Obviously, for ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0020] The purpose, features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Specific implementation method

[0021] It should be understood that the specific embodiments described herein are only used to explain the technical solution of the present application and are not used to limit the present application.

[0022] In order to better understand the technical solution of this application, the following will be described in detail in conjunction with the accompanying drawings and specific implementation methods.

[0023] The main solution of the embodiment of the present application is: after detecting the physical card through the NFC module, read the first transaction record data in the physical card; send the first recharge application instruction to the background system based on the first transaction record data, so that the background system builds the card transaction record and sends the recharge instruction to the recharge application; receive the recharge instruction sent by the background system, and send the recharge instruction to the physical card through the NFC module; if the execution result returned by the physical card is received within the preset first time, the recharge is successful; if the execution result returned by the physical card is not received within the preset first time, perform a secondary data reading and comparison on the physical card, and if the comparison is successful, the recharge is successful.

[0024] In this embodiment, for the convenience of description, the following description is based on the recharge system as the execution subject.

[0025] In the field of transportation, physical transportation cards are used to read data and change balances through instructions. During the card recharge process, after the backend issues a recharge instruction (balance change instruction), the recharge instruction execution result may not be received due to reasons such as card movement. At this time, the backend order status is in the recharge (this patent calls it a gray transaction) state. In this case, the physical card may have been successfully recharged or may not have been successfully recharged, requiring manual intervention and verification, resulting in high operation and maintenance costs.

[0026] In addition, current technology can determine whether the recharge is successful by the change in the card balance before and after recharge, but this simple balance judgment has defects. Because in the case of a gray transaction order, the card can also change the balance through consumption transactions generated by riding, recharging, etc. If the gray transaction order is actually recharged successfully, and then the same recharge amount is consumed, the balance after consumption is consistent with the card balance before recharge. Judging whether the gray transaction is recharged successfully only by the balance, the conclusion is that the recharge failed, which is obviously a misjudgment and causes financial losses to the card company.

[0027] This application provides a solution. In this application, if the recharge application receives the execution result returned by the physical card within the preset first time, the recharge is successful; if the recharge application does not receive the execution result returned by the physical card within the preset first time, the physical card is read and compared for the second time, thereby determining whether the gray transaction is successfully recharged, thereby avoiding manual intervention and verification, and reducing operation and maintenance costs.

[0028] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device, a recharge device, etc. that can realize the above functions, or an electronic system, a recharge system, etc. that can realize the above functions. The following takes the recharge system as an example to illustrate this embodiment and the following embodiments.

[0029] Based on this, the present application embodiment provides a recharge method, refer to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the recharge method of this application.

[0030] In this embodiment, applied to a recharge application, the recharge method includes steps S20 to S60: Step S20, after the physical card is detected by the NFC module, reading the first transaction record data in the physical card; Wherein, the recharge application can be installed on a mobile terminal, such as a mobile phone.

[0031] Optionally, the recharge application includes an NFC module to implement the NFC function.

[0032] When the card balance of the physical card is changed, a card transaction record will be written synchronously in the card, so the recharge application can read the first transaction record data in the physical card through the NFC module.

[0033] The first transaction record data may include information such as the physical card number, balance, transaction time, transaction amount, and transaction location.

[0034] As an implementation method, due to the limited storage space of the physical card, the first transaction record data can store limited transaction records. For example, the first transaction record data can be 10 transaction records, and the new transaction will overwrite the oldest transaction record.

[0035] Step S30, sending a first recharge application instruction to the background system based on the first transaction record data, so that the background system constructs a card transaction record and sends a recharge instruction to the recharge application; After receiving the request, the backend system will create a card transaction record in the database to track the status and details of the recharge.

[0036] Step S40, receiving the recharge instruction sent by the background system, and sending the recharge instruction to the physical card through the NFC module; It should be noted that the balance information needs to be updated in the physical card at this time.

[0037] Step S50, if the execution result returned by the physical card is received within the preset first time, the recharge is successful; Among them, the preset first time can be set based on the actual situation, which will not be described here.

[0038] Step S60: If the execution result returned by the physical card is not received within the preset first time, the physical card is read and compared for the second time. If the comparison is successful, the recharge is successful.

[0039] It should be noted that the recharge application may not receive the recharge instruction execution result due to reasons such as the physical card moving or the physical card not receiving the recharge instruction. In this case, the physical card needs to be read and compared for the second time.

[0040] This embodiment provides a recharge method. In this application, if the recharge application receives the execution result returned by the physical card within the preset first time, the recharge is successful; if the recharge application does not receive the execution result returned by the physical card within the preset first time, the physical card is read and compared for the second time, thereby determining whether the gray transaction is successfully recharged, thereby avoiding manual intervention and verification, and reducing operation and maintenance costs.

[0041] Based on any of the above embodiments, in the second embodiment of the present application, the same or similar contents as the above embodiments can refer to the above introduction, and will not be repeated later. On this basis, in step S20, after the physical card is detected by the NFC module, before the first transaction record data in the physical card is read, the recharge method also includes step S10: Step S10, in response to the recharge operation, sending a creation order instruction and a payment instruction to the backend system, so that the backend system creates an order and completes the payment operation.

[0042] It should be noted that users can use a mobile phone with NFC function, install the recharge application and enter the physical card recharge function, select the recharge amount and complete the payment. At this time, the recharge application sends the creation order instruction and payment instruction to the background system. After receiving the creation order instruction and payment instruction, the background system creates the order and completes the payment operation.

[0043] ​It should be noted that at this point the user has paid, which has been recorded in the recharge app and the backend system, but has not been synchronized to the physical card.

[0044] If Figure 2 As shown, Figure 2 This is a flowchart of the recharge method for this application Figure 1 .

[0045] After payment, open the card recharge page of the recharge application, use the physical card to stick to the back of the phone, and after the recharge application detects the card through the NFC module, it sends an instruction to read the card number, balance and 10 transaction records in the card, and sends the first recharge application instruction to the background system based on the transaction record data, so that after receiving the first recharge application instruction, the background system registers 10 transaction records in the card, including transaction sequence number, transaction time, transaction amount, transaction device number, etc.

[0046] The embodiment of this application designs a complete recharge process to ensure the reliability of the operation and user experience.

[0047] Based on any of the above embodiments, in the third embodiment of the present application, the same or similar contents as the above embodiments can refer to the above description, and will not be repeated later. On this basis, step S60, if the execution result returned by the physical card is not received within the preset first time, the secondary data reading and comparison of the physical card also includes steps S61~S62: Step S61, if the execution result returned by the physical card is not received within the preset first time, and the movement of the physical card is detected by the NFC module, the user is guided to re-attach the card; Among them, the user can be guided to re-attach the card through voice prompts, screen displays, indicator light prompts, vibration feedback, etc.

[0048] Among them, you can refer to Figure 3 , Figure 3 This is a flowchart of the recharge method for this application Figure 2 .

[0049] When the backend system sends a recharge instruction to the recharge application, and the recharge application sends a recharge instruction to the physical card, the result is unknown because the physical card has been moved. At this time, an exception occurs in the recharge application, the process is interrupted, and the recharge application guides the user to re-attach the card. When the recharge application detects that the user has re-attached the card through the NFC module, it sends an instruction to the physical card to perform a secondary data read and comparison on the physical card, including reading the card number, balance, and 10 transaction records in the card.

[0050] Step S62, performing secondary data reading and comparison on the physical card.

[0051] Among them, the secondary data reading and comparison of the physical card may include reading the second transaction record data in the physical card; sending a second recharge application instruction to the background system based on the second transaction record data, so that the background system compares the second transaction record data with the first transaction record data and / or the card transaction record.

[0052] The embodiment of the present application improves the user experience and recharge success rate through mechanisms such as real-time feedback, operation guidance, secondary data reading and comparison.

[0053] Based on any of the above embodiments, in the fourth embodiment of the present application, the same or similar contents as those in the above embodiments can be referred to the above description, and will not be repeated in the following. On this basis, step S62, performing secondary data reading and comparison on the physical card also includes steps S621~S622: Step S621, reading the second transaction record data in the physical card; Please refer to Figure 3 , read the second transaction record data in the physical card including the card number, balance and 10 transaction records in the card.

[0054] Step S622: Send a second recharge application instruction to the background system based on the second transaction record data, so that the background system compares the second transaction record data with the first transaction record data and / or the card transaction record.

[0055] As an implementation method, the backend system may compare the second transaction record data with the first transaction record data.

[0056] As another implementation, the backend system may compare the second transaction record data with the card transaction record data.

[0057] As another implementation method, the backend system may first compare the second transaction record data with the first transaction record data, and if the comparison is successful, the second transaction record data is compared with the card transaction record.

[0058] Reference Figure 4 , the recharge application sends a second recharge application instruction to the background system, so that the background system registers 10 transaction records in the card in the previously created card transaction record, including transaction sequence number, transaction time, transaction amount, transaction device number, etc., so that the background system compares the second transaction record data with the first transaction record data and / or card transaction record.

[0059] The embodiment of the present application can effectively determine whether the recharge order is successful by comparing the second transaction record data with the first transaction record data and / or the card transaction record, thereby avoiding manual intervention and reducing operation and maintenance costs.

[0060] In the fifth embodiment of the present application, a recharge method is also proposed, which is applied to the background system. The method includes steps S11~S12: Step S11, receiving a first recharge application instruction sent by the recharge application based on first transaction record data, and constructing a card transaction record, wherein the first transaction record data is obtained by reading the physical card after the recharge application detects the physical card through the NFC module; It should be noted that this embodiment is applied to the backend system, and the backend system receives the first recharge application instruction sent by the recharge application based on the first transaction record data, wherein the first transaction record data may include information such as the physical card number, balance, transaction time, transaction amount, and transaction location.

[0061] After receiving the request, the backend system will create a card transaction record in the database to track the status and details of the recharge.

[0062] Step S12, sending a recharge instruction to the recharge application, so that the recharge application sends the recharge instruction to the physical card through the NFC module. If the recharge application receives the execution result returned by the physical card within the preset first time, the recharge is successful. If the recharge application does not receive the execution result returned by the physical card within the preset first time, the physical card is read and compared for the second time. If the comparison is successful, the recharge is successful.

[0063] After constructing the card transaction record, the backend system sends a recharge instruction to the recharge application, so that the recharge application sends the recharge instruction to the physical card.

[0064] This embodiment provides a recharge method. In this application, if the recharge application receives the execution result returned by the physical card within the preset first time, the recharge is successful; if the recharge application does not receive the execution result returned by the physical card within the preset first time, the physical card is read and compared for the second time, thereby determining whether the gray transaction is successfully recharged, thereby avoiding manual intervention and verification, and reducing operation and maintenance costs.

[0065] Based on any of the above embodiments, in the sixth embodiment of the present application, the same or similar contents as those in the above embodiments can refer to the above introduction, and will not be repeated in the following. On this basis, you can refer to Figure 5The backend system includes an order payment system and a card management system. The receiving recharge application sends a first recharge application instruction based on the first transaction record data, and constructing a card transaction record includes steps S111 to S115: Step S111, checking the order status of the target order through the order payment system; Step S112: if the order status is the first recharge in a recharge transaction, obtaining the first transaction record data based on the first recharge application instruction through the order payment system; When the recharge application successfully reads the card information, it sends a recharge application instruction to the order payment system. After receiving the recharge application instruction, the order payment system checks the order status. If the order is the first card recharge, it will register the transaction record in the card, find the last transaction record according to the serial number, and record the card information before recharge.

[0066] It should be noted that in a recharge transaction, the first time the physical card is attached to the card is recorded as the first recharge in the recharge transaction. If the physical card is removed and then attached to the card again, it will be recorded as the second recharge in the recharge transaction, and so on.

[0067] It should be noted that by checking whether the physical card is the first recharge in a recharge transaction, the transaction record in the card before the recharge can be read, and data comparison can be performed based on the transaction record in the card before the recharge.

[0068] Step S113, sending a recharge application to the card management system through the order payment system, so that the card management system constructs a first recharge record and updates the first recharge record to a gray transaction state; Step S114, generating the recharge instruction through the card management system, and sending the recharge instruction to the order payment system, so that the order payment system sends the recharge instruction to the recharge application; After the first recharge information is successfully registered in the order payment system, the order payment system sends a recharge application instruction to the card management system. After the card management system receives the recharge application instruction, it constructs the first recharge record, updates the first recharge record to the gray transaction state, and generates and sends the recharge instruction to the order payment system.

[0069] Step S115, sending the card transaction data to the order payment system through the card management system, so that the order payment system updates the order status to the gray transaction status, and constructs the card transaction record based on the card transaction data.

[0070] After the order payment system receives the recharge instruction issued by the card management system, it updates the order status to the gray transaction status, and registers the transaction time, device number and other information issued synchronously by the card management system in the card transaction record.

[0071] The embodiment of the present application updates the order status of an unconfirmed order to a gray transaction status through the order payment system, which can ensure that the order can be correctly processed later and improve the stability and reliability of the recharge system.

[0072] Based on any of the above embodiments, in the seventh embodiment of the present application, the same or similar contents as those in the above embodiments can be referred to the above description, and will not be described in detail later. On this basis, the secondary data reading and comparison of the physical card, if the comparison is successful, the recharge is successful, including steps S121~S122: Step S121, receiving a second recharge application instruction sent by the recharge application through the order payment system, wherein the second recharge application instruction is sent by the recharge application based on the second transaction record data after reading the second transaction record data in the physical card; Among them, if the recharge application does not receive the card execution result within the preset first time, the process is interrupted, and the recharge application detects the card movement through the NFC module, and prompts the user to re-attach the card. After the user re-attaches the card, the recharge application re-reads the card balance and the transaction record in the card (the second transaction record data) through instructions, and re-initiates the second recharge application instruction to the order payment system based on the second transaction record data.

[0073] Step S122: The order payment system compares the second transaction record data with the first transaction record data and / or the card transaction record. If the comparison is successful, the recharge is successful.

[0074] For further information, please refer to Figure 5 , step S122 includes steps S1221~S1225: Step S1221, comparing the first transaction record data with the second transaction record data through the order payment system; If the order payment system determines that the order is not the first recharge, the last transaction record in the first transaction record data is matched with the second transaction record data.

[0075] Step S1222: if the comparison between the first transaction record data and the second transaction record data fails, the order status is updated to require manual verification; Among them, if the last transaction record in the first transaction record data cannot be matched in the second transaction record data, it means that the card has multiple other transactions after the recharge order gray transaction, and the original recharge order data may have been overwritten. It is unreliable to judge by the card transaction record, and the order status is updated to require manual verification.

[0076] Step S1223: if the first transaction record data and the second transaction record data are successfully compared, then the second transaction record and the card transaction record are compared; Among them, if the last transaction record of the first transaction record data can be matched in the second transaction record data, it means that if the record is not overwritten in the scenario where the gray transaction order is successfully recharged, the precondition has been met, and the transaction time, device number, and recharge amount information (i.e., card transaction record) issued by the order payment system through the card management system during the first recharge are matched with the second transaction record data.

[0077] Step S1224: if the second transaction record and the card transaction record are successfully compared, the order status is updated to recharge successful; If the second transaction record matches the card transaction record, it means that the recharge is successful, and the order status is updated to recharge successful; Step S1225: if the comparison between the second transaction record and the card transaction record fails, the order status is updated to recharge failure.

[0078] If the second transaction record does not match the card transaction record, it means that the recharge has failed, and the order status is updated to recharge failure. It is necessary to reapply for recharge again and execute step S114.

[0079] As an implementation method, a distributed blockchain network can also be built to record relevant data of all recharge transactions (such as transaction records, recharge instructions, status updates, etc.). Each node (such as order payment system, card management system, recharge application, etc.) participates in the maintenance and verification of the blockchain network. Specifically, in each recharge transaction, key data such as the first transaction record data, the second transaction record data, the recharge instruction, and the card transaction record are uploaded to the chain. The immutability of the blockchain can improve the security of the recharge process.

[0080] The embodiment of the present application can determine whether the gray transaction is successfully recharged through secondary data reading and comparison, thereby avoiding manual intervention and verification, and reducing operation and maintenance costs.
