Some block diagrams shown in the drawings are functional entitys, not necessarily must be with physically or logically independent entity phase It is corresponding.These functional entitys can be realized using software form, or in one or more hardware modules or integrated circuit in fact These existing functional entitys, or these functions reality is realized in heterogeneous networks and/or processor device and/or microcontroller device Body.

To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, and reference Attached drawing, the present invention is described in more detail.

Acquirer in Fig. 1 refers in bank's card payment transactions as business processing side, is engaged in the developing of franchised business Movable with management, authorization requests, billing settlement etc., interests are mainly derived from other service charges of trade company's return commission, trade company's payment (such as POS machine rent, monthly fee) and merchant deposit increase, and can be realized the request processing side for receiving single business in addition to most of hairs Block bank (i.e. receipts uniline), there are also non-banking professional services organizations.

Transaction backstage functions only as transparent transmission role in transaction flow shown in FIG. 1, the result of transaction and rushes positive result all It is to rely on POS machine to report, and update database positioning.In addition, always by the core in transaction in entire transaction flow, i.e., Order status is stored in POS machine side, but since POS machine is to be chronically exposed in public network, and the safety of public network is poor, It is highly susceptible to criminal's attack, so that criminal has an opportunity to distort the order status that POS machine records, is traded Safety it is poor.

Fig. 2 shows a kind of flow chart of the transaction communications method provided in one embodiment of the disclosure, this method is for trading Server in system, that is, transaction backstage.Method includes the following steps:

As shown in Fig. 2, in step s 201, receiving the transaction request from POS machine, wherein the transaction in the present embodiment is asked It asks as the credit card transaction in response to POS machine and triggers.

As shown in Fig. 2, transaction request is sent to request processing side in step S202.

As shown in Fig. 2, receiving the response message that simultaneously cache request processing side returns in step S203.

As shown in Fig. 2, in step S204, the state of information update credit card transaction according to response.

It should be noted that in request stage, (namely POS machine issues request and clothes to server in the present embodiment Business device sends the requests to the stage of request processing side), server can still act as transparent transmission role, but response phase (also It is that request processing direction server issues response message and response message is sent to the stage of POS machine by server), server The role of transparent transmission response message is no longer acted only as, but the Response information cache received is got off, " request " here refers to Transaction request and the positive request of punching, " response message " refer to transaction response data and rush positive response data.Go out in the following embodiments Existing transaction return packet be exactly characterization transaction whether successful response data, punching just return packet is exactly characterization rush just whether successfully response Data.

Process is it is found that POS machine initially enters transactional stage after carrying out credit card transaction triggering, if transaction according to Fig. 1 Stage POS machine does not receive packet of trading back and then triggers into next stage, that is, rushes the positive stage.Therefore, in transactional stage, above-mentioned step The rapid received response message of S203 is packet of trading back, and the Bao Shi that trades back represents whether request processing policy successfully hands over transaction request Easy returns packet.

In the present embodiment, Fig. 3 shows the flow chart after step S203, comprising the following steps:

As shown in figure 3, the packet that will trade back is sent to POS machine, if POS machine does not receive packet of trading back in step S301 Transaction Inquiries request is then triggered, then carries out step S302.Although server receives the transaction that request processing side returns and returns after packet, The packet that can will trade back is sent to POS machine, but due to the influence of communication conditions, POS machine, which there may be, can not receive packet of trading back The case where, it is therefore desirable to POS machine actively carries out Transaction Inquiries to server.

As shown in figure 3, in step s 302, server is requested in response to Transaction Inquiries, packet is returned into the transaction of caching and is sent To POS machine.It is sent to POS machine it is, will trade back to wrap by server, to inform transaction results to trade company, trade company Know whether the result of this credit card transaction succeeds.

This method is first inquired in the case where not receiving and trading back packet, and is inquired and can constantly be retried, if logical Cross inquire and retry inquiry can receive trade back packet can complete trade, do not need to rush again just, so as to reducing rush just Rate.

Based on above-mentioned steps S301, POS machine issues Transaction Inquiries to server according to certain query strategy and requests, at this In embodiment, query strategy can be poll, that is, (such as 1 minute) is inquired always in one section of preset time, until receiving Packet is returned in the transaction that server returns.But if when the query strategy of Transaction Inquiries request fails (namely within a preset time Do not receive packet of trading back by repeatedly inquiring yet) after, POS machine do not receive yet trade back packet when, then triggered by POS machine and issue punching Positive request, that is, enter and rush the positive stage.

In the present embodiment, due to the influence of communication conditions, rushing the positive stage further includes two kinds of situations: the first situation, punching Positive request does not issue；Second situation does not receive corresponding time packet although the positive request of punching successfully issues, at this point, The packet that returns for rushing the positive stage is just returning packet for punching, and punching is just returning Bao Shi and representing whether the positive request that liquidates of request processing policy successfully rushes positive time Packet.

Fig. 4 shows the step flow chart in the case where rushing positive request in the present embodiment without issuing, comprising the following steps:

As shown in figure 4, POS machine repeats to issue the positive request of punching within a preset period of time, until server in step S401 Receive the positive request of punching.

As shown in figure 4, after server receives the positive request of punching, the positive request of punching is then forwarded at request in step S402 Reason side.

As shown in figure 4, request processing policy generates corresponding rush to the positive request of this punching and is just returning packet in step S403, And it is sent to server.

As shown in figure 4, in step s 404, server is just returning the state that packet updates credit card transaction according to punching, and will rush just It returns packet and is sent to POS machine, inform so that positive result will be rushed to trade company, trade company, which is known, rushes whether positive result succeeds.

Fig. 5 shows the step process for rushing in the present embodiment and just requesting successfully to issue but not receiving in the case that packet is just returned in punching Figure, comprising the following steps:

As shown in figure 5, POS machine rushes positive inquiry request to server sending, that is, is rushed and just looked into step S501 It askes, similar to the process of Transaction Inquiries.

As shown in figure 5, server rushes positive inquiry request in response to POS machine in step S502, rushing for caching is just returned Packet is sent to POS machine, informs to rush positive result to trade company, trade company, which is known, rushes whether positive result succeeds.

It will not trade back to wrap or rush because of accidentally primary communication conditions influence POS machine reception in the present embodiment and just return packet, and It is first to carry out Transaction Inquiries and the positive inquiry of punching later confiscating, and is to inquire repeatedly, exception can be greatly lowered in this way Customer Complaint caused by order brings good experience of swiping the card for customer.

The case where packet is just being returned in punching is not received still for rushing just to request successfully to issue, and can also use following scheme:

Server waits the positive request of punching next time, and rushing for caching is just returned packet and be sent in response to rushing positive request next time POS machine.Since general POS machine can carry out rushing just automatically, so even rushing this time is just returned Bao Wei and received, needle is also had Swipe the card to this rush it is positive rush positive request and issued from POS machine, server can will equally rush the positive packet that returns and issue POS machine, It informs so that positive result will be rushed to trade company, trade company, which is known, rushes whether positive result succeeds.

It should be noted that in step S404 server will punching just returning the step of packet is sent to POS machine if it fails, its Subsequent processing just requests successfully to issue the processing scheme not received still in the case that packet is just being returned in punching referring to for rushing, herein no longer It repeats.

It should also be noted that, in the present embodiment server also to trading back packet and punching is just being returned the ciphertext of packet and parsed, And by the transaction results after parsing and rush positive result and cache, in this way, the result entirely traded not existing scheme one for another example Sample relies on POS machine and reports, but is subject to the result of server oneself backstage caching.Result with existing scheme transaction is with public affairs It is compared subject to the result that POS machine in net reports, the method in the present embodiment can prevent transaction results from being distorted by people's malice, from And improve the safety of transaction.

Fig. 6 shows the method in the present embodiment in the interaction schematic diagram of entire transaction flow.

As shown in fig. 6, POS machine triggers credit card transaction in transactional stage, transaction request is sent to server (in Fig. 6 Indicated with transaction backstage), transaction request is sent to request processing side, request by transaction backstage in a manner of ciphertext transparent transmission of trading again Processing side, which will trade back to wrap again, is sent to transaction backstage, and transaction backstage caches packet of trading back, and according to the transaction in packet of trading back As a result database positioning is updated.Transaction backstage, which will also trade back to wrap, is sent to POS machine, if POS machine does not receive the Bao Ze that trades back Into inquiry phase, Transaction Inquiries are carried out.

POS machine to transaction backstage issue inquiry request, and query strategy failure before using poll by the way of one periodically Interior to retry repeatedly, transaction backstage, which will trade back to wrap, is sent to POS machine.

If arriving query strategy, POS machine still do not receive packet of trade back, then is causing and rushing just, into rushing the positive stage.If handed over Easily backstage does not receive the positive request of punching, then POS machine retries always transmission, rushes positive request until issuing.If transaction backstage has been received To the positive request of punching, but POS machine does not receive corresponding punching and is just returning packet, then enters inquiry phase, inquired, be similar to transaction Rushing for caching is just returned packet and is sent to POS machine by inquiry, transaction backstage；Or transaction backstage waits the positive request of punching next time, and rings Ying Yu rushes positive request next time and just returns packet and be sent to POS machine rushing for caching.

In conclusion transaction communications method provided in this embodiment is by returning in server side cache request processing side Packet is returned, (i.e. transaction backstage) is updated for the state of transaction is no longer the result that reports according to POS machine so that server, but Be subject to the state of server buffer, can real-time update, such businessman can also learn the state of transaction in time, because of order exception Caused the rate of complaints is greatly reduced.By being improved to interactive process, reduces rush positive rate as far as possible, but inquiring repeatedly The case where all having no resolution undershoot just also improves as far as possible and rushes positive success rate.

Fig. 7 shows a kind of schematic diagram of the server provided in another embodiment of the disclosure, which is exactly transaction system Entire process of exchange is completed with POS machine and request processing side in transaction backstage in system jointly.As shown in fig. 7, server 700 Including communication module 710, cache module 720 and update module 730.

Wherein communication module 710 is configured to receive the transaction request from POS machine and transaction request is sent to request Processing side, wherein transaction request triggers for the credit card transaction in response to POS machine.In simple terms, communication module 710 is exactly to complete Communication between server and POS machine and request processing side 730.Cache module 720 is configured to receive and cache request is handled The response message just returned, in place of this is also the main distinction of the server and existing scheme in the present embodiment, i.e., server is not Transparent transmission role is functioned only as, but is cached during returning and trading back and wrap or rush and just returning packet.Update module 730 configures For the transaction results according to the state of response message update credit card transaction, therefore in the present embodiment or rush just the result is that with server Subject to the updated state of middle update module 730.

In the present embodiment, communication module has both sides effect, first is that interacting with POS machine, that is, receives POS machine The transaction request of transmission and the positive request of punching, and trade back to wrap and rush to POS machine return and just returning packet；Second is that with request processing side into Row interaction sends transaction request and the positive request of punching to request processing side, and receive the transaction that request processing side returns and return packet Packet is just being returned with punching.

Fig. 8 shows the schematic diagram of the communication module in another embodiment of the disclosure.In the present embodiment, transactional stage service What device received that request processing side returns return packet for packet of trade back, the Bao Shi that trades back representative request to handle policy to transaction request whether Packet is returned in Successful Transaction.As shown in figure 8, communication module 710 includes: trade back packet sending module 711 and transaction inquiry module 712, packet sending module 711 of trading back, which is configured to trade back to wrap, is sent to POS machine.Transaction inquiry module 712 is configured to work as POS Machine do not receive trade back packet and trigger Transaction Inquiries request when, in response to Transaction Inquiries request, by the transaction of caching return packet send To POS machine.By the inquiry of POS machine, server, which will trade back to wrap, is sent to POS machine, to inform transaction results to trade company, Trade company knows whether the result of this credit card transaction succeeds.Query strategy can be poll, that is, in one section of preset time (such as 1 minute) is inquired always, and packet is returned in the transaction until receiving server return.

It by the way that transaction inquiry module is arranged, is first inquired in the case where not receiving and trade back and wrap, and inquiry can be with Constantly retry, if by inquiry and retry inquiry can receive trade back wrap can complete trade, do not need to rush again just, from And it can reduce and rush positive rate.

When the query strategy failure of Transaction Inquiries request (does not namely receive friendship by repeatedly inquiring within a preset time yet Easily return packet) after, POS machine does not receive yet when trade back packet, trigger by POS machine and issues punching and just requested, i.e., into rushing the positive stage.

Rushing the positive stage further includes two kinds of situations: the first situation, rushes positive request and does not issue；Second situation, punching are just asked It is successfully issued although asking, does not receive corresponding return and wrap, at this point, the packet that returns for rushing the positive stage is just returning packet for punching, rushed and just return Bao Shi representative request processing policy, which liquidates, just requests whether successfully to rush positive time packet.

As shown in figure 8, communication module 710 further includes rushing positive request receiving module 713, it is configured to not receive punching when server When positive request, POS machine repeats to issue the positive request of punching within a preset period of time, until server receives the positive request of punching.It is namely logical It crosses and retries repeatedly, the positive request of punching can be received to ensure to rush positive request receiving module 713, then the positive request of punching is then forwarded to and is asked Processing side is asked, request processing policy generates corresponding rush to the positive request of this punching and just returning packet, and is sent to server.Server is again The state that packet updates credit card transaction is just being returned according to punching, and packet is just being returned into punching and is being sent to POS machine, is being informed so that positive result will be rushed to quotient Family, trade company, which is known, rushes whether positive result succeeds.

As shown in figure 8, communication module 710 further includes rushing positive enquiry module 714, it is configured to just ask when server receives punching It asks, but POS machine does not receive punching when just returning packet, rushes positive inquiry request in response to POS machine, rushing for caching is just returned packet and be sent to POS machine.

Positive enquiry module is rushed by setting, first carries out Transaction Inquiries and the positive inquiry of punching later confiscating, and be repeatedly Inquiry, can be greatly lowered Customer Complaint caused by abnormal order in this way, bring good experience of swiping the card for customer.

As shown in figure 8, communication module 710 further includes waiting rushing positive module 715, it is configured to just ask when server receives punching It asks, but POS machine does not receive punching when just returning packet, waits the positive request of punching next time, and will caching in response to rushing positive request next time Rush and just return packet and be sent to POS machine.

It is entirely trading the result is that be subject to server oneself backstage caching result, with existing scheme transaction result with It is compared subject to the result that POS machine in public network reports, the present embodiment can prevent transaction results from being distorted by people's malice, to improve The safety of transaction.

In addition, in the server in modules without reference to function retouched referring to the correlation in above method embodiment It states, details are not described herein again.

As shown in Figure 10, it in step S1001, is triggered in response to credit card transaction and issues transaction request.

As shown in Figure 10, in step S1002, the response message returned to server inquiry request processing side, wherein taking Business device is cached with response message.

In request stage, (namely POS machine issues request to server and server sends the requests to request processing The stage of side), server can still act as transparent transmission role, but (namely request processing direction server issues in response phase Response message is sent to the stage of POS machine by response message and server), server no longer acts only as the angle that transparent transmission returns packet Color, but the Response information cache received is got off, " request " here refers to transaction request and the positive request of punching, " response message " Refer to trade back to wrap and rush and is just returning packet.

In transactional stage, POS is packet of trading back from the received response message of server, and the Bao Shi that trades back represents request processing Policy to transaction request, whether wrap by returning for Successful Transaction.

In the present embodiment, Figure 11 shows flow chart after step S1001, comprising the following steps:

As shown in figure 11, it in step S1101, trades back packet if POS machine does not receive and triggers Transaction Inquiries request, and Transaction Inquiries request is sent to server.Although server receives the transaction that request processing side returns and returns after packet, can will hand over It easily returns packet and is sent to POS machine, but due to the influence of communication conditions, POS machine, which there may be, can not receive the case where trading back packet, Therefore it needs POS machine actively to issue Transaction Inquiries request to server and carries out Transaction Inquiries.

As shown in figure 11, in step S1102, POS machine receives the friendship that server is requested in response to Transaction Inquiries and returned Packet is returned, easily so that trade company knows whether the result of this credit card transaction succeeds.

By step shown in Figure 11, POS machine is first inquired in the case where not receiving and trading back packet, and inquiring can Constantly to retry, if by inquiry and retry inquiry can receive trade back wrap can complete trade, do not need to rush again just, Positive rate is rushed so as to reduce.

In step S111, POS machine issues Transaction Inquiries to server according to certain query strategy and requests, in this implementation In example, query strategy can be poll, that is, (such as 1 minute) is inquired always in one section of preset time, until receiving service Packet is returned in the transaction that device returns.But if the query strategy failure when Transaction Inquiries request (namely passes through within a preset time Repeatedly inquiry do not receive packet of trade back yet) after, POS machine do not receive yet trade back wrap when, then by POS machine trigger rush just request, i.e., Into rushing the positive stage.

In the present embodiment, after the positive request of triggering punching, due to the influence of communication conditions, rushing the positive stage further includes two kinds of feelings Condition: the first situation is rushed positive request and is not issued；Second situation does not receive although the positive request of punching successfully issues Corresponding to return packet, at this point, the packet that returns for rushing the positive stage is just returning packet for punching, punching, which is just returning Bao Shi and represents request and handle policy, to liquidate positive request Positive returning whether is successfully rushed to wrap.

Figure 12 shows the step flow chart that the positive stage is rushed in the present embodiment, comprising the following steps:

As shown in figure 12, in step S1201, if POS machine does not issue the positive request of punching successfully, POS machine is default It repeats to issue the positive request of punching in period, be issued successfully until rushing positive request.Later, it after server receives the positive request of punching, will rush Positive request is then forwarded to request processing side；Request processing policy generates corresponding rush to the positive request of this punching and is just returning packet, and sends To server；Server is just returning packet according to punching and is updating database positioning, and packet is just being returned in punching and is being sent to POS machine, and POS machine is according to receipts To rush and just return packet and know and rush whether positive result succeeds.

As shown in figure 12, in step S1202, if POS machine has successfully issued the positive request of punching, but punching is not received just Packet is returned, then POS machine, which is triggered and issued, rushes positive inquiry request, that is, carries out rushing positive inquiry, similar to the process of Transaction Inquiries.? In the present embodiment, POS machine sends Transaction Inquiries request using the query strategy of poll and rushes positive inquiry request.

As shown in figure 12, in step S1203, POS machine receives server in response to rushing positive inquiry request and rushing for returning Packet is just being returned, is rushing whether positive result succeeds to know.

The positive request of punching has successfully been issued for POS machine, but has not received the case where packet is just being returned in punching, can also have been used as follows Scheme:

POS machine receives server and waits the positive request of punching next time, and in response to rushing positive request rushing caching just next time Return packet.Since general POS machine can carry out rushing just automatically, so even rushing this time is just returned Bao Wei and received, needle is also had Swipe the card to this rush it is positive rush positive request and issued from POS machine, punching equally can just returned packet and issue POS machine, POS by server Machine, which receives to rush just to return to wrap, rushes whether positive result succeeds to know.

It should be noted that the positive request of above-mentioned steps punching is in first time without issuing successfully and issuing by repeatedly retrying Later, server will punching just returning the step of packet is sent to POS machine if it fails, its subsequent processing referring to for rush positive request at Function issues but does not receive the processing scheme in the case that packet is just returned in punching, and details are not described herein again.

POS machine receives transaction return in the present embodiment or punching is just returned before packet, and server is also wrapped to trading back and rushed just The ciphertext for returning packet is parsed, and by the transaction results after parsing and is rushed positive result and cached, in this way, the result entirely traded Existing scheme does not rely on reporting for POS machine equally for another example, but be subject to server oneself backstage caching result.With it is existing The result of scheme transaction is subject to the result that the POS machine in public network reports and is compared, and the method in the present embodiment can prevent from trading As a result it is distorted by people's malice, to improve the safety of transaction.

In conclusion transaction communications method POS machine provided in this embodiment into server query service device by caching The response message that returns of request processing side so that server (i.e. transaction backstage) is no longer according to POS for the state of transaction The result that machine reports updates, but be subject to the state of server buffer, can real-time update, such businessman also can be timely The easy state of bosom friend, because order extremely caused by the rate of complaints be greatly reduced.In transactional stage, POS machine repeats inquiry and trades back Packet, can reduce and rush positive rate.But enter in the case where inquiring and all having no resolution repeatedly and rush the positive stage, do not have in the positive request of primary punching It is also to retry in the case where sending repeatedly, improves rush positive success rate as far as possible.
