The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention, and in the absence of conflict, the present invention The embodiments and the features in the embodiments can be combined with each other.

The smart card involved in the embodiment of the present invention can be a patch card, a card embedded in an NFC terminal, or a standard bank card and other forms, of course not limited to the above forms, any card that can carry data information Both are available.

Embodiment one

As shown in Figure 1, it is a schematic diagram of the implementation process of implementing the data processing method on the network server side, including the following steps:

S101. The network side server receives the first data clearing request sent by the POS terminal (point of sale) terminal;

During specific implementation, the first data clearing request carries a unified user identifier, which is acquired by the POS terminal from the smart card.

S102. The server on the network side modifies the data state corresponding to the unified user identifier to a state to be cleared;

S103. The server on the network side sends a data clearing instruction to the POS terminal;

During specific implementation, after receiving the data clearing request, the network side server assembles the clearing script, and carries the clearing script in the data clearing instruction returned to the POS terminal.

S104, if the data clearing result returned by the POS terminal is received, judge whether the data clearing is successful according to the data clearing result, if yes, perform step S105, otherwise, perform step S106;

S105. The server on the network side clears the locally stored data quantity corresponding to the unified user identifier;

S106. The network side server modifies the data state corresponding to the unified user identifier to a normal state.

During specific implementation, the first data clearing request received by the server on the network side may also carry the amount of data to be cleared, which is obtained by the POS terminal from the smart card.

During specific implementation, in order to solve the problem that the network side server cannot receive the data clearing result returned by the POS terminal within a certain period of time due to network delays and other reasons, resulting in a processing bottleneck, the network side server can according to the feedback from the POS terminal, according to The following two ways are handled:

Method 1: The server on the network side receives the second data clearing request sent by the POS terminal

Wherein, the data clearing request carries a unified user identifier and a second data quantity to be cleared, and the second data quantity to be cleared is reacquired by the POS terminal from the smart card. In this case, the server on the network side can handle it in the following manner: the server on the network side acquires the data status corresponding to the unified user ID recorded locally; If the data status is waiting to be cleared, send the data clearing command to the POS terminal again; if the second number of data to be cleared is zero and the data status corresponding to the unified user ID is waiting to be cleared, clear the locally stored data corresponding to the unified user ID .

Method 2: The server on the network side receives the data clearing and revocation request sent by the POS terminal

In this case, the network side server may modify the data state corresponding to the unified user identifier to a normal state.

During specific implementation, after the network-side server completes the data clearing operation, specifically, after the network-side server clears the locally stored data corresponding to the unified user ID, it needs to interact with a third-party server to perform a data transfer operation. Among them, the data transfer operation may include the following steps:

Step 1. The server on the network side sends a data transfer request to the third-party server;

The data transfer request carries a unified user identifier and the amount of data to be transferred, wherein the amount of data to be transferred is the same as the first amount of data to be cleared.

Step 2. The server on the network side modifies the data state corresponding to the unified user ID to a transfer state;

Step 3, the network side server receives the data transfer success message or the data transfer failure message returned by the third-party server;

Step 4. If the data transfer success message is received, the server on the network side modifies the data status corresponding to the unified user ID to a logout status, and returns a confirmation message that the data transfer is successful to the POS terminal;

Step 5. If the data transfer failure is received, return a confirmation message of the data transfer failure to the POS terminal.

During specific implementation, if the data transfer fails, the network side can also send a data transfer request to the third-party server again, and return a confirmation message of data transfer failure to the POS terminal after the data transfer fails again.

During specific implementation, if the POS terminal does not receive the confirmation message of data transfer success or data transfer failure returned by the network side server within a specified period of time, in order to ensure the security of data processing, in the embodiment of the present invention, the network side server according to the POS The feedback from the terminal can be processed in the following two ways:

Mode 1: The server on the network side receives the third data clearing request sent by the POS terminal

Wherein, the third data clearing request carries a unified user identification and a third data quantity to be cleared, and the third data quantity to be cleared is when the POS terminal does not receive a confirmation message of successful or failed data transfer within a specified time period , re-obtained from the smart card. In this case, the server on the network side can handle it in the following manner: the server on the network side obtains the locally recorded data status corresponding to the unified user ID, if the third data to be cleared is zero and the current data status of the local Status, return a confirmation message of successful data transfer to the POS terminal; if the third data to be cleared is zero and the current data status of the local record is transfer status, judge whether the data transfer is successful; when the judgment result is yes, the locally recorded The data state corresponding to the unified user identifier is modified to a logout state; when the judgment result is no, a data recovery request is sent to a third-party server, and the data recovery request carries the first data quantity to be cleared; after receiving the data recovery success After the message, send the data transfer request to the third-party server again, wherein the data recovery success message is sent after the third-party server recovers data according to the first data quantity to be cleared.

Method 2: The server on the network side receives the data clearing and revocation request sent by the POS terminal

In this case, the server on the network side can handle it according to the following steps:

Step 1. The network side server judges whether the data transfer is successful, and if the judgment result is yes, execute step 2, otherwise execute step 4;

Step 2, the server on the network side sends a data recovery request to the third-party server;

During specific implementation, the data recovery request carries the first amount of data to be cleared.

Step 3. After receiving the data recovery success message returned by the third-party server, the network side server modifies the data state corresponding to the unified user ID to a normal state, and the process ends;

Wherein, the data restoration success message is sent by the third-party server after restoring data according to the first data volume to be cleared.

Step 4. Modify the data state corresponding to the unified user identifier to a normal state.

Embodiment two

Embodiment 2 describes the implementation flow diagram of the POS terminal side data processing method in the data processing process, as shown in Figure 2, may include the following steps:

S201. The POS terminal acquires the unified user identification of the smart card and the amount of data to be cleared;

S202. The POS terminal sends a data clearing request to the network side server;

Wherein, the data clearing request sent carries the acquired unified user ID and the amount of data to be cleared;

S203. The POS terminal receives the data clearing instruction sent by the server on the network side;

During specific implementation, the clearing script is carried in the data clearing instruction.

S204. The POS terminal forwards the data clearing instruction to the smart card;

During specific implementation, after receiving the data clearing instruction, the smart card clears the data stored in itself, and returns the data clearing result to the POS terminal.

S205. If the POS terminal receives the data clearing result, forward the data clearing result to the network side server.

During specific implementation, after receiving the data clearing result sent by the POS terminal, if the network side server determines that the data clearing is successful according to the data clearing result, it will send a data transfer request to the third-party server, and after the data transfer process is completed, send a data transfer request to the third party server. The POS terminal returns a confirmation message of success or failure of data transfer.

During the specific implementation, in the above process, the POS terminal may not receive the data clearing result returned by the smart card or the confirmation message of the success or failure of the data transfer sent by the server on the network side within the specified time period. At this time, the POS terminal can Prompt the user whether to clear the data again. If the user chooses No, the POS terminal will obtain the data amount of the smart card again. If the amount of data obtained is zero, the process can be ended directly; The server sends a data clearing cancellation request; if the user selects Yes, the POS terminal needs to resend the data clearing request to the network side server again.

Embodiment Three

In order to better understand the embodiment of the present invention, the method for processing the balance in the electronic cash account during the process of canceling the account of the electronic cash wallet is taken as an example to describe the embodiment of the present invention. In practical applications, due to the need for data processing procedures, there is also a POS terminal front-end system (POSP, POS terminal Proxy) between the POS terminal and the server on the network side. In the embodiment of the present invention, the POSP does not process the received data, but only forwards it.

As shown in Figure 3, it is a schematic diagram of the implementation process of processing the balance in the electronic cash account during the process of canceling the electronic cash account, including the following steps:

S301. The POS terminal accepts the user's account cancellation application;

S302. The POS terminal reads the smart card information;

The user puts the smart card close to the POS terminal, and the POS terminal reads the smart card information, including the co-branded card number and the balance of the electronic cash account, where the co-branded card number is the unified card number of the user's credit account, debit account and electronic cash account.

S303. The smart card returns the card number and electronic cash account balance;

S304. The POS terminal will send a data clearing request to the POSP;

Wherein, the obtained card number and electronic cash account balance are carried in the data clearing request.

S305. The POSP forwards the data clearing request to the network side server;

S306. The server on the network side authenticates the electronic cash account, and when the authentication passes, modifies the electronic cash account to the state to be cleared, and assembles a balance clearing script;

During specific implementation, if the authentication fails, a response message of authentication failure will be returned to the POS terminal through the POSP.

S307. The network side server sends a data clearing instruction to the POSP;

The zero-clearing script is carried in the data clearing command.

S308. The POSP forwards the data clearing instruction to the POS terminal;

S309. The POS terminal forwards the data clearing instruction to the smart card;

S310. The smart card returns a data clearing response message;

Wherein, the data clearing response message can be either a message of successful data clearing or a message of data clearing failure. Return to the POS terminal a message that data clearing is successful, otherwise return a message that data clearing fails.

S311. The POS terminal sends a data clearing result to the POSP;

S312. The POSP forwards the data clearing result to the network side server;

S313. When the network side server determines that the data clearing is successful according to the data clearing result, continue to execute step S314, otherwise, the network side server changes the status of the electronic cash account to a normal status;

S314. The network side server deducts the balance in the electronic cash account stored by itself;

Through this step, the network side server clears the balance in the electronic cash account stored by itself.

S315. The server on the network side sends a data transfer request to the third-party server;

Specifically, the network side server carries the card number and balance in the data transfer request;

S316. The third-party service transfers the balance to the credit account corresponding to the card number;

S317. The third-party server returns the data transfer result to the network side server;

S318. If the data transfer is successful, the server on the network side modifies the status of the electronic cash account to a canceled status;

S319. The network side server returns the data transfer result to the POSP;

S320. The POSP forwards the data transfer result to the POS terminal;

S321. The POS terminal displays a data transfer result.

Embodiment Four

In the specific implementation, due to network quality and other reasons, data processing exceptions may occur during the process of data clearing and data transfer. The terminal fails to respond within the specified time period, resulting in the inability to process the electronic cash account cancellation application normally. In order to solve this problem, in the embodiment of the present invention, the following methods can be used for processing: when the POS terminal does not respond for a long time, the user can be prompted whether to perform data clearing and data transfer operations again. According to the user's choice, there can be the following two situations, such as As shown in FIG. 4, it is a schematic diagram of the data processing flow when the data processing is abnormal. The normal processing steps shown in FIG. Let me repeat.

S421. Prompting the user whether to initiate data clearing and data transfer operations again;

Depending on the user's choice, there are two possible situations:

1. If the user selects Yes, the data clearing and data transfer operations will be performed again

In this case, as shown in Figure 4, the following two steps may also be included:

Step 1. Print the operation failure ticket;

Step 2. Re-initiate the data clearing operation.

2. If the user chooses No, the data clearing and data transfer operations will no longer be performed

In this case, as shown in Figure 4, the following steps may also be included:

Step 1. Print the operation failure ticket;

Step 2. The POS terminal reads the balance of the smart card electronic cash account;

Step 3, the smart card returns the electronic cash account balance;

Step 4. The POS terminal judges whether the balance is 0. If it is 0, the process can be ended directly; if it is not 0, go to step 5;

Step 5, the POS terminal sends a data clearing and revocation request to the POSP;

Step 6, POSP forwards the data clearing and revocation request to the network side server;

Step 7. The server on the network side modifies the status of the electronic cash account to a normal status;

Step 8. The server on the network side sends an electronic cash account balance confirmation message to the third-party server;

Step 9. If the third-party server confirms that the data transfer operation has been performed, restore the balances of the electronic cash account and the credit account respectively;

Step 10, the third-party server returns a confirmation result to the network side server;

Step 11, the network side server returns a confirmation result to the POSP;

Step 12. The POSP forwards the confirmation result to the POS terminal.

During specific implementation, if the user selects Yes, that is, when the data clearing and data transfer operations are reinitiated, the balance of the electronic cash account of the smart card may be inconsistent with the balance of the electronic cash account of the server on the network side due to the data and data transfer operations performed for the first time before. There may also be multiple possibilities for the status of the electronic cash account recorded by the side server. For example, 1) if an abnormality occurs in steps S308 and S309 and the POS terminal does not respond due to timeout, because the smart card has not received the data clearing command, the smart card electronic cash account The balance is not 0, and the status of the electronic cash account recorded by the server on the network side is pending clearing; 2) If an exception occurs in step S310 and the POS terminal does not respond due to timeout, since the NFC has received the data clearing command and cleared the electronic cash account stored by itself Balance, at this time, the balance of the smart card electronic cash account is 0, and the status of the electronic cash account recorded by the network side server is pending clearing; 3) If any abnormality occurs in steps S315 to S317, the network side server cannot return data to the POS terminal The result of the transfer results in no response from the POS terminal overtime. At this time, the balance of the smart card electronic cash account is 0, and the status of the electronic cash account recorded by the server on the network side is pending clearing; 4) If an abnormality occurs in step S320 and the POS terminal does not respond after timeout , since the NFC has received the data clearing instruction and cleared the balance of the electronic cash account stored by itself, and the network side server has sent a data transfer request to the third-party server, at this time, the balance of the smart card electronic cash account is 0, and the electronic cash account recorded by the network side server The status of the cash account is canceled;

Based on this, in the embodiment of the present invention, re-initiating data clearing and data transfer operations can be processed according to the balance of the smart card electronic cash account and the status of the electronic cash account recorded by the network side server, which will be introduced separately below.

22. systems as claimed in claim 21, is characterized in that,

Described POS terminal, when the data also returned for not receiving described smart card in appointment duration empty result, whether prompting carries out data null clear operation again; No longer carry out data if receive when emptying instruction, again obtain the data bulk of described smart card, if the data bulk again obtained is zero, process ends; If the data bulk again obtained is non-vanishing, sends data to described network side server and empty the request of cancelling;

Described network side server, also for after receiving data that described POS terminal sends and emptying the request of cancelling, is revised as normal condition by data mode corresponding for described unification user mark.

23. the system as claimed in claim 22, is characterized in that,

Described POS terminal, if also for receive again carry out data empty instruction time, send the second data to described network side server and empty request;

Described network side server, after the second data also sent for receiving described POS terminal empty request, obtains the data mode that the described unification user mark of local record is corresponding; If the second data bulk to be emptied is non-vanishing and described unification user identifies corresponding data mode for treating empty, again send data flush instructions to described POS terminal; If described second data bulk to be emptied is zero and described unification user identifies corresponding data mode for treating empty, empty the data bulk of local that store, described unification user mark correspondence.

24. systems as described in claim 22 or 23, is characterized in that, also comprise third-party server, wherein:

Described network side server, also for after emptying data bulk corresponding to local that store, described unification user mark, data transfer request is sent to described third-party server, carry described unification user mark and data bulk to be transferred in described data transfer request, described data bulk to be transferred is identical with described first data bulk to be emptied; And data mode corresponding for described unification user mark is revised as transfering state; If data batchmove success, to the confirmation message that described POS terminal return data transfer is successful, and data mode corresponding for described unification user mark is revised as exit state; If data batchmove failure, to the acknowledge message that described POS terminal return data transfer is failed;

Described POS terminal, also in appointment duration, when receiving the data batchmove success of described network side server transmission or failed acknowledge message, process ends.

25. systems as claimed in claim 24, is characterized in that,

If described POS terminal is also in appointment duration, when not receiving the data batchmove success of described network side server transmission or failed acknowledge message, whether prompting carries out data null clear operation again; Receive and no longer carry out data when emptying instruction, again obtain the data bulk of described smart card; If the data bulk again obtained is zero, process ends; If the data bulk again obtained is non-vanishing, sends data to described network side server and empty the request of cancelling;

Described network side server, also for receiving after described data empty the request of cancelling, judges data batchmove whether success; If, data recovery request is sent to third-party server, the first data bulk to be emptied is carried in described data recovery request, after receiving the date restoring success message that described third-party server returns, data mode corresponding for described unification user mark is revised as normal condition, and described date restoring success message is send after described third-party server recovers data according to described first data volume to be emptied; If not, data mode corresponding for described unification user mark is revised as normal condition;

Described third-party server, also for after the data recovery request receiving the transmission of described network side server, recovers data according to described first data bulk to be emptied; And after date restoring success, be successfully recovered message to described network side server return data.

26. systems as claimed in claim 25, is characterized in that,

Described POS terminal, if also for receive again carry out data empty instruction time, send the 3rd data to described network side server and empty request, described 3rd data empty in request and carry described unification user mark and the 3rd data bulk to be emptied;

Described network side server, also for after receiving the 3rd data and emptying request, obtains the data mode that the described unification user mark of local record is corresponding; If the 3rd data bulk to be emptied is zero and the current data state of local record is exit state, to the confirmation message that described POS terminal return data transfer is successful; 3rd data bulk to be emptied is zero and the current data state of local record is transfering state, judges that whether data batchmove is successful; If so, data mode corresponding for the described unification user mark of local record is revised as exit state; If not, send data recovery request to third-party server, carry the first data bulk to be emptied in this data recovery request and recover data; And after receiving date restoring success message, again send data transfer request to third-party server;
