[0030] Fast payment is a payment method that can complete the transfer of funds in a short time. Compared with traditional payment methods, it greatly shortens the payment processing time and enables transactions to be completed in real time. Fast payment can complete the transfer of funds from the payer's account to the payee's account within a few seconds to a few minutes, providing users with an efficient and convenient payment experience.

[0031] Currently, there are two payment methods: scanning a code box and tapping to scan a code; however, both payment methods require flipping the mobile device twice, which makes the payment efficiency low; and the same payment device cannot support multiple payment methods.

[0032] The technical solution provided by the present application is intended to solve the above technical problems of the prior art. In this embodiment, in the payment method and payment device provided by the present application, when the NFC tag detects the presence of a terminal device in the sensing area, the payment program in the terminal device is called up to apply for a payment code; the payment code is written into the NFC tag in a dynamic write-back manner to obtain an NFC tag containing the payment code information; the payment code information in the NFC tag is sent to the payee management information system through the external connection module to make payment. By combining the terminal device with NFC touch, this solution further shortens the operation process and improves payment efficiency.

[0033] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0034] Embodiment 1

[0035] Figure 1 A payment method provided for this application Figure 1 ,like Figure 1 As shown, it is applied to a fast payment device, the payment device includes an NFC tag and an external connection module; the method includes:

[0036] S101, when the NFC tag detects that there is a terminal device in the sensing area, the payment program in the terminal device is called up to apply for a payment code.

[0037] S102, writing the payment code into the NFC tag by dynamically writing back to obtain an NFC tag containing the payment code information.

[0038] S103, sending the payment code information in the NFC tag to the payee management information system through the external connection module to make payment.

[0039] Among them, dynamic write-back is not pre-set and unchanging, but writes the payment code payment data back to a storage medium based on the user's actual application and the payment scenario at the time. The storage medium is an NFC tag or other smart tag.

[0040] In actual application scenarios, when a user chooses the NFC payment method, the NFC tag calls up the payment program in the user's mobile phone. The payment program applies for a payment code and writes the payment code into the NFC tag in a dynamic write-back manner to obtain an NFC tag containing the payment code information. Using the NFC tag as a medium, the external connection module sends the payment code information in the NFC tag to the payee's management information system for payment. The payee's management information system (MIS) is a system used to process payment transactions and manage related business processes in the payment application scenario.

[0041] The external connection module can connect to the payment recipient's management information system via wired or wireless (Wi-Fi\Bluetooth).

[0042] In addition, an indicator light may be provided on the payment device, using lights of different colors to indicate different states, for example, a red light indicates that the payment is being processed, and a green light indicates that the payment has been processed.

[0043] In essence, the core of the payment code is composed of a series of character information; whether it is a QR code or a barcode, after being decoded, they can be regarded as a string of characters containing key payment information. Therefore, in this example, the payment program of the terminal device is called up through the NFC tag, and the payment program applies for a payment code, which is directly written into the NFC tag by dynamic write-back; then the external connection module sends the payment code information in the NFC tag to the payee management information system, and the payee management system will make payment according to the key payment information in the payment code information. There is no need to generate a QR code payment code based on the payment code; the payment code in this form is scanned and read by the camera, and the payment code information for generation is parsed, and the payment is made according to the key payment information in the payment code information. By directly writing the payment code back dynamically, there is no need to flip the mobile phone to scan the QR code payment code, which shortens the operation process and improves payment efficiency.

[0044] Figure 2 A payment method provided for this application Figure 2 ,like Figure 2 As shown, in some examples, the payment device further includes a camera; the method further includes:

[0045] S201, if the payment fails, the payment page of the terminal device is called up through the NFC tag, and a sensing signal is generated and sent to the external connection module, so that the external connection module sends a collection instruction to the camera according to the sensing signal.

[0046] S202, reading the payment QR code obtained by scanning the payment page in response to the collection instruction by the camera, and obtaining payment code information; wherein the payment QR code is obtained by encoding the payment code.

[0047] S203, sending the payment code information to the payee management information system through the external connection module to make payment.

[0048] The payment QR code is obtained by encoding the payment code according to specific QR code encoding rules and converting it into a black and white dot matrix pattern.

[0049] In this example, the payment QR code is the graphical QR code or barcode we see; when making a payment, the camera performs optical reading and converts the graphic information into character information.

[0050] Preferably, both the NFC payment method and the camera scanning payment method can be implemented in the payment device. When one of the payment methods fails, the other payment method is executed. For example, in the NFC payment method, when the payment fails, the payment page can be called up, the payment QR code can be generated, and the payment can be made by scanning the camera. This payment device can support multiple payment methods, improve the payment success rate; at the same time, it solves the problem of lengthy operation procedures in the existing payment process and improves payment efficiency.

[0051] In some examples, the camera is disposed above the sensing area to capture images of the sensing area.

[0052] The camera module is located above the sensing area, and the camera can directly scan the payment QR code displayed on the user's mobile phone. In actual application, after the user places the mobile phone in the sensing area, the NFC tag calls up the payment page of the mobile phone and displays a payment QR code. At this time, the camera can directly scan the payment QR code, so there is no need to flip the mobile phone for scanning, which improves payment efficiency.

[0053] In some examples, when no data collection instruction is received, the camera is switched to a standby mode.

[0054] In actual applications, the switch control based on the sensing signal of the NFC tag will set the working mode and standby mode. Specifically, the camera will be in working mode only when receiving the data collection instruction; when no data collection instruction is received, it is in standby mode, at which time the camera stops working, reducing the power consumption level of the device and increasing the standby time of the device.

[0055] In some examples, after the payment is successful, the payment code information contained in the NFC tag is cleared.

[0056] After the payment is successful, the payment code information contained in the NFC tag is cleared. The purpose is to prevent information leakage and avoid conflicts and confusion with newly written information during the subsequent reading and use of NFC tag information. By clearing the old information, it can be ensured that each time the NFC tag is used, the data it provides is clear and unambiguous.

[0057] In some examples, before invoking the payment program in the terminal device, the method further includes:

[0058] Detect whether the terminal device has the terminal payment function turned on. If so, perform terminal payment.

[0059] Initiate payment procedures, including:

[0060] If the terminal device does not have the terminal payment function enabled or the terminal payment fails, the payment program in the terminal device is called up.

[0061] Among them, terminal payment is for example mobile phone Pay payment; mobile phone Pay payment (such as the common Apple Pay, Samsung Pay, Huawei Wallet, etc.) is a payment method that uses mobile devices (mobile phones) as payment tools. It uses near-field communication technology (NFC) or other secure communication technologies to store card information such as bank cards, credit cards, transportation cards, membership cards, etc. in the mobile phone's secure chip or secure software environment, and simulates physical cards for transactions when paying.

[0062] Combine mobile phone Pay payment, NFC touch and code scanning (being scanned) processes; Figure 3 A payment device, such as Figure 3 As shown in the figure, the NFC tag is responsible for calling the payment program and payment page, the NFC card reader is responsible for reading the mobile phone Pay simulated card, the external connection module is responsible for receiving payment information and connecting to the payee management information system, and the camera module is used to scan the QR code information. This payment device can support NFC payment and camera scanning payment.

[0063] In some examples, if the payment is successful, the order payment information is obtained and a payment success page is displayed.

[0064] Among them, this page displays detailed information such as the payment amount, payment time, and payee, so that users can clearly know that their money has been successfully paid and the specific details of the payment. For merchants, the payment success page can also serve as one of the vouchers for the completion of the transaction.

[0065] A payment method provided by an embodiment of the present application, in the payment method and payment device provided by the present application, when the NFC tag detects the presence of a terminal device in the sensing area, the payment program in the terminal device is called up to apply for a payment code; the payment code is written into the NFC tag in a dynamic write-back manner to obtain an NFC tag containing the payment code information; the payment code information in the NFC tag is sent to the payee management information system through an external connection module to make payment. This solution further shortens the operation process and improves payment efficiency by combining the terminal device with NFC touch.

[0070] The processing module 11 is also used to send the payment code information in the NFC tag to the payee management information system through the external connection module for payment.

[0071] Among them, dynamic write-back is not pre-set and unchanging, but writes the payment code payment data back to a storage medium based on the user's actual application and the payment scenario at the time. The storage medium is an NFC tag or other smart tag.

[0072] In actual application scenarios, when a user chooses the NFC payment method, the NFC tag calls up the payment program in the user's mobile phone. The payment program applies for a payment code and writes the payment code into the NFC tag using dynamic write-back to obtain an NFC tag containing the payment code information.

[0075] In addition, an indicator light may be provided on the payment device, using lights of different colors to indicate different states, for example, a red light indicates that the payment is being processed, and a green light indicates that the payment has been processed.

[0076] In essence, the core of the payment code is composed of a series of character information; whether it is a QR code or a barcode, after being decoded, they can be regarded as a string of characters containing key payment information. Therefore, in this example, the payment program of the terminal device is called up through the NFC tag, and the payment program applies for a payment code, which is directly written into the NFC tag by dynamic write-back; then the external connection module sends the payment code information in the NFC tag to the payee management information system, and the payee management system will make payment according to the key payment information in the payment code information.
