[0002] With the development of modern society, the transaction form has gradually evolved from the original face-to-face transaction to the online and offline multi-channel transaction mode. When online transactions become the main way for people to trade, it is particularly important to build a fair and just transaction intermediary system;

[0003] In traditional transactions, information matching mainly relies on manual search and screening, which is extremely inefficient. With a large amount of commodity supply information and purchase information scattered around, it is difficult for buyers to quickly locate suitable sellers, and it is also difficult for sellers to accurately match target buyers, resulting in a long transaction cycle. Furthermore, payment security during the transaction process lacks effective protection, and order management is not transparent and convenient enough. In response to the above technical defects, a solution is proposed. Summary of the invention

[0047] In order to enable those skilled in the art to better understand the technical solutions in one or more embodiments of this specification, the following will be combined with the drawings in one or more embodiments of this specification to clearly and completely describe the technical solutions in one or more embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on one or more embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this document.

[0048] System Example

[0049] According to an embodiment of the present invention, a trading system is provided. Figure 1 A schematic diagram of a trading system provided in one or more embodiments of this specification, such as Figure 1 As shown, the trading system according to the embodiment of the present invention specifically includes:

[0050] Supply and demand matching module 10: used to obtain supply and demand information published by buyer or seller users, including commodity supply information and commodity purchase information, and match the commodity supply information and commodity purchase information based on the supply and demand information;

[0051] Order generation module 12: when the commodity supply information and commodity purchase information are successfully matched, the matching success information is sent to the user who published the commodity supply information and the user who published the commodity purchase information, and after obtaining the confirmation information from both parties, a transaction order is generated according to the obtained buyer and seller information and commodity information;

[0052] Transaction module 14: used to obtain the payment amount of the transaction order and call the third-party transaction platform to complete the payment according to the payment method selected by the buyer user;

[0053] Transaction tracking module 16: used to obtain the outbound and transportation information of the goods uploaded by the seller after obtaining the payment completion information, update the order status in real time, and complete the current order transaction after obtaining the buyer's goods receipt information.

[0054] The system also includes a user management module, including a login registration unit and an account management unit;

[0055] The login registration unit is used to: provide a user with user login information to log in to the trading system; provide an information registration interface for a first-time user, guide the user to select an identity, the identity is a buyer or a seller, fill in the relevant registration information after the selection is completed, assign a unique ID to the user according to the registration information filled in by the user, and store the user's registration information and ID in the user database, each ID corresponds to an account;

[0056] The account management unit includes a user database for storing user registration information and account IDs, and classifying and rating accounts according to account behavior, including buyer members, seller members, and member rating. For example: for buyer members, first of all, in terms of transaction amount, different levels are set to correspond to different amount ranges, and the higher the consumption, the higher the level; in terms of transaction frequency, members with frequent purchases and short interval purchases have better levels; those who have registered for a long time and actively participate in activities will have their levels increased accordingly. For seller members, in terms of sales performance, sellers with higher cumulative sales and higher average unit prices have higher levels; sellers with a large number of products on the shelves and a high sales frequency have higher levels; sellers with a high praise rate have higher levels; sellers with a short after-sales service response time have higher levels.

[0057] The system also includes an information publishing module, which is used by sellers and buyers to publish commodity supply information and commodity purchase information based on their own needs. Specifically: after the seller user logs in to the system, he publishes commodity supply information through the commodity publishing interface. The commodity supply information includes commodity category, such as electronic products, household goods or food, name, specifications, such as clothing size, electrical appliance power and other information, which explains the physical properties of the commodity such as size, model, capacity, description, allowing the seller to explain the function, characteristics, material, etc. of the commodity in detail, price and inventory; after the buyer user logs in to the system, he publishes commodity purchase information through the commodity publishing interface. The commodity purchase information includes commodity category, name, conditions and budget price range. The condition part may include the newness, quality standards, brand requirements and other contents of the commodity, such as purchasing new and unopened commodities or products of a specific brand. The setting of the budget price range provides a price reference for the seller, allowing the seller to judge whether its own commodities meet the buyer's expectations, and also avoids the two parties wasting time communicating due to excessive price differences; the published commodity supply information and commodity purchase information are all stored in the commodity supply and demand information database, and are classified and stored according to commodity category, publishing time, etc.

[0058] When a buyer publishes a product purchase request, the system will match and filter the stored product supply information according to the information stored in the product supply and demand information database to find the seller's needs that match the product he wants to buy, so as to actively contact the seller and promote the transaction. When a buyer publishes a product purchase request, the system will immediately start the matching process. First, a preliminary screening is performed based on the product category, and all product supply information belonging to the category is extracted from the product supply and demand information database. For example, if the buyer is looking to buy "sports equipment-basketball", the system will filter out all basketball-related supply information. Next, the product name is accurately matched to exclude those supply information with inconsistent names, further narrowing the scope. Then, the product condition requirements are deeply analyzed. For example, if the buyer requires a "new and unused" basketball, the system will exclude the supply information of second-hand basketballs. Finally, check whether the budget price range matches the price in the supply information. If the seller's price is within the budget range set by the buyer, the price match is considered successful. After this series of matching and screening, the system will present the seller information that meets the requirements to the buyer. The buyer can actively contact the seller based on this information and start transaction negotiations, such as asking about product details, logistics methods, after-sales service, etc., to promote the completion of the transaction.

[0059] The system also includes an information review module, which is used to review whether the information posted by users is true and legal, including:

[0060] For seller users, the platform will review whether the product categories in the published product supply information meet the platform requirements, whether there are any errors in the product name, whether it is an item allowed to be traded, whether the product specifications are reasonable, whether there is any false content in the product description, and whether the product price is reasonable; for the review of seller users' product supply information, the platform will determine the acceptable categories based on its own positioning and business scope. For example, a professional digital platform only allows the release of electronic digital products. If clothing categories appear, it does not meet the requirements; the product name review is accurate and clear, with no typos or vague expressions, and at the same time ensures that it is not an item prohibited from trading by the platform, such as banned drugs cannot appear in the product name; the product specification review checks whether it meets industry standards and actual logic, such as the mobile phone memory specifications should be within a common numerical range; the product description review eliminates false propaganda and prevents exaggeration of efficacy or concealment of defects; the price review refers to market conditions and costs to determine whether there is unreasonable pricing that is too high or too low. For example, an ordinary mobile phone with a price that is several times higher than similar products on the market or as low as below cost is not allowed.

[0061] For buyers, we review whether the conditions and requirements in the published product purchase information are clear and whether there is any content that violates the platform rules. When reviewing the product purchase information of buyers, the focus is on the conditions and requirements. They must be clear and specific. For example, if you want to buy a computer, you should specify whether it is a desktop or a laptop, and the general configuration requirements, etc., to avoid ambiguity that makes it difficult for sellers to judge. At the same time, we strictly review whether there is any content that violates the platform rules, such as proposing illegal or unethical additional transaction conditions, such as requiring sellers to provide pirated software, and purchasing items that are not allowed to be sold.

[0062] When a seller user publishes product supply information, the information stored in the product supply and demand information database is matched and screened with the stored product purchase information to find buyer needs that match the products they supply, so as to actively contact the buyer and promote the transaction. Similarly, when a seller user publishes product supply information, the system will also perform similar matching operations. Starting from the product category, all relevant product purchase information is found, and then accurate matching is performed based on the name, conditions, etc. For sellers, the focus is on the buyer's condition requirements, such as the buyer's expectations for product specifications and quality, as well as the budget price range. Once a matching buyer demand is found, the seller can actively contact the buyer, introduce the advantages and features of the product, answer the buyer's questions, and negotiate transaction details, such as discounts for bulk purchases and delivery time, thereby increasing the possibility of a successful transaction. This two-way matching and screening mechanism greatly improves the docking efficiency of both parties to the transaction, reduces the time cost of information search, enables more accurate docking of product supply and demand, and activates the entire transaction market.

[0063] When the product supply information and product purchase information are successfully matched, the system will automatically push the matching information to the corresponding sellers and buyers. Sellers will know that potential buyers are interested in their products, and buyers will also know that they have found a supply source that meets their needs. After receiving the information, both parties can further view each other's detailed information, such as the seller's store reputation, the buyer's purchase evaluation, etc., to confirm whether they are willing to trade. If both parties confirm that there is no error, the order generation module will generate a formal transaction order based on the information obtained from the buyer and seller, including name, address, contact information, and specific information of the product such as category, specification, price, etc.

[0064] The system will calculate the payment amount of the order through the transaction module, which usually includes the product price, possible shipping costs and other related fees. After the buyer confirms the order, he chooses the payment method according to his own preferences. The system will seamlessly connect to third-party transaction platforms, such as Alipay and WeChat Pay, and call the corresponding interface to complete the payment process. During the payment process, the system will ensure the secure transmission and accurate processing of payment information, and at the same time feedback the payment status to the buyer, such as payment success, payment failure or waiting for confirmation.

[0065] Once the payment is successfully completed, the seller will receive a notification and start to handle the shipment of the goods, uploading the shipment and transportation information of the goods, including the name of the courier company, the courier number, etc. The transaction tracking module updates the order status in real time based on this information, from "paid, waiting to be shipped" to "shipped, in transit", so that the buyer can track the transportation of the goods at any time. When the goods are delivered to the buyer and the buyer signs for them, the system obtains the signature information, updates the order status to "completed", and completes the current order transaction.
