System and method for buyer-driven conditionalpurchase offers using communications network}

The present invention relates to a reverse auction system and method, and more particularly, to broker a reverse auction of a product using a multi-communication network so that a product transaction can be made through a reverse auction system between a seller and a buyer located in an adjacent region. The present invention relates to a reverse auction system and method using a communication network.

The trading method of goods is getting better day by day. The most basic trading method is a method in which a buyer visits a store and purchases a desired product when purchasing a product. In this case, since the seller is unilaterally presenting the product, the buyer has to visit many stores and collect information to select the product in order to obtain a product that satisfies the condition that the buyer wants. have.

Thus, a new way of trading called auction has emerged, which refers to oral trading as a result of competition. That is, when a seller presents a product, a plurality of buyers who want to purchase the product may gather to purchase a product according to a desired condition through competition, and this process may take a relatively short time. However, since the quantity of the goods sold is mostly limited, there is a problem that the buyer may miss the opportunity to purchase the goods.

To compensate for this, a reverse auction was introduced, which means that the role of the seller and the buyer in the general auction method is changed. When the buyer presents the conditions for the product he wants to purchase, a number of sellers selling the product The bidder, among which the buyer bids a product that meets the desired conditions. Unless there is a single seller who bids, most buyers can purchase the desired product that meets the requirements, and the time and effort required for this can be reduced.

Nowadays, with the development of the Internet, these reverse auctions are made through reverse auction sites that can participate anytime and anywhere. However, if you buy and sell using the reverse auction site, you can't check the products yourself until most of them pay for the winning bid, so if you don't like the buyer after receiving the goods, Waste of shipping costs may occur. This problem can be even worse when buyers and sellers are remote from each other, and there is a possibility of fraudulent misuse of the fact that the product can be identified after payment.

In addition, most conventional reverse auction sites store price information on goods and services in a database, and when a buyer requests reverse auction bidding, a site for reverse auction bidding is provided with price information based on the information stored in the database. Rather than price comparison site. However, the present invention, which will be described below, provides a real-time reverse auction method service by providing real-time bidding request information to a seller when a buyer requests a product and a service reverse auction bidding in real time by bidding a product that meets a customer's needs.

The present invention has been made to solve such a conventional problem, so that the seller and the buyer can easily face when the bidding product is a successful bid, the buyer directly checks the product before paying the goods price to close the deal It is an object of the present invention to provide a reverse auction system and method using a communication network that can determine whether to determine whether, and to prevent the occurrence of fraud behavior by using the point of checking the goods after payment of the goods.

In order to achieve the above object, the reverse auction system using the communication network according to the present invention includes a reverse auction device including a database, a web server, and a trading brokerage unit.

The database stores buyer information including the region information where the buyer is located and seller information including the region information where the seller is located, and the web server communicates with the buyer's user terminal (buyer's terminal) and the seller's user terminal (seller's terminal). And outputs the product request information received from the buyer terminal to the trading brokerage unit, and notifies the seller terminal of the registration of the product request information according to the seller information inputted from the trading brokerage unit. In addition, the trading broker receives the product request information, reads the buyer's local information, and outputs the seller's information of the seller located in the region adjacent to the buyer to the web server.

With this configuration, the seller and the buyer can easily face each other in the event of a successful bid, so that the buyer can check the product directly before making a payment and decide whether or not to close the deal. This can prevent the occurrence of fraud behavior.

Here, the product request information includes information related to the product that the buyer wants to request and information of the buyer requesting the product, the information of the buyer of the product is not disclosed to the seller at the time of sending the product request information to the seller terminal, It can only be revealed to winning sellers. Therefore, it is possible to prevent the leakage of personal information of the buyer.

The terminal notifies the terminal in real time, and the SMS processor notifies the seller terminal of registration of the product request information received from the buyer terminal using a short message service (SMS).

Then, the mail processing unit notifies the seller terminal of the registration of the product request information received from the buyer terminal using an e-mail in real time, and the bulletin board management unit manages the bulletin board that posts the transaction status in real time during the reverse auction.

With this configuration, since the reverse auction transaction status can be transmitted to the buyer and the seller in real time regardless of the type of the buyer and the seller terminal, the seller can enable real-time bidding, and the buyer can compare a plurality of bidding product information. This allows the buyer to purchase the optimum product desired by the more favorable conditions and prices.

In addition, information such as auction end time, current remaining time, and the total number of bidders can be checked in real time, so that buyers and sellers can conclude the best deal through the establishment of an auction strategy.
