[30] [Description of the Preferred Examples]

[31] The present invention will be described in further detail with reference to the accompanying drawings and the accompanying example, in which the technical problems, technical solutions and advantages to be solved by the present invention will become more apparent. It is to be understood that the specific examples described herein are merely illustrative of the invention and are not intended to limit the invention.

[32] Example 1

[33] As shown in Figure 1, an example of the present invention provides a payment system based on the same Funds-Management server, which includes at least one client 10, at least one merchant 20, and a Funds-Management server 30; the Funds-Management server 30 is connected to the client 10, and the merchant 20 respectively,

[34] The client 10, connected with the fund 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), such as the intelligent devices used by a client, including a mobile phone, a personal computer, and a PAD, the account information of the client 10 is to fill in when the customer registers and store to the database of the Funds-Management server, the account information of the client 10 includes information such as a customer ID, an account opening bank, an account name, a bank account number, and a credit balance and so on, and it may also include the customer's shipping address information. The payment request information is information such as the written and confirrned price (payment amount), the receipt address and the like 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 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 Funds-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 Funds-Management server 30 which merchant's which goods need to be paid how much money, then the Funds-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 applied to the receiving party (seller), and the merchant includes but not limited to devices such as servers, POS machines and other devices.
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 the Merchant information includes, but not limited to, Merchant ID, Merchant name, Merchant bank, Merchant account name, and bank Merchant 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 receiving payment request information sent by a client 10; comparing the sum of a funds balance and a credit overdraft limit of the client with a payment amount to determine whether an electronic commitment payment certificate can be created; if possible, the Funds-Management server respectively freezing the funds balance and the credit overdraft limit within a client and account, the funds balance and the credit overdraft limit corresponding to the payment amount; generating the electronic commitment payment certificate for the Funds-Management server to commit to pay funds according to an agreed condition, and sending the electronic commitment payment certificate to a Merchant 20 to make a credit commitment payment on behalf of the client.

[39] Specifically, the Funds-Management server 30 receives the packet of the payment request information and parses it according to the pre-set rule to obtain the relevant payment information including, but not limited to, the merchant information, the merchandise information, and the payment amount, and the like information, which merchant to which the goods to pay the amount of money. 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 amount of funds to be frozen and the corresponding amount of credit overdrafts are included in 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 the credit loan limit is frozen so that the total amount of the greater than or equal to the payment amount.

[43] 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 payment.

[44] Specifically, the second Funds-Management server 30 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.

[45] 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 Funds-Management server 30. The Funds-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. The Funds-Management server includes but not limited to servers in organizations 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. To supervise the the information of the buyers and sellers by the Funds-Management server which can regulate the regulatory function into the bank or other institutions with credit ability to pay.

[46] Example 2

[47] 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:

[48] 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;

[49] Specifically, the payment request information received by the Funds-Management server includes merchant information, product information and payment amount, and may include client information (e.g., customer 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 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.

[50] S202, the client's balance of funds and credit lines and the sum of the amount of payment to determine whether to generate electronic commitment to pay the certificate to be paid, if allowed, then enter the payment process, or terminate the payment. It is to be understood that in this embodiment, the balance of funds is usually stored in a debit card, which typically matches the credit.

[51] This Step further includes: the Funds-Management server from the database query client account balance; determine whether the balance of funds is greater than or equal to the amount of payment, if so, then allow the payment; otherwise terminate the payment.
Wherein the bank account of the client can be informed to the Funds-Management server by the client in the payment request, or can be queried from the database according to the client ID by the Funds-Management server. Only in the client account of the funds balance or credit limit greater than or equal to the payment amount, it means that customers have the ability to pay behaviour, this time to allow payment behaviour. So, you can save the payment cycle, protect the interests of businesses.

[52] S203, 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.

[53] This Step only to freeze the payment amount or credit limit to ensure that there is sufficient funds to complete the transaction, but not directly transfer to the merchant account, so to ensure the interests of the buyers and the sellers, followed by the client, the merchant or logistics company to send the payment information to confirm the delivery is completed by the Funds-Management server to receive the payment of information, the re-blocked funds will be allocated to the merchant account.

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

[55] Specifically, since the payment request information is sent by the buyer to the Funds-Management server through the client operation, the payment information is objectively confirmed by the customer and authorized by the bank. The second Funds-Management server 40 respectively freezes the corresponding balance of funds and the amount of credit overdraft limit, and generates an electronic commitment payment certificate based on the payment information. The electronic commitment payment certificate information includes but is not limited to commodity information, payment amount (frozen funds or credit overdraft 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 the receiving end of the merchant, and the merchant provides the corresponding goods / service according to the electronic commitment payment certificate.

[56] S205, the electronic commitment payment certificate issued to the client for the client to undertake credit commitments. For subsequent tracking.

[57] The payment method illustrated by the example of the present invention can reduce the risk of funds and protect the interests of the buyers and the sellers through the Funds-Management server receiving the payment request information of the client, determining whether or not the payment is permitted based on the credit overdraft limit, funds amount, or credit loan limit in the client account, then at the same time freezing the payment account in the client, and generating electronic commitment payment certificate.

[58] Example 3

[59] As shown in Figure 3, an example of the present invention provides a payment method of the funds credit loan limit, applied in the same Funds-Management servers as shown in Figure 1, which is comprised of the steps as follows:

[60] 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.

[61] 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 merchant 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.

[62] 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.

[63] S302, 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;

[64] S303, 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:

[65] 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.

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

[67] 3. 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.

[68] S304, the Funds-Management server generates an electronic commitment payment the certificate;

[69] S305, sending the electronic commitment payment certificate information to the merchant

[70] S306, the merchant sends the receiving and receiving information to the Funds-Management server;

[71] It is to be noted that in Step S210, the merchant sends and receives the payment information to the Funds-Management server as an example. In practice, it is also possible for the client, the logistics server, or other entity that can know the delivery status to send the payment information to the Funds-Management server.

[72] S307, the money management server synchronizes the payment information to the merchant or the client.

[73] Specifically, the Funds-Management server synchronizes the updated electronic commitment payment certificate information to the information centre server, from the updated electronic commitment payment certificate information to immediately inform the merchandise of the circulation state, when the goods / service delivery is completed, Of the funds to the merchant account.

[74] S308, the funds corresponding to the freezing amount are allocated to the account number of the merchant. It can be understood that, according to the different method of freezing in S303, there will be a matching allocation plan, which will allocate the corresponding funds to the account of the merchant.

[75] S309, end the process.

[76] The payment method and server provided by the example of the present invention receives the payment request information of the client, determines whether the payment is permitted based on the sum of the funds balance and the credit overdraft limit 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.

[77] Example 4

[78] As shown in Figure 4, an example of the present invention provides a payment method of the credit overdraft limit, and applied in the payment system of the same Funds-Management server in Figure 1, which method comprises the steps of:

[79] S401, the Funds-Management server receives the payment request information sent by the client.

[80] 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 merchant 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.

[81] 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.

[82] S402, 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;

[83] S403, 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:

[84] 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.

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

[86] 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.

[87] 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.

[88] 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.

[89] 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.

[90] 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.

[91] S404, asks the client whether to issue credit loan limit; if it is needed, executing Step S305, or terminating the process;

[92] S405, judging whether the credit loan limit is sufficient; the sufficient can be understood in several cases:

[93] 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;

[94] 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.

[95] 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.

[96] S406, 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:

[97] S407, sending the electronic commitment payment certificate information to the merchant

[98] S408, the merchant sends the receiving and receiving information to the Funds-Management server;

[99] It is to be noted that in Step S408, the merchant sends and receives the payment information to the Funds-Management server as an example. In practice, it is also possible for the client, the logistics server, or other entity that can know the delivery status to send the payment information to the Funds-Management server.

[100] S409, the money management server synchronizes the payment information to the merchant or the client.

[101] Specifically, the Funds-Management server synchronizes the updated electronic commitment payment certificate information to the information centre server, from the updated electronic commitment payment certificate information to immediately inform the merchandise of the circulation state, when the goods / service delivery is completed, Of the funds to the merchant account.

[102] S410, the funds corresponding to the freezing amount are allocated to the account number of the merchant. It can be understood that, according to the different ways of freezing in S403, there will be a matching allocation plan, which will allocate the corresponding funds to the account of the merchant.

[103] S411, end the process.

[104] The example of the present invention, on the basis of the example 3, 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; Keeping Buyers and sellers' electronic commitment certificate to track synchronization, the flow of goods and the flow of funds trajectory can be effective combined to protect the interests of both buyers and sellers effectively.

[105] Example 5

[106] As shown in Figure 5, an example of the present invention provides a payment device including a receiving module 301, a judgement module 302, and a processing module 303, wherein:

[107] The receiving module 301 is configured to receive payment request information transmitted by the client, and the payment request information includes the payment amount.

[108] Specifically, the payment request information received by the receiving module 301 includes Merchant information, product information and payment amount, and may include the client information (for an example, customer ID). Among them, the merchant information can be merchants receiving account, and the merchant information can also be uniquely identified (such as merchant ID). In the particular application, the account information of the merchant should be kept confidential from the client, so the merchant information should be the merchant ID, that is, the client simply informs which merchandise of which merchant is paid by how much, then the device call out of the merchant account number to implement the corresponding payment operation.
