted that the embodiments of the present application do not limit the specific structure of the communication module 150, which can be a Bluetooth module or a WiFi module. The person skilled in the art can determine according to the actual needs.

[0054] Reference Figure 2 In an embodiment, the power management module 160 includes:

[0055] The rectifier and voltage stabilizing module 161 is electrically connected to the contact interface 110, the radio frequency antenna 120, and the smart card chip 140, respectively.

[0056] The MCU power supply module 162;

[0057] The transistor Q1 has its base electrically connected to the output terminal of the rectifier and voltage stabilizing module 161, its collector electrically connected to the power supply module and the detection pin, respectively, and its emitter grounded.

[0058] It should be noted that the embodiments of the present application do not limit the specific type of the transistor Q1, which can be, for example, Figure 2 The transistor Q1 of the present embodiment is an NPN type transistor Q1, and can also be a PNP type transistor Q1.

[0059] It can be understood that when the active smart card 100 interacts with the card reader 200 through the contact interface 110 or the radio frequency antenna 120, the induced current obtained by the radio frequency antenna 120 is converted into direct current by the rectifier and voltage stabilizing module 161, or the current received by the contact interface 110 is converted into direct current by the rectifier and voltage stabilizing module 161, and then the direct current is input to the base of the triode Q1, so that the collector and the emitter of the triode Q1 are short-circuited, so that the detection pin of the MCU 130 detects a low level, and the power management module 160 cannot supply power to the MCU 130, so that when the active smart card 100 interacts with the card reader 200 through the contact interface 110 or the radio frequency antenna 120, the MCU 130 cannot realize the business interaction with the card reader 200 through the communication module 150, and the MCU 130 cannot also interact with the smart card chip 140 through the SPI interface; in the case that the contact interface 110 or the radio frequency antenna 120 is not triggered, that is, the active smart card 100 does not perform the contact card swiping and the non-contact card swiping, the base of the triode Q1 detects a low voltage, so that the collector and the emitter of the triode Q1 are open-circuited, so that the detection pin of the MCU 130 detects a high level, and the power management module 160 supplies power to the MCU 130, so that the MCU 130 can interact with the card reader 200 through the communication module 150, or the MCU 130 can interact with the smart card chip 140 through the SPI interface. Since the contact card swiping and the non-contact card swiping cannot be performed at the same time, the embodiment of the present application can effectively guarantee the integrity of the business interaction on each communication interface of the active smart card 100 in the case that the active smart card 100 has multiple independent communication interfaces, and avoid transaction failure of the active smart card 100.

[0060] It should be noted that the embodiment of the present application does not limit the specific structure of the rectifier and voltage stabilizing module 161, which can be as shown in Figure 2 The rectifier and voltage stabilizing module 161 includes a first diode D1, a second diode D2, a third diode D3, a fourth diode D4, a voltage stabilizing diode D5, a first capacitor C1 and a second capacitor C2, wherein the cathode of the second diode D2 is electrically connected with the anode of the first diode D1, the cathode of the fourth diode D4 is electrically connected with the anode of the third diode D3, the cathode of the third diode D3 is electrically connected with the cathode of the first diode D1, the anode of the fourth diode D4 is grounded, the anode of the second diode D2 is grounded, the cathode of the voltage stabilizing diode D5 is electrically connected with the cathode of the third diode D3, the anode of the voltage stabilizing diode D5 is grounded, the first end of the first capacitor C1 is electrically connected with the cathode of the voltage stabilizing diode D5, the second end of the first capacitor C1 is grounded, the first end of the second capacitor C2 is electrically connected with the first end of the first capacitor C1, and the second end of the second capacitor C2 is grounded.

[0061] It should be noted that the embodiments of this application do not limit the specific types and structures of the first diode D1, the second diode D2, the third diode D3, the fourth diode D4, the Zener diode D5, the first capacitor C1, and the second capacitor C2. Those skilled in the art can select according to the actual situation.

[0062] It is understandable that the number of the above-mentioned components can be increased or decreased according to actual needs. The specific values ​​can be adjusted according to the specific situation of the active smart card 100, which will not be elaborated here.

[0063] Understandably, the rectifier and voltage regulator module 161 with Zener diode D5 can filter out the ripple in the DC power and maintain the voltage stability of the DC power.

[0064] In addition, such as Figure 3 As shown, Figure 3 This is a flowchart illustrating the steps of a service control method based on an active smart card according to another embodiment of this application. Another embodiment of this application also provides a service control method based on an active smart card, applied to the active smart card provided in the above embodiments. This method includes, but is not limited to, the following steps:

[0065] In step S310, when the contact interface 110 or the radio frequency antenna 120 is triggered, the control detection pin outputs a low level.

[0066] or,

[0067] In step S320, if the contact interface 110 or the RF antenna 120 is not triggered, the control detection pin outputs a high level so that the MCU 130 can perform business interaction with the smart card chip 140 through the SPI interface, or the MCU 130 can perform business interaction with the card reader 200 through the communication module 150.

[0068] It can be understood that based on the hardware structure of the active smart card with independent input and output of multiple communication interfaces provided in the above embodiment, in the case that the contact interface 110 or the radio frequency antenna 120 is triggered, that is, the active smart card performs card swiping through the contact interface 110 (contact card swiping) and interacts with the card reader 200, or the active smart card performs card swiping through the radio frequency antenna 120 (non-contact card swiping) and interacts with the card reader 200, the detection pin is controlled to output a low level, so that the power management module 160 cannot supply power to the MCU 130, so that when the active smart card interacts with the card reader 200 through the contact interface 110 or the radio frequency antenna 120, the MCU 130 cannot realize the business interaction with the card reader 200 through the communication module 150, and the MCU 130 cannot also interact with the smart card chip 140 through the SPI interface; in the case that the contact interface 110 or the radio frequency antenna 120 is not triggered, that is, the active smart card does not perform contact card swiping and non-contact card swiping, the detection pin is controlled to output a high level, so that the power management module 160 supplies power to the MCU 130, so that the MCU 130 can interact with the card reader 200 through the communication module 150, or the MCU 130 can interact with the smart card chip 140 through the SPI interface. Thus, the priority of the contact interface 110, the radio frequency antenna 120, and the SPI interface is allocated respectively, the contact interface 110 and the radio frequency antenna 120 have the highest priority and the same priority (contact card swiping and non-contact card swiping cannot be performed at the same time), the business interaction of the MCU 130 corresponding to the SPI interface has the lowest priority, thereby ensuring the integrity of the business interaction corresponding to each communication interface, and effectively avoiding the business interaction failure caused by concurrent business interaction of the independent input and output of multiple communication interfaces.

[0069] In addition, as shown in Figure 4 Figure 4 is a step flowchart of the business control method based on the active smart card provided in another embodiment of the present application, and the method further includes but is not limited to the following steps:

[0070] Step S410, in the case that the MCU 130 interacts with the smart card chip 140 through the SPI interface, when it is detected that the contact interface 110 or the radio frequency antenna 120 is triggered, the detection pin is controlled to output a low level;

[0071] Step S420, in the case that the MCU 130 interacts with the card reader 200 through the communication module 150, when it is detected that the contact interface 110 or the radio frequency antenna 120 is triggered, the detection pin is controlled to output a low level.

[0072] ​It can be understood that, in the case that the MCU 130 interacts with the smart card chip 140 through the SPI interface, or in the case that the MCU 130 interacts with the card reader 200 through the communication module 150, when it is detected that the contact interface 110 or the radio frequency antenna 120 is triggered, the control detection pin outputs a low level, that is, the contact interface 110 and the radio frequency antenna 120 correspond to the highest priority of the business process, and in the process of the MCU 130 interacting with the business, if it is detected that the contact interface 110 or the radio frequency antenna 120 is triggered, the business interaction process on the MCU 130 side is immediately exited, and after the business interaction corresponding to the contact interface 110 or the radio frequency antenna 120 is completed, the business processing on the MCU 130 side is performed again.

[0073] In addition, with reference to Figure 5 An embodiment of the present application further provides an active smart card 500, which comprises a memory 510, a processor 520 and a computer program stored in the memory 510 and executable on the processor 520.
