Description
Technical field
The present invention relates to computing machine and communication technical field, relate in particular to a kind of offline transaction method, a kind of offline transaction system, a kind of point of sales terminal and a kind of background server based on point of sales terminal based on point of sales terminal.
Background technology
Electronic payment mode is compared with traditional pay-us-you-go plan, has advantages of without small change, and the risk of can evade cash loss simultaneously, sneak into counterfeit money, cash being robbed, is therefore accepted by people soon, becomes one of consumption pattern of current main flow.
Pay Payment Card, mobile phone wallet and the point of sales terminal (POS, Point-Of-Sale terminal) that conventionally need to hold by means of users such as stored-value card, bank cards by mails.Hold the user of Payment Card or mobile phone wallet when consumption, by POS terminal, read card number or the identification informations such as user ID corresponding to mobile phone wallet of Payment Card, the transaction related informations such as the consumption amount of money of this transaction, time of origin and the identification-information reporting that reads are settled accounts to background server.
The implementation of existing E-Payment mainly contains on-line transaction and two kinds of modes of offline transaction, and its ultimate principle is as follows:
(1) on-line transaction mode:
The schematic flow sheet of accompanying drawing 1 for adopting on-line transaction mode to pay by mails, existing bank card adopts on-line transaction mode to pay by mails conventionally.
Step 101, after user card punching, POS terminal sends on-line transaction request to background server, carries the transaction data such as the card number of the Payment Card reading and the authorization informations such as password of user's input and the dealing money of this transaction, exchange hour in this on-line transaction request;
Step 102, background server is according to the card number carrying in the on-line transaction request receiving, in the corresponding relation of the password of inputting when the card number of storing from database and registration, the password of inputting while finding registration corresponding to described card number, when the password finding is consistent with the password carrying in on-line transaction request, by checking, enter step 103;
Step 103, background server extracts transaction data from on-line transaction request, and preserves the transaction data extracting;
Step 104, background server sends on-line transaction response to POS terminal, this Transaction Success of notice POS terminal;
Step 105, POS terminal receives after on-line transaction response, stores the transaction data of this transaction;
When follow-up other user card punchings are paid by mails, circulation execution step 101～step 105;
Step 106, POS terminal is when every day, the predetermined clearing time arrived, according to the transaction data of storage, calculate the dealing money sum and the total stroke count of transaction of each transaction after clearing last time, and the dealing money sum calculating is carried in clearing request and sends to background server with the total stroke count of transaction;
Step 107, background server carries out reconciliation processing, be whether the dealing money sum that in comparison step 106, POS terminal is sent is consistent with the dealing money sum of extracting from each on-line transaction request receiving after clearing last time, and whether transaction stroke count sum corresponding to each on-line transaction request of receiving after clearing of the total stroke count of the transaction that in step 106, POS terminal is sent and last time be consistent, when dealing money and transaction stroke count are all consistent, determine reconciliation success, otherwise reconciliation failure;
Step 108, background server, when reconciliation success, sends clearing response to POS terminal, reconciliation of notice POS terminal success;
Step 109, the transaction data of POS terminal deletion storage on the same day.
(2) offline transaction mode:
The schematic flow sheet of accompanying drawing 2 for adopting offline transaction mode to pay by mails, existing mass transit card, mobile phone wallet adopt offline transaction mode to conclude the business conventionally.
Step 201, POS terminal and background server carry out alternately, carry out the processing of registering, and obtain a batch sign from background server;
Step 202, after user card punching (or mobile phone wallet), the transaction data of POS terminal storage card number (or user ID) and this transaction;
When follow-up other user card punchings are paid by mails, circulation execution step 202;
Step 203, when POS terminal receives the tally order that operating personnel input by modes such as buttons, calculation procedure 201 carry out register process after the dealing money summation of N transaction of storage, and by step 201 carry out register process after the transaction data of N transaction of storage, batch sign that the dealing money summation calculating and the total stroke count N of transaction and step 201 obtain is carried in clearing request, send to background server;
Step 204, background server carries out reconciliation processing, from clearing request, extract each transaction data, whether the dealing money sum of each transaction of calculate the extracting transaction stroke count corresponding with dealing money summation transaction data whether consistent and that extract in clearing request be consistent with the total stroke count N of transaction settling accounts in asking, if dealing money is all consistent with transaction stroke count, enter step 205;
Step 205, background server sends to POS terminal by clearing response, and notice POS terminal is settled accounts successfully;
Step 206, after POS terminal is known and settled accounts successfully, deletes the transaction data of the N transaction of storage;
Step 207, POS terminal sends to background server the message of registering again, and the processing of next time registering obtains next batch sign, follow-up repeated execution of steps 202～step 206.
Adopt mobile phone wallet to pay by mails and adopt bank card to pay by mails to compare, user inputs password when carrying card, memory cipher and concluding the business, simplified user's operation, simultaneously because user ID is all to adopt system of real name registration conventionally, thereby there is higher security, therefore obtained universal fast.
When yet the offline transaction mode shown in employing Fig. 2 is paid by mails, tend to exist following problem:
In the process of execution step 203～step 206, because POS terminal and the mutual mass data of background server can take certain hour, and the restriction due to POS terminal processing capacity, the transaction data that in step 206, POS terminal is checked the N ' transaction in transaction data and the clearing responses of N transaction of self storage also can take the more time, therefore at present conventionally the data upload time in step 203 is set in to the moment before leaving offices operating personnel, in order to avoid affect user, pays by mails.Yet due to the quantitative limitation of POS terminal storage, when the transaction data of storage approaches or arrive the memory space upper limit of POS terminal and owing to now not arriving the predetermined data upload time, thereby POS terminal be cannot empty the transaction data of storage time, POS terminal cannot be paid by mails more normally.While generally running into this situation, POS terminal can imperative operation personnel be settled accounts, perform step 203～step 206, before the transaction data of the N transaction of storing at POS terminal deletion, cannot pay by mails, the stand-by period that this will inevitably increase user, affect follow-up electric payment transaction.

Embodiment
In existing POS terminal, the transaction data of many transactions adopts the mode of queue in log file, as shown in Figure 3, a plurality of steps in accompanying drawing 2 all relate to the operation to log file, for example, relate to during step 201 store transactional data log file is carried out to " writing " operation; During step 203 uploading data, need to carry out to log file " reading " operation; When deleting transaction data, step 206 need to carry out deletion action to log file.
Inventor finds in existing offline transaction process, occur that user cannot pay by mails when execution step 203～step 206, thereby causing period of reservation of number, long (transaction data of uploading that cannot simultaneously perform step 203～step 206 correspondence is processed, and step 201 correspondence is paid processing by mails) reason be that existing POS terminal only has the POS terminal synchronization that an instruction parser causes can only carry out an instruction, and the log file that stores transaction data can only be performed an operation at synchronization, otherwise there will be read/write conflict problem.
For the problems referred to above, inventor has proposed a kind of for carrying out the POS terminal of offline transaction, linux operating system is installed to support multi-threaded parallel operation, at least two log files is set simultaneously in POS terminal and in order to rotation, stores the transaction data of the E-Payment of current generation.The implementation of two log files of take is example: after start, first the transaction data that storage is concluded the business at every turn in the first log file, when meeting data upload condition, select content and continue the transaction data of the transaction of the current generation of storage for the second empty log file is used for replacing the first log file, and the transaction data of N the transaction of storing in the first log file is sent to background server, execution step 203～step 206; Until while again meeting data upload condition, the transaction data of M the transaction of storing in the second log file is sent to background server, perform step 203 steps 206, so move in circles, thereby the executed in parallel that realizes store transactional data and transmission transaction data, has solved the long problem of period of reservation of number in prior art.
Below in conjunction with each accompanying drawing, embodiment of the present invention technical scheme main realized to principle, embodiment and the beneficial effect that should be able to reach is explained in detail.
As shown in Figure 4, to realize principle process as follows for the embodiment of the present invention main:
To, according to foregoing invention principle of the present invention, introduce in detail an embodiment the main principle that realizes of the inventive method is explained in detail and is illustrated below.
Accompanying drawing 5a is the principle schematic of existing POS terminal, and the resolver on hardware layer is inferior can only support synchronization can only carry out an instruction; Accompanying drawing 5b is the principle schematic of the POS terminal of the embodiment of the present application proposition, by the (SuSE) Linux OS on hardware level, supports two above instructions of executed in parallel.
The detail flowchart of the method for commerce that accompanying drawing 6 provides for the embodiment of the present invention, wherein stores at least two blank log files in POS terminal, the form of each log file is still similar to existing log file in accompanying drawing 3.
Step 601, POS terminal powers on after start, carries out alternately with background server, carries out the processing of registering, and obtains a batch sign from background server;
Be specially: POS terminal sends to background server by the request of registering that carries equipment of itself sign, background server is carried at a batch sign of distributing to this POS terminal in the response of registering and feeds back to POS terminal.
Step 602, it is that the first log file in empty log file is for writing the transaction data of current transaction that POS terminal is selected at least two contents;
Step 603, POS terminal writes at every turn the swipe the card transaction data of the E-Payment correspondence implemented of user after start in the first log file;
Step 604, judges whether to receive user by the tally order of the clearing key-press input in POS terminal, if enter step 610, otherwise enters step 605;
Step 605, POS terminal is when meeting the condition of predetermined uploading data, from at least two log files, selecting next content is that empty log file is as the second log file, enter concurrently step 606 and step 607, now the content of the first log file and the second log file is as shown in accompanying drawing 7a;
Preferably, the condition of the predetermined uploading data in step 605 is " residual memory space writing in the log file (being the first log file here) of transaction data is less than predetermined value ", and for example the residual memory space in the first log file is less than 1MByte, 500KByte; Or
" timing length of the uploading data timer of arrive setting ", for example, set at interval of within 2 hours, uploading a secondary data; Or
" receive user by the upper teletype command of uploading key-press input on POS terminal panel ";
Or " receive the upper teletype command that background server sends ", please refer to shown in accompanying drawing 8, described background server is divided into all POS terminals that connect the group of predetermined number, for every group of POS terminal set the corresponding uploading data time, between the POS terminal of different groups, the time of uploading data is different, for example background server is divided into 6 groups by 30 POS terminals that connect, each group comprises 5 POS terminals, 1 o'clock every afternoon, to the POS terminal of the first group, sent teletype command, 2 o'clock every afternoons, to the POS terminal of the second group, sent teletype command, the rest may be inferred.Can make by this method the time of POS terminal uploading data stagger, avoid due to most POS terminals network congestion problem that all uploading data causes in 1,2 hour after before leaving offices.
It should be noted that, pre-conditioned in step 605 can be also above-mentioned several pre-conditioned combinations, no matter, when that condition of this combination meets, all can trigger to background server and send the transaction data in the first log file.For example pre-conditioned is " residual memory space of the first log file is less than predetermined threshold and and arrives predetermined timing length ", predetermined timing length is within every 4 hours, to upload a secondary data, when POS terminal is comparatively idle, as the POS terminal in the supermarket morning or on weekdays the time period in the afternoon, according to every 4 hours, uploading a secondary data can meet the demands completely, but in the comparatively busy time period in the afternoon at weekend, the first log file will be occupied full very soon, in the time of should being less than predetermined threshold at the residual memory space of the first log file so, trigger uploading data, rather than wait until when predetermined timing length arrives just uploading data.Other situations pre-conditioned or pre-conditioned combination are also similar, here give an example no longer one by one.
Step 606, POS terminal sends to background server by the transaction data of storing in the first log file, enters step 608;
POS terminal can increase check bit when sending transaction data in the message sending, so that background server is determined correctness and the integrality of the transaction data receiving according to check bit.
Background server correctly intactly receives after the transaction data that described POS terminal sends determining, preserves the transaction data that the described POS terminal that receives is sent.
Step 607, is stored in transaction data corresponding to each E-Payment occurring after step 605 in the second log file that step 605 selects, and returns to step 604;
Step 608, receive after the notification message that background server successfully receives the data that write in complete reception first log file of POS terminal feedback in step 606, according to the transaction data in described the first log file, accumulation calculating goes out corresponding transaction total charge and the total stroke count of transaction of transaction data having sent, and enters step 609;
For example, in the first log file as shown in accompanying drawing 7a, there are 4 transaction records: transaction record 1～transaction record 4.Wherein the dealing money of transaction record 1 is that 10 yuan, the dealing money of transaction record 1 are that 15 yuan, the dealing money of transaction record 1 are that 50 yuan, the dealing money of transaction record 4 are 100 yuan, transaction total charge corresponding to transaction data having sent is 175 yuan, and total stroke count of concluding the business is 4.
Step 609, POS terminal empties the transaction data in the first log file, returns to step 604;
Now the content of the first log file and the second log file is as shown in accompanying drawing 7b, wherein three transaction data in log file 2 be after step 604, the transaction data of the E-Payment correspondence that occurs before step 609.The first log file again can be upper while once meeting the condition of predetermined uploading data after emptying, and selected being adopted as a child renews the transaction data of the current transaction of storage.
Step 610, when POS terminal receives the tally order of user by the key-press input on POS terminal panel, after the current transaction total charge and clearing last time writing in the transaction data of storing in the log file of transaction data, and receive the transaction total charge sum of the transaction data having sent in the described tally order time period before as clearing total charge, using current writing the total stroke count of transaction that the transaction data stored in the log file of transaction data is corresponding with the total stroke count sum of transaction of the transaction data having sent as the total stroke count of clearing, enter step 611,
Conventionally user settled accounts before coming off duty.
Preferably, after last time clearing and the transaction total charge and the total stroke count of concluding the business that receive the transaction data having sent in the time period before described tally order obtain in the following manner:
In can POS terminal, a counter being set is used for to the transaction total charge of the transaction data having sent and always than number, adds up, in above-mentioned steps 608, receive after the notification message of the data that write in complete reception first log file of background server feedback corresponding transaction total charge and the total stroke count of transaction of transaction data that uses this counter accumulation calculating to go out to have sent at every turn.The zero clearing after receiving clearing success response of this counter, registers and processes rear startup in execution; Or
Alternatively, in step 608, without accumulation calculating, go out corresponding transaction total charge and the total stroke count of transaction of transaction data having sent, but storage now transaction total charge and the total stroke count of transaction (at every turn sending to corresponding transaction total charge and the total stroke count of transaction of transaction data of background server) of the transaction data in (step 609 empty before) first log file, after receiving tally order, transaction total charge corresponding to the transaction data that at every turn sends to background server of storage and the total stroke count of transaction are sued for peace, after determining front lump-sum settlement, transaction total charge and the total stroke count of transaction of the transaction data of background server before these clearing, have been sent to.
Now in current the second log file that is writing transaction data, there are three transaction records, corresponding dealing money is all 10 yuan, so now the transaction total charge of the second log file is 30 yuan, the total stroke count of transaction of the second log file is 3, the correspondence transaction total charge of the transaction data before having sent is 175 yuan, the correspondence of the transaction data having sent total stroke count of concluding the business is 4, and therefore settling accounts total charge is 205 yuan, and settling accounts total stroke count is 7.
Step 611, POS terminal sends to background server by carrying the current clearing request that is writing the transaction data of storing in the log file of transaction data, the clearing total charge of determining and settling accounts total stroke count, enters step 612;
Step 612, background server receives after clearing request, after clearing last time, the transaction data comprising in the transaction data that this POS terminal is sent and clearing requests and settle accounts total charge and settle accounts total stroke count and carry out reconciliation processing, and after reconciliation success, to described POS terminal, send clearing success response;
Reconciliation process is specially: after background server calculates clearing last time, dealing money sum in each transaction data that the terminal of POS described in step 606 is sent adds that whether the result of the transaction total charge in the transaction data comprising in clearing requests is consistent with the clearing total charge comprising in clearing request, and whether the result of the total stroke count of transaction that the transaction stroke count sum in the transaction data sent of the terminal of POS described in step 606 adds the transaction data comprising in clearing request is with to settle accounts the total stroke count of clearing comprising in asking consistent;
Dealing money sum in calculating each transaction data that described POS terminal sends add the transaction stroke count sum in the transaction data that described in the result of transaction total charge of the transaction data comprising in clearing request and step 606 consistent with the clearing total charge comprising in clearing request, POS terminal is sent add the transaction data comprising in clearing request the total stroke count of transaction result with settle accounts the total stroke count of clearing comprising in asking when consistent, determine reconciliation success, otherwise determine reconciliation failure;
For example, background server is before receiving clearing request, store 4 transaction data that in the accompanying drawing 7a that in step 606, POS terminal is sent, the first log file comprises, after receiving clearing request, from clearing request, extract 3 transaction data that in the accompanying drawing 7b comprising, the first log file comprises, the dealing money that calculates 4 transaction data of storage is 205 yuan with the dealing money sum of 3 transaction data that extract, consistent with the clearing total charge comprising in clearing request, illustrate that the clearing total charge that dealing money sum in each transaction data that described POS terminal sends adds that the result of dealing money of the transaction data of each transaction comprising in clearing request comprises in asking with clearing is consistent, and the stroke count of the transaction data of storage is 4, the stroke count of the transaction data extracting is 3, sum of the two is 7, also consistent with 7 of the total stroke counts of clearing that comprise in clearing request, reconciliation success is now described.
Step 613, POS terminal, after receiving the clearing success response that background server sends, empties the transaction data in the file that writes transaction data, and at this moment the first log file and the second log file are all null file, return to step 601, wait for the processing of next time registering.
Preferably, after in step 612, background server can be determined clearing last time according to the time that receives the transaction data that described POS terminal sends, the transaction data that this POS terminal is sent, accuracy and promptness while determining the clearing last time transaction data that this POS terminal is sent afterwards in order further to improve background server, when in step 608, POS terminal sends to background server by message by the transaction data of storing in the first log file, can also in this message, carry batch sign that step 601 obtains, when background server receives the message that comprises transaction data that carries batch sign, the corresponding relation of the transaction data comprising in storage batch sign and this message, when step 612 is settled accounts, only need to be according to batch sign in clearing request, from the transaction data of having stored, find corresponding batch sign and batch transaction data that sign is consistent of settling accounts in asking, after settling accounts the transaction data finding as last time, the transaction data that this POS terminal is sent.
In the POS terminal that the embodiment of the present invention provides, safeguard and have at least two log files, one of them log file is for storing the transaction data of the E-Payment correspondence of the current enforcement of swiping the card.When pre-conditioned, meet, in the time of need to sending the transaction data writing in a log file to server, forbid writing transaction data in this log file, can only in another log file of selecting, write transaction data, after transaction data in this log file has been cleared, this log file allows to be reselected to write the transaction data of current transaction.Thereby when sending the transaction data such as dealing money of each transaction of having stored to network side, still can pay by mails, and without only writing after transaction data in the log file of transaction data sends to background server and complete clearing, just can pay by mails, shorten the stand-by period.Preferably, for example, for fear of meeting the condition of predetermined uploading data when (residual memory space that is writing the log file of transaction data is less than predetermined value), because also not emptied in time, the transaction data in another one log file cannot do not reselected out in order to continue to write the transaction data of current transaction, the mode that can adopt a plurality of log file wheels to turn, please refer to shown in accompanying drawing 9, 5 log file wheels turn, before the transaction data in the first log file is sent to background server, be chosen in the second log file relaying and continue the transaction data into current transaction, in the time the transaction data in the second log file need to being sent to background server, be chosen in the 3rd log file relaying and continue the transaction data into current transaction, ..., in the time the transaction data in the 5th log file need to being sent to background server, be chosen in the first log file relaying and continue the transaction data into current transaction, in this case as long as the first log file was cleared before the transaction data in the 5th log file is sent to background server.
In above-described embodiment step 605～step 609, by from upload a transaction data log file to server until delete the swipe the card transaction data of the E-Payment correspondence implemented of user in time period of the transaction data in this log file and be stored in another log file at every turn, rather than as prior art as long as wait for and could to process E-Payment next time after unique log file is cleared, thereby shortened the time of user's wait.
In addition, the method of commerce that the embodiment of the present invention provides, transaction data corresponding to all E-Payments occurring between twice clearing is divided into and repeatedly sends to respectively background server, rather than transaction data corresponding to all E-Payments that (normally before leaving offices after 1,2 hour) occurs between by twice clearing in regular time every day section as prior art once issued background server, realize the technique effect of equalising network load, avoided occurring in the short time network congestion situation.
Correspondingly, the embodiment of the present invention also provides a kind of point of sales terminal, and as shown in figure 10, this device comprises the first determining unit 110, writing unit 120, the first transmitting element 130 and empties unit 140, specific as follows:
The first determining unit 110, for the process that the transaction data of current transaction is write to the first log file at writing unit 120, monitor and meet when pre-conditioned, using another log file except the first log file as the second log file, the content of described the second log file is empty;
The first transmitting element 130, for determining after the second log file in the first determining unit 110, sends to background server by the transaction data writing in described the first log file;
