[0002] Technical Field The present disclosure relates to the field of communication technologies, and particularly to passive near-field communication devices, methods and apparatuses.

Background Art

[0003] Currently, NFC (Near Field Communication) payment methods mainly include bus / subway payments and some bank card payment methods. On the device side, NFC mainly operates in an active mode, recognizing bus / subway cards, some bank cards, and emulation cards on mobile phones, and deducting to complete offline payments. However, for scenarios where small and medium-sized merchants cannot be powered on 24 hours a day, even if a battery power supply method is adopted, there are still deduction devices that run out of power. Therefore, in order to realize communication and complete payments at this time, the deduction device side needs to adopt a passive mode. In addition, regarding the lack of compatibility between some mobile phones and the card emulation mode of independent systems, considering this part of users, this deduction device also needs to operate in a passive mode.

[0030] The present application will be described in more detail below through drawings and embodiments. These descriptions will make the features and advantages of the present application clearer.

[0031] The term “exemplary” as used herein means “used as an example, embodiment, or explanatory example.” None of the embodiments described herein as “exemplary” are necessarily to be interpreted as superior to or better than other embodiments. While various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise noted.

[0032] Furthermore, the technical features of the different embodiments of this application described below may be combined with each other, as long as they do not constitute a conflict.

[0033] To better illustrate the embodiments of the present invention, technical terms related to the embodiments of the present invention are explained below.

[0034] NFC: A short-range, high-frequency wireless communication technology.

[0035] NFC Active Mode: In active mode, the NFC terminal functions as a card reader, emitting a radio frequency field to recognize and read / write passive NFC device information.

[0036] NFC Passive Mode (Card Emulation): In this mode, the NFC-enabled device is emulated as a card and passively responds only to radio frequency fields emitted from other devices, allowing information to be read / written.

[0037] LPCD (Low Power Card Detection) mode: When a mobile phone detects an NFC slave device, it enters a low power mode after a certain time interval following unlocking to conserve power, and the detected card also enters LPCD mode.

[0038] Normal card detection mode: To increase the speed and success rate of NFC, the mobile phone maintains full power card detection for a predetermined time after unlocking, which is the normal card detection mode. Both the LPCD and normal detection modes mentioned above use a 13.56MHz sine wave emitted from the mobile phone; only the transmission time and amplitude differ, and the energy is coupled through a coil.

[0039] In this embodiment, a passive short-range communication device is provided, and Figure 1 is a configuration diagram of the passive short-range communication device according to an embodiment of this disclosure, as shown in Figure 1, It is equipped with a wake-up tuning coil and a communication antenna coil.

[0040] This passive near-field communication device also includes an NFC chip (not shown in Figure 1). This NFC chip can receive commands transmitted from the card reader device via a communication antenna and perform read / write operations according to the commands.

[0041] The wake-up tuning coil described above is a bare wire coil, and its resonance point is the same as the carrier frequency band of the card reader device.

[0042] This bare wire coil may be an LC oscillator circuit not connected to an NFC chip. The card reader device may be a mobile phone with NFC functionality.

[0043] The above-mentioned communication antenna coil is connected to the NFC chip and is tuned to the carrier frequency band of the card reader device. In this context, "connected" refers to the communication antenna coil being connected to the NFC chip.

[0044] The resonance point of the wake-up tuning coil and the carrier frequency band of the card reader device may be 13.56 MHz.

[0045] The wake-up tuning coil described above is used to couple with the antenna of the card reader device when it is in close proximity to the antenna of the card reader device, thereby disabling the low-power card detection mode of the card reader device.

[0046] After the low-power card detection mode of the above card reader device is deactivated, it can enter full-power card detection mode.

[0047] The card reader device may wake up the full-power card detection mode by approaching the wake-up tuning coil in low-power card detection mode and inducing a magnetic field in the wake-up tuning coil.

[0048] The above-mentioned communication antenna coil is used to communicate with the card reader device in the full-power card detection mode of the card reader device.

[0049] This communication antenna coil may generate load modulation via the NFC chip and complete communication with the card reader device.

[0050] In the embodiments of this disclosure, the wake-up tuning coil is a bare wire coil, the resonance point of the wake-up tuning coil is the same as the carrier frequency band of the card reader device, the communication antenna coil is connected to the NFC chip and tuned to the carrier frequency band of the card reader device, the wake-up tuning coil is used to couple with the antenna of the card reader device when the antenna of the card reader device is in close proximity to the card reader device and to deactivate the low-power card detection mode of the card reader device, and the communication antenna coil is used to communicate with the card reader device in the full-power card detection mode of the card reader device. In related technologies, the technical problem that NFC debit devices cannot complete settlements under conditions of no power supply can be solved, and by waking up a card reader device in low-power card detection mode with a bare wire coil wake-up tuning coil provided on the passive short-range communication device, and then performing full-power communication with this card reader device via the communication antenna coil, settlements can be completed under conditions of no power supply, while simultaneously improving the coupling effect to the card reader device in low-power mode.

[0051] In one exemplary embodiment, the wake-up tuning coil comprises a first wake-up tuning coil.

[0052] The first wake-up tuning coil and the communication antenna coil are coplane or their planes are parallel to each other, and the induced magnetic fields within the coils overlap.

[0053] Preferably, the first wake-up tuning coil and the communication antenna coil may be arranged in the passive short-range communication device in an embedded parallel swivel configuration.

[0054] According to the above embodiment, by aligning the first wake-up tuning coil and the communication antenna coil on the same plane, or by aligning the planes in which they are located parallel to each other, and by overlapping the induced magnetic fields within the coils, this passive short-range communication device can communicate with the card reader device immediately after waking it up, while simultaneously achieving a space-saving technical effect.

[0055] In one exemplary embodiment, the position of the wake-up tuning coil is determined based on the position of the NFC antenna included in the card reader device. In practice, the passive near-field communication device may be, for example, an NFC tag card (hereinafter simply referred to as an NFC card), and a mobile phone may be used as the card reader device. Therefore, the position of the wake-up tuning coil in the NFC card can be determined according to the position of the NFC antenna on the mobile phone. According to user habits, when a user reads the NFC card through the mobile phone, they usually bring the top of the mobile phone close to the NFC card. According to this habit, for mobile phones where the NFC antenna is located on the top of the phone, the wake-up tuning coil in the NFC card may be located on the top of the NFC card, and for mobile phones where the NFC antenna is located in the middle of the phone, the wake-up tuning coil in the NFC card may be located in the middle or lower half of the NFC card. To ensure good card reading performance for both of the above two mobile phone models, one wake-up synchronization coil may be provided on the upper side of the NFC card, and another wake-up synchronization coil may be provided on the middle or lower half of the NFC card.

[0056] As described above, by providing a wake-up tuning coil in the NFC card, when a user brings their mobile phone close to the NFC card, the position of the wake-up tuning coil in the NFC card and the position of the NFC antenna in the mobile phone are widely aligned. This makes it easier for the NFC card to receive the LPCD mode electromagnetic signal transmitted from the mobile phone, and also makes it easier for the card reader device to receive the electromagnetic signal transmitted by the NFC card based on this received electromagnetic signal. Thus, the probability of the card reader device converting to normal card detection mode is increased, that is, the success rate of NFC recognition is improved.

[0057] In one exemplary embodiment, the first wake-up tuning coil is located in the middle or lower half of the passive short-range communication device to couple with the antenna in the middle or lower half of the card reader device.

[0058] For example, the card reader device described above may be a mobile phone running a mainstream Android system, and this type of card reader device typically has its antenna located in the middle or lower half of the device.

[0059] According to the above embodiment, the first wake-up tuning coil is positioned in the middle or lower half of the passive short-range communication device and used to couple with the antenna in the middle or lower half of the card reader device, thereby improving the convenience of coupling this passive short-range communication device with a mainstream card reader device.

[0060] In one exemplary embodiment, the shape of the first wake-up tuning coil is rectangular or oblate and is used to couple with a rectangular or oblate antenna of the card reader device.

[0061] For example, the card reader device may be an Android mobile phone, and this type of card reader device typically has a rectangular or oblate antenna.

[0062] According to the above embodiment, by making the shape of the first wake-up tuning coil rectangular or oblate, it is coupled with the rectangular or oblate antenna of the card reader device, thereby improving the coupling effect between this passive short-range communication device and the mainstream card reader device.

[0063] In one exemplary embodiment, the wake-up tuning coil comprises a second wake-up tuning coil.

[0064] The second wake-up tuning coil described above is located above the passive short-range communication device and is used to couple with the upper antenna of the card reader device.

[0065] For example, the card reader device described above may be an iOS mobile phone, and this type of card reader device typically has an antenna located on the top of the device.

[0066] According to the above embodiment, the second wake-up tuning coil is positioned above the passive short-range communication device and used to couple with the upper antenna of the card reader device, thereby improving the convenience of coupling this passive short-range communication device with an iOS system type card reader device.

[0067] In one exemplary embodiment, the shape of the second wake-up tuning coil is striped and is used to couple with the upper striped antenna of the card reader device.

[0068] For example, the card reader device described above may be an iOS mobile phone, and this type of card reader device typically has its antenna arranged in a stripe pattern.

[0069] According to the above embodiment, the shape of the first wake-up tuning coil is made into a stripe shape and used to couple with the stripe-shaped antenna of the card reader device, thereby improving the coupling effect between this passive short-range communication device and the iOS system type card reader device.

[0070] Figure 2 is a schematic diagram of the coil structure of a passive short-range communication device of one arbitrary embodiment of the present disclosure, comprising a first wake-up tuning coil 201, a second wake-up tuning coil 202, and a communication antenna coil 203, as shown in Figure 2.

[0071] In this configuration, the rectangular second wake-up tuning coil 202 and the communication antenna coil 203 are embedded in the lower half of the passive short-range communication device and arranged in a parallel spiral. The striped first wake-up tuning coil 201 is located on the upper side of the passive short-range communication device.

[0072] Another embodiment of the embodiments of the present disclosure further provides a passive short-range communication method, Figure 3 being a flowchart of a passive short-range communication method according to an embodiment of the present disclosure, which includes the following steps.

[0073] Step 302: Receive the low-power card detection carrier of the card reader device via a wake-up tuning coil whose resonant point is the same as the carrier frequency band of the card reader device.

[0074] This bare wire coil may be an LC oscillator circuit not connected to an NFC chip. The card reader device may be a mobile phone with NFC functionality.

[0075] Step 304: The wake-up tuning coil generates a wake-up inductive magnetic field to deactivate the low-power card detection mode of the card reader device, based on the low-power card detection carrier.

[0076] The resonance point of the wake-up tuning coil and the carrier frequency band of the card reader device may be 13.56 MHz. After the low-power card detection mode of the card reader device is deactivated, it can enter full-power card detection mode.

[0077] Step 306: The full-power card detection carrier of the card reader device is received via a communication antenna coil connected to the NFC chip and tuned to the carrier frequency band of the card reader device.

[0078] The card reader device may wake up the full-power card detection mode by approaching the wake-up tuning coil in low-power card detection mode and inducing a magnetic field in the wake-up tuning coil.

[0079] Step 308: The communication antenna coil generates a communication induction magnetic field in response to a full-power card detection carrier and communicates with the card reader device based on the communication induction magnetic field.

[0080] This communication antenna coil may generate load modulation via the NFC chip and complete communication with the card reader device.

[0081] Specifically, the communication antenna coil provides a full-power card detection carrier signal, including a read command, to the NFC chip. The NFC chip responds to this read command by acquiring the data stored in the NFC chip and applying load modulation to the communication antenna coil based on this data, causing the communication antenna coil to generate a communication-induced magnetic field. The card reader device receives this data by receiving this communication-induced magnetic field. Also, referring to Figure 2, after the card reader device enters full-power card detection mode, if the card reader device is an iOS system mobile phone, a signal can be transmitted between the antenna of the card reader device and the communication antenna coil 203 via the first wake-up tuning coil 201, thereby improving the communication effect.

[0082] Steps 302 to 308 above allow the low-power card detection carrier of the card reader device to be received via a wake-up tuning coil whose resonance point is the same as the carrier frequency band of the card reader device. When the wake-up tuning coil receives the low-power card detection carrier of the card reader device, it generates a wake-up inductive magnetic field to deactivate the low-power card detection mode of the card reader device. The full-power card detection carrier of the card reader device is received via a communication antenna coil connected to the NFC chip and tuned to the carrier frequency band of the card reader device. When the communication antenna coil receives the full-power card detection carrier of the card reader device, it generates a communication inductive magnetic field and communicates with the card reader device based on the communication inductive magnetic field. In related technologies, the technical challenge of NFC withdrawal devices being less able to complete payments under conditions without power supply can be solved. By waking up a card reader device in low-power card detection mode using a wake-up tuning coil of a bare wire coil provided in the passive short-range communication device, and then performing full-power communication with this card reader device via a communication antenna coil, payment completion can be achieved under conditions without power supply, while simultaneously improving the coupling effect with the low-power card reader device.

[0083] In one exemplary embodiment, the step of receiving a low-power card detection carrier of the card reader device via a wake-up tuning coil is: The step includes receiving a low-power card detection carrier of the card reader device via a first wake-up tuning coil, which is coplane with or located on the above-mentioned communication antenna coil, with the planes of the coils parallel to each other, and inductive magnetic fields within the coil overlapping.

[0084] Preferably, the first wake-up tuning coil and the communication antenna coil may be arranged in the passive short-range communication device in an embedded parallel swivel configuration.

[0085] According to the above embodiment, by aligning the first wake-up tuning coil and the communication antenna coil on the same plane or aligning the planes between them parallel to each other, and overlapping the induced magnetic fields within the coils, this passive short-range communication device can communicate with the card reader device immediately after waking it up, while simultaneously achieving a space-saving technical effect.

[0086] In one exemplary embodiment, the first wake-up tuning coil is located in the middle or lower half of a passive short-range communication device and is used to couple with an antenna in the middle or lower half of a card reader device.

[0087] For example, the card reader device described above may be a mobile phone running a mainstream Android system, and this type of card reader device typically has its antenna located in the middle or lower half of the device.

[0092] In one exemplary embodiment, the step of receiving a low-power card detection carrier of the card reader device via a wake-up tuning coil is: The process includes receiving a low-power card detection carrier transmitted from the upper antenna of the card reader device via a second wake-up tuning coil located above the passive short-range communication device.

[0093] For example, the card reader device described above may be an iOS mobile phone, and this type of card reader device typically has an antenna located on the top of the device.

[0094] According to the above embodiment, the convenience of connecting the passive short-range communication device to an iOS system type card reader device is improved by positioning the second wake-up tuning coil on the upper side of the passive short-range communication device in order to connect it to the upper antenna of the card reader device.
