Abstract

A payment system, method, and device based on a shared funds management server, in the field of e-commerce. A funds-management server receives payment request information sent by a client end, compares the sum of the credit overdraft limit, credit loan limit, and funds balance of the client end with a payment amount to determine whether an electronic commitment payment certificate can be created. If yes, the server freezes the credit overdraft limit, credit loan limit, and funds balance in an amount corresponding to the payment amount, then generates an electronic commitment payment certificate for the server to commit to pay funds according to an agreed condition, and sends the certificate to a merchant end to make a credit commitment payment on behalf of the client end, and synchronizes to an information centre server.
Supervising both parties in a transaction reduces financial risk and ensures the interests of both parties.

[34] The client 10, connected with the Funds-Management server 30, is configured to transmit the payment request information to the Funds-Management server 30, wherein the payment request information includes the payment amount.

[35] 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 information of the client 10 is filled in when the customer registers and stored in the database of the Funds-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 information such as the written and confirmed price (payment amount), the receipt address and the like after the customer purchases the specific goods / services. According to the pre-set rules, Date Recue/Date Received 2020-06-10 price of the goods/services, and commercial tenants of the goods/services, the merchant generates data package; the packet will be transmitted to the Funds-Management server 30. The payment request information includes at least the payment amount, and may include the merchant information and the merchandise information. Among them, the merchant information can be directly merchants' receiving account number, you can also uniquely identify the merchant information (such as merchant ID), and find the corresponding bank account information by Fund-Management server 30 based on the unique identification of the merchant from the database. 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 Funds-Management server 30 inquires the merchant's receiving account by using the correspondence relationship between the merchant ID and its receiving account.
In other words, the client 10 only needs to inform the Fund-Management server 30 which merchant's which goods need to be paid how much money, then the Fund-Management server 30 will be able to call out the merchant account to implement the appropriate payment operation.

[36] The merchant 20 is connected to the Funds-Management server 30 for receiving the electronic commitment payment certificate sent by the Funds-Management server 30.

[37] 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 Fund-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 transmitted from the second Funds-Management server 30, and extracts the merchandise information and the goods receipt information in the electronic commitment payment voucher information to designate the merchandise transmission destination.

[38] The funds management server 30 is used for receiving payment request information delivered by a client 10; comparing the sum of credit overdraft limit, credit loan limit Date Recue/Date Received 2020-06-10 and a funds balance in the client 10 with a payment amount to determine whether an electronic commitment payment certificate can be created; if possible, freezing the payment amount corresponding to the credit overdraft limit and credit loan limit within a client account; generating the electronic commitment payment certificate by the Funds-Management server to commit to pay funds according to an agreed condition, and delivering the electronic commitment payment certificate to a merchant 20 and synchronize to the information centre server 40.

The second Funds-Management server 30 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.

[40] It is understandable that the frozen payment amount corresponding to the credit overdraft limit, credit loan limit and funds balance included the following cases:

[41] 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.

[42] 2. Only freezing the credit loan limit so that the total frozen amount of the greater than or equal to the payment amount.

[43] 3. Only freezing the amount of credit overdraft limit so that the total frozen amount are greater than or equal to the amount of the payment.

[44] 4. Freezing the part of the balance of funds and credit loan limit in the client's account respectively, making the total frozen amount is greater than or equal to the payment amount.

[45] 5. Freezing the part of the balance of funds and credit overdraft limit in the client's account respectively, making the total frozen amount is greater than or equal to the Date Recue/Date Received 2020-06-10 payment amount.

[46] 6. Freezing the part of the credit loan limit and credit loan limit respectively, making the total frozen amount is greater than or equal to the payment amount.

[47] 7. Freezing the part of the credit overdraft limit and credit loan limit in the client's account respectively, making the total frozen amount is greater than or equal to the payment amount.

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

[49] Specifically, both the client 10 and the merchant 20 can obtain the electronic commitment payment certificate information to the information centre server 40 via the Internet for subsequent processing, such as the correctness of the dual channel authentication information using the data. The Funds-Management server 30 may further determine whether or not the payment operation is made in accordance with the state of the electronic commitment payment certificate information, that is, the payment request only freezes the balance of the credit overdraft limit, credit loan limit and funds balance, transferring and deducting the credit limit after confirming receipt.

[50] In the present example, the same Funds-Management server 30 may be connected to the plurality of client 10 and the plurality of merchant 20 through the Internet at the same time. That is, the server where the client 20 account is located and the server where the client 10 resides are the same Fund-Management server 30. The Fund-Management server 30 can be a single or multiple servers in a physical sense, e.g., they can work in parallel, and the resources of the server are automatically allocated to realize the Fund-Management according to the different traffic.

[51] Example 2

[52] As shown in Figure 2, an example of the present invention provides a payment method based on the same Funds-Management server for use in the Funds-Management server, which method comprises the steps of:

[53] S201, the Funds-Management server receives the payment request information sent by the client, wherein the payment request information includes at least the payment amount;

[54] Specifically, the payment request information received by the Funds-Management server includes merchant information, product information and payment amount, and may include merchant information (e.g., client ID). Among them, the merchant information can be directly merchants receiving account number, you can also uniquely identify the merchant information (such as merchant ID), and find the corresponding bank account information by Fund-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 Fund-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 Fund-Management server to which merchant and which goods to pay the amount of funds, the Fund-Management server will be able to call out the account of the implementation of the corresponding payment operation.

[55] S202, comparing the sum of credit overdraft limit, credit loan limit and funds balance to determine whether an electronic commitment payment certificate can be generated to make a credit commitment payment, if so, then enter into the payment process, otherwise terminate the payment. It is understandable that the credit overdraft limit is usually deposited in a credit card, usually the credit loan limit matches credit reporting in this example.

[56] This step further includes: the Funds-Management server check the credit overdraft limit, credit loan limit and funds balance in the client from the database;
determine whether the sum of credit overdraft limit, credit loan limit and funds balance is greater than or equal to the amount of payment, if so, then allow the payment;
otherwise Date Recue/Date Received 2020-06-10 terminate the payment. Wherein the client's bank account and credit card account can be notified to the Funds-Management server by the client in the payment request, or can be queried from the database according to the client ID so that the credit overdraft limit, credit loan limit and funds balance of the account is obtained by the fund management server. Only the credit overdraft limit, credit loan limit and funds balance in the client account is greater than or equal to the payment amount, it means that customers have the ability to pay, then the payment is allowed. As a result, it can save the payment cycle and protect the interests of seller.

[57] S203, the Funds-Management server respectively freezing the payment amount corresponding to credit overdraft limit, credit loan limit and funds balance in the client account, making the total frozen amount is greater than or equal to the amount of the payment.

[58] This step only freezes the credit overdraft limit, credit loan limit and funds balance to ensure that the sum of the total account is greater than or equal to the amount of the payment amount; make sure there is sufficient funds to complete the transaction, but not directly transfers to the merchant account, and it ensures the interests of the buyers and the sellers, later, the client, the merchant or logistics company deliver the payment information to confirm the delivery is complete. After the Funds-Management server receives the payment information, deduct the credit loan limit or credit overdraft limit and release the related funds and transfer the funds to the merchant's account.

[59] S204, the Funds-Management server generates an electronic commitment payment the certificate;

[60] Specifically, since the payment request information is sent by the buyer to the Funds-Management server through the merchant operation, the payment information is objectively confirmed by the customer and authorized by the bank. Funds-Management server respectively freezes the corresponding credit overdraft limit, credit loan limit and funds balance, and generates an electronic commitment payment certificate based on the payment information. The electronic commitment payment certificate information includes but not limited to product information, payment amount (frozen funds or credit loan limit or credit loan limit), delivery address and validity period, the form is not limited to text, pictures, graphics and so on. The electronic certificate is the certificate of Date Recue/Date Received 2020-06-10 the receiving end of the merchant, and the merchant provides the corresponding goods /
service according to the electronic commitment payment certificate.

[61] S105, deliver the electronic commitment payment certificate to the client for the client and synchronized it to the information centre server.

[62] Specifically, this step sends the generated electronic certificate information to the information centre server so that the information centre server performs subsequent tracking.

[63] The payment method based on the frozen credit overdraft limit, credit loan limit and funds balance provided by the example in the present invention receives the payment request information of the client through the Funds-Management server, based on the sum of credit overdraft limit, credit loan limit and funds balance of the buyer to determine whether to pay or not, and by freezing the credit overdraft limit, credit loan limit and funds balance in the client account, and generating electronic commitment payment certificate and synchronize to the information centre for conducting real-time monitoring, which can reduce the risk of funds to protect the interests of the buyers and the sellers.

[64] Example 3

[65] As shown in Figure 3, the payment method of credit overdraft limit, credit loan limit and funds balance provided of the example in this invention were applied in the payment system of same Funds-Management servers as shown in Figure 1, which including the following steps:

[66] S301, the client sends the payment request information to the Funds-Management server, the payment request information includes the payment amount, and the Funds-Management server receives the payment request information sent by the client.

[67] 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 Date Recue/Date Received 2020-06-10 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.

[68] The way the client sends payment request information to the 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 his 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 to use the symmetric password to decrypt the information obtained. This ensures the authenticity and integrity of the data transmission.

[69] S203, inquiring the sum of the credit overdraft limit, credit loan limit and funds balance, and comparing the sum of the credit overdraft limit, credit loan limit and funds balance with the payment amount, if the sum is greater than or equal to the amount, it indicates sufficient; if the sum is less than the amount, it indicates insufficient.
