Detailed Description
With the development of mobile internet and internet financial technology, the use of two-dimensional codes to complete payment transaction in practical application is becoming more and more popular. Different payment channels correspond to different two-dimensional code generation rules, so that different two-dimensional codes are generated based on the different two-dimensional code generation rules. This means that a two-dimensional code can only be identified under the same payment channel. For example: the two-dimensional code corresponding to the payment channel A cannot be identified by the user through the client device supporting the payment channel B, and the user can only use the client device supporting the payment channel A to identify so as to finish payment or collection. Thus, for merchants engaged in production and operation activities, two-dimension codes of different payment channels are generally required to be provided for consumers, so that the consumers can conveniently select two-dimension codes suitable for themselves to pay. But for merchants may need to maintain accounts for multiple payment channels, increasing the operating costs of the merchant.
In order to solve the problems described in the present specification and achieve the purposes of the present specification, embodiments of the present specification provide a payment system, a method, a server device, a medium, and a device capable of being used for unified payment, and for a merchant user who has a large amount of payment service requirements, the payment system provided in the embodiment of the present specification may be used to establish a mapping relationship between a unified payment account and feature information of two-dimensional codes generated by different payment channels in the payment system by extracting the feature information of the two-dimensional codes, and when a consumer user scans the two-dimensional codes provided by the merchant user for payment, the unified payment account of the merchant user may be determined based on the feature information of the two-dimensional codes and the pre-established mapping relationship, so that the merchant user uses the unified payment account to collect payment amounts paid by the consumer through different payment channels, thereby effectively improving uniformity and convenience of payment, and improving user experience of the consumer for two-dimensional code payment.
It should be noted that, the different payment channels described in the embodiments of the present disclosure may be understood as payment channels provided by different institutions, for example: a payment channel provided by a different bank, a payment channel provided by a third party payment platform, etc.; and may also be understood as payment channels provided by different paymate platforms. For example: a "UnionPay" of banking systems, an "Apple Pay" of Apple Inc., and so forth.
The two-dimensional code described in the embodiment of the present specification may refer to a cash register having a cash register function; or application code with a collection function; other forms of the material code with the collection function are also possible, and the form is not particularly limited here.

Fig. 2 is a schematic flow chart of a payment method according to an embodiment of the present disclosure. The method may be as follows.
Step 201: the second terminal device scans the two-dimensional code for collection provided by the first object through the second acquisition interface.
The application client provided in the embodiments of the present disclosure sets an acquisition interface, where the acquisition interface may correspond to an input port of hardware, or may correspond to an input port that implements a function through software, for example: a "sweep-to-sweep" function port, etc. The acquisition interface may have a function of scanning a two-dimensional code (or an applet code), may have a function of scanning and identifying a two-dimensional code (or an applet code), may have other functions, and the like. The manner in which the acquisition interface has the scanning and recognition functions is illustrated in fig. 2 of the embodiment of the present disclosure. In the embodiments of the present disclosure, "first" and "second" in the "first acquisition interface" and "second acquisition interface" have no special meaning, and only denote different interfaces, meaning that the functions corresponding to the different interfaces are different. In the embodiment of the present disclosure, the function difference between the first acquisition interface and the second acquisition interface is that: the second acquisition interface can trigger the server device to perform a "mapping relationship establishment" operation after scanning the two-dimensional code, for example: the second acquisition interface is a code scanning binding interface; the first collection interface can trigger payment after scanning the two-dimensional code, so that unified collection is realized, for example: the first acquisition interface is a code scanning payment interface.
The first object described in the embodiments of the present disclosure downloads and installs the application client in the used terminal device, and scans a plurality of different two-dimensional codes by using the second acquisition interface provided by the application client after the application client is started to run, where the two-dimensional codes have the characteristics of having a collection function.
The different two-dimensional codes recorded herein can be understood as two-dimensional codes corresponding to different payment channels, that is to say, for one of the two-dimensional codes, collection can be realized through the payment channel corresponding to the two-dimensional code; the payment channels corresponding to different two-dimensional codes are different.
For example: the two-dimensional code 1 for collecting money corresponding to the payment channel A shows that a collection account contained in the two-dimensional code 1 can collect money through a payment mode set by the payment channel A; the two-dimensional code 2 for collecting money corresponding to the payment channel B shows that a collection account contained in the two-dimensional code 2 can collect money through a payment mode set by the payment channel B; … …. Then in this illustrative embodiment, the first object may generate different two-dimensional codes for the checkout based on different paymate platforms. For example: two-dimensional code 1 and two-dimensional code 2. In step 201, the first object may scan the two-dimensional code 1 and the two-dimensional code 2 through the second acquisition interface provided by the application client running in the embodiment of the present disclosure.
Step 203: and the second terminal equipment extracts the characteristic information of the two-dimension code.
In the embodiment of the specification, the application client can send the scanned two-dimensional code to the server device, and the server device identifies the two-dimensional code; the two-dimensional code may be identified when the two-dimensional code is scanned, and the main body for identifying the two-dimensional code is not particularly limited.
Means for identifying two-dimensional codes include, but are not limited to: analyzing the two-dimensional code and extracting the characteristic information of the two-dimensional code.
Characteristic values herein include, but are not limited to: code value of the checkout code, user information, etc. The specific implementation manner used for extracting the feature information of the two-dimensional code in the embodiment of the present disclosure may be an existing implementation manner in the prior art, or may be other manners, as long as the feature information of the two-dimensional code can be obtained, and the specific implementation manner of extracting the two-dimensional code will not be described in detail here.
Step 205: the second terminal device carries the characteristic information in the collection information and sends the characteristic information to the first server device.
Step 207: the first server device determines a collection account of the first object upon receiving the collection information.
In an embodiment provided in the present specification, the first server device searches stored collection account information of the first object according to the received collection information, and determines a collection account of the first object according to the collection account information.
Specifically, after the application client is installed, the first object may receive, through the second terminal device, registration information sent by the first server device, and if the second terminal device receives the registration information, load and display the registration information, and prompt the first object to input user information, where the user information includes collection account information for collection; transmitting the user information input by the first object to the first server device; the first server device receives and stores the user information sent by the second terminal device; and determining a collection account of the first object according to the stored user information.
It should be noted that, registration on the application client is implemented through a registration page provided by the application client. The registration function is similar to the registration function described in the prior art, and detailed implementation is not repeated. The difference is that a unified collection account setting item may be included in the registration page, i.e., the first object enters an account in the unified collection account setting item, causing the account to be used to effect unified collection. In addition, the application client may also send the registration information to the server device when receiving the registration information input by the first object, where the server device configures a unified collection account for the first object, where the unified collection account is used to implement unified collection.
Step 209: the first server device establishes and stores a correspondence between the characteristic information and the collection account.
In the embodiment of the present disclosure, a collection account of a merchant may correspond to feature information of a plurality of two-dimensional codes, so that the merchant is convenient to achieve the purpose of unified collection by the method provided in the present disclosure.
In the embodiment of the present disclosure, if the merchant needs to view the correspondence established by the server device, the application client may obtain the correspondence from the server device, so that the merchant can view the bound two-dimensional code information locally. The first object can be flexibly deleted or added based on the displayed two-dimensional code information.
In the embodiment provided in the specification, the relationship between the two-dimension code for collecting money and the collecting account for collecting money is established by the merchant user in the above manner, so that the merchant user can realize unified collecting money in production and management activities by utilizing the relationship.
Step 211: the method comprises the steps that a first terminal device scans two-dimensional code information provided by a first object, extracts characteristic information corresponding to the two-dimensional code information from the two-dimensional code information, and sends the characteristic information to a first server device.
In the embodiment of the present specification, once a consumer user generates a consumption behavior in a store provided by a merchant user, and a fee is paid to the merchant user, an application client installed on the mobile device used may be started, and a two-dimensional code for collection provided by the merchant user (for example, the first object described in the embodiment of the present specification) is scanned through a first acquisition interface provided by the application client. The two-dimensional code for collecting money provided by the first object can be a plurality of codes or one code. As for which two-dimensional code the consumer user scans, the consumer user can select by himself, and only one two-dimensional code is scanned by the consumer user.
Step 213: the first server equipment receives the characteristic information sent by the first terminal equipment, and determines the receiving account of the first object corresponding to the characteristic information according to the corresponding relation between different prestored characteristic information and receiving accounts of different objects.
In the present illustrative embodiment, upon receiving the feature information, the first server device retrieves whether or not there is a correspondence relation related to the feature information based on the feature information. If the corresponding relation exists, a collection account of the first object can be determined; if the correspondence relationship does not exist, the fact that the collection account of the first object cannot be determined is meant, and at this time, the first server device may send a payment failure message to the first terminal device.
Step 215: the first server device generates payment information based on the collection account and the payment amount, and sends the payment information to the first terminal device, wherein the payment information also comprises at least one payment channel.
In the embodiment of the specification, the first server device generates a payment page based on the collection account and the payment amount, and sends the payment page to the first terminal device, wherein the payment page further comprises at least one payment channel.
Step 217: the first terminal equipment receives the payment information sent by the first server equipment, selects one payment channel from the payment channels, and sends the payment channel carried in the payment confirmation information to the first server equipment.
In the embodiment of the specification, the first terminal equipment receives, loads and displays a payment page sent by the first server equipment, and prompts a user to select a payment channel based on the payment page; and according to the payment channel selected by the user, carrying the payment channel in payment confirmation information and sending the payment confirmation information to the first server equipment.
For example: the first server device may include a plurality of payment channels in the payment page such that a consumer user may select one of the plurality of payment channels.
It should be noted that, the server device may also display a payment channel corresponding to the two-dimensional code scanned by the first terminal device in the payment page, if the payment channel corresponding to the two-dimensional code scanned is "WeChat payment", and the payment channel selected by the user is also "WeChat payment", then the second server device determined subsequently is the server device corresponding to "WeChat payment"; if the payment channel corresponding to the scanned two-dimensional code is 'WeChat payment', and the payment channel selected by the user is 'Payment', the second server device determined later is the server device corresponding to 'Payment'.
Step 219: the first server device receives the payment confirmation information sent by the first terminal device, generates a payment request according to the payment channel, the payment amount, the device identifier of the first terminal device and the collection account contained in the payment confirmation information, and sends the payment request to a second server device corresponding to the payment channel.
Step 221: and the second server equipment receives the payment request sent by the first server equipment, determines a payment account according to the equipment identifier of the terminal equipment contained in the payment request, and pays the payment amount from the payment account to the collection account.
In the embodiment of the present disclosure, when receiving a payment request sent by the first server device, the second server device searches a payment account corresponding to the device identifier according to the device identifier of the terminal device included in the payment request, generates a payment page, and sends the payment page to the first server device;

In the 90 s of the 20 th century, improvements to one technology could clearly be distinguished as improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) or software (improvements to the process flow). However, with the development of technology, many improvements of the current method flows can be regarded as direct improvements of hardware circuit structures. Designers almost always obtain corresponding hardware circuit structures by programming improved method flows into hardware circuits. Therefore, an improvement of a method flow cannot be said to be realized by a hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (e.g., field programmable gate array (Field Programmable Gate Array, FPGA)) is an integrated circuit whose logic function is determined by the programming of the device by a user. A designer programs to "integrate" a digital system onto a PLD without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Moreover, nowadays, instead of manually manufacturing integrated circuit chips, such programming is mostly implemented by using "logic compiler" software, which is similar to the software compiler used in program development and writing, and the original code before the compiling is also written in a specific programming language, which is called hardware description language (Hardware Description Language, HDL), but not just one of the hdds, but a plurality of 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., VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog are currently most commonly used. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, application specific integrated circuits (Application Specific Integrated Circuit, ASIC), programmable logic controllers, and embedded microcontrollers, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, atmel AT91SAM, microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic of the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller in a pure computer readable program code, it is well possible to implement the same functionality by logically programming the method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. Such a controller may thus be regarded as a kind of hardware component, and means for performing various functions included therein may also be regarded as structures within the hardware component. Or even means for achieving the various functions may be regarded as either software modules implementing the methods or structures within hardware components.
The system, apparatus, module or unit set forth in the above embodiments may be implemented in particular by a computer chip or entity, or by a product having a certain function.

Examples of storage media for a computer include, but are not limited to, phase change memory (PRAM), static Random Access Memory (SRAM), dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), read Only Memory (ROM), electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices, or any other non-transmission medium, which can be used to store information that can be accessed by a computing device. Computer-readable media, as defined herein, does not include transitory computer-readable media (transmission media), such as modulated data signals and carrier waves.
It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises the element.
The description may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. The specification may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices.
In this specification, each embodiment is described in a progressive manner, and identical and similar parts of each embodiment are all referred to each other, and each embodiment mainly describes differences from other embodiments. In particular, for system embodiments, since they are substantially similar to method embodiments, the description is relatively simple, as relevant to see a section of the description of method embodiments.
The foregoing is merely exemplary of the present disclosure and is not intended to limit the disclosure. Various modifications and alterations to this specification will become apparent to those skilled in the art. Any modifications, equivalent substitutions, improvements, or the like, which are within the spirit and principles of the present description, are intended to be included within the scope of the claims of the present description.
