Of course, the functions completed by the payment platform 〇 3 can also be integrated into the intermediate platform 2. The payment platform 3 takes Alipay as an example. User 4 can open an account on Alipay and store a certain amount of money directly on the account or store it. The user 4 only needs to purchase the goods of the merchant 1 and only needs to pay through the Alipay. You can do the deduction. And through the above methods, the merchants only need to complete the reconciliation work with Alipay on a regular basis. At least one server center 1 1 and a database 12 are disposed on the intermediate platform 2. The server center 11 is used to process each transaction request. The database 12 is used to record each transaction in real time. -5- 201040863 Through the above-mentioned network father, it is easy for merchants 1 and 4 to conduct transactions through the intermediate platform 2, which greatly improves the security of transactions. For the user, since the merchant 1 belongs to a virtual merchant on the Internet, it is impossible to determine the authenticity of the fact that it is impossible to determine the quality problem for the purchased object, and the payment is made through the intermediate platform 2, which saves such concerns. For the merchant 1, the trust with the user 4 is established through the intermediate platform 2, which can reduce the distrust of the user and increase the sales volume. This trading model has achieved a rapid development of the business, customer 4 and intermediate platform 2 win-win model. Moreover, in the above-mentioned online shopping field, it is still continuing to sell goods by means of merchants or through direct delivery and collection by a logistics company. This trading mode has the following shortcomings: First: the existing trading methods have the phenomenon that the user has no sense of trust in the merchants and does not purchase the goods, and the success rate of the transactions is reduced, especially the payment means provided by the payment platform is not satisfied. The demand can not meet the demand for online shopping payment for users who are not worried about purchasing online commodities. Secondly, the existing transaction method also has the inconsistency between the pictures or images that the network sees when the user purchases the product and the actual purchase. The phenomenon of disputes; Third: If the existing trading method entrusts the logistics company to collect the money, the logistics company will pay very slowly, which will cause financial pressure on the merchants. Fourth: In the existing trading methods, if the logistics company is entrusted to collect money, each merchant entrusts different logistics companies, and there is no uniform standard for the logistics company, which is prone to various trading situations. In particular, when a logistics company defaults on payment, the transaction has its own safety issues. -6 - 201040863 SUMMARY OF THE INVENTION An object of the present invention is to provide a network transaction method with greater scalability and security.

The intermediate platform and the payment platform are connected through a dedicated line or through a regional network or through the Internet. In the present invention, the intermediate platform 22 is mainly to establish a platform for merchants to conduct transactions with users. The intermediate platform 22 at least stores the subscription information of each merchant's registration information of the user and the contract information of each logistics company. The intermediate platform 22 is used to process and save transactions for each transaction. The payment platform 23 is mainly used to complete the financial clearing and settlement work with merchants and logistics companies. -13- 201040863 The logical classification of the intermediate platform 2 2 and the payment platform 23 is specifically described below. The intermediate platform 22 includes at least a first server 221 and a first database 222. The intermediate platform 22 also includes network peripherals connected to the Internet and network security devices (such as firewalls) for improving their security, since the devices are common and commonly used for a network transaction platform. I won't go into details here. The first server 221 further includes: a user processing sub-unit 223 for receiving and processing various requests made by the user including the registration of the user, the transaction request of the user, and establishing and saving the interaction with the user. The user who performs the registration operation on the intermediate platform 22 can allow it to perform network transaction operations. When the user registers by using the user name and password, etc., the user can also explain the payment method of the cash on delivery at the time of registration, so that the intermediate platform 22 can know the payment method of the user each time the user transactions. The merchant processing sub-unit 224 is configured to receive and process various interactions with the merchant including the merchant registration. The merchant processing sub-unit is configured to receive the merchant's registration request, process the merchant's registration request, and if the merchant's registration is to meet the registration requirements required by the platform, allow the registration and save the merchant's information. The transaction result can be transmitted back to the merchant through the merchant processing sub-unit 224 each time the merchandise is traded. The present invention may also be that the merchant logs into the intermediate platform 22 to query the current transaction status of each transaction through the merchant processing sub-unit 224. -14 - 201040863 Logistics platform processing sub-unit 225: for receiving and storing the contract information of the logistics company, receiving and processing various transaction information transmitted by the logistics platform in each transaction process, including receiving the contract result message and the user confirmation message respectively Transfer to the payment platform 22. Transaction processing unit 226: processes each transaction and saves the processing structure to first repository 222. The first database 222 is further divided into a user storage area 227 for storing user information, a merchant storage area 228 for storing business information, a logistics platform storage area for storing the contracted logistics company information, and storage for storage. The transaction data storage area of each transaction situation is 23 0. The payment platform 23 is used to complete the settlement of funds with various merchants and logistics companies. Depending on the connection mode of the payment platform 23 and the intermediate platform 22, the hardware composition of the payment platform 23 is slightly different. For example, if the payment platform 23 and the intermediate platform 22 are connected through the Internet, the payment platform 23 is provided with a network security device for network security, such as a firewall, if the payment platform 23 and the intermediate platform 22 are connected through a dedicated line. It does not need to set up a network security device. The payment platform 23 further includes a second server 231 and a second database 232, the second server 231 further comprising: an interaction processing unit 233 for processing interaction with the intermediate platform 22 > a clearing processing unit 234: for The setting is completed with each logistics platform 25 to perform regular or immediate liquidation operations. When the logistics platform 25 chooses to complete the clearing work on a regular basis, all the expenses including the payment, -15-201040863 freight and service fee in the current period will be transmitted by the logistics company to the payment platform 23 in advance, and then by the payment platform 23 The server after the pumping is cleared to the corresponding logistics company. The settlement processing unit 23 5: is configured to perform a periodic or immediate settlement operation with each merchant according to a preset. Each merchant can choose the settlement method according to the characteristics of the merchant and the transaction characteristics of the goods. For example, the merchant can select the payment platform 23 to transfer the cost of the transaction, the freight, and the freight to the account designated by the merchant after each transaction is completed. The second database 232 further includes: a merchant account storage unit 236 for storing the settlement with the merchant and storing each transaction and merchant settlement, and provisions for storing and logistics settlement and storing each transaction and logistics settlement. Logistics platform storage unit 23 7. The user processing sub-unit 223, the merchant processing sub-unit 224, the logistics platform processing sub-unit 225, and the transaction processing unit 226 are logical units integrated in the processor of the first server 22 1 , the clearing processing unit 23 4 and the settlement processing unit 235 is a logical unit that is integrated in the processor of the second server 231. In the above structure, the present invention provides a network transaction method. Referring to FIG. 3, the method is used for transaction of goods between a merchant and a user through a logistics company, which includes the following steps: s 11 〇: user The merchant's merchandise is purchased through the intermediate platform, and a transaction request including at least the user's selection of the cash on delivery transaction mode is transmitted to the intermediate platform. The merchant will place the goods that can be auctioned and their corresponding prices on the middle platform - 1640, 2010, 863. When the registered user logs in to the intermediate platform, the intermediate platform can know the price of the goods, the freight and the goods required to purchase the goods. All fees and payment methods including the service fee. When the user confirms that the item needs to be purchased, a transaction request is transmitted to the intermediate platform, the transaction request including at least the item information, the number of required payments, and the payment mode. If the user chooses the cash on delivery method, the transaction request also includes the address of the user's cash on delivery. S 1 20: The intermediate platform transmits the transaction 0 information including the cash on delivery transaction mode to the payment platform. When the intermediate platform receives the transaction request, it establishes the transaction record and transmits the transaction information (especially the payment method) to the payment platform, so that the payment platform creates the transaction. S130: The intermediate platform transmits the notification request of the on-site contract to the logistics platform of the contracted logistics company designated by the merchant or the intermediate platform. This step can be implemented by the following steps: First, the intermediate platform transmits the transaction request information to the merchant to the merchant, so that the merchant can know the transaction situation in time, so that the merchant can stock up as soon as possible. 〇 Next, the merchant transmits the information of the selected contracted logistics company to the intermediate platform; then, the intermediate platform transmits the notification request for the on-site contract to the corresponding logistics platform. This step can also be realized by the following steps: the intermediate platform directly transmits the notification request for the on-site contract to the logistics platform corresponding to the contracted logistics company pre-designated by the merchant. The logistics platform can find the location of the merchant by logging in to the intermediate platform, so that the logistics company can carry out the operation of collecting and collecting the logistics fee. The -17-201040863 invention may also include the address of the merchant in the notification request for the door-to-door contract transmitted by the intermediate platform. The notification request of the present invention includes at least the contracted merchandise information, all the fees spent on purchasing the merchandise, and the address of the user. The logistics company contracts with the intermediate platform in advance to sign the contracted logistics company. At each transaction, the merchant selects one of the contracted logistics companies to sign the logistics company to complete the transaction, or the logistics company contracts with the intermediate platform in advance to sign the contract. The logistics company, in advance, selects one of the contracted logistics companies from the contracted logistics companies as the logistics company designated by the merchant, and completes the transaction through the designated logistics company every transaction. S 1 40: After receiving the contract result message of “successful door-to-door success” transmitted by the logistics platform, the intermediate platform transmits the transaction status of the merchant's shipment to the payment platform. After the logistics company has come to the door, there are usually two kinds of results. One is “successful contracting” and the other is “unsuccessful door-to-door contracting”. After the “successful door-to-door contract”, the logistics company will transfer its contract results to the intermediate platform through the corresponding logistics platform. The intermediate platform will save the results of the contract, so that the merchants and users can make inquiries, and the transaction status of “successful door-to-door contract” Transfer to the payment platform. When the “on-site contract is unsuccessful”, the logistics company will also transmit the results of the contract to the intermediate platform through the corresponding logistics platform. The contract result may also include the reasons for its “unsuccessful door-to-door contract”, for example, If the transaction is rejected due to reasons such as stocking and unloading, the receiving platform will send the results of the contract to the payment platform and judge the merchant when receiving the news of the result of the “unsuccessful door-to-door contract” delivered by the logistics platform. Whether the number of "unsuccessful home orders" is greater than one domain, and if so, the merchants are processed according to preset regulations. For example, the intermediate platform can deprive the merchant of the eligibility to conduct transactions on the intermediate platform. s 1 50: After receiving the user confirmation message of “user confirmed receipt” transmitted by the logistics platform, the intermediate platform transmits the transaction status of the buyer that has confirmed the receipt to the payment platform. 0 When the logistics company delivers the goods to the user, a common situation is that after the user confirms and pays the money, the logistics company transmits the user's confirmation message to the intermediate platform through the corresponding logistics platform, and the intermediate platform transmits the transaction status to the payment. platform. Another common situation is that the user refuses to purchase, the logistics company also needs to send the message that the user refuses to purchase to the intermediate platform through the logistics platform. The intermediate platform not only needs to transmit the transaction status to the payment platform, but also needs to perform the following operations: The logistics platform returns a processing instruction message for returning the goods to the merchant, and the logistics platform returns the processing result of the goods to the merchant to the intermediate platform; the intermediate platform returns the processing result to the payment platform. S160: The payment platform and the merchant perform the transaction settlement of the transaction immediately or periodically. In this example, if the merchant considers that the fund is turned back faster, the payment platform receives the “user confirms the receipt”, and the payment and the freight are corresponding. The merchant conducts the remittance operation. Of course, the payment platform and the merchant can also periodically smear the fee settlement, and the payment platform will process the transaction for the transaction to the merchant. -19- 201040863 S 1 7 0 : The payment platform and logistics platform are either immediate or operational. The logistics company needs to first allocate the payment, freight, service platform, and post-payment platform to the company after the profit. If the intermediate platform and the payment platform belong to the non-fee, it is possible that the three companies are allocated according to profits. Payment platform settlement, according to the pre-agreed settlement between the two parties from the above transaction process, the logistics company pre-signing, the payment platform unified management of the logistics company, the problem of slow payment, for the user, in the present invention, The payment platform may also be referred to FIG. 4. It is another transaction system of the present invention, which includes a user 34, a merchant 31, and a logistics platform 35 of the intermediate platform 32.
