[0032] Optionally, in the electronic device, a processing circuit 50 is further provided between the RF chip 10 and the RF antenna 20, and the processing circuit 50 can perform signal processing such as filtering and amplification on the RF signal emitted by the RF chip 10.

[0033] Figure 3 is a flow chart of a method for detecting a card provided by the present disclosure, with reference to Figure 3 The present disclosure provides a method for detecting a card, which is applied to an electronic device. The method includes:

[0034] Step S100, detecting whether a card exists.

[0035] Step S200: If a card exists, determine whether the card is a physical card or a virtual card.

[0036] Specifically, the method for detecting a card provided by the embodiment of the present disclosure can first detect whether there is a card in the surrounding environment. When the presence of a card is detected, it is determined whether the card is a physical card or a virtual card, thereby determining the type of the card. When it is determined that the card is a physical card, the surrounding environment can be changed to avoid the physical card being in a special environment, thereby preventing the physical card from being damaged.

[0037] In some optional embodiments, a wireless charging chip and a wireless charging antenna connected to the wireless charging chip are provided in the electronic device; and the method further includes:

[0038] If the card is a physical card, the wireless charging chip is controlled not to start transmitting a charging signal to the wireless charging antenna or to stop transmitting a charging signal to the wireless charging antenna.

[0039] Specifically, when a wireless charging chip and a wireless charging antenna connected to the wireless charging chip are provided in an electronic device, the wireless charging chip can transmit a charging signal to the wireless charging antenna connected thereto, so that the wireless charging antenna can generate corresponding electromagnetic waves according to the charging signal and transmit them out. These electromagnetic waves will induce current in the antenna of the receiving device, thereby realizing wireless charging. Since the wireless charging antenna needs to send high-frequency energy pulse waves during the charging process, if a physical card is mistakenly placed in this environment, the physical card will be burned and cannot be used.

[0040] It should be noted that this embodiment exemplarily shows the research conducted by the inventor based on the problem of damage to the physical card in a wireless charging environment. Similarly, in other embodiments of the present disclosure, in other special environments, when the physical card is damaged, the solution of the above embodiment can also be adopted, and the present disclosure will not go into details here.

[0041] By using the card detection method provided in the embodiment of the present disclosure, when it is confirmed that the card is a physical card, the wireless charging chip is controlled not to start transmitting a charging signal to the wireless charging antenna or to stop transmitting a charging signal to the wireless charging antenna, so as to avoid the physical card being placed in a wireless charging environment, causing the physical card to be burned and unusable.

[0042] In some optional embodiments, the method further includes: if the card is a virtual card, controlling the wireless charging chip to start transmitting a charging signal to the wireless charging antenna or continue transmitting a charging signal to the wireless charging antenna.

[0043] Specifically, when the virtual card is placed in a wireless charging environment, it will not be affected.

[0044] By using the card detection method provided by the embodiment of the present disclosure, when it is confirmed that the card is a virtual card, the wireless charging chip is controlled to start transmitting a charging signal to the wireless charging antenna or continue transmitting a charging signal to the wireless charging antenna, thereby not interrupting the charging process of the corresponding device.

[0045] Figure 4 is a flow chart of another method for detecting a card provided by the present disclosure, with reference to Figure 4 In some optional embodiments, a radio frequency chip and a radio frequency antenna connected to the radio frequency chip are provided in the electronic device;

[0046] Step S100, detecting whether a card exists includes:

[0047] Step S110, waking up the RF chip and controlling the RF chip to transmit an initial RF signal to the RF antenna.

[0048] Specifically, the RF chip can be initialized first, and then awakened, and the RF chip can be controlled to transmit an initial RF signal to the RF antenna, so that the RF antenna can form a corresponding RF field according to the initial RF signal, and the RF field can provide power to the physical card.

[0049] Step S120, controlling the radio frequency chip to transmit a card-seeking radio frequency signal to the radio frequency antenna.

[0050] Specifically, the RF chip is controlled to transmit a card-seeking RF signal to the RF antenna, so that the RF antenna can form a corresponding RF field according to the card-seeking RF signal. If there is a card nearby, the card will generate a feedback signal when it receives the corresponding electromagnetic wave.

[0051] Step S130, controlling the radio frequency chip to receive a feedback signal, and if the radio frequency chip receives the feedback signal, it is determined that there is a card.

[0052] Optionally, the RF chip includes an analog-to-digital conversion module, which can receive the feedback signal and convert the feedback signal into a digital signal.

[0053] Specifically, by controlling the RF chip to transmit a card-seeking RF signal to the RF antenna, whether the card is a physical card or a virtual card, a feedback signal will be sent back. If the RF chip receives the feedback signal, it can be determined that there is a card nearby.

[0054] Continue to refer Figure 4 In some optional embodiments, step S200, determining whether the card is a physical card or a virtual card includes:

[0055] Step S210, controlling the radio frequency chip to stop transmitting the card-seeking radio frequency signal to the radio frequency antenna.

[0056] Specifically, after determining that there is a card nearby, the radio frequency chip is controlled to stop transmitting the card-seeking radio frequency signal to the radio frequency antenna. Accordingly, the radio frequency antenna is closed according to the radio frequency field formed by the card-seeking radio frequency signal.

[0057] Step S220: After the first set time, the RF chip is controlled to transmit a card-seeking RF signal to the RF antenna again.

[0058] Specifically, within the first set time, the control RF chip stops transmitting the card-seeking RF signal to the RF antenna. Thus, the physical card cannot be powered by the RF field. After the first set time, the control RF chip transmits the card-seeking RF signal to the RF antenna again, and the RF antenna forms a corresponding RF field based on the card-seeking RF signal and turns on.

[0059] Optionally, the first set time may be adjusted based on the card-seeking radio frequency signal, that is, the first set time may be adjusted accordingly for different card-seeking radio frequency signals.

[0060] Step S230, controlling the radio frequency chip to receive the feedback signal.

[0061] Step S240, comparing whether the two feedback signals are the same. If the two feedback signals are the same, it is determined that the card is a virtual card. If the two feedback signals are different, it is determined that the card is a physical card.

[0062] Specifically, it is necessary to provide power to the physical card through the radio frequency field. The virtual card is usually set in a mobile device, and the mobile device is provided with a power supply. It is not necessary to provide power to the virtual card through the radio frequency field. Within the first set time, the radio frequency chip is controlled to stop transmitting the card-seeking radio frequency signal to the radio frequency antenna, that is, the radio frequency antenna cannot form a radio frequency field within the first set time. Subsequently, the radio frequency chip is controlled to transmit the card-seeking radio frequency signal to the radio frequency antenna again. The physical card will not immediately resume transmitting the feedback signal as the radio frequency field is restored, while the simulated card will immediately resume transmitting the feedback signal as the radio frequency field is restored, and it will remain the same as the previous feedback signal. At this time, the card can be distinguished as a physical card or a virtual card by comparing whether the two feedback signals are the same. If the two feedback signals are the same, it indicates that the card is a virtual card. If the two feedback signals are different, it indicates that the card is a physical card.

[0064] The detection unit 60 is used to detect whether a card exists;

[0065] The determination unit 70 is used to determine whether the card is a physical card or a virtual card when a card exists.

[0066] Specifically, the device for detecting cards provided by the embodiment of the present disclosure can first detect whether there is a card in the surrounding environment.

When it is determined that the card is a physical card, the surrounding environment can be changed to avoid the physical card being in a special environment, thereby preventing the physical card from being damaged.
