Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

There are two limitations to current debit card swipe consumption: one is that the actual card swiping consumption may exceed the daily limit or each limit of the bank, so that the training course cost cannot be paid in full amount; another is that the debit card consumption is once credited to the account of the training institution, and if the training institution runs, the customer will have difficulty in recovering his own funds.

In view of the above, the invention provides a school fee supervision method capable of realizing batch credit and batch lap opening, namely after a customer agrees to pay and sign a contract for paying the school fee by a debit card, the school fee is frozen in the debit card of the customer, and a training institution periodically deducts the settlement money from the debit card of the customer. For the client, paying the school fee to ensure the fund safety; for a training institution, it is ensured that fees can be charged periodically to maintain operations. The method for supervising the charges of learning by carrying out the batch depositing and batch releasing can not only ensure the fund safety of the client, but also ensure the continuous and good operation of the training institution, and simultaneously can prevent the phenomenon that the training institution runs immediately after receiving a large amount of charges once, thereby achieving the purpose of supervising the charges of learning.

Referring to the system architecture diagram of the royalty monitoring system shown in fig. 1, the royalty monitoring system is composed of a monitoring front-end page, a monitoring background system and a core system; the monitoring front-end page and the monitoring background system adopt an ESSP (Education scene service platform) architecture and a BOCS (Bank of China system) architecture adopted by a core system. The supervision background system provides service for the supervision front-end page, and the off-line system and the on-line system are in background butt joint with the core system to achieve the function of payment of the toll. The training institution belongs to an external third party which is respectively communicated with the supervision front-end page and the supervision background system.

See figure 2 for a method flow diagram of the royalty administration method. The embodiment of the invention provides a method for supervising a toll, which is applied to a supervision background system and comprises the following steps:

and S10, determining that the payment of the debit card of the client is successful in signing the charge, wherein the successfully signed debit card has a binding relation with the charge amount of the target course.

In the embodiment of the invention, a client can select a training course, namely a target course, from the training structure APP, select a charge supervision payment mode, jump to a charge supervision payment page, read and sign a debit card charge guarantee contract. The customer uses the debit card to pay the school fee and must agree with a debit card school fee supervision protocol, after the customer signs the debit card school fee supervision protocol, the supervision background system checks whether the available balance of the customer debit card is more than or equal to the amount of the school fee to be paid, if so, the customer successfully signs the debit card school fee payment contract to ensure the subsequent payment of the school fee; if the charge amount is less than the predetermined value, the charge payment contract of the debit card of the client fails, the charge cannot be continuously paid, but the client can transfer the full amount to the debit card, and the contract can be continuously made.

In a specific implementation process, in step S10, "determining that the payment and sign of the debit card toll of the customer are successful" may adopt the following steps, and a flowchart of the method is shown in fig. 3:

s101, debit card information and certificate information uploaded by a client aiming at a target course are acquired.

S102, under the condition that the certificate information passes verification, judging whether the available balance of the debit card is more than or equal to the charge of the target course or not according to the debit card information; if yes, go to step S103.

S103, determining that the payment signing success of the debit card payment of the customer is successful.

In the embodiment of the invention, a client fills in debit card information and certificate information, wherein the debit card information comprises information such as a card number, an account opening person name and an account opening person identification number, and the certificate information comprises an identification card name, an identification card number and the like. The supervision background system firstly carries out certificate information verification, namely, whether the name of the identity card is matched with the identity card number or not, whether the name of an account issuer of the debit card is consistent with the name of the identity card or not, and whether the identity card number of the account issuer is consistent with the identity card number or not are verified; if the name of the identity card is matched with the number of the identity card, the name of an account issuer of the debit card is consistent with the name of the identity card, and the number of the identity card of the account issuer is consistent with the number of the identity card, the certificate information is determined to pass the verification; otherwise, if the name of the ID card is not matched with the ID card number, or the name of the account issuer of the debit card is not matched with the name of the ID card, or the ID card number of the account issuer is not matched with the ID card number, the certificate information verification is determined to be failed.

After the certificate information is verified, the supervision background system acquires the available balance of the debit card according to the card number of the debit card and judges whether the available balance of the debit card is more than or equal to the amount of the toll to be paid by the target course; if the charge is larger than or equal to the charge-collecting fee, determining that the charge-collecting fee subscription of the debit card of the customer is successful; otherwise, if the user's charge is less than the preset value, the user determines that the payment of the debit card payment of the client fails to sign the contract, and feeds back the result of the contract failure to the training mechanism.

And S20, based on the binding relationship, the amount of the school fee is charged from the available balance of the debit card through the core system.

In the embodiment of the invention, a customer agrees with a debit card charge-learning supervision protocol and uses a debit card for payment, the charge amount which the customer should pay is stored under the debit card of the customer, namely the charge amount is frozen under the debit card, the customer cannot use the charge amount, the available balance and the like of the debit card are reduced, the frozen amount and the like are increased, but the account balance of a training institution is kept unchanged.

In addition, the embodiment of the invention can complete the transfer of the amount of the school fee by one-time transfer. In the specific implementation process, after a customer completes debit card charge payment subscription, a supervision background system initiates a charge collection request to a core system in a socket mode, wherein the charge collection request comprises debit card information and charge amount; after receiving the charge collection request, the core system collects the charge amount from the available balance of the debit card, the charge amount is still under the debit card of the client, and only the available balance of the debit card is correspondingly reduced, the frozen amount is increased, and the client cannot use the charge amount in the subsequent process.

Subsequently, the core system feeds back the earmark result representing earmark success/failure to the supervision background system. The supervision background system outputs the earmark result to an out-of-school training institution in an asynchronous mode, and simultaneously outputs the earmark result to a client in a synchronous mode.

In addition, if a training institution runs, the supervision background system can apply for lap opening to the core system, the core system unfreezes the current frozen amount after passing the verification, and recovers the available balance and the like of the debit card, thereby simplifying the process of maintaining the right of the client.

And S30, responding to a transfer request of the school charge which is initiated by the training institution and carries the clearing amount, and clearing the clearing amount in the eared school charge amount through the core system, wherein the clearing amount is less than the school charge amount.

In the embodiment of the invention, the training result can periodically initiate a charge transfer request, and the core system unlocks the transfer clearing amount, namely the clearing amount is unfrozen from the frozen amount of the debit card and transferred to the account of the training institution. And carrying out multiple clearing and money transfer until the payment of the school charge is completed.

In the specific implementation process, the step S30 "clearing the money in the charged school fee amount through the core system" may adopt the following steps, and the flowchart of the method is shown in fig. 4:

s301, judging whether the clearing amount is larger than the corresponding clearing limit; if yes, go to step S302; if not, go to step S303.

S302, refusing the request of transfer of the royalty.

S303, based on the fact that a lap-opening request carrying the clearing amount is sent to the core system, the core system is enabled to open the lap in the charged fee amount and clear the amount.

In the embodiment of the invention, the clearing and transfer of the amount of the school fee are completed by multiple times of ring opening. In the specific implementation process, the training mechanism periodically sends a charge transfer request to the supervision background system in a grading way, and if the transfer request clearing amount is not within the clearing limit range, the supervision background system refuses to accept the charge transfer request so as to prevent the training mechanism from running after one-time large-amount clearing. And if the clearing amount required to be transferred is within the clearing limit range, the supervision background system accepts the charge transfer request of the training mechanism, returns the acceptance result to the training structure and asynchronously processes the charge transfer process.

The supervision background system sends a circle-off request for asking for solving the circle-off clearing amount to the core system, and after the core system receives the circle-off request, the core system unlocks the part of clearing amount from the toll amount which is already charged by the debit card. And after the core system finishes the ring-off, returning the ring-off result to the supervision background system. And if the core system fails to solve, the clearing transfer of the training fails, the core system informs the transfer failure result to the supervision background system, and then the supervision background system informs the training mechanism.

The training structure periodically requests the transfer of the charge clearing until the client finishes learning and the complete payment of the charge is finished, so that the charge is cleared by one-time earning and multiple times to realize charge supervision. After the clearing amount is unbounded from the amount of the toll that has been charged by the customer's debit card, the portion of the funds in the clearing amount is transferred from the debit card to the training structure account.

It should be noted that before the supervision background system issues a lap clearing request to the core system, in addition to verifying whether the clearing amount is greater than the clearing limit, other conditions may also be verified, for example, whether the last time that the training institution requests the transfer of the school fee clearing to the current time is greater than a time limit, taking the time limit as 3 months as an example, if the last time that the training institution requests the transfer of the school fee clearing to the current time is less than 3 months, or the current time that the training institution requests the transfer of the school fee is greater than the clearing limit, the supervision background system rejects the transfer.

And S40, transferring the cleared clearing amount from the debit card to a corresponding public account of the training institution through the core system.

In the embodiment of the invention, after the core system finishes the lap opening, the core system transfers the clearing amount of which the lap opening is finished into the account corresponding to the training institution from the debit card. At this point, the available balance of the debit card remains unchanged, the frozen amount is decremented, and the amount of the training institution account balance is incremented.

In the specific implementation process, the step S40 "transferring the unbounded clearing amount from the debit card to the account corresponding to the training institution through the core system" may include the following steps:

receiving a ring-opening result returned by the core system; and in the case that the clearing amount is determined to be successfully cleared based on the clearing result, initiating a private-to-public transaction to the core system, so that the core system transfers the clearing amount from the debit card to a public-to-public account corresponding to the training institution.

In the embodiment of the invention, the core system returns the circle-off result representing the circle-off success/failure to the supervision background system. If the lap is successfully removed, the supervision background system requests the core system to transfer the private account to the public transport, and the core system transfers the clearing amount of the lap to the public account of the training institution from the debit card.

The core system returns the transaction result to the supervision background system, and the supervision background system outputs the transaction result to the training institution. In addition, when the loading or unloading of the core system or the transaction is not clear and the loading result/unloading result/transaction result is not timely received by the training result, the supervision background system also provides transaction result query so that the training institution can timely acquire the related result.

The invention adopts a synchronous acceptance mechanism and an asynchronous processing mechanism to quickly respond that a client pays a school fee to a training institution, adopts a freezing mechanism to pay the school fee to an out-of-school training institution on the premise of ensuring the fund safety of the client, and adopts a fee deduction mechanism to periodically collect the school fee by the training institution on the premise of limiting the large-amount fee collection of the out-of-school training institution, thereby realizing virtuous cycle operation and further realizing the final target of the school fee supervision.

The invention has the advantages that the debit card is used for one-time credit-sharing and multiple-time lap-opening, when a customer uses the debit card for payment, the school fee is frozen in the account of the customer, and the school fee is collected by the extraschool training institution in a limited amount, and is cleared for multiple times, so that the purpose of school fee supervision is achieved. Therefore, the problem of preventing the training mechanism from running is solved, and the benefit of the student can be maintained.
