[0056] In order to better understand the above technical scheme, the technical scheme of the embodiments of this specification is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical scheme of the embodiments of this specification, rather than limitations on the technical scheme of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0057] This specification embodiment provides a transaction method, which is applied to a server, such as Figure 1 FIG. 1 is a flowchart of a transaction method provided in an embodiment of the present specification, and the method includes the following steps:

[0058] Step S11: after the power source refueling of the vehicle is completed, receiving order information sent by the payment terminal of the target refueling station by scanning the target identification code, wherein the target identification code is an identification code associated with the target account, and the order information includes the transaction amount corresponding to the power source refueling and the target transaction amount corresponding to the target identification code;

[0059] Step S12: when the transaction amount is greater than the target transaction amount, deducting the target transaction amount from the target account; and

[0060] Step S13: determining the difference between the transaction amount and the target transaction amount, so that the target user performs a payment operation based on the difference.

[0061] The transaction method provided in the embodiments of this specification can be applied to the power source replenishment scenario of corporate vehicles. For example, a company is equipped with multiple vehicles. When replenishing the power source of any of the vehicles, the transaction method provided in this solution can be executed. Of course, the transaction method provided in the embodiments of this specification can also be applied to the power source replenishment scenario of private vehicles. For example, when a family has multiple vehicles and different family members use different vehicles, in order to facilitate the management of the power source replenishment costs of the vehicles and improve transaction efficiency, power source replenishment transactions can also be carried out through the method provided in this solution.

[0062] The method in the embodiments of this specification can be applied to a server, which can be a power source supply station and is used to provide transaction-related services. The server can communicate with user terminals, payment terminals of supply stations and other devices.

[0063] In step S11, the vehicle can be a company vehicle or a family vehicle, which is not limited here. For different types of vehicles, the power source can also be different. For example, for a gasoline vehicle, the power source replenishment is refueling; for an electric vehicle, the power source replenishment is charging.

[0064] The target identification code may be an identification code associated with a target account. For example, when the vehicle is a corporate vehicle, the target account may be a corporate account opened by the company for power source replenishment. When the vehicle is a family vehicle, the target account may be a personal account of a family member. It should be noted that the target identification code may be associated with one or more target accounts. For example, a company may open two accounts, and the target identification code may be associated with both accounts. When executing a transaction operation, one account may be selected for the transaction, or when the balance of one account is insufficient, the balance of another account may be used for the remaining part of the transaction. The target identification code may be in the form of a graphic code, such as a barcode, a QR code, etc. It may also be in other forms of identification codes, which are not limited here.

[0065] In the embodiments of this specification, the target identification code can be applied for in advance by the user, or can be assigned to each vehicle by the manager of the target account. Taking the user applying for the target identification code as an example, the specific implementation method is as follows: in response to the identification code application request sent by the terminal device of the target user, based on the preset transaction amount of the target account, the target identification code is assigned to the target user, and the target user is bound to the target identification code;

[0066] The first amount corresponding to the target identification code is deducted from the preset transaction amount.

[0067] Specifically, the preset transaction limit can be the total limit of the target account. Taking a corporate account as an example, the preset transaction limit can be the total amount of money deposited by the enterprise in the account. Based on the preset transaction limit, the identification code can be assigned to the target account in a variety of ways. Below, taking the target account as a corporate account as an example, two of the implementation methods are described.

[0068] The first implementation method: The enterprise can set the transaction limit for each identification code, and then divide the preset transaction limit based on the transaction limit. For example, if the enterprise sets the transaction limit for each identification code to 100 yuan and the preset transaction limit to 1,000 yuan, the preset transaction limit can be divided into 10 parts, and the transaction limit of each part is 100 yuan. Then, for each divided transaction limit, a corresponding identification code is assigned. After the server receives the identification code application request from the target user, one of the identification codes is assigned to the target user.

[0069] Of course, the set transaction amount for each identification can be the same or different. For example, the enterprise sets three transaction amounts, namely 100 yuan, 200 yuan, and 300 yuan. Correspondingly, the preset transaction amount can be divided according to the above three transaction amounts. The number of each transaction amount can be set or random. Further, a corresponding identification code is assigned to each divided share. After the server receives the identification code application request from the target user, it can randomly select one of the assigned identification codes and assign it to the target user, or select an identification code according to the amount value applied by the target user, and send it to the user terminal as the target identification code.

[0070] In the specific implementation process, the total amount of the enterprise's deposits and payments can be divided according to the set transaction limit, and cards can be made for the divided limits. A corresponding identification code (such as a QR code) is assigned to each card, so that the user can apply for the identification code and present the identification code for payment when the power source is replenished. In the embodiment of this specification, for the target account, since it is divided into at least one transaction limit, the target account corresponds to at least one identification code. Among them, the identification code can be pre-generated, for example, it has been configured before the user sends an application request in the manner described above, and it can also be generated in real time based on the user's application request. For example, after receiving the user's identification code application request, the server divides a portion of the total preset transaction limit based on the transaction limit set by the enterprise, and generates a corresponding identification code for the limit, which is fed back to the user terminal as the target identification code.

[0071] The second implementation method: When the user initiates an identification code application request, the identification code application request can carry the transaction amount entered by the user. Specifically, taking corporate vehicles as an example, there may be differences in the vehicles equipped by the enterprise. For example, some corporate vehicles have high fuel consumption; some corporate vehicles have large fuel tanks; some corporate vehicles are used frequently and the power source is replenished frequently; some corporate vehicles are used less frequently and the power source is replenished less frequently. It can be seen that the actual demand for power source replenishment is different for different vehicles. Therefore, the target user can apply for a reasonable transaction amount based on the actual power source replenishment demand of the vehicle. After receiving the application request, the administrator can review the transaction amount entered by the target user to determine whether the transaction amount entered by the target user is consistent with the actual use of the vehicle. Alternatively, the input range of the transaction amount can be pre-configured. If the transaction amount entered by the target user is within the input range, the transaction amount entered by the user can be used as the transaction amount of the identification code.

[0072] Furthermore, after the target identification code is determined, the target identification code is bound to the target user, for example, the identification mark of the target identification code is associated with the user information of the target user. After the power source replenishment of the vehicle is completed, the target identification code is scanned by the payment terminal of the target supply station, such as a POS machine, to obtain the target transaction amount corresponding to the target identification code. The target transaction amount may be the maximum amount that the target identification code can currently trade. Among them, when the target identification code contains the target transaction amount information, the target transaction amount can be directly obtained by parsing the target identification code through the payment terminal; when the target identification code does not contain the target transaction amount information, the payment terminal can send a transaction amount acquisition request to the server and receive the target transaction amount corresponding to the target identification code fed back by the server. The payment terminal generates order information based on the target transaction amount and the transaction amount corresponding to the current power source replenishment, and sends the order information to the server.

[0073] In step S12, after receiving the order information, the server determines whether the transaction amount corresponding to the current power source replenishment is greater than the target transaction amount. Among them, if the transaction amount of the current power source replenishment is less than or equal to the target transaction amount of the transaction card corresponding to the target identification code, the transaction amount can be directly deducted from the target account. If the transaction amount of the current power source replenishment is greater than the target transaction amount, it means that the target transaction amount cannot meet the amount consumed by this power source replenishment. At this time, the target transaction amount is first deducted from the target account, and then the difference between the transaction amount and the target transaction amount is calculated through step S13, and the difference is fed back to the payment terminal. The payment terminal generates payment information based on the difference, or the server directly determines the payment information based on the difference, so that the user pays the difference.

[0074] For example, if the target transaction amount corresponding to the target identification code is 200 yuan, and the transaction amount consumed for the vehicle's power source replenishment is 320 yuan, 200 yuan will be deducted from the target account first, and then the payment terminal will generate payment information based on the remaining 120 yuan difference, so that the user can pay the difference.

[0075] It should be noted that when the payment terminal generates payment information based on the difference, the payment method of the payment information can be determined based on the payment habits of the target user. For example, based on the payment methods in the historical transaction records of the target user, the most frequently used payment method is selected as the final payment method. Alternatively, the final payment method can be determined based on the choice of the target user.

[0076] The solution of the embodiment of this specification can effectively allocate the shares of the target account in order to manage the funds of the target account, and conduct power source replenishment transactions based on the allocated shares, thereby achieving accurate management of the funds of the target account. At the same time, in order to ensure that the funds of the target account are easy to manage and the funds of the target account are safe, in the embodiment of this specification, when the transaction amount exceeds the target transaction amount of the target identification code, the difference needs to be paid by the target user, and the transaction will not be conducted through the target account. Of course, the difference can also be paid through the target account. For example, if the remaining balance of the target account is sufficient to pay the difference, the difference can be directly deducted from the target account, which is not limited here.

[0077] In the embodiment of this specification, before recharging the power source, the user can submit a power source recharging application to the server to report the power source recharging in advance, and after the application is approved, the power source recharging can be performed through the identification code. The specific implementation process is as follows: receiving the power source recharging related information sent by the terminal device of the target user; verifying the power source recharging related information, and when the verification result is verification passed, granting the terminal device the authority to use the target identification code.

[0078] Specifically, the power source replenishment related information may include but is not limited to the target user information of the target user, the estimated replenishment station information for executing the power source replenishment, the power source type, and the estimated cost of the power source replenishment. The user's terminal device may run a transaction client corresponding to the server. Before the user executes the power source replenishment, the user may upload the power source replenishment plan through the transaction client, fill in the power source replenishment related information, and send it to the server.

[0079] Taking the example that power source replenishment associated information includes target user information and expected replenishment station information for executing power source replenishment, the process of verifying the power source supply associated information can be achieved through the following steps: based on the preset correspondence between user information and identification code, determine whether there is an identification code corresponding to the target user information; if so, use the identification code corresponding to the target user information as the identification code to be used, and determine the set replenishment station information corresponding to the identification code to be used; verify whether the expected replenishment station information is the same as the set replenishment station information, wherein, when the expected replenishment station information is the same as the set replenishment station information, it indicates that the verification of the power source supply associated information is successful.

[0080] Specifically, as described above, when assigning an identification code to a user, the user information of the user can be bound to the identification code, so that a preset correspondence relationship between the user information and the identification code can be established, and the preset correspondence relationship can be stored on the server. When the server receives the target user information sent by the target user, by searching the preset correspondence relationship, it can be known whether the target user information is assigned an identification code. If there is no identification code corresponding to the target user information, it means that the target user has not applied for the identification code, then the target user can be prompted to apply for the identification code, and the identification code application interface can be pushed to the target user. If there is an identification code corresponding to the target user information, the found identification code is used as the identification code to be used, that is, the power source replenishment transaction can be carried out through the identification code.

[0081] It should be noted that for each identification code, a respective refueling station can be set, that is, for an identification code, it can only be used at a designated refueling station and cannot be used at other refueling stations. In the embodiment of this specification, when configuring an identification code for each transaction card, corresponding set refueling station information can be assigned to each identification code, so that the correspondence between the identification code and the set refueling station information can be pre-established. Among them, the set refueling station information corresponding to different identification codes can be the same or different, which is not limited here. Based on the correspondence between the identification code and the set refueling station information, the set refueling station information corresponding to the identification code to be used can be determined.

[0082] Furthermore, the expected refueling station information submitted by the target user is compared with the set refueling station information corresponding to the identification code to be used. If the two are the same, it indicates that the power source supply related information verification has passed. If the two are different, it indicates that the user wants to use the identification code to conduct a power source supply transaction at a non-designated refueling station, which obviously does not meet the conditions for the use of the identification code, and the power source supply related information verification fails.

[0083] In the embodiment of this specification, when the power source supply associated information verification is passed, it indicates that the use of the identification code meets the use conditions, and at this time, the terminal device can be granted permission to use the target identification code. If the power source supply associated information verification fails, the target identification code is not authorized to be used. For example, when the terminal device sends a request to the server to present the target identification code, the server can refuse to send the target identification code to the terminal device for display, or the terminal device can present the target identification code, but the server can refuse to process the transaction operation corresponding to the target identification code.

[0084] In the embodiments of this specification, in order to facilitate the user to understand the usage of the transaction amount corresponding to the identification code, after verifying the power source replenishment related information, the unconsumed amount corresponding to the identification code to be used can also be determined, and the unconsumed amount can be fed back to the terminal device. Specifically, the transaction amount corresponding to the identification code to be used is allowed to be used multiple times. In order to facilitate the user to know the current available amount before each power source replenishment, the unconsumed amount corresponding to the identification code to be used can be sent to the terminal device.

[0085] In addition, considering that the identification code to be used determined based on the target user information and the preset correspondence between the user information and the identification code may be different from the target identification code. In order to prevent the target user from using the identification code applied for by other users, in the embodiment of this specification, it can be determined whether the target identification code is the identification code to be used; if so, it is determined whether the target refueling station information is the same as the set refueling station information, wherein when the target refueling station information is the same as the set refueling station information, the target account is deducted.

[0086] Specifically, if the target identification code is the same as the identification code to be used, it indicates that the target identification code is an identification code bound to the target user, and the target user can use the target identification code. Therefore, when the target supply station information for the current power source replenishment is the same as the set supply station information, the power source replenishment transaction can be carried out, and the target account is deducted based on the transaction amount. On the contrary, if the target identification code is different from the identification code to be used, it indicates that the target identification code is not an identification code bound to the target user, and at this time, the target user is prohibited from using the target identification code.

[0087] In summary, the transaction method provided in the embodiment of this specification associates the target identification code with the target account, and the target account can be operated by scanning the target identification code, eliminating the complex and time-consuming manual reimbursement process and improving the account management efficiency of vehicle power source replenishment. At the same time, when the transaction amount exceeds the transaction limit of the target identification code, the difference can be paid by the target user instead of the target account, ensuring the security of the target account.

[0088] Based on the same inventive concept, the embodiment of this specification provides a transaction method, which is applied to a server, such as Figure 2 As shown, the method comprises the following steps:

[0089] Step S21: After the power source refueling of the vehicle is completed, receiving order information sent by the payment terminal of the target refueling station by scanning the target identification code, wherein the target identification code is an identification code associated with the target account, and the order information includes the transaction amount corresponding to the power source refueling and the target transaction amount corresponding to the target identification code;

[0090] Step S22: when the transaction amount is greater than the target transaction amount, deducting the target transaction amount from the target account; and

[0091] Step S23: determining the difference between the transaction amount and the target transaction amount, generating payment information based on the difference, and feeding back the payment information to the payment terminal so that the target user can perform a payment operation.

[0092] In the embodiment of this specification, the server generates payment information based on the difference and feeds the payment information back to the payment terminal, so that the payment terminal performs subsequent transactions based on the payment information. Regarding the above method, its specific implementation method is similar to the embodiment of the transaction method described above, and will not be elaborated here.

[0093] Based on the same inventive concept, the embodiment of this specification provides a method for obtaining an identification code, which is applied to a terminal device, and the terminal device can be a user's mobile phone, tablet computer, etc. Figure 3 As shown, the method comprises the following steps:

[0094] Step S31: sending an identification code application request for a target account to a server providing identification code services;

[0095] Step S32: when the target user of the terminal device is an unregistered user, completing user registration based on the registration interface provided by the server, so that the server associates the target identification code with the target user;

[0096] Step S33: receiving the target identification code sent by the server, so that after the power source of the vehicle is refueled, the payment terminal of the target refueling station sends order information to the server by scanning the target identification code;

[0097] The order information includes the transaction amount corresponding to the power source replenishment and the target transaction amount corresponding to the target identification code; when the transaction amount is greater than the target transaction amount, the server deducts the target transaction amount from the target account associated with the target identification code, and determines the difference between the transaction amount and the target transaction amount.

[0098] It should be noted that the server providing the identification code service can be the same server as the server providing the payment service to the user and the refueling station, or of course, they can be different servers.
