Traveling trade system and its trade method proposing discounted price and displaying buyer's information in each transaction}

The present invention relates to a travel product trading system and a transaction method thereof. More specifically, the user can access a homepage where a travel product is traded and sell or purchase a specific travel product according to various trading methods, and display the personal information of the existing buyer at the time of purchase to support the decision of a new purchaser. When a new purchase occurs, the discounted price is applied to all buyers, and a predetermined discount rate is applied according to the purchase configured to notify the existing traders of the transaction fluctuation situation in real time. It is about.

In general, travel products are classified according to the destination and the itinerary, and the price varies depending on the price of the ticket and accommodation. Packages that include air tickets and boarding fees for a given period of time are called package tours, and most users can conveniently enjoy overseas travel at a lower price by using these package tours when planning a trip for tourism.

These tours can only be purchased separately for tickets and packaged packages that include board and board. The characteristics of airfare and lodging rates offered by lodging companies, such as airlines and hotels, have minimal foundational costs for operating aircraft and accommodations, as having empty seats and empty cabins is more damaging than providing them at low cost. As a guideline, the price fluctuates depending on the increase or decrease of the customer. As a result, many users gather during the peak season to raise prices, while in the off-peak season prices drop. According to the principle of supply and demand, the price will go up when the demand for travel products exceeds the maximum capacity, and if the supply is left because the maximum capacity is not enough, the price will be reduced by the addition of customers.

The price fluctuation characteristics of the above-mentioned travel products have a need for an integrated trading system that connects both in real time between the seller and the buyer to form an optimal price according to the change in the travel fare.

Conventional travel deals have been unilaterally responded to the price offered by airlines or travel agencies, and because some travel agencies or airlines have different rates, some buyers lose money by purchasing travel packages at higher prices. There was a case. As such, in the conventional flat travel product trading system that cannot present the price fluctuations on the basis of this, there is a problem that a certain buyer loses unilaterally.

In particular, for packaged travel products, sellers usually offer discounted prices through large deal deals with airlines and hotels, which may be lowered over time until buyers reach their maximum capacity. There is a characteristic. Another characteristic of these packaged tour packages is that each buyer has many opportunities to meet and live together on a common itinerary on the same aircraft and accommodation. In fact, by the end of the itinerary, they may develop into familiarity with each other.

Therefore, unlike conventional travel products, products that plan and sell products according to specific purposes and events are appearing nowadays, and the personal information of other buyers traveling together will be an important factor in determining whether to purchase. Can be. As such, there has been a problem in that the travel product purchase pattern of a traveler, which has recently emerged, cannot be actively accepted in sales promotion in the conventional travel product transaction method.

The travel product trading system and its trading method according to the present invention for solving the problems of the conventional travel product trading system as described above to build a trading market connecting the seller and the buyer as a homepage on the Internet, to those who wish to make each transaction To display the price of travel products according to the current number of buyers to inform the price changes, present the distribution of personal information of existing buyers to support the purchaser's decision making, and also to know the changes in transactions in real time.

The word event refers to the minimum unit of work that the processing unit 6 of the travel product transaction system 1 processes according to a user's input.

2 shows a step-by-step configuration of the joint purchase transaction method supported by the travel product transaction system 1 according to an embodiment of the present invention.

Co-purchase is one of the most popular types of purchases made by a plurality of buyers for a product sold by a single seller, and individual purchases in the real world also correspond to co-purchase on the basis of total buyers. However, the difference between the joint purchase in the present invention is that the joint purchase in daily life is completely independent and individually purchased by the buyer, so there is a difference for each purchase price, but the joint purchase in the present invention reaches the number of recruits The price is lowered from the initial price by a predetermined discount rate for each purchase, until the same price is applied to the pre-purchasers who purchased the product in advance. Thus, since no one knows the formation of the final price starting from the initial price, there is a difference from the existing e-commerce joint purchase method that establishes a purchase contract with a seller who responds to the seller at a predetermined price. .

Referring to FIG. 2, a seller wishing to sell a tour product goes through a tour product sales subscription step S10 of registering sales on the homepage 4 of the tour product transaction system 1. The seller is also applicable to the general public, including existing airlines, travel agencies. In particular, if the general public becomes a seller, it may create a new kind of job as a travel agent. In fact, the business of establishing a SOHO by opening a small shop on travel product trading on other portal sites has recently been in the spotlight. Began to receive. However, there is a vulnerability that can not guarantee the reliability of the transaction, but this can be supplemented by the policy sales management strategy of the travel product trading system (1).
