detailed description

Exemplary embodiments will be described in detail here, examples of which are shown in the drawings. When referring to the drawings below, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this specification. Rather, they are merely examples of devices and methods consistent with some aspects of this specification as detailed in the appended claims.

The terminology used in this specification is for the purpose of describing particular embodiments only, and is not intended to limit this specification. The singular forms "a", "said" and "the" used in this specification and the appended claims are also intended to include most forms unless the context clearly indicates other meanings. It should also be understood that the term "and / or" as used herein refers to and includes any or all possible combinations of one or more associated listed items.

It should be understood that although the terms first, second, third, etc. may be used to describe various information in this specification, the information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this specification, the first information may also be referred to as second information, and similarly, the second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when" or "when" or "in response to a determination".

The instantaneous or short-term described in this specification is relative to the duration of the entire payment process. Generally, the duration of less than the threshold can be called the instantaneous or short-term, for example, the payment with a payment duration of less than 5 seconds Instant payment or short-term payment.

The following uses the mobile payment application in public transportation as an example to illustrate the instant or short-term payment scenario. When taking a bus, passengers need to pay the bus ride fee. However, due to the large number of passengers on board and the bus driver needs to focus on driving, the scan code payment method is not applicable. For this reason, NFC (Near Field Communication) payment or anti-scan code payment technology has been introduced in related technologies.

The reverse scan code payment technology is the opposite of scan code payment. Scan code payment is a QR code provided by the payee and scanned by the payer; while scan code payment is a QR code produced by the payer and scanned by the payee . Among them, anti-scanning code payment generally requires the payee to be equipped with a scanning terminal. When in use, the payer can move the payment QR code displayed on the mobile terminal close to the code scanning terminal for the code scanning terminal to automatically scan the code; the payment amount is also set by the code scanning terminal.

As shown in FIG. 1, it is a schematic structural diagram of a mobile payment system provided by the present specification. The system may include a mobile terminal 10 and a payment collection device 20; ) Module 11, the RCC module 11 may specifically include a Bluetooth communication (Bluetooth Low Energy, BLE) module 111, a 2.4G communication module 112, an alternating magnetic field module 113, and a microcontroller unit (MCU) 114;

The alternating magnetic field module 113 is used to identify the device information and 2.4G communication link parameters of the payment device 20 transmitted by the payment device 20 that supports limited-area communication through the alternating magnetic field;

The 2.4G communication module 112 is used to establish a 2.4G communication link with the payment collection device 20;

The Bluetooth communication module 111 is used to establish a Bluetooth communication link with the mobile terminal 10;

The micro control unit 114 is configured to transfer the device information 20 to the payment application installed on the mobile terminal 10 based on the Bluetooth communication link; and pass the payment code generated by the payment application according to the device information The 2.4G communication link is sent to the payment device 20, so that the payment device 20 completes the payment transaction corresponding to the payment code through the anti-scanning code payment link.

As shown in FIG. 1, the system may further include a payment operation server 30 for receiving and processing the payment transaction request initiated by the payment collection device 20 after the anti-scanning payment code. Specifically, an anti-scanning payment link may be established between the payment collection device 20 and the payment operation server 30 for executing a payment transaction request of the payment collection device 20.

The mobile terminal 10 may include mobile devices such as smart phones, smart watches, and smart bracelets.

Among them, the name of the payment device 20 may be different in different scenarios. For example, in a shopping place, the payment device 20 may refer to a POS (Point of sales) machine; on a bus, the payment device 20 20 can refer to a smart bus card swipe machine; in a subway scenario, the collection device 20 can be a subway gate (also called a wing gate); in short, no matter what the scenario, as long as it is a machine, device, etc. used for collection Can be called a collection device.

Among them, the restricted communication is a technology that uses 2.4G (some are also called 2.45G) combined with an alternating magnetic field to realize data communication.

The difference between the RCC and the foregoing NFC may include at least:

1. Different communication frequency bands. The communication frequency band of NFC is 13.56MHz; and the frequency band of RCC is 2.4G. The 2.4G is a general term, and its communication frequency band is generally between 2.400GHz and 2.4835GHz, and some include 2.45GHZ.

2. The communication distance is different. The communication distance of NFC is usually within 10 cm; and RCC can realize the control of multiple communication distance sections such as within 10 cm in close range, within 50 cm in medium range, and around 10 meters in long range.

3. The communication bandwidth is different. NFC communication bandwidth is between 106K-848K; and RCC is between 1M-8M, which is 10 times that of NFC; therefore, the response time of RCC is much shorter than NFC.

It is worth mentioning that RCC can be applied to the mobile phone SIM (Subscriber Identification Module) card to make an RCC-SIM card. The mobile terminal can have RCC communication capabilities after it is inserted into the RCC-SIM card. Similarly, it can also be applied to an SD card (Secure Digital Memory Card) to make an RCC-SD card, and the mobile terminal can have RCC communication capabilities when inserted into the RCC-SD card.

In an implementation manner: the aforementioned limited domain communication module may refer to an RCC-SUM card, that is, the mobile terminal is inserted with an RCC-SUM card, so that the mobile terminal can have RCC communication capabilities.

In another implementation manner: the aforementioned limited-area communication module may refer to a hardware module that has an RCC function alone, and the hardware module may be integrated on the main board of the mobile terminal, so that the mobile terminal can have RCC communication capabilities.

Similarly, the cash collection device needs to have an RCC module if it wants to have RCC capability; of course, because the cash collection device does not need to have all the communication capabilities of a mobile terminal, it may not have a Bluetooth module.

In summary, the mobile device can implement RCC communication with the RCC-supported payment device based on the RCC module, and the mobile device can finally transmit the payer to the payment device through RCC communication to realize payment. On the one hand, due to the high efficiency of RCC communication, the response time of each payment can be shortened; on the other hand, the user only needs to bring the mobile terminal close to the payment collection device, and does not need to perform many operations like scanning the code; therefore, this manual is used The provided embodiment can quickly complete the mobile payment, greatly reducing the payment time and improving the payment efficiency.

In the following, please refer to the schematic flow chart of a mobile payment method provided in this specification shown in FIG. 2.4G communication module, alternating magnetic field module and micro control unit, the method includes:

Step 210: The micro control unit recognizes the device information and 2.4G communication link parameters of the payment device transmitted by the payment device that supports limited-domain communication through the alternating magnetic field based on the alternating magnetic field module.

Step 220: The micro control unit sets the 2.4G communication module based on the 2.4G communication link parameters, so that the 2.4G communication module establishes a 2.4G communication link with the payment collection device;

Step 230: The micro control unit transfers the device information to the payment application installed on the mobile terminal based on the Bluetooth communication link established between the Bluetooth communication module and the mobile terminal, so that the payment application Generate a payment code according to the device information;

Step 240: The micro control unit receives the payment code returned by the payment application through the Bluetooth communication link based on the Bluetooth communication module;

Step 250: The micro control unit sends the payment code to the payment device through the 2.4G communication link, so that the payment device completes the payment code corresponding to the payment code through the reverse scan code payment link Payment transaction.

As mentioned earlier, limited-area communication can refer to a technology that uses 2.4G (some are also called 2.45G) in combination with alternating magnetic fields to achieve data communication.

The following is a description of a complete mobile payment transaction process.

When the user needs to make a mobile payment, the user can hold the mobile terminal (the mobile terminal integrated RCC module) close to a payment collection device that supports RCC transactions. Wherein, the payment collection device continuously sends its own device information and 2.4G communication link parameters through an alternating magnetic field. The device information may include a collection device number (usually the number is unique, one number corresponds to a unique device) and / or a location of the collection device, the location may be the current city, and may be specifically located Latitude and longitude.

When the mobile terminal is sufficiently close to the payment collection device, the MCU of the RCC module on the mobile terminal can recognize the device information and 2.4G communication link parameters sent by the payment collection device based on the alternating magnetic field module.

On the one hand, the MCU can set the 2.4G communication module according to the 2.4G communication link parameters; since the 2.4G communication link parameters are the parameters for establishing the 2.4G communication link agreed by the collection device, when the 2.4G communication After the module also sets the 2.4G communication link parameters, the 2.4G communication link with the payment device can be established.

On the other hand, the MCU may establish a Bluetooth communication link between the Bluetooth communication module and the mobile terminal, and pass the device information to the payment application installed on the mobile terminal, so that the payment application Generating a payment code according to the device information; and the MCU may receive the payment code returned by the payment application through the Bluetooth communication link based on the Bluetooth communication module. Wherein, the payment application generates a payment code according to the device information, which may specifically include:

Based on the payment code generation algorithm, the payment code is generated based on the device information, code factor and transaction timestamp. The transaction timestamp can generally refer to the current timestamp when the payment code is generated, provided by the payment application.

After the MCU receives the payment code, it can send the payment code to the collection device based on the previously established and maintained 2.4G communication link, so that the collection device completes the payment through the anti-scanning code payment link The payment transaction corresponding to the payment code.

The anti-scanning code payment link, as shown in FIG. 1, is a link established between the payment collection device and the payment operation server, and is used to execute a payment transaction request of the payment collection device. After receiving the payment code, the collection device can scan the payment code to obtain the account information of the payer, assemble the collection request after adding the information such as the amount to be collected, and send the collection request based on the anti-scanning code payment link To the payment operation server, the payment operation server completes the transaction according to the message in the payment request, for example, in the case of determining the payer account, the payee account and the payment amount, the payment amount is deducted from the payer account Funds, and inject the deducted funds into the recipient's account.

The following are examples of application scenarios that apply the mobile payment solution of this manual.

Can be applied in public transportation scenarios:

The payer may include a public transportation ride code. Specifically: when taking the bus, the bus ride code; when taking the subway, the subway ride code; when taking the light rail, the light rail ride code; when taking the high-speed rail, motor train and other train ride codes.

It can also be used in daily shopping scenarios:

For example, payment for shopping in stores, payment for unmanned vending machines (unmanned ticket vending machines, baby grab machines, food and beverage machines, self-service camera machines, etc.).

Please note that the above application scenarios are only a few examples, and it is not limited to be implemented in the above application scenarios; it should be understood that all mobile payment application scenarios can implement the mobile payment solution provided in this specification.

According to the mobile payment solution provided in this specification, the mobile device can implement RCC communication with the RCC-supported payment device based on the RCC module. The mobile device can finally transmit the payer to the payment device through RCC communication to realize payment. On the one hand, due to the high efficiency of RCC communication, the response time of each payment can be shortened; on the other hand, the user only needs to bring the mobile terminal close to the payment collection device, and does not need to perform many operations like scanning the code; therefore, this manual is used The provided embodiment can quickly complete the mobile payment, greatly reducing the payment time and improving the payment efficiency.

Since the payment application needs to intervene to generate the payment code during the implementation of the above embodiment, the payment application in the mobile terminal needs to be always open during the payment process. In general, the payment application permissions can be set in the operating system of the mobile terminal, such as keeping the payment application running in the background while the screen is off, or the payment application self-starting, etc .; so that the user can realize the movement of RCC communication in the screen off state Pay. However, in actual applications, the user may not set the permission to pay the application; or some security software may restrict the self-starting of the payment application and automatically close the payment application running in the background, etc., which will cause the mobile terminal to be unable to make mobile payment when the screen is turned off. For this reason, this specification also provides another mobile payment solution to solve the problem of smoothly performing mobile payment when the mobile terminal is off.

As shown in FIG. 3, it is a schematic structural diagram of a mobile payment system provided by the present specification. The system includes a mobile terminal 60 and a payment collection device 70; wherein, the mobile terminal 60 has a restricted domain communication module 61, and the restricted domain The communication module 61 specifically includes a 2.4G communication module 612, an alternating magnetic field module 613, and a micro control unit 611. The security chip (SecureElement, SE) 614 in the micro control unit 611 stores a payment code generation algorithm and a payment application Code factor

The alternating magnetic field module 613 is used to identify the device information and 2.4G communication link parameters of the payment receiving device 70 transmitted by the payment receiving device 70 supporting limited-domain communication through the alternating magnetic field;

The 2.4G communication module 612 is used to establish a 2.4G communication link with the payment collection device 70;

The micro control unit 611 is used to receive the transaction time stamp sent by the payment collection device 70 through the 2.4G communication link; Generate payment code;

The micro control unit 611 is further configured to send the payment code to the payment device 70 through the 2.4G communication link, so that the payment device 70 completes the payment through the reverse scan code payment link Payment transaction corresponding to the code.

As shown in FIG. 3, the system may further include a payment operation server 80 for receiving and processing the payment transaction request initiated by the payment collection device 80 after the anti-scanning payment code. Specifically, an anti-scanning payment link may be established between the payment collection device 70 and the payment operation server 80 for executing the payment transaction request of the payment collection device 80.

The mobile terminal 60 may include mobile devices such as smart phones, smart watches, and smart bracelets.

Among them, the name of the collection device 70 may be different in different scenarios. For example, in a shopping place, the collection device 70 may refer to a POS machine; on a bus, the collection device 70 may refer to smart Bus credit card machine; in a subway scenario, the collection device 70 can be a subway gate (also called a wing gate); in short, no matter what the scenario, as long as it is a machine or device used to collect money, it can be called a collection device.

The RCC technology in this embodiment is the same as that in the foregoing embodiment, and details will not be repeated here.

In this embodiment, the mobile device may implement RCC communication with the RCC-enabled payment collection device based on the RCC module. The mobile device may finally transmit the payer to the payment collection device through RCC communication to realize payment. On the one hand, due to the high efficiency of RCC communication, the response time of each payment can be shortened; on the other hand, the user only needs to bring the mobile terminal close to the payment collection device, and does not need to perform many operations like scanning the code; therefore, this manual is used The provided embodiment can quickly complete mobile payment, greatly reducing the payment time and improving the payment efficiency; on the other hand, since the operation of the RCC module is not affected by the mobile terminal, as long as the mobile terminal is powered, the payment code can be generated through the security chip in the RCC module Therefore, mobile payment for RCC communication can be realized even when the mobile terminal is off.

The following refers to the schematic flowchart of a mobile payment method provided in this specification shown in FIG. 4, the method is applied to a mobile terminal, the mobile terminal integrates a limited domain communication module, and the limited domain communication module includes a 2.4G communication module , An alternating magnetic field module, a payment code generation module and a micro control unit, the security chip in the micro control unit stores a payment code generation algorithm and a code factor provided by a payment application, the method includes:

Step 310: The micro control unit recognizes the device information and 2.4G communication link parameters of the payment device transmitted by the payment device that supports limited-domain communication through the alternating magnetic field based on the alternating magnetic field module;

Step 320: The micro control unit sets the 2.4G communication module based on the 2.4G communication link parameters, so that the 2.4G communication module establishes a 2.4G communication link with the payment collection device;

Step 330: The micro control unit receives the transaction timestamp sent by the payment collection device based on the 2.4G communication link;

Step 340: The micro control unit generates a payment code based on the device information, code factor and transaction time stamp based on the payment code generation algorithm in the security chip;

Step 350: The micro control unit sends the payment code to the payment device through the 2.4G communication link, so that the payment device completes the payment code corresponding to the payment code through the reverse scan code payment link Payment transaction.

The following is also explained in conjunction with a complete mobile payment transaction process.

At this time, the MCU can set the 2.4G communication module according to this 2.4G communication link parameter; since this 2.4G communication link parameter is the parameter established by the payment device to establish the 2.4G communication link, when the 2.4G communication module is also set After the parameters of the 2.4G communication link are established, the 2.4G communication link with the payment collection device can be established.

After the 2.4G communication link is established, the payment collection device may send a transaction time stamp based on the 2.4G communication link; the transaction time stamp may refer to the time stamp when the payment collection device sends it. Please note that unlike the embodiment in FIG. 2, the transaction timestamp in this embodiment is provided by the payment collection device. The reason is that in this embodiment, the payment application does not participate in the generation of the payment code, but the transaction timestamp is indispensable, so the payment timestamp is provided by the collection device.

Then, after receiving the transaction timestamp based on the 2.4G communication link, the MCU can generate a payment code based on the device information, code factor, and transaction timestamp based on the payment code generation algorithm in the security chip.

It should be noted that the aging of the code factor is divided into permanent validity and long-term effectiveness. Either way, it needs to be provided by the payment application installed in the mobile terminal, specifically:

The code factor is passed in by the payment application installed in the mobile terminal through the Bluetooth communication link. To this end, a Bluetooth communication module (not shown in FIG. 3) needs to be set in the RCC module; and the Bluetooth communication module can establish a Bluetooth communication link with the mobile terminal and receive the code factor passed by the payment application based on the Bluetooth communication link .

Among them, the long-term effective code factor will eventually be invalid. For this type of code factor; whenever the payment application is opened, the payment application can pass the latest code factor to the SE in the RCC module through the Bluetooth communication link To update the code factor stored in the SE.

After the SE generates the payment code, the MCU can send the payment code to the collection device based on the previously established and maintained 2.4G communication link, so that the collection device completes the transaction through the anti-scan code payment link The payment transaction corresponding to the payment code.

The anti-scanning code payment link, as shown in FIG. 3, is a link established between the payment collection device and the payment operation server, and is used to execute the payment transaction request of the payment collection device. After receiving the payment code, the collection device can scan the payment code to obtain the account information of the payer, assemble the collection request after adding the information such as the amount to be collected, and send the collection request based on the anti-scanning code payment link To the payment operation server, the payment operation server completes the transaction according to the message in the payment request, for example, in the case of determining the payer account, the payee account and the payment amount, the payment amount is deducted from the payer account Funds, and inject the deducted funds into the recipient's account.

Can be applied in public transportation scenarios:

It can also be used in daily shopping scenarios:

Please note that the above application scenarios are only a few examples, and are not limited to be implemented in the above application scenarios; it should be understood that all mobile payment application scenarios can implement the mobile payment solution provided in this specification.
