Description

Technical Field

[0001] This disclosure relates to the field of payment terminal control technology, specifically to a multi-mode payment terminal control method, device, equipment, medium, and program product. Background Technology

[0002] Currently, there is an integrated payment terminal on the market that combines QR code payment and NFC card payment functions, such as... Figure 1 The NFC scanning box shown integrates NFC card payment functionality into a scanning box with QR code payment capabilities. The NFC induction coil and the scanning window overlap. A common problem with this type of integrated payment terminal is that when a user scans a QR code to pay with their mobile phone, and the phone is close to the scanning box, the NFC card payment module directly activates the phone's NFC payment application. This causes interference between QR code payment and NFC card payment, reducing the user's payment success rate and impacting the payment experience.

[0003] To address the aforementioned issues, the current solution is to weaken the magnetic field strength of the NFC induction coil. This ensures that the NFC payment application is only activated when the user's phone is very close to the scanning window, thus reducing the probability of accidental activation. While this solution reduces the likelihood of accidental activation, it doesn't fundamentally solve the problem of interference between QR code payments and NFC card payments. Furthermore, weakening the NFC induction coil's magnetic field reduces card-swiping sensitivity during NFC card payments, negatively impacting the user's payment experience. Summary of the Invention

[0030] Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings to enable those skilled in the art to readily implement them. Furthermore, for clarity, portions unrelated to the description of the exemplary embodiments have been omitted from the drawings.

[0031] In embodiments disclosed herein, it should be understood that terms such as “comprising” or “having” are intended to indicate the presence of features, numbers, steps, behaviors, components, portions or combinations thereof disclosed herein, and are not intended to exclude the possibility that one or more other features, numbers, steps, behaviors, components, portions or combinations thereof are present or added.

[0032] It should also be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings and examples.

[0033] As mentioned above, there is currently an integrated payment terminal on the market that combines QR code payment and NFC card payment functions, such as... Figure 1 The NFC scanning box shown integrates NFC card payment functionality into a scanning box with QR code payment capabilities. The NFC induction coil and the scanning window overlap. A common problem with this type of integrated payment terminal is that when a user scans a QR code to pay with their mobile phone, the NFC card payment module directly wakes up the phone's NFC payment application when the phone is close to the scanning box. This causes interference between QR code payment and NFC card payment, reducing the success rate of payments and impacting the user's payment experience. Current solutions to this problem involve weakening the magnetic field strength of the NFC induction coil. This ensures that the NFC payment application is only activated when the user's phone is very close to the scanning window, thus reducing the probability of accidental activation. While this solution reduces the probability of accidental activation, it doesn't fundamentally solve the problem of interference between QR code payment and NFC card payment. Furthermore, weakening the magnetic field strength of the NFC induction coil reduces the card-swiping sensitivity during NFC card payments, further affecting the user's payment experience.

[0034] Based on the above, and to address the problems existing in the prior art, this disclosure proposes a multi-mode payment terminal control method. This method first disables the NFC payment mode and uses the coarse scanning function of the scanning device to determine if a QR code exists. If a QR code exists, the scanning payment process continues; otherwise, the NFC payment mode is enabled, and the NFC payment process begins. This technical solution ensures a higher payment success rate, improves payment efficiency, and enhances the user's payment experience by switching between NFC and QR code payment modes. Simultaneously, the switching between the first and second modes of the scanning device saves energy.

[0035] Figure 2 A flowchart of a multi-mode payment terminal control method according to an embodiment of the present disclosure is shown, such as... Figure 2As shown, the multi-mode payment terminal control method includes the following steps S201-S204:

[0036] In step S201, the NFC payment mode is turned off and the QR code payment mode is turned on;

[0037] In step S202, in response to receiving the payment initiation command, the first mode of the scanning device is started to perform a coarse scan of the QR code to determine whether a QR code exists within a first preset distance;

[0038] In step S203, when the scanning device determines that a QR code exists, it starts the second mode of the scanning device to perform a detailed scan of the QR code and enters the QR code payment process.

[0039] In step S204, when the scanning device determines that there is no QR code, it activates the NFC payment mode and enters the NFC payment process.

[0040] In one embodiment of this disclosure, the multi-mode payment terminal control method can be applied to terminal computers, computing devices, electronic devices, servers, service clusters, etc., that can perform multi-mode payment terminal control.

[0041] In one embodiment of this disclosure, the multi-mode payment terminal supports at least a QR code payment mode and an NFC payment mode. The QR code payment mode refers to a payment mode in which a QR code is scanned using a scanning device to obtain the corresponding payment information, and the payment process is completed based on the obtained payment information. The NFC payment mode refers to a payment mode in which a card swipe payment is realized using near-field communication technology.

[0042] In one embodiment of this disclosure, the control of enabling or disabling the NFC payment mode can be achieved by controlling the magnetic field of the NFC induction coil. For example, if you want to disable the NFC payment mode, you can disable the magnetic field of the NFC induction coil; if you want to enable the NFC payment mode, you can enable the magnetic field of the NFC induction coil.

[0043] In one embodiment of this disclosure, the control of enabling or disabling the QR code payment mode can be achieved by controlling the QR code scanning device and its image recognition function. For example, if you want to disable the QR code payment mode, you can disable the QR code scanning device and its image recognition function; if you want to enable the QR code payment mode, you can enable the QR code scanning device and its image recognition function. The QR code scanning device can be, for example, an electronic device that supports QR code scanning, such as a QR code scanning camera.

[0044] In one embodiment of this disclosure, the payment initiation command refers to a command to begin the payment process.

[0045] In one embodiment of this disclosure, the first mode of the scanning device refers to a mode that supports coarse scanning of QR codes. In this embodiment, activating the first mode of the scanning device is used to determine whether a QR code exists at a position within a first preset distance from the scanning device. The first mode of the scanning device can also be called a low-precision scanning mode. In this mode, since the scanning device only needs to perform a coarse scan within the first preset distance and roughly focus on the QR code without precise focusing or recognizing the information carried by the QR code, the scanning device is in a low-power state in the first mode.

[0046] The first preset distance refers to the distance used only to determine whether a QR code exists within a preset range of the scanning device. The first preset distance can be set according to the parameters of the scanning device and the needs of actual application.

[0047] In one embodiment of this disclosure, the second mode of the scanning device refers to a mode that supports the scanning device to perform fine scanning of QR codes for QR code payment, which can also be called a high-precision scanning mode. In this mode, the scanning device needs to accurately focus on the QR code, judge the clarity of the QR code, and identify the information carried by the QR code, etc., to provide data support for QR code payment and ensure the success rate of QR code payment. Therefore, in the second mode, the scanning device is in a high-energy-consumption state.

[0048] In the above embodiments, a multi-mode payment terminal control method is proposed. This method, when the multi-mode payment terminal is activated, first disables the NFC payment mode, enabling only the QR code payment mode to avoid interference between the NFC payment mode and the QR code payment mode. Then, upon receiving a payment initiation command, the method first uses the coarse scanning function of the QR code scanner to determine if a QR code exists within a first preset distance. If it exists, the method initiates the fine scanning function to continue the QR code payment process. If not, the NFC payment mode is then activated, and the NFC payment process begins. After the NFC payment process is completed, the NFC payment mode is disabled to ensure that the NFC payment mode is disabled and the QR code payment mode is enabled for the next payment attempt. This technical solution ensures a higher payment success rate, improves payment efficiency, and enhances the user's payment experience by switching between the NFC payment mode and the QR code payment mode. Simultaneously, the switching between the first and second modes of the QR code scanner saves energy consumption.

[0049] In one embodiment of this disclosure, the step S202, which involves activating the first mode of the scanning device to perform a coarse scan of the QR code and determining whether a QR code exists within a first preset distance, may include the following steps:

[0050] The first mode of the scanning device is activated to perform a coarse scan of the QR code and determine whether QR code features exist within a first preset distance.

[0051] When it is determined that there are QR code features within a first preset distance, it is determined that there are QR codes within the first preset distance.

[0052] In this embodiment, the presence of a QR code within a first preset distance is determined by judging whether QR code features exist within that first preset distance. That is, when a payment initiation command is received, the first mode of the scanning device is first activated to perform a coarse scan of the QR code within the first preset distance to determine whether QR code features exist within the first preset distance. If QR code features exist within the first preset distance, then it can be determined that a QR code exists within the first preset distance.

[0053] In one embodiment of this disclosure, the QR code feature can be a QR code positioning feature. There can be multiple QR code positioning features, each with a preset size and located at a preset position, such as a positioning mark in the QR code. When the QR code positioning feature is a QR code positioning mark, the QR code positioning feature consists of three positioning squares with a preset size, located at the upper left, lower left, and upper right corners of the QR code, respectively.

[0054] In this embodiment, the step of determining whether there are QR code features within the first preset distance may include the following steps:

[0055] Determine whether there are a preset number of QR code positioning features of a preset size within a first preset distance;

[0056] When it is determined that there are a preset number of QR code positioning features with a preset size within a first preset distance, it is determined whether the relative positions between the QR code positioning features meet the preset requirements.

[0057] When it is determined that the relative positions between the QR code positioning features meet the preset requirements, it is determined that there are QR code features within the first preset distance.

[0058] Taking the QR code feature as a positioning marker as an example, in this embodiment, when determining whether a QR code feature exists within a first preset distance, it is first determined whether there are three positioning blocks of a preset size within the first preset distance. If so, it is then determined whether these three positioning blocks satisfy the relative positional relationship of the upper left, lower left, and upper right corners. If so, it indicates that a QR code feature exists within the first preset distance. How to determine whether the three positioning blocks satisfy the relative positional relationship of the upper left, lower left, and upper right corners is a technique that should be mastered by those skilled in the art, and this disclosure will not describe it in detail.

[0059] Furthermore, in one embodiment of this disclosure, if no QR code feature is detected within a preset time period, it can be determined that there is no QR code within the first preset distance.

[0060] In one embodiment of this disclosure, step S203, that is, before starting the second mode of the scanning device to perform fine scanning of the QR code, may further include the following steps:

[0061] Detect the distance between the scanning device and the QR code;

[0062] When the distance between the scanning device and the QR code is less than or equal to the second preset distance, the second mode of the scanning device is activated to perform fine scanning of the QR code.

[0063] In this embodiment, in order to reduce the energy consumption of the scanning device and improve the recognition efficiency and accuracy of the QR code, before starting the second mode of the scanning device to perform fine scanning of the QR code, the distance between the scanning device and the QR code is first detected. Only when the distance between the scanning device and the QR code is less than or equal to a second preset distance will the second mode of the scanning device be started to perform fine scanning of the QR code.

[0064] The second preset distance is less than the first preset distance. Similar to the first preset distance, the second preset distance can also be set according to the parameters of the scanning device and the needs of actual application.

[0065] In one embodiment of this disclosure, step S203, namely, activating the second mode of the scanning device to perform fine scanning of the QR code, may include the following steps:

[0066] Start the second mode of the scanning device to scan the QR code and obtain the QR code image;

[0067] Detect the image clarity of the QR code image;

[0068] When the image clarity of the QR code image meets the preset clarity requirements, the QR code image is scanned in detail to obtain the information carried by the QR code.

[0069] In this embodiment, in order to further reduce the energy consumption of the scanning device and improve the recognition efficiency and accuracy of the QR code, when the second mode of the scanning device is activated for fine scanning of the QR code, the second mode of the scanning device is first used to scan the QR code to obtain a QR code image. Then, the image clarity of the QR code image is detected. When the image clarity of the QR code image meets the preset clarity requirements, the QR code image is then finely scanned to identify the payment information and other information carried by the QR code.

[0070] The preset clarity requirement can be set according to payment requirements and the needs of actual applications.

[0071] Figure 3 This diagram illustrates the overall flowchart of a multi-mode payment terminal control method according to an embodiment of the present disclosure, as follows: Figure 3 As shown, when the multi-mode payment terminal is turned on, the NFC payment mode is turned off and the QR code payment mode is turned on. Upon receiving a payment initiation command, the first mode of the scanning device is activated to perform a coarse scan of the QR code to determine whether QR code features exist within a first preset distance. If they exist, the existence of the QR code is confirmed. When the distance between the scanning device and the QR code is less than or equal to a second preset distance, the second mode of the scanning device is activated to perform a fine scan of the QR code, identify the information carried by the QR code, and enter the QR code payment process. If no QR code features are detected within a preset time period, it is confirmed that no QR code exists, the NFC payment mode is activated, and the NFC payment process is entered. After the NFC payment process is completed, the NFC payment mode is turned off to ensure that the NFC payment mode is turned off and the QR code payment mode is turned on for the next payment.

For example, if you want to disable the NFC payment mode, you can disable the magnetic field of the NFC induction coil; if you want to enable the NFC payment mode, you can enable the magnetic field of the NFC induction coil.

[0081] In one embodiment of this disclosure, the control of enabling or disabling the QR code payment mode can be achieved by controlling the QR code scanning device and its image recognition function. For example, if you want to disable the QR code payment mode, you can disable the QR code scanning device and its image recognition function; if you want to enable the QR code payment mode, you can enable the QR code scanning device and its image recognition function. The QR code scanning device can be, for example, an electronic device that supports QR code scanning, such as a QR code scanning camera.

In this mode, since the scanning device only needs to perform a coarse scan within the first preset distance and roughly focus on the QR code without precise focusing or recognizing the information carried by the QR code, the scanning device is in a low-power state in the first mode.

[0084] The first preset distance refers to the distance used only to determine whether a QR code exists within a preset range of the scanning device. The first preset distance can be set according to the parameters of the scanning device and the needs of actual application.

In this mode, the scanning device needs to accurately focus on the QR code, judge the clarity of the QR code, and identify the information carried by the QR code, etc., to provide data support for QR code payment and ensure the success rate of QR code payment. Therefore, in the second mode, the scanning device is in a high-energy-consumption state.

[0086] In the above embodiments, a multi-mode payment terminal control device is proposed. When the multi-mode payment terminal is activated, this device can first disable the NFC payment mode and only enable the QR code payment mode to avoid interference between the NFC payment mode and the QR code payment mode. Then, upon receiving a payment initiation command, the device first uses the coarse scanning function of the QR code scanner to determine whether a QR code exists within a first preset distance. If it exists, the device initiates the fine scanning function to continue the QR code payment process.
