Description

E-commerce method {ELECTRONIC COMMERCE METHOD}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic commerce method, and more particularly, to an electronic commerce method that can more conveniently use a purchase and rental (lease) of goods from a user's point of view.

Recently, the e-commerce system based on the Internet is very active, and the portion of the commerce market is increasing.

These e-commerce systems have various conveniences, but most of them provide service-oriented services, and thus many inconveniences from the user's point of view.

For example, a typical type of electronic commerce system currently in place is traded as follows. First, an individual consumer (user) accesses the Internet through a computer and accesses the homepage (Internet shopping mall) on the service provider's side providing the service. The service provider's homepage is to search for and order the desired item. However, such a system has the following problems from the standpoint of the individual consumer.

First, there are a limited number of products to choose from. The individual consumer can order only the goods provided by the Internet shopping mall on the service provider side. For example, even if a manufacturer wants a product, if only the B maker's product is secured on the service provider side, or if a user wants a 34-inch TV but only a 29-inch TV is secured on the service provider's side, the consumer wants the product. You should go to another service provider.

Second, there is no device that can compare the price presented by the service provider in terms of price. In other words, even if a consumer wants to compare prices offered by various Internet shopping malls for the same product, each Internet shopping mall does not present such a comparison price, and consumers have no choice but to directly compare prices by accessing various Internet shopping mall homepages. .

Third, inconvenience when ordering. In other words, in order to order goods, consumers must sign up for membership, and when they order, they choose a credit card or a method of depositing a bankbook in cash. If the user chooses to make a passbook payment, the consumer must first deposit the price of the goods to the service provider (prepayment). If the credit card is selected as the payment method, the credit card number is entered, which also corresponds to the next payment date. Since the price of the goods automatically exits and it is not much different from the prepaid system, such as waiting for a certain period of time in order to cancel them, the consumer is quite inconvenient in canceling the transaction even if there is a defect.

Fourth, it is inconvenient in the delivery process of goods after ordering products. Currently, internet shopping malls that are currently used do not have their own logistics network, so it takes a long time for consumers to receive the actual goods, and it is unpredictable. In addition, since there is no own after-sales service network in after-sales service, A / S, it is necessary to rely on each after-sales service network of each manufacturer of the goods. This is being raised a lot.

Fifth, the complexity of the ordering procedure in using a conventional Internet shopping mall. That is, a series of procedures such as going to an internet shopping mall site, searching for an item, ordering it, confirming it, and selecting a payment method are complicated. Therefore, a user who is not good at the internet has a feeling of refusal to purchase goods using the internet, which in turn hinders the activation of electronic commerce.

These problems are attributable to the fact that they are an operator-centered merchandise trading system, which is a system that is made with the convenience of a service provider in mind rather than an electronic commerce system that is made by a consumer.

In addition, electronic commerce systems currently provided on the Internet are mostly related to the sale of goods, and no special system is provided for the rental or lease of goods.

The present invention is to solve the problems of the conventional e-commerce method as described above, to provide a user-centered e-commerce method that can be delivered to the desired item with a single input from the user (consumer, buyer, lender) position For the purpose of

In addition, the present invention, so that the transaction is made with the product provider that presents the cheapest price through the price comparison, so that the user can easily purchase the cheapest goods.

In addition, the present invention enables the user-centered electronic commerce by introducing a post-payment concept of paying for the goods after delivery to the consumer.

In addition, an object of the present invention is to provide a rental (lease) system through the user-centered Internet.

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

1 is a block diagram of the overall environment in which the present invention is used.

The buyer 1 (user) 1 and the service provider 2 are connected via the Internet. The purchaser 1 connects to the service provider 2 using a device capable of using the Internet, such as a computer and a wireless mobile communication terminal. Of course, the Internet environment is a WWW environment.

In addition, the present invention can be used in any B2C (Business to customer) or B2B (Business to Business) environment, in the case of B2B environment, the buyer (1) and the service provider (2) is a company that wants to trade a large-scale goods, etc. Will be

The service provider 2 has a web server for providing a WWW environment, etc., and has a database for storing article information provided by the article distributor 3 described later. The database, for example, is related to the price of goods, delivery time, number of possessions, etc. for each product distributor, and of course, a separate database server may be used.

Meanwhile, the service provider 2 and the goods distributor 3 will always share data 24 hours a day. The commodity distributor 3 transmits the commodity information such as the price of the commodity and the delivery time of the commodity owned to the service provider 2 whenever there is a change, and the service provider 2 immediately sends it to its own database. It will be reflected in real time.

2 is a flowchart illustrating an embodiment of an electronic commerce method according to the present invention.

First, the purchaser 1 who wants to purchase an item connects to the homepage of the service provider 2 that provides the e-commerce method service according to the present invention through the Internet.

At this time, the purchaser 1 enters the name of the desired article in a natural language in the search box provided on the homepage of the service provider 2 side. Here, the natural language refers to free input of a maker, a specification of a product, a model name, and the like, for example, "one Nongshim Shin Ramyun" and "LG Electronics White 29-inch TV L2307". Natural language search is a commonly used search technique. In this case, for example, when only part of the item information is input, if there is optional item information related to the item, the buyer may display it.

In addition, the personal information of the buyer required for the delivery of the goods is also entered. The article information thus input is stored in the server of the service provider side (S200).

On the other hand, the server of the service provider side stores the goods information such as the price, delivery time, quantity of the goods that can be distributed by the goods distributor (holding company).

Service providers and goods distributors are online 24 hours a day. The connection between the two may be any data that can be transmitted using the Internet or a wireless communication terminal. For example, it may be shared by an internet environment such as a general modem or a leased line using a telephone line. Preferably, the distributor may connect the service provider's server through the Internet to record their price changes. It is also a good idea to assign IDs and accounts, and to have write permission for those IDs and accounts.

When there is a change in the circumstances of the goods distributor, that is, a change in the price of the goods or a change in the delivery time, the goods distributor notifies the service provider and the service provider updates the database of the service provider to reflect the change. .

With this environment in place, the service provider will always have the item information for the item entered by the consumer as updated data.

Based on the product information thus provided, the service provider selects a distributor who presents the most appropriate information about the order entered by the consumer. In the embodiment of Fig. 2, the distributor who presents the lowest price is automatically selected as the seller (S300).

Next, the service provider sends a command to the selected distributor to deliver the goods, and transmits the buyer's personal information necessary for delivery (S400).

The distributor receives the buyer's personal information, delivers the goods (S500), and pays the price (S600). Of course, the service provider side directly checks the position of the seller through the consignment or sale of the distributor. You can also stand. Depending on who is the direct seller, the seller is responsible for post-delivery, after-sales service, and returns, which must be determined internally between the distributor and the service provider.

In this case, there are various methods of payment, which will be described later.

3 is a flowchart showing another embodiment of the electronic commerce method according to the present invention.

In FIG. 3, steps S100 and S200 are the same as in FIG. 2. In step S200, when the buyer inputs the desired delivery time, that is, the delivery time, while inputting the goods information on the goods, the service provider can select whether to give priority to the price or delivery time. It provides an interface so as to (S700). When the buyer selects and inputs his or her preferred criteria among price and delivery time, the buyer searches for the information of each distributor stored in the server of the service provider according to the selected criteria and selects the distributor who best meets the selected criteria as the seller. Then, the procedure similar to the procedure of FIG. 2 is performed. (S300 to S600 and S800).

4 is a flowchart illustrating still another embodiment of an electronic commerce method according to the present invention.

The embodiment of FIG. 4 is characterized in that when the buyer inputs the goods information, the buyer can select the goods by displaying the goods information held by the service provider.

If the buyer enters the item information, the information on the item is transmitted to the buyer's computer for display.In this case, the displayed information includes the current price, monthly / seasonal / yearly price, delivery time, etc. of each product manufacturer. Anything that may be deemed necessary for the buyer to purchase the goods is possible.

Next, when the buyer selects a distributor based on the displayed information, the buyer is selected as the seller and the delivery is instructed (S400). The procedure is the same as that of the embodiment of FIG. 2.

FIG. 5 is a flowchart specifically illustrating an operation S600 of paying for the goods of FIGS. 2 to 4.

In the present invention, there are various ways to pay for the goods. That is, as shown in Figure 5, there is a method of direct payment and the method of depositing online through a financial institution.

First, paying the goods directly is that the goods are delivered by the distributor when the goods are delivered and paid directly (S1100). At this time, it is of course possible to pay with cash or credit card. After payment, the distributor and service provider can settle the payment.

In addition, the method of depositing online proceeds as follows.

Once the buyer receives the goods, he writes a predetermined code on the receipt of the goods and issues it to the distributor. (S1200) The buyer pays the price of the goods together with the predetermined code described above to a financial institution such as a bank (S1300). The service provider receives the receipt of the goods, presents the password described here to the financial institution, and receives the payment for the goods (S1400).

Of course, agreements have to be made in advance between financial institutions and service providers to make this process possible.

On the other hand, in combination with the e-commerce method according to the present invention, it would be more desirable to add a procedure that provides a certain reward if, for example, a place where a buyer presents a lower price than a purchased item within a predetermined period of time.

In addition, if the goods purchased by the purchaser are not delivered within a predetermined period of time, or the designated delivery time or delivery location is missed, a procedure of compensating by incorporating a proportional discount within a predetermined period may be combined. Do.

On the other hand, the electronic commerce method according to the present invention as described above can be applied to the lease system as it is.

A lease is a type of lease, such as a lease or repurchase of goods or the return of goods by the lender after the contract period has expired.

Such a lease system can be applied to the electronic commerce method according to the present invention as it is. An example thereof will be described with reference to FIG. 6 as follows.

As shown in FIG. 6, a user 1 who wants to rent an article first accesses the homepage of the service provider 2 through the Internet (S100).

At this time, the user 1 inputs the name of the article to be leased into the search box provided on the homepage of the service provider 2 in natural language. Up to now, the same as the embodiment of the electronic commerce method described in FIG. However, there is a difference in that when inputting the product information, information about the lease period, new or used goods, etc. may be input due to the characteristics of the lease system. As in FIG. 2, the personal information of the buyer necessary for the delivery of the goods is also input and stored together with the goods information in the server of the service provider (S200).

Next, a payment settlement method is selected. (S300) This is different from the embodiment of FIG. 2 because it is characteristic of payment settlement due to the nature of the lease system. That is, although the lease system may settle payment for a lump sum (in this case, the payment method of the embodiment of FIGS. 2 to 5 may be applied as it is), most of them pay a predetermined amount on a monthly basis.

In other words, the amount of money in the user's account can be automatically transferred to the lessor, the installment can be made through credit card, the deposit can be made via Jiro paper, or a predetermined amount can be paid to the lessor through advance agreement with a financial institution. Method and the like.

Which of these methods should be chosen so that the user can select, for example, display the payment method the user can select when ordering the item and allow the user to select it.

Next, after the lease period is expired, the problem of handling the leased item is selected. (S400) This is also different from the embodiment of FIG. 2 due to the characteristics of the lease system. That is, there are various problems, such as whether to re-lease a lease article, to assign ownership to the user, whether the lease company returns the article, or re-lease it as a new article. Of course, the user may also choose the right to request repurchase.

In order to deal with this, by displaying a screen that allows the user to choose how to handle the leased goods after the lease period expires, it is possible to easily cope with the various types of leased goods processing as described above. .

Thereafter, steps S500 to S700 proceed in the same manner as step S500 in step S300 of FIG. 2. That is, referring to the goods information of the goods distributor (owner) stored in the server on the service provider side, the user automatically selects the most suitable information for the order inputted by the lender (S500), and the step ( S600) to step S700 to deliver the item to the user.

However, the payment step S800 is performed according to the method selected in step S300 of FIG. 6, unlike the payment step S600 of FIG. 2. If the user selects the lump sum payment in step S300 of FIG. 6, the payment step S600 of FIG. 2 may be applied as it is. However, if a payment method such as a partial payment is selected, the payment step (S600) of Figure 2 may be omitted, the procedure is terminated by delivering the goods, the payment is made by dividing on a predetermined day such as the end of each month You lose.

However, even when the partial payment is selected, the procedure of steps S1200 to S1400 of FIG. 5 may be applied as it is. That is, once the buyer receives the goods, writes a predetermined code on the receipt of the goods and issues it to the distributor (distributor). (S1200) The buyer pays the goods together with the predetermined code described above to a financial institution such as a bank. (S1300) The service provider receives the receipt of the goods, presents the password described here to the financial institution, and pays for the goods. (S1400) However, the payment at this time is not a lump sum but a partial payment. The monthly deposit amount will be determined by.

Meanwhile, in the embodiment of FIG. 6, the features of the embodiment of FIGS. 3 and 4 may be applied as they are. That is, as in the embodiment of FIG. 3, step S700 for selecting a price priority or a delivery time priority may also be combined, and displaying the article information as in the embodiment of FIG. 4 (S900). Steps S1000 to be selected may be combined.

In addition, in the embodiment of Figure 6, after the user inputs the item information and personal information (S200), it may further comprise the step of confirming the user's credit information. This is because it is desirable to check the credit information of the user due to the characteristics of the lease system. In this case, the credit provider may check the credit information online at the service provider server through an alliance with a financial institution or a credit checker.

In addition, in the embodiment of Fig. 6, it would be further desirable to add a procedure that provides a certain reward, for example, if the user presents a lower price than the goods leased within a predetermined period of time. In addition, in the case where the goods leased by the user are not delivered within a predetermined period of time, or when the designated delivery time or delivery location is broken, a procedure of compensating in a manner such as giving a percentage of discounts within a predetermined period may be combined. Do.

According to the present invention, if the buyer of the goods only needs to input the item information such as the name of the item to be purchased once in natural language, the goods provider selects the goods distributor who presents the lowest price from the database held by the service provider. This allows the buyer to conveniently purchase the desired item at the lowest price.

In addition, according to the present invention, since the buyer can pay the price after receiving the goods, the buyer's satisfaction can be increased as compared with the case where the payment was made in advance in the conventional Internet electronic commerce.

In addition, according to the present invention, since the distributors always share the goods information with the service provider, it is possible to promote sound price competition among the distributors and increase the efficiency of goods sales without any investment from the distributors as a whole. This leads to savings, which in turn leads to the satisfaction of the buyer (consumer).

In addition, according to the present invention, if the service provider fails to meet a predetermined condition, the compensation is provided to the service provider, so that the reliability can be ensured to the buyer, so that more efficient electronic commerce can be achieved.

In addition, according to the present invention, it is possible to compare prices from a plurality of distributors, so that from a buyer's point of view, it is possible to simply purchase the goods without having to go to various sites, and even users who are not good at the Internet can easily use them.

In addition, the effects of the present invention can be applied to the system for leasing the goods through the Internet as it is, it is possible to lease the goods more conveniently and efficiently through the Internet.
