[0030] The client 10 is connected with server 40 of the second Funds-Management server for transmitting the payment request information to the second Funds-Management server 40, and the payment request information includes the payment amount.

[0031] Specifically, the client 10 is suitable for the payer (buyer), including the account information of mobile phone, personal computer, PAD, and other intelligent devices, the account Date Recue/Date Received 2020-09-24 information of the client 10 is filled in when the customer registers and stored in the database of the Fund-Management service and (or) the information centre server, the account information of the client 10 includes customer ID, an account opening bank, account name, a bank account number, and a credit balance, and may also include the customer's shipping address. The payment request information is the information that the customer has written and confirmed shipping address information after the customer purchases the specific goods/services. According to the pre-set rules, price of the goods/services, and commercial Merchants of the goods/services, the client 10 generates data package; the packet will be transmitted to the second Funds-Management server 40. The payment request information includes at least the payment amount, and may include the Merchant information and the product information. Among them, the Merchant information can be directly the Merchant's receiving account, it can also uniquely identify the Merchant information (for an example, Merchant ID), by the Funds-Management server 40 on the unique identification of the merchant from the database to find the corresponding bank account information. In the specific application, the account information of the Merchant 20 should be kept confidential with respect to the client 10, so the Merchant information is preferably the Merchant ID, and the second Funds-Management server 40 inquires the Merchant's receiving account by using the corresponding relationship between the Merchant ID and its receiving account number. In other words, the client 10 only needs to inform the second Funds-Management server 40 to which Merchant and which goods to pay the amount of funds, the second Funds-Management server 40 will be able to call out the Merchant account to implement the appropriate payment operation.

[0032] The Merchant 20 is connected to the first Funds-Management server 30 for receiving the electronic commitment payment certificate transmitted by the second Funds-Management server 40.

[0033] Specifically, the Merchant 20 is adapted to the recipient (Merchant), and the Merchant includes but not limited to devices such as servers, and POS machines and so on.
Merchants include but not limited to manufacturers, agents, logistics companies, etc. The merchant information is also registered in the database of the Funds-Management server and (or) the information centre server, and the merchant information includes, but not limited to merchant ID, merchant name, merchant opening bank, merchant account name, and merchant bank account number. The Merchant 20 receives the electronic commitment payment voucher Date Recue/Date Received 2020-09-24 transmitted from the second Funds-Management server 40, and extracts the merchandise information and the goods receipt information in the electronic commitment payment voucher information to designate the merchandise transmission destination.

[0035] Specifically, the second Funds-Management server 40 receives the packet of the payment request information and analyses it according to the reset rule to obtain the relevant payment information including but not limited to the Merchant information, the merchandise information, and the payment amount And other necessary information, that is, to which Merchant which goods to pay the amount of money. The second Funds-Management server 40 inquires whether the balance of the bank funds and the credit overdraft amount of the client account is sufficient for the current settlement, and if it is insufficient, the payment is terminated and, if sufficient, the balance of the payment amount and the amount of credit overdraft, So that the total amount of the freeze is greater than or equal to the amount of the payment, until the merchant confirms the delivery or the customer confirms the receipt after the transfer operation.

[0036] It is understandable that the amount of funds to be frozen and the corresponding amount of credit overdrafts are included in the following cases:
1. Only the balance of the funds in the client account is frozen so that the total amount of the freeze is greater than or equal to the amount paid.
2. Only the credit loan limit is frozen so that the total amount of the greater than or equal to the payment amount.
3. Respectively, part of the client account to freeze the balance of funds and credit overdraft limit, so that the total amount of frozen greater than or equal to the amount of the Date Recue/Date Received 2020-09-24 payment.

[0037] The information centre server 50 is connected to the second Funds-Management server 40 and the first Funds-management server 30 for storing the electronic commitment payment certificate information of the client 10 and the merchant 20.

[0038] Specifically, both the client 10 and the merchant 20 can obtain the electronic commitment payment certificate information to the information centre server 50 via the Internet for subsequent processing, such as the correctness of the dual channel authentication information using the data. Specifically, the second Funds-Management server 40 may further determine whether or not the payment operation is made in accordance with the state of the electronic commitment to pay the certificate information, that is, the payment of the balance of the funds and the amount of the credit overdraft, credit limit.

[0039] In the present example, the second Funds-Management server 40 may be connected to the plurality of clients 10 and via the Internet at the same time. The first Funds-Management server 30 may be connected to a plurality of Merchant terminals 20 and via the Internet at the same time. That is, the server where the Merchant 20 is located is not on the same server as the server where the client 10 is located. The second Funds-Management server 40 and the first Funds-management server 30 can be a single server in the physical sense, or it can work in parallel for multiple servers in the physical sense, such as multiple physical servers. According to the different traffic, the resources of the server are automatically allocated to realize the Fund-Management. The second Funds-Management server 40 and the first Funds-Management server 30 includes but is not limited to servers in institutions such as banks, businesses, and so on. In the practical applications, it can be understood as the same bank's cluster Funds-Management server, but not limited to banks, but also the Internet to support the flow of funds in other institutions. Through the Funds-Management server and information centre server, the seller and seller of information are regulated, and the regulatory functions are merged into the bank or other institutions with credit ability to pay.

Among them, the merchant information can be merchants' account number, and it can also be the only identification of the merchant information (such as merchant ID), to find the corresponding bank account information based on the unique identification of the business from the database by the second Funds-Management server. In the specific application, the account information of the Merchant should be kept confidential with respect to the client .so the Merchant information is preferably the Merchant ID, and the second Funds-Management server inquires the Merchant's receiving account by using the corresponding relationship between the Merchant ID and its receiving account number. In other words, the client only needs to inform the second Funds-Management server to which Merchant and which goods to pay the amount of funds, the second Funds-Management server will be able to call out the Merchant account to implement the appropriate payment operation.

[0044] S202, the second Funds-Management server receives the client to send the payment request information;

[0045] S203, inquiring the sum of the funds balance of the client account and the amount of the credit overdraft, comparing the sum of the funds balance and the amount of the credit overdraft with the payment amount, if the sum is greater than or equal to the amount, it is sufficient; if the sum is less than the amount, it is insufficient. When the funds balance and credit overdraft limit is sufficient, executing the Step S204, otherwise terminating, not to pay;

[0046] S204, the second Funds-Management server to freeze the client account within the amount of payment corresponding to the balance of funds and credit overdraft capacity;
understand that the amount of the corresponding payment of the corresponding amount of funds balance and credit overdraft capacity, including the following circumstances :
1. Only the balance of the funds in the client account is frozen so that the total amount of the frozen is greater than or equal to the payment amount.
2. Only the credit loan limit is frozen so that the total amount of the greater than or equal to the payment amount.
3. Respectively, some of the client's account to freeze the balance of funds and credit Date Recue/Date Received 2020-09-24 overdraft limit, making the total amount of frozen greater than or equal to the amount of the payment.

[0047] S205, the second Funds-Management server generates the electronic commitment payment certificate based on the payment request information and the freezing information and transmits the electronic commitment payment certificate to the Merchant;

[0048] Specifically, since the payment request information is sent by the buyer to the second Funds-Management server through the client's operation, the payment information is objectively confirmed by the customer and authorized by the bank. The second Funds-Management server freezes the corresponding funds and generates an electronic commitment payment certificate based on the payment information, and the Merchant provides the corresponding merchandise/service according to the electronic commitment payment certificate.

[0049] S206, the second Funds-Management server sends the electronic payment certificate to the second terminal and synchronizes to the information centre server and the first Funds-Management server; Specifically, this Step sends the generated electronic certificate information to the information centre server so that the information centre server performs subsequent tracking.

[0050] S207, the second Funds-Management server receives the payment information;

[0051] S208, the second Funds-Management server allocates the funds corresponding to the freezing amount to the first Funds-Management server;

[0052] S209, the first Funds-Management server transfers the received payment amount to the account of the Merchant.

[0053] The payment method provided by the example of the present invention receives the payment request information of the client through the second Funds-Management server, determines whether the payment is permitted based on the sum of the funds balance and the payment amount of the client account, and by freezing the funds balance and the credit overdraft limit of the client account to generate electronic commitment payment certificate to supervise in real-time, which can reduce the risk of funds and protect the interests of the buyers and the sellers.

[0054] Example 3

[0055] As shown in Figure 3, a preferred example of the present invention provides a payment method for funds balance and credit overdraft limit which applied to the cross Funds-Date Recue/Date Received 2020-09-24 Management server payment system shown in Figure 1, comprising the following steps:

[0056] S301, the client sends the payment request information to the second Funds-Management server, and the payment request information includes at least the payment amount.

[0057] And the payment request information is composed of a plurality of data packets, including at least the Merchant information, the product information and the payment amount.
You can also include client information (such as client ID). Among them, the merchant information can be directly merchants receiving account number, you can also uniquely identify the merchant information (such as business ID), and find the corresponding bank account information by Funds-Management server based on the unique identification of the merchant from the database. In the specific application, the account information of the merchant should be kept confidential with respect to the client, so the merchant information is preferably the merchant ID, and the Funds-Management server inquires the merchant's receiving account by using the correspondence relationship between the merchant ID and its receiving account. In other words, the client only need to inform the Funds-Management server to which merchant and which goods to pay the amount of funds, the Funds-Management server will be able to call out the account of the implementation of the corresponding payment operation.

[0058] The way the client sends payment request information to the second Funds-Management server can be done in the existing way, such as using a digital signature or a digital envelope. A digital signature is a data that the user encrypts a hash of the original data with own private key. The information recipient obtains the hash digest by decrypting the digital signature attached to the original information using the public key of the sender of the information and confirms whether the original information is made by comparing with the hash digest generated by the original data received by the information recipient tampered with. This ensures that the data transmission is undeniable. Digital envelopes use password technology to ensure that only the recipient of the specified information can read the contents of the information. Digital envelopes used in a single-key password system and public key password system.
The information sender first encrypts the information with the randomly generated symmetric password, and then encrypts the symmetric password with the public key of the receiver. The symmetric password encrypted by the public key is called the digital envelope.
In the transmission of information, the information receiver shall decrypt the information, you must first use their own private key to decrypt the digital envelope, get a symmetric password, in order Date Recue/Date Received 2020-09-24 to use the symmetric password to decrypt the information obtained. This ensures the authenticity and integrity of the data transmission.

[0059] S302, the Funds-Management server receives the payment request information sent by the client.

[0060] Specifically, the payment request information received by the second Funds-Management server includes Merchant information, product information and payment amount, and it may also include the client information (for an example, client ID).
Among them, the merchant information can be merchants' account number, and it can also be the only identification of the merchant information (such as merchant ID), to find the corresponding bank account information based on the unique identification of the business from the database by the second Funds-Management server. In the specific application, the account information of the Merchant should be kept confidential with respect to the client .so the Merchant information is preferably the Merchant ID, and the second Funds-Management server inquires the Merchant's receiving account by using the corresponding relationship between the Merchant ID and its receiving account number. In other words, the client only needs to inform the second Funds-Management server to which Merchant and which goods to pay the amount of funds, the second Funds-Management server will be able to call out the Merchant account to implement the appropriate payment operation.

[0061] S303, inquiring the sum of the funds balance of the client account and the amount of the credit overdraft, comparing the sum of the funds balance and the amount of the credit overdraft with the payment amount, if the sum is greater than or equal to the amount, it is sufficient; if the sum is less than the amount, it is insufficient. When the balance of funds and credit overdraft is sufficient, executing Step S305, or executing steps;

[0062] S304 asks the client whether to issue credit loan limit; if it is needed, executing Step S305, or terminating the process;

[0063] S305, judging whether the credit loan limit is sufficient; the sufficient can be understood in several cases:
1. If the sum of the original funds balance of the client account and the amount of the credit overdraft limit as well as the credit loan limit are greater than or equal to the amount of the payment amount, the credit loan limit is considered to be sufficient; and conversely, it is insufficient;

Date Recue/Date Received 2020-09-24 2. When the credit loan limit is greater than or equal to the amount of the payment amount, the credit loan limit is considered to be sufficient and, conversely, insufficient.

[0064] Specifically, the credit loan limit can be the amount specified by the client, or it can default to the amount of the current payment. For example, when the price of a product selected by the customer is 1,500 Yuan (payment amount), if the customer account funds balance and credit overdraft limit only 900 Yuan, you need credit loan limit of 600 Yuan in order to meet the allowable payment to pay the act. Of course, the using of another way, such as the direct application for credit loan limit of 1,500 Yuan, to pay, is also feasible.

[0065] S306, the second Funds-Management server to freeze the client account within the balance of funds and credit overdraft limit and credit loan limit, so that the total amount of frozen are greater than or equal to the amount of the payment, it can be specifically divided into the following forms:
1. Only the balance of the funds in the client account is frozen so that the total amount of the frozen is greater than or equal to the payment amount.
2. Only the credit loan limit is frozen so that the total amount of the greater than or equal to the payment amount.
3. Only to freeze the amount of credit overdraft limit, so that the total amount of frozen are greater than or equal to the amount of the payment.
4. Respectively, some of the client's account to freeze the balance of funds and credit overdraft limit, making the total amount of frozen greater than or equal to the amount of the payment.
5. Respectively, some of the client's account to freeze the balance of funds and credit loan limit, making the total amount of frozen greater than or equal to the amount of the payment.
6. Respectively, some of the client's account to freeze the credit loan limit and credit overdraft limit, making the total amount of frozen greater than or equal to the amount of the payment.
7. Respectively, some of the client's account to freeze the credit loan limit and credit overdraft limit, as well as the funds balance, making the total amount of frozen greater than or equal to the amount of the payment.

[0066] S307, the second Funds-Management server generates the electronic commitment payment certificate according to the payment request information and the freezing information;

Date Recue/Date Received 2020-09-24

[0067] Specifically, since the payment request information is sent by the buyer to the second Funds-Management server through the client's operation, the payment information is objectively confirmed by the customer and authorized by the bank. The second Funds-Management server will freeze the corresponding the funds balance, credit overdraft limit or credit loan limit;
meanwhile, it will generate an electronic commitment payment certificate based on the payment information, and the Merchant will provide the corresponding goods/services according to the electronic commitment payment certificate.

[0068] S308, the second Funds-Management server sends the electronic payment certificate to the second terminal and synchronizes to the information centre server and the first Funds-Management server; Specifically, this Step sends the generated electronic certificate information to the information centre server so that the information centre server performs subsequent tracking.

[0069] S309, the second Funds-Management server receives the payment information; it should be noted that In Step S408, the Merchant sends and receives the payment information to the Funds-Management server only as an example, and in practice, the client, a logistics server, or other entity that is aware of the delivery status to send payment information to the Funds-Management server.

[0070] S310, the second Funds-Management server allocates the funds corresponding to the freezing amount to the first Funds-Management server; it is understood that there will be a corresponding matching fund allocation scheme according to the different freezing methods in Step S306, and the funds allocated to the account of the Merchant.

[0071] S311, the first Funds-Management server transfers the received payment amount to the account of the Merchant

[0072] Finally, the process is ended.

[0073] The example of the present invention, on the basis of the second example, not only facilitates the buyer, but also greatly enriches the business of the bank or other institution with the credit payment ability by increasing the credit loan limit function;
