Detailed Description

The embodiment of the specification provides a method, a device and equipment for processing offline transactions.

In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present specification without any inventive step should fall within the scope of protection of the present specification.

Example one

As shown in fig. 1, an execution body of the method may be a first terminal of a transaction initiator, where the first terminal may be a mobile terminal device such as a mobile phone and a tablet computer, or a computer device such as a notebook computer or a desktop computer. The method may specifically comprise the steps of:

in step S102, information of the current network connection state of the first terminal is acquired for the target transaction.

The target transaction may be any transaction, for example, a user purchases a certain commodity in an offline store opened by a certain merchant, and the user settles the purchased commodity with the merchant through a payment application installed in a first terminal of the user, so as to form a transaction. The network connection state can be used for representing the condition that the terminal device is connected with the network, and the network connection state can comprise unconnected state, connected state and the like. The first terminal may be a terminal device used by the transaction initiator, and the first terminal may be a mobile terminal device such as a mobile phone and a tablet computer, or a computer device such as a notebook computer or a desktop computer.

In the implementation, the off-line transaction is an important supplement to the on-line transaction in the state without network connection, and currently, the off-line transaction is still in the initial development and user education stages, and the commonly used off-line transaction modes may include off-line transaction processing by scanning an off-line transaction graphic code (such as a two-dimensional code, etc.), off-line transaction processing by approach communication, off-line transaction processing by off-line voiceprint, off-line transaction processing by bluetooth, etc., but the off-line transaction processing modes are respectively provided by different organizations or applications, that is, different organizations or applications are provided with specific off-line transaction modes provided for the user to use, for example, some financial institutions provide the user with a mode of off-line transaction processing by scanning an off-line transaction graphic code, and other financial institutions provide the user with a mode of off-line transaction processing by approach communication Some financial institutions provide offline transaction processing modes through a bluetooth mode for users, so that if a user needs to perform offline transaction, only an offline transaction mode set by the financial institution corresponding to the transaction mode used by the user can be used to complete a certain transaction, if the user needs to use a certain offline transaction mode, an application program provided by the financial institution corresponding to the offline transaction mode needs to be installed, so that the transaction efficiency is low, and the transaction success rate is low, and if the user does not install the application program, the user needs to perform operations of downloading, installing, registering an account and the like, so that the transaction efficiency and the transaction success rate are further low, and therefore, a technical scheme for selecting different offline transaction modes according to different scenes needs to be provided. The embodiment of the present specification provides an implementable technical solution, which may specifically include the following contents:

the offline transaction may be a transaction in which both the terminal devices used by both the parties of the transaction are offline (i.e., not connected to a network or not connected to a network), or may be a transaction in which both the parties of the transaction are offline. As shown in fig. 2, for the terminal device (i.e. the first terminal) of the transaction initiator, the transaction initiator may select a transaction object that needs to perform a transaction (for example, the transaction initiator may select an item that needs to be purchased in an off-line shop), and after the selection is completed, the selected item may be provided to a manager for settlement, and the manager may calculate a resource (such as an amount of money that needs to be paid, etc.) that needs to be transferred for the selected item. After the calculation is completed, the transaction initiator needs to provide the information of the account for resource transfer to the administrator through the first terminal, and at this time, the information of the current network connection state may be acquired, where the manner of acquiring the information of the network connection state may include multiple manners, for example, the first terminal may detect the network connection state periodically or aperiodically and record the information of the network connection state.

In addition, the first terminal may synchronize information of the network connection state thereof with a designated server (e.g., a transaction server, etc.), if the time length of the network connection state information of the first terminal not updated exceeds a preset time length threshold, the network connection state of the first terminal may be set to be unconnected or disconnected, or the designated server may periodically or aperiodically send a heartbeat request or a detection request for network connection to the first terminal, the first terminal may send the information of the network connection state thereof to the designated server, the designated server may record the information of the network connection state, if the designated server does not receive the information of the network connection state of the first terminal within a preset time length, the network connection state of the first terminal may be set to be unconnected or disconnected, and the like, which may be set according to actual conditions, the examples in this specification do not limit this.

In step S104, if the current network connection state of the first terminal is connected and the network connection state of the second terminal of the transaction target party of the target transaction is determined to be unconnected, or the current network connection state of the first terminal is unconnected, it is determined whether the first terminal is capable of outputting the transaction identifier for triggering the offline transaction processing of the target transaction.

The transaction target party may be a party providing a transaction object to the user of the first terminal, where the transaction object may be an object that needs to be transacted, such as a commodity, and the transaction target party may be a merchant. The second terminal may be a mobile terminal device such as a mobile phone, a tablet computer, or a computer device such as a notebook computer or a desktop computer, or may be a POS machine or a cash register, which may be specifically set according to an actual situation, and this is not limited in this description embodiment. The transaction identification code may be used to provide information of an account that needs to be used for performing a certain transaction, and in practical applications, a coding manner may be preset, the information of the account and the like are coded by the coding manner to obtain a corresponding coding result, the coding result may be used as the transaction identification code, the transaction identification code may include a plurality of different presentation manners, for example, the transaction identification code may be a graphic code (specifically, a two-dimensional code or a barcode, and the like), the transaction identification code may also be coded based on a biological characteristic of a user (for example, a voiceprint feature code, a facial feature code, and the like), and may be specifically set according to an actual situation, which is not limited in this description embodiment.

In practice, the second terminal may detect the network connection status periodically or aperiodically, and record the information of the network connection status. In addition, the second terminal can also synchronize the information of the network connection state thereof with the designated server, if the time length for which the information of the network connection state of the second terminal is not updated exceeds the preset time length threshold, the network connection status of the second terminal may be set to unconnected or network connected and the like, alternatively, the designated server may also periodically or aperiodically send a heartbeat request or a detection request for the network connection to the second terminal, the second terminal may send information of its network connection status to the designated server, the designated server may record the information of the network connection status, if the designated server does not receive the information of the network connection status of the second terminal within the preset time period, the network connection state of the second terminal may be set to be unconnected or disconnected, and the network connection state may be set according to actual situations, which is not limited in this embodiment of the specification.

If the first terminal detects that the current network connection state is connected, the first terminal may send a request for acquiring information of the network connection state of the second terminal to the designated server, the designated server may send the information of the network connection state of the second terminal to the first terminal, if the network connection state of the second terminal is unconnected, the first terminal may determine that an offline transaction is required, at this time, a processing procedure for generating a transaction identification code for processing the offline transaction for a target transaction, and an operating state of each involved component (such as a load condition of a processor, a storage state of a memory, and the like) may be detected, and a processing procedure for outputting the transaction identification code, and an operating state of each involved component (such as an operating state of a display component, a load condition of a processor, and the like) may be detected, through the detection processing, it may be determined whether the first terminal is capable of outputting the transaction identification code for triggering the offline transaction processing on the target transaction, for example, if one or more processing processes are abnormal and/or one or more related components are abnormal, it may be determined that the first terminal is incapable of outputting the transaction identification code for triggering the offline transaction processing on the target transaction, otherwise, the first terminal is capable of outputting the transaction identification code for triggering the offline transaction processing on the target transaction, which may be specifically set according to an actual situation, which is not limited in the embodiments of the present specification.

In addition, if the first terminal detects that the current network connection state is unconnected, the first terminal may determine that an offline transaction needs to be performed, and at this time, a processing procedure for generating a transaction identification code for performing offline transaction processing on the target transaction and an operating state of each related component may be detected, and in addition, a processing procedure for outputting the transaction identification code and an operating state of each related component may also be detected.

In step S106, based on the determination result of whether the first terminal can output the transaction identifier, an offline transaction policy corresponding to the determination result is selected, and an offline transaction process is performed on the target transaction with the second terminal based on the selected offline transaction policy.

The offline transaction policy may be a transaction policy including information related to an offline transaction manner, a processing flow of the offline transaction, and the like, and the offline transaction policy may include multiple types, for example, the offline transaction policy may include a policy of establishing a connection through bluetooth to perform offline transaction, a policy of establishing a connection through a radio frequency signal (such as an infrared signal) to perform offline transaction, and the like, which may be specifically set according to an actual situation, and this is not limited in this specification.

In implementation, different offline transaction strategies can be constructed in advance according to actual conditions, and the constructed offline transaction strategies can be stored in a specified storage device or a blockchain system. If the first terminal is determined to be capable of outputting the transaction identification code based on the judgment result, an offline transaction strategy corresponding to the judgment result can be selected from the storage device or the blockchain system, and the first terminal and the second terminal perform offline transaction processing based on the selected offline transaction strategy. For example, if it is determined that the first terminal can output the transaction identifier based on the determination result, the first terminal may output the transaction identifier, the second terminal may acquire the transaction identifier through a decoding and identifying component of the transaction identifier, and then may establish a designated connection with the first terminal (e.g., establish a connection through bluetooth or an appointed local area network, etc.), through which an offline transaction process may be performed between the first terminal and the second terminal (i.e., the second terminal parses the transaction identifier, may obtain account information of a transaction initiator, and may perform a resource transfer process based on the account information and transaction information of a target transaction, and after the resource transfer process is successful, the second terminal may send a notification message that the resource transfer process is successful to the first terminal, etc.).

The embodiment of the present specification provides a processing method of an offline transaction, where a first terminal of a transaction initiator acquires information of a current network connection state of the first terminal for a target transaction, and if the current network connection state of the first terminal is connected and it is determined that a network connection state of a second terminal of a transaction target party of the target transaction is unconnected or the current network connection state of the first terminal is unconnected, it is determined whether the first terminal is capable of outputting a transaction identification code for triggering offline transaction processing on the target transaction, then, based on a determination result that the first terminal is capable of outputting the transaction identification code, an offline transaction policy corresponding to the determination result is selected, and the target transaction between the first terminal and the second terminal is processed offline based on the selected offline transaction policy, so that the offline transaction can be performed according to the network connection state, the second terminal of the transaction initiator, The payment scene and the payment environment adaptively select the off-line transaction mode which is most suitable for the current situation, so that the off-line transaction efficiency and the off-line transaction success rate can be improved, and the transaction experience of the user is greatly improved.

Example two

As shown in fig. 3, an execution body of the method may be a first terminal of a transaction initiator, where the first terminal may be a mobile terminal device such as a mobile phone and a tablet computer, or a computer device such as a notebook computer or a desktop computer. The method may specifically comprise the steps of:

in step S302, information of the current network connection state of the first terminal is acquired for the target transaction.

In step S304, if the current network connection state of the first terminal is connected and the network connection state of the second terminal of the transaction target party of the target transaction is determined to be unconnected, or the current network connection state of the first terminal is unconnected, it is determined whether the first terminal is capable of outputting the transaction identifier for triggering the offline transaction processing of the target transaction.

Wherein the transaction identification code may include a graphic code, a code of a biometric characteristic of the user of the first terminal. The graphic code may be a graphic which is distributed on a plane (i.e. in two-dimensional direction) according to a certain rule by using a certain specific geometric figure and records data symbol information, and may specifically include a two-dimensional code, a bar code, and the like. The biometric features may include a plurality of features, such as a fingerprint feature, a palm print feature, a facial feature, a voiceprint feature, and the like, which may be set according to actual situations, and this is not limited in this embodiment of the specification.

For the specific processing procedures of step S302 and step S304, reference may be made to relevant contents in the first embodiment, which are not described herein again.

In addition, for the offline transaction policy related in the first embodiment, in practical applications, one or more of the offline transaction policy based on the approach communication NFC, the offline transaction policy based on the bluetooth, and the offline transaction policy based on the local area network may be included.

Based on the above, the specific processing of step S106 in the first embodiment may be various, and three alternative processing manners are provided below, and specifically, the following processing of step S306 to step S314 may be included.

In step S306, if the determination result based on whether the first terminal is capable of outputting the transaction identifier indicates that the first terminal is incapable of outputting the transaction identifier, selecting an offline transaction policy based on the incoming communication NFC as the offline transaction policy corresponding to the determination result.

In implementation, as shown in fig. 4, if the determination result indicates that the first terminal cannot output the transaction identifier, it indicates that the second terminal cannot perform the offline transaction by identifying the transaction identifier, and can only select another method, and in addition, considering that the first terminal and the second terminal need to perform the offline transaction, the offline transaction may be performed by using an inbound communication method, specifically, an offline transaction policy based on the inbound communication NFC may be selected from a storage device or a blockchain system storing the offline transaction policy, and the offline transaction policy based on the inbound communication NFC may be used as the offline transaction policy corresponding to the determination result.

The specific processing of step S306 may be various, and the following provides an optional processing manner, which may specifically include the following: and if the judgment result based on whether the first terminal can output the transaction identification code indicates that the first terminal is in a shutdown state, selecting an offline transaction strategy based on the incoming communication NFC as the offline transaction strategy corresponding to the judgment result.

In implementation, as shown in fig. 4, if the determination result indicates that the first terminal is in the power-off state, it may be determined that the first terminal is not capable of outputting the transaction identification code, and at this time, the specific process of step S306 may be performed.

In addition to the above-mentioned process of step S106, the above-mentioned process of step S106 may also be implemented in the following manner, and may specifically include the following related contents.

In step S308, if the first terminal is indicated to be able to output the transaction identification code based on the determination result of whether the first terminal is able to output the transaction identification code, it is determined whether the second terminal is in the same local area network as the first terminal.

In implementation, as shown in fig. 4, if the determination result indicates that the first terminal is capable of outputting the transaction identification code, the first terminal may output the transaction identification code (specifically, displaying a graphic code, outputting voiceprint information (which may be text, graphic, or audio data, etc.), outputting a code of a facial feature, etc.), and the second terminal may collect the transaction identification code through a decoding and recognition component of the transaction identification code, and then determine whether the second terminal is in the same lan as the first terminal, for example, may obtain a current device list from a gateway, determine whether the information of the second terminal is included therein, if so, determine that the second terminal is in the same lan as the first terminal, otherwise, the second terminal is not in the same lan as the first terminal.

In step S310, if yes, an offline transaction policy based on the local area network is selected as the offline transaction policy corresponding to the determination result.

In implementation, as shown in fig. 4, if it is determined that the second terminal and the first terminal are in the same local area network, the local area network-based offline transaction policy may be selected from a storage device or a blockchain system storing the offline transaction policy, and the local area network-based offline transaction policy may be used as the offline transaction policy corresponding to the determination result.

In step S312, if the second terminal and the first terminal are in different lans, the offline transaction policy based on bluetooth is selected as the offline transaction policy corresponding to the above determination result.

In implementation, as shown in fig. 4, if it is determined that the second terminal is not in the same local area network as the first terminal, the offline transaction may be performed in a manner of establishing a connection through bluetooth, specifically, the offline transaction policy based on bluetooth may be selected from a storage device or a blockchain system storing the offline transaction policy, and the offline transaction policy based on bluetooth may be used as the offline transaction policy corresponding to the determination result.

In step S314, the target transaction with the second terminal is processed offline based on the selected offline transaction policy.

In implementation, as shown in fig. 4, if the selected offline transaction policy is an offline transaction policy based on NFC, the transaction initiator may bring the first terminal close to the second terminal, and establish a communication connection with the second terminal through an NFC module in the first terminal, where the NFC module may include a Security Element (SE), a contactless front-end CLF (or referred to as an NFC controller), a radio-frequency Antenna (Antenna), and the like, and through the above components of the NFC module, the first terminal may establish a communication connection with the second terminal, and may perform Secure data interaction, thereby finally completing the offline transaction.

If the selected offline transaction strategy is the offline transaction strategy based on the Bluetooth, the transaction initiator can start the Bluetooth of the first terminal, in addition, the transaction target party can also start the Bluetooth of the second terminal, then, the Bluetooth connection can be established between the first terminal and the second terminal, the communication connection is established between the Bluetooth of the first terminal and the Bluetooth of the second terminal, and based on the established Bluetooth communication connection, data interaction can be carried out between the first terminal and the second terminal, and finally, the offline transaction is completed.

If the selected offline transaction strategy is an offline transaction strategy based on a local area network, a first terminal of a transaction initiator can establish communication connection with a second terminal through a gateway of the local area network, then the first terminal can send information needing to be sent to the second terminal to the gateway, the gateway forwards the information to the second terminal, similarly, the second terminal can send the information needing to be returned to the first terminal to the gateway, the gateway forwards the information to the first terminal, and finally the offline transaction can be completed between the first terminal and the second terminal based on the interaction process.

The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using 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, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, 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 for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
