Description

Method and apparatus for a network system designed to facilitate the commerce of barter style in which withdrawal of remainder is free in the limit of the amount of payment}

The present invention relates to a method and system for internet commerce that balances the purchase amount and the sale amount of each member to a plurality of members and consequently promotes a barter method.

Internet commerce is a method of selling goods using the Internet. Internet sales methods, which are widely used at present, can be classified into general sales and auctions. General selling is a sales method in which a seller builds a website containing a catalog of products sold by himself or in conjunction with several sellers, and allows a buyer to order and pay a product using a computer.

Auctions include general and reverse auctions, a method of sale in which a broker builds a website and makes pricing decisions between the seller and the buyer.

This method of internet sales has the advantage of convenient shopping and access to a lot of information, but it takes a lot of time for buyers to make payments for each transaction, especially when it comes to credit card payments. In addition, there is a disadvantage in that the seller pays for the credit card to be certified by the certification authority. In addition to the settlement problem, the current Internet sales are the one-sided relationship between the seller and the buyer. In the case of a physical store, there is a regular customer. In particular, if the customer is in the sales business, the seller may be a customer of the regular customer, but this is almost impossible in the internet sale. Due to such one-sided transactions, it is difficult to secure regular customers through internet sales methods, and in order to retain customers, many promotional events, including events and discounts, must be carried out.

In order to solve the problem of settlement and one-sided transaction relationship of Internet commerce, payment is not necessary in principle, and it is preferable to use the Internet sales method in the form of bartering, as the transaction is performed on equal terms.

However, the current barter trading is mainly in the level of replacing used goods owned by other individuals owned by other individuals, so that the transaction is difficult to be made and there is no means to promote the transaction, so it is difficult to expand greatly.

An object of the present invention is to solve the problems caused by the one-sided transaction relationship and payment problems of the current Internet sales method, the Internet to facilitate the barter (barter) method for a large number of members It is to provide a trading method and system.

Barter, or barter, is a trading method in which all transactions are made without cash because the sales and purchases are the same. However, this is only possible in a barter transaction of 1: 1 type and is practically impossible in multilateral transaction. This is because the transaction must occur at the same time in order for the transaction to take place without cash, and the sales and purchase amount of each member must be the same, because this is not practical.

As a way to resolve such time discrepancies and amount discrepancies, there is a method of allowing each member to trade on credit, but it is not preferable in view of the damage caused by the traumatic transaction, and there is no guarantee that the sales amount and purchase amount can be matched. In order to carry out a multi-barter transaction without a credit transaction, some cash deposits or withdrawals are inevitable.

The present invention is a method for facilitating a multi-party barter trading method, which induces an equal amount of money deposited and withdrawn by each member, but results in a balance between a sales amount and a purchase amount. It provides a sales method and apparatus of the method.

In order to achieve the above object, the present invention creates an account for each member in a database of a computer system, and when a transaction occurs, payment is made through the transfer of the balance on the account without actual cash movement. If there is a shortage, additional deposits will be made and if there is a balance in the account, the balance will be freed within the deposit amount, thereby providing a method and system for facilitating the trading of the barter method.

In order for barter trading to take place, the purchase amount and the sale amount must coincide, which means that the withdrawal amount and the deposit amount coincide. For example, in a closed market that is operated only as a member, if a member named A buys 100 won, buys a product, and receives 100 won, and sells the product, the purchase amount and the sale amount are equal to 100 won, The amount of money invested and the amount of withdrawal, that is, the money sold in the member market after the sale of the goods are the same. If a member deposits 100 won in the member market and withdraws 200 won, it means that the sales amount is 100 won more than the purchase amount, which is against the barter method. To prevent this, it is necessary to induce the withdrawal within the limit of the deposit amount and to induce the purchase amount and the sales amount to be equal by penalty for the amount exceeding the deposit amount. If deposits and withdrawals are made from time to time, it is necessary to allow the withdrawal to be made freely within the total amount of the deposits minus the total withdrawal, that is, within the limits of withdrawal and withdrawal, and to regulate the amount exceeding the withdrawal amount. It would be effective to prohibit the withdrawal of the excess amount and to increase the purchase of goods to offset the excess amount or to impose a certain penalty on withdrawal. Forcing sales to reduce sales because they exceed purchases is undesirable because there is a risk of stagnation in the market.

On the other hand, if the deposit amount exceeds the withdrawal amount, the sales are sluggish or the purchase amount is high, which can be regarded as contributing to the member market. In this case, forcing the purchase amount to be reduced may cause contraction of the member market, which is not preferable. Therefore, it should be induced to activate sales.

In order to achieve a balance between the deposit amount and the withdrawal amount as described above, the present invention provides an order input step 31 in which a member wants to purchase an order; A balance history output step (32) for retrieving and notifying the balance by searching the member accounts of the members who ordered the goods; A payment application input and processing step 33 in which the member inputs the payment data and processes the payment data; Order member account update step 34 of updating the account of the member who ordered the product; An order history output step 35 informing the member who has sold the order data of the order data; A sales member account update step 36 of updating the sales member's account; A withdrawal request input step 37 in which the member inputs withdrawal request data; It provides a method and apparatus for facilitating a barter transaction free of balance within the deposit amount range, characterized in that it comprises a withdrawal member account renewal step (38) for updating the account of the member according to the withdrawal.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the order input step 31, a member who wants to make a purchase accesses the server 11 using the member computer 27, opens a web page 13, and searches for product data on the product database 18 to make a purchase. After selecting the product is made by inputting the purchase order data, including the purchase application product code, product name, price, quantity, sales member code, purchase member code, purchase member password to the server (11).

In the case of a member who wishes to trade by auction or reverse auction, he / she uses the member computer to access the bulletin board of the web page 13 and publish the posting data including the brand name, the trade terms and the e-mail address of the publisher. ), The server 11 generates a serial number for the posted data and records it in the bulletin board database 25 together with the posted data, and a member who wishes to respond to the transaction uses a member computer to After the e-mail address is sent and the e-mail is sent and the two members then send and receive e-mails, the opinions are adjusted between the members, and the sales member registers the product with the server 11 using the member computer 28, The server 11 registers the product data including the product name, product code, price, and seller code of the product in the product database 18, and the purchase member Seller's code, the code is made by the purchaser, purchasing brand name, purchase amount, and enter the password auction and reverse auction purchasing membership scheme of the order entry stage 31 by the product ordered.

In the order input step 31, the member code and password together with the data about the product should be input from the member computer 27 to the server 11, but if the member has not yet registered, membership can be registered at this step.

Membership application form is output from the server 11 to the member computer 27, the membership application data, including the member name, member password, address, phone number, email address from the member computer 27 server (11) In the server 11, the processor 12 generates a member code and a membership date and time together with the program 14 and records it in the member database 16 together with the membership application data and newly joins the member. In order to record the transaction details and deposit and withdrawal of a member, create a member account database consisting of member account data including membership code, transaction date and time, purchase amount, sales amount, deposit amount, withdrawal amount, balance, and withdrawal amount. The completion message is made by outputting from the server 11 to the member computer 27.

In the balance history output step 32, when an order member code and a password are input, the processor 12 of the server 11 interoperates with the program 14 to search for the corresponding member code on the member database 16 and confirm the password. If it matches with the data entered afterwards, check the balance of the member in the member account database (17), and the small amount of the order amount and the balance is the balance payment amount, and the additional amount is the amount after subtracting the balance payment amount from the order amount. In order to select a method of depositing the additional deposit amount from among credit card, electronic money, online deposit, and credit deposit, the server 11 forms a data and payment method including a balance, order amount, balance payment amount, and additional deposit amount. The step of outputting from the member computer 27 to.

The payment data input and processing step 33 will be described with reference to FIG. The member checks the balance payment amount and the additional deposit amount output in the balance history output step 32, corrects as necessary, selects a payment method, and the balance payment amount, the additional deposit amount, and the payment method from the member computer 27 to the server 11; Payment amount and method input step 41; Checking whether the sum of the balance payment amount and the additional deposit amount is identical with the purchase amount at the server 11 and outputting a payment amount re-information guide message to the member computer 27 if it does not match; When credit card payment is entered as a payment method, credit card payment information including credit card type, credit card number, expiration date, owner name, and payment amount is input from the member computer 27 to the server 11 Input step 44; A payment authentication request step 45 of outputting credit card payment information including a credit card type, a credit card number, an expiration date, an owner name, a payment amount, and a merchant code from the server 11 to the authentication computer; A payment authentication input step 46 in which a payment approval number is input from the authentication computer to the server 11; The server 11 records payment data including an order number, a payment number, a credit card number, an authentication number, and a payment amount in the payment database 21, and an order number, an order date and time, and a buyer in the transaction result database 20. And a database recording step 5 for recording transaction result data including a code, a seller code, a product code, a product name, a unit price, a quantity, an amount, and an amount for each payment method.

If online payment or other payment method is entered as the payment method, the order number, order date and time, buyer code, seller code, product code, unit price, quantity, amount, balance payment amount, addition are added to the order database 19 on the server 11 An order database recording step 47 for recording the order data including the deposit amount and the additional deposit method, and outputting the payment price online payment destination guide message from the server 11 to the member computer 27 together with a message indicating that the order has been received; After the online deposit amount is actually deposited from the member, the deposit date including the deposit date, the deposit amount, the name of the depositor, and the order number is inputted to the server 11 to input the deposit date, the deposit amount, the name of the depositor, the order number to the deposit database 22. A deposit information input step 48 of recording deposit data including; A deposit database recording step 49 for reading data corresponding to the order number on the order database 19 and recording it in the transaction result database 20; To the database recording step 50 for recording the transaction result data including the order number, order date, buyer code, seller code, product code, product name, unit price, quantity, amount, amount by payment method in the transaction result database 20 It is composed.

The order member account update step 34 includes items such as purchase date, order number, transaction product name, vendor code, purchase amount, sale amount, deposit amount, withdrawal amount, balance, and withdrawal difference according to the order. It is recorded in the member account. The purchase amount of the item becomes the order amount, the sales amount becomes 0, the deposit amount becomes the additional deposit amount, the withdrawal amount becomes 0, and the balance is the amount processed as the balance payment from the existing balance in the member account database 20 Minus the new balance.

The withdrawal difference is the sum of the deposit amount minus the sum of the withdrawal amount, which is to check whether the sum of the amount withdrawn by the member exceeds the amount of the deposit amount and the limit to withdraw further until the deposit amount and withdrawal amount are the same. Becomes The amount of deposit and withdrawal is calculated by Equation 1.

Withdrawal difference = Existing withdrawal difference + Additional deposit amount-Withdrawal amount

Therefore, the purchase and withdrawal difference of the purchase member is an amount of the additional withdrawal amount plus the existing withdrawal and withdrawal difference. Each item calculated as above is recorded in the member account database 17.

The order history output step 35 is a step of outputting order-related data including the order product name, unit price, quantity, amount, order name, delivery place, and recipient according to the order to the sales member computer 28. The data output to the sales member computer 28 is transmitted to the e-mail address of the sales member by a mail server program, which is one of the programs of the server 11, and the sales member computer 28 It can be viewed by the E-Mail program of the seller, the seller can also access the server 11 to query the transaction result database 20 can be confirmed.

The sales member account renewal step 36 includes items such as transaction date, order number, transaction product name, purchaser code, purchase amount, sales amount, deposit amount, withdrawal amount, balance, and withdrawal difference, etc. in the sale corresponding to the order. It is recorded in the corresponding member account of the management database 17. Among the items, the purchase amount is 0, the sales amount is the sales amount of the corresponding vendor, the deposit amount is 0, the withdrawal amount is 0, and the balance is the new balance added from the existing balance in the member account database 17. Becomes The difference between the withdrawal and withdrawal of the sales member is also obtained by the above Equation 1, and the withdrawal and withdrawal amount of the sales member is equal to the existing withdrawal and withdrawal amount since the deposit amount and withdrawal amount are each 0. Each item calculated as described above is recorded in the corresponding member account on the member account database 17.

In the case of incurring a commission due to sales, the transaction product name of the sales member account becomes a sales commission, the sales amount, purchase amount, and deposit amount becomes 0, the withdrawal amount becomes a sales commission, and the balance is the sales commission from the existing balance of the member account. The amount is minus the amount, and the deposit and withdrawal difference is the amount by subtracting the sales commission from the existing deposit and withdrawal difference by the equation (1).

On the other hand, a linked member code, that is, a company or a group code, may be operated for a case where a company conducts a transaction for each department but finally manages transaction details in a company unit. The linked member code is inputted from the user computer 27 to the server 11 at the time of membership application and recorded in the member database 16. When the member makes a transaction, the server 11 records the same data as the data recorded in the member's account in the linked member's account.

The withdrawal application input step 37 is a withdrawal application including a withdrawal application member code, member password, withdrawal application amount, bank name, bank account number, withdrawal request date and time after the member computer 27 is connected to the server 11; Data is inputted from the member computer 28 to the server 11. If the withdrawal request amount is greater than the balance on the member account or the deposit and withdrawal difference, the withdrawal request amount re-entry message is sent from the server 11 to the withdrawal request member computer 28 to be input again.

The withdrawal member account renewal step 38 is a step of updating the member account according to the withdrawal in the server 11, the transaction details on the member account is withdrawn, the sales amount, the purchase amount, the deposit amount becomes 0, and the withdrawal amount is the withdrawal application amount. The balance becomes the amount after subtracting the withdrawal amount from the existing balance, and the withdrawal difference is the amount after subtracting the withdrawal amount. Each item calculated as described above is input to the corresponding member account on the member account database 17.

When the withdrawal application amount exceeds the withdrawal difference, the withdrawal may be made within the withdrawal difference, thereby facilitating the purchase of goods. There is also a method to withdraw the withdrawal fee for the amount exceeding the withdrawal difference of the withdrawal application amount. In this case, for example, assuming that the withdrawal fee is 5% rate, the withdrawal fee is calculated by Equation 2.

Withdrawal fee = (withdrawal amount-withdrawal amount) × 5%

When a withdrawal fee occurs, the withdrawal fee on the member account database 17 of the member becomes a withdrawal fee, and the balance becomes an amount minus the withdrawal fee from the existing balance, and the withdrawal and withdrawal difference becomes zero. The reason that the withdrawal difference becomes zero instead of the difference between the withdrawal amount and the withdrawal amount according to Equation 1 means that the withdrawal request amount is larger than the withdrawal difference with the withdrawal fee. The withdrawal fee is the penalty for this negative amount and the penalty is resolved by paying the penalty.

Unlike a withdrawal limit of-, giving a penalty, if the withdrawal difference is positive, a certain amount of incentive may be added to all or part of the withdrawal difference. In this case, the server 11 reads data on each item on the member account database 20 of the member, calculates a subsidy, updates the data of each item on the member account, and records the data in the member account database 17. Is done.

For example, if the incentive amount is 5%, the incentive amount is multiplied by the difference between the deposit and withdrawal amount of 5%, the deposit amount in the member's account database 17 becomes the incentive amount, and the balance becomes the amount added with the incentive amount to the existing balance. The difference is the difference between the existing deposit and withdrawal difference minus the withdrawal and withdrawal amount plus the incentive. When the incentive is added to the total withdrawal difference, the withdrawal difference becomes zero for the same reason as for the withdrawal fee.

In this way, by joining a number of sellers as members and forming a community and trading by members, the trader can promote the balance between sales and purchases, facilitate payment, and provide sales promotion means. It is possible to provide an internet transaction method and system.

The Internet commerce method according to the present invention can solve various disadvantages due to the current unilateral commerce by forming a community with a plurality of members so that each member can trade at random by a barter method.

That is, the purchase member can pay the purchase price in paper using the balance in the account of the present invention, thereby reducing the cost incurred when making the actual payment and preventing the hassle of payment, and withdrawing the money within the range of the deposit amount. It can induce purchases and eventually promote commerce. Also, within the deposit range, the withdrawal is free and the product can be purchased at will.
