Detailed ways

The technical solutions of the present application will be clearly and completely described in the following with reference to the specific embodiments of the present application and the corresponding drawings. It is apparent that the described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present specification without departing from the inventive scope are the scope of the application.

FIG. 1 is a schematic diagram of a system architecture involved in a payment and tax refund by a user through an agency in the prior art. As shown in the figure, users paying for overseas non-duty-free shops need to make a tax refund appointment at the tax refund counter, or a credit card guarantee refund, or Alipay tax refund business. There are two sets of systems at the merchant end, namely, the payment system and the tax refund system, which are used for payment and tax refund respectively. The counters are different, the operation is separated, and the tax refund is more complicated when the tax refund is made through a third-party agency. The specific processes include:

S101, the user goes to pay the counter payment;

S103, take the passport and mobile phone number to the tax refund counter, and the mobile phone number and the payment client are bound in advance;

S105, the tax refund counter sends the tax refund information, passport and mobile phone number to the tax refund agency;

S107, the tax refund agency sends a mobile phone number and a tax refund message to the payment system;

S109. The payment institution sends the tax refund client account to the tax refund agency;

S111, sending a payment client account to the user for confirmation;

S113, the user returns a confirmation message to the tax refund agency;

S115, returning a message to the payment system;

S117, the payment system sends a reminder message to the user to remind the departure tax rebate;

S119, the tax refund agency sends relevant information to the customs;

S121, the user goes to the customs to confirm the departure;

S123, the customs sends the tax refund related information to the tax refund agency;

S125, the tax refund agency sends the confirmation tax refund information to the payment system;

S127, the payment system performs tax refund and transfers the money to the user account.

The above process is simply described as follows: after the user purchases, the user requests to connect to the payment system at the payment counter to complete the payment; the user goes to the tax refund counter, submits a tax refund request to the tax refund system, and refunds the tax; the user confirms the departure and completes the tax refund. .

Based on this, the embodiment of the present specification provides a tax refund scheme, in which the merchant obtains the user identifier for payment, and after the payment is successful, the tax refund amount is determined according to the user identifier and the transaction information, and then the tax refund request is initiated to the tax refund system.

FIG. 2 is a schematic diagram of an application scenario involved in the tax refund scheme provided by the embodiment of the present specification. In this scenario, the tax refund system and the payment system may be two subsystems that belong to two different functions in a certain system, or two systems that have business cooperation relationship with each other, and only the payment system is required. And the tax refund system can accurately identify the same user identification (for example, bank card number, mobile phone number, digital object unique identifier DOI for payment, etc.).

In the embodiment of the present specification, the provided tax refund method may specifically include a merchant side aspect and a tax refund system aspect. For the merchant side aspect, the execution process includes the following steps, as shown in FIG. 3 , FIG. 3 is the present specification. A schematic diagram of the process of the tax refund method for the merchant side provided by the embodiment, including:

S301. The merchant obtains the user identifier.

As described above, the user identifier may be, for example, a bank card number, a mobile phone number, a DOI for payment (ie, a barcode or a two-dimensional code for payment, etc., which includes corresponding account information of the user on the payment client, generally For multiple digits). The user identification can be obtained by swiping, scanning, or manually inputting.

S303. Transmit transaction information and the user identifier to the payment system, so that the payment system completes the payment.

The transaction information generally includes the user identification, the merchant identification, the transaction amount, and the like. The payment process involved in this step is a conventional scan code payment or credit card payment process, and will not be described again.

S305. When receiving the response message of the payment success sent by the payment system, determine the tax refund amount according to the transaction information.

The response message may be a specific notification message or a message such as an Acknowledgement (ACK) mechanism. Generally speaking, in an actual application, when the payment is successfully ended, the payment system sends a notification message to both the user and the merchant, that is, the notification message is used as the response message.

After receiving the response message indicating that the payment is successful, the merchant calculates a specific tax refund amount according to the transaction situation. The rules of calculation are based on the provisions of regional laws and the specific circumstances of the goods. For example, in country H, the amount of tax refund = transaction amount * 10%.

S307. Send a tax refund request carrying the tax refund amount and the user identifier to a tax refund system, so that the tax refund system performs a tax refund.

As described above, the user has provided the corresponding user identifier (bank card number, or DOI containing the user ID) when the payment is made. At this time, the merchant terminal does not need to swipe the card again or scan the two-dimensional code to determine the previously obtained user identifier. For the user ID that needs to be refunded. No need for the user to go to another window to operate again.

As a specific implementation manner, in step S301, the merchant obtains the user identifier, including the following two most common methods:

First, the merchant obtains the user's bank card number (including various credit cards) for the corresponding payment and tax refund.

Secondly, the user provides the DOI to the merchant through the client, and the merchant obtains the corresponding digital code by scanning the code to perform corresponding payment and tax refund.

In practical applications, there may be other user identifiers that can characterize the user (eg, an ID card, a phone number bound to the payment system, etc.), as long as the payment system and the tax refund system can simultaneously identify the user identity, in this specification In the embodiment, it can also be used for payment and tax refund.

As a specific implementation manner, in S305, determining the tax refund amount according to the transaction information may be confirmed by the merchant itself, or may be confirmed by the relevant national taxation department, specifically, the following manners are as follows:

Locally, according to the preset tax refund rule, the tax refund amount is determined by the transaction information; or

Sending the transaction information and the user identifier to the relevant tax refund institution, and receiving the refund amount returned by the relevant tax refund agency. The tax refund agency here may be a third-party agency tax refund agency (the third-party tax refund agency usually has a business cooperation relationship with the customs, which collects a certain fee for the refund), or it may be the local customs department.

As a specific manner, the foregoing solution sends a tax refund request carrying the tax refund amount and the user identifier to the tax refund system (after the tax refund amount has been confirmed), and may also pre-authorize the tax refund system, so that Real-time tax rebates, pre-authorization methods include:

Sending a pre-authorization request carrying the user identifier and the tax refund amount to the tax refund system, so that the tax refund system receives the pre-authorization of the tax refund user; receiving a response of the pre-authorization sent by the tax refund system; wherein the pre-authorization is used for tax refund The system freezes the pre-authorization amount of the account corresponding to the tax refund identifier, and the pre-authorization amount is related to the tax refund amount.

Specifically, when the user performs a credit card payment, the manner of pre-authorization may be credit card pre-authorization. When the user performs client-side scan code payment, the pre-authorization method may be Internet financial credit (that is, the Internet financial credit product provided by the tax refund system provides pre-authorization to the user).

After the pre-authorization is successful, the tax refund system will return a response message of successful pre-authorization, which is similar to the response message of the above-mentioned payment success, and is used to notify the user and the merchant that the pre-authorization has passed, so that the merchant performs the next process ( That is, initiate a tax refund request).

For the aspect of the tax refund system, the flow of the execution includes the following steps. As shown in FIG. 4, FIG. 4 is a schematic flowchart of the execution of the tax refund system provided by the embodiment of the present specification, including:

S401. The tax refund system receives a tax refund request sent by the merchant and carries the tax refund amount and the user identifier; wherein the tax refund request is initiated by the merchant when receiving the response message of the payment success sent by the payment system.

S403. Confirm an account corresponding to the user identifier.

S405. Transfer the tax refund amount to the corresponding account.

Specifically, the tax refund system may be real-time when the tax refund is made, or may be refunded after confirming that the user has left the country. However, in any case, in the process, the user does not have to go to the counter of the other tax refund agency to perform the tax refund operation after the payment is made at the merchant's counter, thereby improving the user experience.

As a specific implementation manner, before the tax refund system performs the tax refund, the merchant can make an appointment refund according to the needs of the user, that is, the user passes the merchant (in general, the password can be secured by the user; since the payment process has been input If you pass the password, you can pre-authorize the tax refund system without having to enter the password, and freeze a certain amount in the user account. The specific steps are as follows:

The tax refund system receives a pre-authorization request sent by the merchant to carry the user identification and the tax refund amount;

Confirming an account corresponding to the user identifier;

Determining the pre-authorization amount according to the preset rules and the refund amount, and freezing;

Sending a response message of successful pre-authorization to the merchant, so that the merchant initiates a tax refund request.

In the above process, the pre-authorization amount (ie, the frozen amount) is related to the tax refund amount. The preset rule includes multiplying the tax refund amount by a certain coefficient. For the average user, the pre-authorization amount should be greater than the tax refund amount (ie, The pre-authorization can only be completed if the coefficient is greater than 1). In the process, if the remaining amount or the credit amount in the user account is less than the pre-authorized amount, there is a possibility that the pre-authorization fails.

In practical applications, the pre-authorization amount can also be determined in conjunction with the credit status of the user. Users with higher credits can pre-authorize only a lower pre-authorization amount or even a pre-authorization amount. For example, the user's credit is evaluated based on the user's behavior. If the user's credit score exceeds the specified score (for example, 1000 points), the pre-authorization can be implemented without freezing the pre-authorization amount.

It should be noted that during the pre-authorization process, only a certain amount in the user account is frozen, and no deduction is made. The response message regarding the successful pre-authorization has been described in the foregoing and will not be described here.

After the tax refund system accepts the pre-authorization of the user, for S405, the tax refund amount is transferred to the corresponding account, and the tax refund may be performed as follows:

Determining whether the corresponding account has a pre-authorization, and if so, directly transferring the tax refund amount to the corresponding account.

That is, for a pre-authorized successful account, a real-time tax refund can be adopted, and the user can receive the tax refund amount at the same time as the payment is successful, without waiting for several weeks.

Of course, if the user pre-authorization fails, or the user does not want to use the pre-authorization method to refund the tax, the tax refund may be performed in a conventional manner, that is, for S405, the refund amount is allocated to the corresponding account. Take the following methods to refund the tax:

When the user's departure confirmation message is received, the tax refund amount is transferred to the corresponding account.

That is, the user stamps the tax refund form at the customs when leaving the country, and sends it to the institution of the tax refund system by means of postal delivery or delivery at a designated place. After confirmation, the tax refund is made.

Through the above solution provided by the embodiment of the present specification, the user provides the merchant bank card number or payment code, and the merchant obtains the user identifier and then performs payment. After the payment is successful, the tax refund amount is determined according to the user identifier and the transaction information, and then the tax refund is performed. The system initiates a tax refund request. Through the above scheme, the payment and the tax refund are combined, and the user only needs to swipe the card once, or scan the code once, and after completing the payment, the tax refund can be realized, without having to run two counters, filling in the cumbersome information form, and improving the user at the time of departure tax refund. Experience. In addition, combined with user pre-authorization (for example, credit card guarantees, Internet credit guarantees, etc.), real-time tax refunds can be completed to further enhance the user experience.

In the above solution, when the real-time tax rebate is performed, the user authorizes the tax refund system to pre-authorize, and freezes part of the funds in the account. After the user returns to the country, the part of the funds needs to be thawed. Based on this, the embodiment of the present specification also provides Another method of tax refund, as shown in FIG. 5, FIG. 5 is a schematic flow chart of another method for refunding tax provided by an embodiment of the present specification, after receiving the return confirmation information of the customs for user authentication (for example, the user provides the customs cover The return document of the chapter; or, the customs sent the return certificate of the relevant user to the tax refund system), including:

S501: Obtain a user identifier; for example, manually input a user's passport ID, a mobile phone account bound to the tax refund system, a user ID number, and the like; or provide a QR code containing the user identification information through the client for scanning, etc. Wait.

S503. Send a pre-authorization amount thawing request carrying the user identifier to the tax refund system, so that the tax refund system unfreeze the pre-authorization amount that has been frozen in the account corresponding to the user identifier; wherein the frozen pre-authorization amount The authorized amount is generated by the user through a pre-authorized tax refund during the payment process.

The above device may also be referred to as a pre-authorization de-freezing device, and the user may initiate a thaw request on the device after returning home. When the tax refund system receives the corresponding thawing request, the pre-authorization amount in the user account is thawed, and the corresponding message is sent to the user. Through the above method, the user can conveniently unfreeze the pre-authorization amount frozen during the payment and tax refund process.

In order to make the solution of the embodiment of the present specification more plain and clear, a specific example of the payment and tax refund integration is given below, as shown in FIG. 6, FIG. 6 is an exemplary tax refund scheme provided by the embodiment of the present specification. A schematic diagram of the process, which includes:

S601: The user opens the client and provides a two-dimensional code for payment;

S603. The merchant scans the code to obtain the user identifier.

S605, confirm transaction information, and initiate a payment request to the payment system;

S607, the payment system returns a payment success message to the merchant;

S617, the tax refund system handles the tax refund;

S619, the payment is made to the user account, and the result is returned to the merchant and the user.

S621, the user obtains the returning confirmation material through the customs, and requests the thawing device to unfreeze the pre-authorization amount;

S623. The thawing device scans the QR code of the user client to obtain a user identifier.

S625, sending a defrosting request to the tax refund system;

S627, unfreezing the user pre-authorization amount;

S629, sending a thaw message to the user.

Through the above process, the user can realize the real-time tax refund when the purchase payment is realized, and then the pre-authorization amount is released after returning to the country.

The various embodiments in the specification are described in a progressive manner, and the same or similar parts between the various embodiments may be referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, for the device, the device, and the media type embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method embodiment, which will not be repeated here.

The foregoing description of the specific embodiments of the specification has been described. Other embodiments are within the scope of the following claims. In some cases, the acts or steps or modules recited in the claims can be performed in a different order than in the embodiments and the desired results can still be achieved. In addition, the processes depicted in the figures are not necessarily in a particular order or in a sequential order to achieve the desired results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.

In the 1990s, improvements to a technology could clearly distinguish between hardware improvements (eg, improvements to circuit structures such as diodes, transistors, switches, etc.) or software improvements (for process flow improvements). However, as technology advances, many of today's method flow improvements can be seen as direct improvements in hardware circuit architecture. Designers almost always get the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that the improvement of a method flow cannot be implemented by hardware entity modules. For example, a Programmable Logic Device (PLD) (such as a Field Programmable Gate Array (FPGA)) is an integrated circuit whose logic function is determined by the user programming the device. Designers program themselves to "integrate" a digital system on a single PLD without having to ask the chip manufacturer to design and fabricate a dedicated integrated circuit chip. Moreover, today, instead of manually making integrated circuit chips, this programming is mostly implemented using "logic compiler" software, which is similar to the software compiler used in programming development, but before compiling The original code has to be written in a specific programming language. This is called the Hardware Description Language (HDL). HDL is not the only one, but there are many kinds, such as ABEL (Advanced Boolean Expression Language). AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., are currently the most commonly used VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. It should also be apparent to those skilled in the art that the hardware flow for implementing the logic method flow can be easily obtained by simply programming the method flow into the integrated circuit with a few hardware description languages.

The controller can be implemented in any suitable manner, for example, the controller can take the form of, for example, a microprocessor or processor and computer readable storage storing computer readable program code (eg, software or firmware) executable by the (micro)processor. In the form of media, logic gates, switches, Application Specific Integrated Circuits (ASICs), programmable logic controllers, and embedded microcontrollers, examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM The Microchip PIC18F26K20 and the Silicone Labs C8051F320, the memory controller can also be implemented as part of the memory's control logic. Those skilled in the art will also appreciate that in addition to implementing the controller in purely computer readable program code, the controller can be logically programmed by means of logic gates, switches, ASICs, programmable logic controllers, and embedding. The form of a microcontroller or the like to achieve the same function. Such a controller can therefore be considered a hardware component, and the means for implementing various functions included therein can also be considered as a structure within the hardware component. Or even a device for implementing various functions can be considered as a software module that can be both a method of implementation and a structure within a hardware component.

The system, device, module or unit illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product having a certain function. A typical implementation device is a computer. Specifically, the computer can be, for example, a personal computer, a laptop computer, a cellular phone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or A combination of any of these devices.

For the convenience of description, the above devices are described separately by function into various units. Of course, the functions of the various units may be implemented in one or more software and/or hardware when implementing embodiments of the present specification.

Those skilled in the art will appreciate that embodiments of the present invention can be provided as a method, system, or computer program product. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment, or a combination of software and hardware. Moreover, the invention can take the form of a computer program product embodied on one or more computer-usable storage media (including but not limited to disk storage, CD-ROM, optical storage, etc.) including computer usable program code.
