Description

ESCROW Transaction Providing System and Method With an Price Input Panel}

The present invention relates to a system and method for providing an escrow payment means using a transaction amount input window, and more particularly, to provide an escrow payment means to a product sales bulletin board operated by a website operated by a community or a naver. In consideration of the volatility of the final amount of the transaction product generated in the transaction environment between the person using the escrow payment method, the price changed without the cumbersome payment amount modification work that requires the seller to re-register the original sale price at the changed price. The present invention relates to a system and a method for providing an escrow payment method using a transaction amount input window that enables a buyer to make a payment immediately.

With the development of the Internet, commodity trading through the Internet is actively being performed. Merchandise trading over the Internet saves shopping time by allowing users to select, order, pay, and even deliver goods over the Internet, either from the company's computer or at home without having to visit the store. There are many advantages, such as being able to compare different products. One of the most important considerations for consumers in the trade of goods over the Internet is payment.

One of the safest ways to trade and pay for goods over the Internet is through the escrow system. A typical example is an auction site, which has a considerable difficulty in terms of cost and management in terms of building and operating such an escrow payment system.

In order to overcome these difficulties, companies have been specializing in providing only escrow payment means to small sites managed by the community. A typical example is the site www.unicro.co.kr, and the company entered into an agreement with the camera club site www.pentaxclub.co.kr, and then a member of the club site www.pentaxclub.co.kr When selling, escrow is provided as a means of payment.

However, there is a difficulty in using the escrow payment method or the system of the site www.unicro.co.kr. This means that an agreement between the sites and the site is available for escrow between members. For example, www.unicro.co.kr and www.pentaxclub.co.kr require preliminary agreements and system integration before pentaxclub members can use unicro's payment method.

For example, if an operator who operates a camera café site in Naver wants to use the unicro escrow payment system, there is a problem that can be used only when Naver and unicro have to negotiate. In addition, in the conventional method or system, when a seller wants to sell several items at the same time, there is a problem in that a post must be written for each individual item.

However, the present invention (application number: 10-2007-0111702) is provided based on the form of transactions between individuals and not individuals versus companies. Here, when looking at the transaction between the individual and the individual, the seller and the buyer often go through the process of adjusting the sales amount of the product through a mobile phone before the transaction is confirmed.

Therefore, a price adjustment occurs through the above process, and in order for the buyer to proceed to the final transaction according to the changed price, that is, to make a payment, the seller has to modify the cumulative payment amount that requires re-registering the initial sale price to the changed price. There was a problem that had to go through.

In addition, after the price negotiation through the mobile phone, etc. between the seller and the buyer is made, even if the final transaction amount is confirmed, if the seller is not in a situation that can directly access the Internet, the correction can not be carried out immediately. Therefore, the buyer has to wait for the correction work to be made, and eventually there was a problem that the product transaction progress is delayed.

The present invention has been made to solve the above problems, the object of the present invention can be provided to the buyer by copying and copying to the desired location by the individual to create an escrow payment window without prior consultation between the sites In the event that the price changes through the product purchase price negotiation process, payment can be made immediately according to the final price without the hassle of modifying the price of the product. It is to provide a method of providing an escrow payment method using the transaction amount input window to enable the transaction process.

2 is a flowchart illustrating a flow of a method for providing an escrow payment method using a transaction amount input window according to the present invention. Referring to Figure 2 will be described with respect to the escrow payment flow chart using the transaction amount input window according to the present invention.

(1) The seller signs up for a secure transaction site 20. (S100)

The secure transaction site 20 requires the following information to be inputted by a member who wishes to register (ie, a seller and a buyer) to pay for a product using the payment window button 70.

That is, information including social security number, name, ID, password, email, mobile phone number, telephone number, address, interest tag, payment bank, account holder, account number, SMS service reception, email service reception and adult block. The seller information is only one example of a database (DB) necessary for generating a payment window, and may be added or omitted if necessary.

(2) The secure transaction site 20 receives the information including the brand name from the seller to generate a payment window (S200).

In order to generate the payment windows 72 and 73, a representative embodiment of the 'input window 60 for generating a payment window' provided to the seller in the secure transaction site 20 is illustrated in FIG. 3. There is a crucial difference from the 'input window for generating a payment window' presented in the invention by the same applicant (Application No. 10-2007-0111702) as follows.

In the method for providing an escrow payment method according to the present invention, since the buyer directly inputs the product amount through the 'transaction amount input window 71' which will be described later, the 'input window 60 for generating a payment window' indicates that the seller has There is no entry for entering a price.

Looking at the input for generating the payment window with reference to Figure 3 as follows.

The transaction information is a field for briefly inputting transaction information to distinguish generated payment windows, and the quantity is a field for inputting the quantity of goods to be sold. The quantity is displayed as 'sales proceed quantity / sellable quantity', and when all the sellable quantities are completed, the payment window button 70 is not activated in all web environments 30 in which the payment window button 70 is exposed. Do not. In the DB of the secure transaction site 20, fields for sales proceed and sales available are provided, and the number of sales available in the DB is subtracted every time the sale of the goods proceeds. When the payment window button 70 is activated, it is checked whether the sellable quantity field of the safe transaction site 20 has reached '0' and when the payment window button 70 has reached '0', the payment window button 70 is deactivated.

The transaction page is a field for registering a sale product and inputting a URL of an internet page in sale, and the memo column is a field for recording other necessary information.

The transaction approval code is a field for inputting information consisting of numbers, letters, or a combination thereof for authenticating the transaction approval between the seller and the buyer arbitrarily inputted by the seller. Only to protect the stability of the transaction by notifying the buyer to the buyer. The transaction approval code may be arbitrarily entered by the seller, or alternatively, the secure transaction site 20 may be arbitrarily assigned and the seller may remember it.

The transaction approval code is a trading device designed to prevent unavoidable events that may occur in a special exchange environment, which is a transaction between an individual and an individual, not a company and an individual. Looking at the transactions between individuals, they have the following characteristics.

The quantity of goods sold is very limited, and used goods are being traded more actively than new products. Therefore, by providing a transaction approval code input process through the communication between the seller and the buyer, it is possible to prevent the other buyer to pay again for the sale is completed.

In addition, the transaction approval code can be particularly useful for the transaction of used goods. Unlike used goods, used goods can be finalized only after agreeing the intention between the seller and the buyer. For example, if the seller wants to sell a used bicycle, the buyer's nature of the used goods allows the buyer to listen in detail to the condition of the product and the terms of the dividends, and then the deal is made after the seller and the buyer promise to buy and sell each other. Is common. By providing such a transaction approval code, it is possible to prevent a large number of cases where a buyer requests a refund after purchasing a product without consulting with the seller.

If the item needs to be delivered, it will choose information about whether the seller or the buyer will pay for the shipping. If other shipping costs are unnecessary, it is of course possible to add a field for selecting a transaction (direct transaction).

The secure transaction site 20 registers the contents of the 'input window 60 for generating the payment window button' input by the seller in a database, and inputs for generating the 'payment window button' registered by the seller so that the seller can check. Provides a list of windows 60 '.

When the registration and storage of the sale item information through the input window 60 for generating the payment window button is completed, the payment window button 70 for the item registered by the seller is generated. The type of 'payment window button 70' may be selected as a text form or an image form. This is to be prepared according to the seller's preference and to prepare for the web environment 30 in which an image is not provided. Image form is provided in the form of the image basically provided by the secure transaction site (20), if you press the 'Edit' button of the 'Payment window button 70' selection so that the text included in the image of the payment window button 70 can be changed It was.

When the 'copy' button is pressed, the 'payment window button' generated in the text or image form can be copied to the clipboard of the seller device 40.

(3) The seller registers the product information to be sold in the web environment 30. (S300) Registers a picture, a characteristic, and the like of the product to be sold, and especially if it is a used product, whether it is used, directly received, or delivered to the door. Enter such information. In the case of camera parts, the camera parts to be sold on the 'membership transactions' site of the camera club site are registered together with the corresponding product information.

(4) The seller registers the product information to be sold and exposes it by pasting the 'payment window button 70' copied to the clipboard to a part of the page. (S400)

4 illustrates an example of a screen in which a 'payment window button' is exposed on a web page. As shown in FIG. 4, a 'payment window button 70' in a text form or an image form is generated in a predetermined region of a web page in which information on an item to be sold is described.

In the site where the image DB link button can be used, the image form 'Payment window button 70' including the name entered directly by the seller can be used. In the site where only the text DB link can be used, the user can enter the text form directly. 'Payment window button' is provided.

(5) The buyer confirms that the desired item is posted while searching the desired web environment 30 through the web.

(6) After reviewing the information of the posted goods, the purchaser provides the memo function provided by the seller's mobile phone, email or web environment 30 for bargaining and other inquiries about the desired selling price of the goods presented by the seller. (S500)

(7) The final agreed price of the goods is derived by bargaining through the above process, and the buyer clicks on the 'payment window button 70' to finally purchase and pay the goods according to the derived price. )

(8) The buyer who clicks the 'payment window button 70' is required to input the 'transaction approval code', and the seller enters the transaction approval code notified by the buyer.

The transaction approval code may be automatically generated systematically in the secure transaction site 20 or may be generated by the seller directly inputting. In addition, the transaction approval code notifies the buyer when the transaction is finally confirmed through the negotiation process between the seller and the buyer.

(9) When the buyer enters the transaction approval code, the secure transaction site 20 receives the 'transaction approval code', authenticates it, and if the transaction approval code matches, the payment window (72,73) for actual payment of the product. ) Is provided to the buyer in the form of a pop-up or page depending on the service environment.

5 is a final consultation price and purchase decision is made through the consultation process with the seller, and when the buyer who is notified of the 'transaction approval code' from the seller clicks the 'payment window button', it is provided in a pop-up form or a page form. One embodiment shows a payment window.

In the settlement window of the method for providing an escrow payment method according to the present invention, unlike the invention by the same applicant as the present invention (application number: 10-2007-0111702), 'the transaction amount' is not presented. Instead, by providing the 'transaction amount input window 71' is configured so that the buyer can directly enter the final transaction amount determined through the consultation process of step S500 into the 'transaction amount input window 71'.

Referring to FIG. 5, when the buyer clicks the 'payment window button 70' and inputs a 'transaction approval code' granted from the seller, the safe transaction site 20 presents a 'member / non-member confirmation window'. When the purchaser clicks on the member button, the purchaser enters the purchaser's secure transaction site 20 member ID and password to authenticate the membership.

After membership verification, the secure transaction site 20 presents the 'payment window' shown in the right side of FIG. The 'payment window' presents buyer ID, contact information, shipping address, and bank information with reference to buyer information stored in the member DB of the secure transaction site 20.

In the case of a non-member, as shown in FIG. 6, a [non-member purchaser safety transaction site] window is presented, which requires real name authentication and inputs bank information to be refunded.

(10) When the seller clicks on the member button of the safe transaction site 20, the contents of the payment window 72 shown in FIG. In order to change the information by clicking the modify button.

When the seller clicks the non-member button of the secure transaction site 20, the payment window 73 of FIG. 6 provided by the secure transaction site 20 is activated, and the buyer (non-member) enters the real name authentication and the shipping address and the transaction bank information. Will be done.

(11) After the purchaser confirms or inputs the buyer information through step S800, the buyer directly inputs the final transaction amount determined through the consultation process of step S500 directly into the 'transaction amount input window 71' (S900).

That is, the system and method for providing an escrow payment means using the transaction amount input window 71 according to the present invention is different from the method in which the buyer pays according to the amount presented, since a payment amount fixed in the payment window is presented as in the related art. In this case, the purchaser directly enters the transaction amount and proceeds with the payment.

Therefore, after the seller decides the sales amount, the seller and the buyer negotiate through the mobile phone, etc., and if the sales amount changes, the seller does not need to access the safe transaction site again and modify the sales amount accordingly. This enables buyers to make payments faster and to provide a more convenient trading environment for both sellers and buyers.

(12) The buyer pays the deposit as much as the transaction amount input in step S900. (S1000) At this time, the secure transaction site presents various payment modules in connection with a financial institution / card company and pays the deposit through the means selected by the buyer. do.

(13) The purchaser clicks the 'make a payment (74,75)' button shown in the 'payment window (72, 73)' of Fig. 5 or 6 and proceeds with the payment. At this time, the secure transaction site 20 provides buyers with a variety of payment methods such as card payment, bank deposit, and checks whether a deposit has been deposited through the financial sector. The payment confirmation will be sent to buyers and sellers via email, text message, and message.

(14) The secure transaction site 20 confirms the deposit and requests the seller to deliver the item. (S1100)

(15) The seller checks whether the amount of the deposit is consistent with the final price determined through consultation with the buyer, and if the amount is identical, the seller proceeds to deliver the item (S1200), and the 'payment window' presented in the web environment 30 is provided. Button 70 'is changed to indicate the current delivery status as shown in FIG. In FIG. 7, although several buttons are displayed as being continuously shown, this is for convenience of description and in actual implementation, indicates a delivery progress state through one 'payment window button 70'.

Therefore, the purchaser who has completed the payment can easily receive the information about it by clicking the payment window button 70 on the web page where the item was purchased, without having to access the web page of the separate transaction relay site. . The information is provided in real time in connection with the secure transaction site DB.

This ensures that the secure transaction site 20 has a field for 'string displayed on the payment window button 70', and when the status field is received from the shipping company, the status is set to 'string displayed on the payment window button 70'. To reflect that.

If it is assumed that the 'string displayed on the payment window button 70' is 'XXX' after the initial payment, the string to be entered in the 'string displayed on the payment window button 70' is 'YYY' when the delivery is in progress. Assume When the payment is confirmed and the signal indicating that the seller is delivering from the courier as the shipment proceeds to the safe transaction site 20, the string displayed on the 'payment window button 70 in the DB of the safe transaction site 20 When the buyer clicks the payment window button 70 by converting the string of 'XXX' to 'YYY', it indicates that the payment is being made by referring to the DB when the payment window button 70 is activated. In addition, by entering a transaction approval code delivered to the seller at the click of a button, only the buyer can check the progress.

(16) After the buyer receives the goods, if there is no problem with the purchased goods, the buyer notifies the purchase transaction to the safe transaction site 20. (S1300)

(17) The secure transaction site 20 having received the purchase confirmation signal requests the banking device 10 to deposit a deposit into the seller account.

(18) After the safe transaction site 20 limits the transaction fee, the remaining goods sales price is paid to the seller. (S1400)
