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.

[34] Example 1

[35] As shown in Figure 1, an example of the present invention provides a payment system based on the same Fund-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,

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

[37] 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 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 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, 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 Fund-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 Fund-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.

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

[39] Specifically, the merchant 20 is applied to the receiving party (seller), and the merchant end 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 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.

[40] The Fund-Management server 30 receives the payment request information sent from the client 10, determines whether or not the payment is allowed based on the credit overdraft limit, the fund balance, the credit loan limit and the payment amount of the client 10; if the payment is allowed, the credit limit or funds corresponding to the client account and payment amount shall be freeze, an electronic commitment payment certificate which is promised to pay the funds by the Fund-Management server in accordance with the agreed condition will be generated, the electronic commitment payment certificate information shall be sent to the merchant end 20.

[95] Wherein the payment request information is composed of a plurality of data packets, including at least the merchant information, the merchandise 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 Fund-Management server based on the unique identification of the merchant from the database. In the specific application, the account information of the merchant end 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.

[96] The way the client sends payment request information to the Fund-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.

[111] S201, the client sends the payment request information to the Fund-Management server, the payment request information includes the payment amount, and the Fund-Management server receives the payment request information sent by the client.

[112] Wherein the payment request information is composed of a plurality of data packets, including at least the merchant information, the merchandise 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 Fund-Management server based on the unique identification of the merchant from the database. In the specific application, the account information of the merchant end 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.

[113] The way the client sends payment request information to the Fund-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.
