The following describes the bidding and auction process in more detail.

In the embodiment of the present invention, after securing the salable goods, the bidding announcement for the goods is made online or offline before the bidding is started. Accordingly, the buyers can access the intermediary system 2 through various paths. You will bid.

3 sequentially illustrates a process of registering a bid through the Internet in an electronic commerce system according to an embodiment of the present invention.

As shown in the accompanying FIG. 3, when the purchaser runs a program (for example, a web browser) for network connection on the terminal 3 and inputs a URL for connecting to the intermediary system 2, This URL information is converted and packetized by a hypertext transfer protocol (HTTP) in a web browser and then transmitted to the intermediary system 2 via the network 1.

Accordingly, the interface server 10 of the mediation system 2 transmits the web page corresponding to the URL information to the purchaser terminal 3, and the transmitted web page is converted into a window state on the web browser and displayed. Therefore, the buyer confirms various information provided by the mediation system 2 through the web page displayed on the screen of the terminal 3 (S100).

Thereafter, when the interface server 10 of the intermediary system 2 provides a screen for member authentication to the purchaser terminal 3 to which the interface server 10 is connected, and the buyer ID and password are transmitted from the purchaser terminal 3, the processing server 4 The user authentication unit 310 performs member authentication according to whether the transmitted buyer ID and password are stored in the member database 427 (S110).

When the purchaser authenticated as a member or a purchaser who is not authenticated requests a product information, the bid registration unit 320 of the processing server 30 connects the purchaser's terminal 3 to a page providing the corresponding product information. To check the information about the article you want to bid (S120 ~ S130).

Here, for each category, for example, communication information, audio equipment, beauty, living furniture, health goods, etc., a variety of goods are provided for each category, item code of each item, bid high and low prices, bid participation fee, etc. To help buyers set an appropriate bid.

When the buyer selects a specific item and inputs a bid, the bid registration unit 320 first determines whether the bid is within a setting range, that is, the bid highest price and the lowest price range (S140 to S150), and the bid price is included between the lowest price. If it is determined whether the number of bids of the buyer for the article exceeds the set number of times (S160). If it is determined that the bid is not included in the highest price and the lowest price range or the number of bids exceeds the set number of times, the purchaser's terminal 3 notifies that the bid for the corresponding item is impossible (S170).

On the other hand, if the bid is included in the highest price and the lowest price range and the number of bids does not exceed the set number of times, it is determined that bidding is possible, and the payment processing unit 340, for example, the payment information for payment at the time of successful bid, for example, credit card Request a number (S180). Accordingly, when the buyer enters the payment information, the payment processing unit 340 provides the input payment information to the payment system 4 to request the approval of use, and the payment system 4 provides the payment information, for example, a credit card number. The approval process is performed by reviewing the available period for the service, whether the payment is overdue (S190 ~ S210).

If it is determined that the payment information is not available as a result of the approval, the bid registration unit 320 notifies the purchaser's terminal 3 of the impossibility of bidding (S220 to S230), and if it is determined that the payment information is available, the buyer In accordance with the presence or absence of a bid participation fee for the bidding item, the payment processing unit 340 processes the bid participation fee. That is, when there is a bid entry fee for the bidding article, the payment processing unit 340 provides the payment information and the bid entry fee to the payment system to request payment approval, and the payment system 4 applies the bid entry fee based on the payment information. Process payment approval for (S240 ~ S260).

However, if the purchase limit is exceeded and the payment is not approved, the bid registration unit 320 notifies the bidder to the buyer terminal 3, and if the payment is approved, the bid registration is performed (S270 to S280). That is, according to the bidding code of the item in the bidding database 423, the purchaser ID if the buyer is a member, and the buyer's social security number if the buyer is a non-member, such as the buyer's information, It stores bids, bid dates, payment information and the like, and updates the number of bids of the buyer to limit the number of bids for the same item of the buyer.

On the other hand, if there is no bid participation fee for the goods bid in step (S240), the bid registration unit 320 registers the bid information of the buyer in the bid database 423 without a separate payment process.

In this way, the buyer may bid through the Internet, or the buyer may bid through the telephone network based on a bid notice distributed through offline.

4 illustrates a process of registering a bid through a telephone network in an electronic commerce system according to an exemplary embodiment of the present invention.

When the buyer confirms the bidding announcement of the goods disclosed in the daily newspaper or the like and connects to the telephone network through the landline or the mobile communication terminal, the call center 20 requests the bidding information to the purchaser terminal 3 through the ARS. (S300 to S310).

On the other hand, the call center 20 is connected to the counselor through the buyer terminal (3) according to the buyer's choice to allow the buyer to bid through a conversation with the counselor, and may also be provided with bid information from the buyer through the ARS.

When the buyer provides a bid while providing a commodity code disclosed in a daily newspaper or the like (S320), the call center 20 provides the commodity code to the processing server 30 to inquire whether bidding is possible (S330). Accordingly, the bid registration unit 320 of the processing server 30 searches the bidding database 423 based on the item code to determine whether the buyer's bid for the item falls within the highest and lowest ranges and whether the number of bids exceeds the set number of times. The determination result is transmitted to the call center 20 (S340 to S350), and the call center 20 determines that the bidder is not included in the highest price and the lowest price range or the bid number exceeds the set number of times. Notice that it is impossible to bid for the item in the (S360).

On the other hand, if the bid is included in the highest price range and the lowest price range, and the number of bids does not exceed the set number of times, the payment processing unit 340 requests the payment information for the subsequent successful bid payment (S370), accordingly the call center 20 ) Requests the buyer for payment information, and when the buyer provides the payment information, the call center 20 transmits the payment information to the processing server 30 (S380 to S400).

The payment processing unit 340 of the processing server 30 transmits the payment information provided from the call center 20 to the payment system 4 to request the use approval (S410 to S420), and the corresponding payment information is not available as a result of the approval. If it is determined that the call center 20 does not notify the bidder to the buyer terminal (3) (S430 ~ S440). If it is determined that the corresponding payment information is available, the payment processing unit 340 of the processing server 30 processes the bid participation fee by the payment processing unit 340 according to the presence or absence of a bid entry fee for the item bidder (S450). S470), when the purchase limit is exceeded and the payment is not approved, the call center 20 notifies the purchaser terminal 3 of the impossibility of bidding (S480 to S500). When the payment is approved, the bid registration unit 320 of the processing server 30 stores the bid information including the bid corresponding to the item code of the article in the bid database 423 to register the bid (S510), call center ( 20) notifies the successful bid to the purchaser terminal (2) (S520).

In this way, the buyer can make a bid through various networks such as the Internet (including wireless Internet) or telephone network.In the bidding process described above, the buyer can make a bid again by inducing other payment information after notifying the bidder. Can be. Here, bid registration is performed after the bid entry fee is paid first. However, if payment information is available, the bid entry fee may be paid after the bid registration.

Next, the mediation system 2 performs a successful bidding process based on a plurality of bidding information. 5 illustrates a process of finally winning a bid in an electronic commerce according to an embodiment of the present invention.

As shown in FIG. 5, the successful bid processing unit 330 checks whether the bid period has elapsed, and if the bid period has ended, performs a successful bid process based on the bid information stored in the bid database 423.

The bidding price is selected from the highest bid among a plurality of bidding information stored for each item code in the bidding database 423, and a plurality of bids are bidded according to the sellable quantity set in the corresponding goods (S600 to S610). In other words, when the number of items available for sale is five, five bids are sold in order from the highest bid among a plurality of bids for the goods. On the other hand, if the same bid exists, the bid date is bid early by comparing the bid date of the bid, and when the two or more bids presented by one buyer is successful at the same time bid the lowest bid to the buyer.

As such, when a successful bidder is selected for each item, the successful bidder processing unit 330 may notify the successful bidder to the purchaser's terminal 3 through the mail server 50 or the like, and may also notify the successful bidder through an offline mail or the like. (S620). On the other hand, in the present embodiment, even after the successful bid, the price bid for each item is not disclosed.

The buyer who is notified of the successful bidding provides the final purchase intention to the mediation system 2, and the payment processing unit 340 provides the payment system with the amount corresponding to the bid presented by the buyer and the payment information when the buyer wants to purchase the successful bidding product. (4) provides a request for payment (S630 to S660). When payment of the payment system 4 is made, the payment amount, payment date, payment number, etc. are stored in the payment database 426, and then the information is found from the goods database 421 about the delivery system for delivering the goods. Requests for delivery by providing information such as an item code, a delivery address, and a delivery date to be delivered to the corresponding delivery system 5 (S670 to S680). In this case, the delivery system 5 may be a supplier that substantially supplies goods, or may be a delivery company that performs delivery only by receiving goods from a supplier.

On the other hand, if the purchaser gives up despite the successful bidder in step S640, the payment processing unit 340 pays and collects a penalty fee (for example, about 5% of the price of the goods) based on the purchaser's payment information (S690). .

As described above, according to the present invention, the buyer may access the brokerage system through the network and receive information on the goods to be bid directly, and may receive the information on the goods to be bid via offline and bid through the telephone network.

In addition, multiple bids may be made for a single item, and even if the bid is duplicated, the bidder may increase the bidder's participation degree even more because the bid is lowered.

On the other hand, in the present embodiment, the successful bidding processing unit 330 stores the bidding information of a plurality of buyers that are not successful for each item in the non-successful database 425, and subsequently for each buyer based on the information stored in the non-successful database 425. The total amount of the bid participation fee is calculated, and a part of the bid participation fee is issued to the buyer by issuing the coupon as a coupon for purchasing the goods at a price that is set for one item rather than the auction method. Here, the coupon includes all the reward means of various forms such as mileage, cyber money, cash, discount vouchers.

In particular, it is possible to grasp the characteristics of the items that the buyer bids to identify the purchaser's purchase pattern, and based on the purchase pattern, provide the buyers with the corresponding product information to induce a purchase intention or select a product that can bid. It may also improve the bid participation.
