Description

Methods for trading pets on communication link}

The present invention relates to a method of trading pets through the Internet, and more specifically, to trade pets online, during a period in which a buyer can raise a pet before purchasing (hereinafter, 'pre-breeding period'). The present invention relates to a pet trading method of living with a pet and deciding whether or not to purchase and determining a pet's trading price in proportion to the prehistoric period.

We live in a society that is changing so fast that it is no exaggeration to say that we live in a new world different from yesterday. The beginning of the change is due to the information network called the Internet, created by the US Government's Advanced Research Projects Agency (ARPA) in 1969, which connects all the computers on the planet into one collective, The nations were born into one community life without local division. For example, we can meet the United States in just one second, when we had to fly more than 20 hours across the Pacific to arrive. It's the Internet that makes these things that seemed impossible before.

The change of society due to the Internet has a great influence on the economic life of the individual, for example, the shopping mall of the Internet. Like the shops that existed offline, an electronic store located in a communication network called the Internet is a shopping mall. Users can't touch the real thing of the product like an offline store, but instead the shopping mall is helping users to buy detailed descriptions and pictures. In addition, the development of IT technology allows a user to securely pay the price of goods purchased in various forms online, such as mobile phone payment, online deposit, credit card payment is a typical payment method that is performed online.

On the other hand, the user connects to the Internet using a computer provided at home. Then, a predetermined web navigation process or a URL directly known to the web browser is entered to find a shopping mall. In addition, the user accesses the shopping mall and purchases the goods online only after comparing the prices of the products to be purchased by comparing directly with various shopping malls or direct shopping sites. Then, the shopping mall delivers the purchased goods to the buyer by courier service.

However, even in a shopping mall that handles a variety of products, there is a field in which e-commerce is not activated due to the specificity of a product to be sold, which is a field of pet commerce related to the present invention. Due to its peculiarities, pets are not active in shopping malls. Therefore, to date, transactions through veterinary hospitals are common, and even if they are traded online, only a fraction of them are available.

In order to further promote pet transactions online, it is necessary to allow ordinary users who do not have the professional identification ability to buy goods by trusting the shopping mall. In addition, since online buyers are very sensitive to the price of goods, it is desirable to present an appropriate plan to allow the buyer to purchase a pet at a desired price.

The present invention was devised to solve the above problems, so that pets can be traded online so that purchasers can live with the pet during the prehistoric period in which the buyer can raise the pet before entering into a trading contract. The present invention is to determine and determine the transaction price of the pet in proportion to the prehistoric period.

In order to achieve the above object, the present invention provides a transaction system comprising: (a) personal information of a seller from a seller terminal; Types of pets; And selling price of the pet including the pre-order period: and selling the pet information on the sales information unit of the database unit. (b) providing the information of the pet to the plurality of buyers through the site provided by the transaction system with reference to the sales information contained in the sales information unit; (c) a new prehistoric meat period based on the prehistoric meat period presented by the seller; and the buyer's personal information; Receiving the purchase information of the buyer, including information on the pet to purchase; (d) determining the transaction price of the pet with reference to the difference in the prehistoric period presented by the buyer and the seller; And, (e) receiving the payment information of the buyer corresponding to the transaction price from the buyer; further comprises.

In addition, the pet transaction method through the communication network of the present invention, by sending the proof mail written on the basis of the purchase information and the sales information to the buyer and seller through the communication network, the copy of the proof mail of the database unit It is preferably configured to solve the legal problems that may occur after the transaction of the pet;

Preferably, in order to determine the transaction price of the pet, the method of hanging the pet through the communication network of the present invention, the step of obtaining the difference between the prehistoric period presented by the buyer and seller; Determining a discount rate based on the obtained difference in prehistoric meat duration; And modifying the selling price of the pet presented by the seller in consideration of the discount rate, so that the transaction price of the pet can be determined by the purchaser's selection.

On the other hand, the transaction system of the present invention, when receiving the purchase confirmation of the pet from the buyer terminal, operates to pay the seller the transaction amount received from the buyer. If there is no purchase confirmation of the purchaser within the prehistoric period, the trading system operates to refund the paid transaction amount of the paid pet to the purchaser. Therefore, the trading system of the present invention receives and stores the pet's sales amount from the buyer until the transaction is completed.

In addition, the transaction system determines whether there is a difference between the prehistoric period presented by the buyer and the prehistoric period presented by the seller with reference to the sale information of the same pet included in the sales information unit of the database unit, and determines that there is a difference. In this case, a web page indicating the change in the pet's transaction price caused by the difference is generated and output to the buyer's terminal to inform the buyer of the change in the transaction price.

Referring to FIG. 2, the seller drives the browser in the seller terminal 300. Then, the address (URL) of the site provided by the transaction system 100 of the present invention is entered in the search box or connected to the site through a predetermined web navigation (S110).

Then, the web server unit 110 of the transaction system 100 provides a site to the browser of the seller terminal 300 through the communication network 200. Subsequently, the seller inputs the authentication information obtained during the membership registration process into the received web page and requests the member to log in to the transaction system 100. The authentication information input by the seller is transmitted to the web server unit 110 through the communication network 200, and the member information of the seller included in the member information unit 161 of the database unit 160 is linked to the database unit 160. A login process for searching is performed (S120).

In step S120, the seller who obtains the use of the site surfs the site provided by the trading system, and in this process, the trading system 100 receives various requests from the seller through a web page. In order to process the user's request, the transaction system 100 forwards and processes the user's request to each component in a web programming language, and each component is the web server unit 110. Through the process to provide the processing result of the web page format to the seller terminal (S130).

In step S130, the seller receives a web page as shown in Figure 3 from the transaction system 100, the web page 30 may enter the sales information of the pet to be sold by the seller in the transaction system 100 Make sure

As shown in FIG. 3, the web page 30 received by the browser of the seller terminal 300 includes an area 31 for describing seller information; An area 32 for describing transaction information; An area 33 for explaining the transaction method; And an area 35 for registering information about pets for sale. On the other hand, the seller information described in the area 31 is preferably configured to be extracted from the member information obtained in the member login process (S120) of the seller, the price planning unit 130 is the authentication information received from the seller in step S120 Search for the member information unit 161 of the database unit 160 using. As a result, member information corresponding to the authentication information is parsed from the member information unit 161, thereby forming an area 31.

In addition, the transaction information in region 32 includes a prehistoric meat period; Sale Price; Payment method; includes. Area 33 is an area for explaining the transaction method. Since the transaction by the prehistoric meat period according to the present invention is a transaction method that is unfamiliar to the buyer or seller, it is the area of the reference number 33 for the purpose of informing the parties before the transaction, and the next process can be performed only by clicking the confirm button 34. So that the seller knows how to trade.

Finally, area 35 allows the seller to register information about the pet to sell, which includes a picture of the pet; Species of pet; Number of months after birth; Gender;

Then, the price planning unit 130 of the transaction system 100 stores the sales information received in association with the database manager 150 in the sales information unit 163 in the database unit 160 (S160). In this case, the price planning unit 130 may set a flag indicating that the stored sales information is based on the prehistoric meat period.

4 illustrates a process in which a buyer searches for sales information of a pet registered on a site and purchases a pet.

The buyer accesses the transaction system 100 using the seller terminal 400 in the same manner as in steps S110 and S120 of FIG. 2, and performs a member login process (S210). In operation S220, the purchaser who obtains the use right inputs (or selects) a search keyword to the site, and requests a search for a pet being sold to the transaction system 100 through the communication network 200 (S220). ).

The input search keyword is transmitted to the transaction list creation unit 120 associated with the web server unit 110. Then, the transaction list creation unit 120 refers to the sales information unit 163 in the database unit 160 with reference to the received search keyword. At this time, it is preferable to refer to a flag indicating whether or not the transaction by the prehistoric period of the various fields of the sales information unit 163, but the present invention is not limited thereto. The details of information stored in the sales information unit 163 are as described above. The transaction list generator 120 creates a list according to a predetermined format with the searched result and provides the list to the web browser of the purchaser terminal 400 through the communication network 200 (S230 and S240).

In step S250, the buyer searches the received search list, and if the pet is found to be interested, the character string including the object linked with the sales information contained in the sales information unit 163 of the database unit 160 may be moved with a mouse. Click to ask the trading system 100 for detailed information about the pet. Then, the transaction list creation unit 120 of the transaction system 100 parses the detailed information about the pet from the corresponding sales information in the database unit 160, constructs a web page according to a predetermined format, the buyer terminal ( 400) to the browser. By repeating this process, when the buyer finds a pet to purchase from the search list, the buyer is provided with a web page 40 as shown in FIG. 5A (S250 and S260).

Referring to FIG. 5A, the web page includes an area 41 in which information about a pet to be purchased is displayed; An area 42 listing information relating to the buyer; An area 43 for selecting a prehistoric meat period; And an area 44 for explaining the transaction method. The prehistoric meat period described in the area 43 is selected by the buyer corresponding to the prehistoric meat period presented by the seller. The price planning unit 130 calculates the period of prehistoric meat which can be selected by the buyer by referring to the sales information of the pets in the sales information unit 163 of the database unit 160 and selects the area of reference number 43 as a drop-down box. It can also be configured.

Referring back to FIG. 4, the buyer inputs necessary information in each area of the received web page, and clicks an input button 45 provided on the web page to transmit the purchase information to the transaction system 100 (S270). .

The price planning unit 130 having received the purchase information checks whether there is a difference between the prehistoric period presented by the seller and the prehistoric period presented by the buyer before storing the purchase information in the database unit 160 (S280). ).

If there is a difference, the pricing unit 130 prepares a web page as shown in FIG. 5B and outputs it to the browser of the purchaser terminal 400. Figure 5b shows an example of a web page for explaining to the buyer the change in the transaction price changes due to the difference in the prehistoric meat period.

Referring to FIG. 5B, the web page 50 includes an area 51 for describing a trading method in detail; and an area 52 for explaining a change in price caused by a difference between prehistoric meat periods. The price planning unit 130 receives the purchase information of the purchaser through the web page 40 output to the browser of the purchaser terminal 400. Then, the price planning unit 130 compares the received purchase information with the database manager 150 in conjunction with the sales information corresponding to the purchase information contained in the sales information unit 163 of the database unit 160, and as a result, The information of reference numerals 521, 522, 523, 524, 525 described in the region 52 is obtained. The reference numeral 521 is a prehistoric meat period designated by the seller, and the reference numeral 522 is a prehistoric meat period determined by the buyer.

And, reference numeral 523 is a difference between the prehistoric meat period presented by the seller and the buyer. The discount rate is calculated on the basis of the difference in the prehistoric meat period. In the present invention, the discount rate is obtained by various methods. First, the discount rate is not just a discount, but also a premium. That is, the discount rate obtained when the prehistoric meat period presented by the buyer is larger than the prehistoric meat period presented by the seller increases the transaction price of the pet. In the opposite case, the pet's transaction price is lowered by the discount rate. On the other hand, the discount rate can be calculated in units of one day, by adding a discount rate of 1% per day can be set as the discount rate period corresponding to the difference between the prehistoric meat period. For example, if the difference in the length of prehistoric meat obtained is 5 days, the discount rate is 5%. Alternatively, you can set the discount rate as the period increases, such as 1% on the 1st day, 2.5% on the 2nd day, and 4.5% on the 3rd day. In addition, reference numeral 525 shows a final transaction price of the pet calculated by applying the discount rate obtained in reference numeral 524 to the selling price suggested by the seller.

The price planning unit 130 outputs the obtained information as a web page through the web server unit 110 according to the format of the web page illustrated in FIG. 5B and provides it to the purchaser's terminal 400 (S290).

On the other hand, if it is determined that there is no difference in the prehistoric period, the price setting unit 130 stores the received sales information in the sales information unit 163 of the database unit 160 and ends the step.

FIG. 6 illustrates a process in which the transaction system 100 transmits a content proof mail containing the contract contents to the contracting party when a transaction is made between the buyer and the seller.

The buyer transmits the purchase information to the transaction system 100 through the communication network 200 through the process as shown in FIG. 4, and the transaction amount of the pet (the amount presented by the seller if there is no difference in the pre-breeding period, or the line). One of the amount newly calculated by the difference in breeding period) is paid to the trading system (S310). The purchaser transmits a request of a web page for entering payment information using the purchaser terminal 400 to the trading system 400, and the trading system 400 selects from among various types of web pages according to the requested payment method. Any one (eg, ARS payment, credit card payment, mobile phone payment, etc.) is output to the purchaser terminal 400. Then, the buyer fills in the necessary information on the received web page, and transmits it to the transaction system 100 to pay the purchase price of the pet.

At the same time, the purchaser marks the web page received in step S310 indicating whether to issue the content proof mail and transmits the same to the transaction system 100 as the payment information.

Then, the proof mail sending unit 140 checks whether there is a request for sending the proof mail from the buyer (S320), creates the proof mail according to a predetermined form, and writes the web page 60 containing the buyer terminal. The transmission to 400 (S330).

Figure 7 shows an example of a web page containing a content proof mail according to the present invention. Referring to Fig. 7, this webpage 60 includes an area 61 representing a trading party; An area 62 displaying a transaction object; An area 63 displaying a contract relationship; And an area 64 displaying transaction terms.

On the other hand, the content mail sending unit 140 in conjunction with the database management unit 150 using the information (161, 162, 163) contained in the database unit 160, the web containing the content mail in the format shown in Figure 7 The page is configured and output to the browser of the purchaser terminal 400 through the communication network 200.

The purchaser checks the proof mail displayed on the browser and clicks the consent button 66 provided on this web page (S340). Then, the proof mail sending unit 140 stores the copy in the proof mail information unit 164 of the database unit 160, and stores contact information (e.g., e-mail) of the buyer and seller included in the member information unit 161. And mailing the proof of contents with reference to the address (S350). If the user does not want to send the proof mail, the purchaser can cancel the issuance of the proof mail by clicking the cancel button 67 provided on the web page.

Subsequently, the transaction system 100 notifies the seller using a means such as an e-mail or a telephone that the transaction for the pet is in progress. The seller then delivers the pet to the buyer. The buyer receives the pet from the seller to look through the prehistoric period, and determine whether to purchase or not to the trading system (100). The buyer can inform the trading system of the confirmation of the purchase in a variety of ways, which can be done via e-mail, telephone or site. Accordingly, when the pet's transaction is normally terminated or the purchase is rejected, the buyer returns the pet to the seller, and the transaction system refunds the amount of the deposit to the buyer.
