Description

Sequential exchange method of item matching

The invention relates to an exchange method, in particular to a sequential exchange method for matching items.

In recent years, the Internet has become very common. With the vigorous development of the Internet, it has driven the development of auction platforms and shopping websites, and also brought huge shopping opportunities. The current operation methods of online shopping can be roughly divided into two categories, namely electronic stores and electronic malls.

The former refers to a single seller, such as a specific brand and a single gang; the latter is mostly presented in the form of a common shopping mall, mainly selling a variety of brands and products, such as Qimo Shopping Center. But in either case, it is a process of ordering, interacting, and transacting through the Internet, and then distributing the goods through the logistics system.

However, compared with traditional shopping, because traditional shopping must have physical stores and manpower deployment, there are more costs and expenses. Compared with online shopping, these costs can be saved. Moreover, buyers can also purchase items directly on the shopping site without leaving the home. Therefore, this emerging type of transaction has gradually evolved into one of the most popular origins of "e-commerce". Moreover, once the Internet becomes more and more popular, as long as they can master and use the Internet, everyone can start a business, and everyone can buy goods through the Internet.

However, with the gradual rise of environmental protection consciousness, the bartering transaction model has risen again, coupled with bartering to save the "golden flow" in e-commerce. Therefore, in the current depressed environment, this kind of money-saving and environmentally friendly barter transaction is even more fueled.

The so-called bartering or bartering, as the name implies, refers to the use of what you already have to exchange with others in exchange for other people's goods. Long before humans used money for trading, humans knew how to barter. Bartering is different from buying and selling, and does not use any money for trading tools, so bartering is not necessarily an equivalent exchange.

However, in today's society, bartering is a kind of sales behavior. The parties to bartering are not settled in currency, but settle each other's goods with the same price to realize the sale of goods.

And this method is quietly becoming a new way for the global people to resist economic difficulties. In a broader definition, each person, organization, or community can exchange the resources they have in exchange for resources they do not have. The idea of bartering things is to create value for these items, to give them values that are not used in personal homes, and to obtain other items through exchanges, thereby saving expenses.

Therefore, many bartering websites have sprung up like mushrooms, such as websites such as Barter Exchange, Craigslist, and Tradeduck.com. There are also trading platforms for mobile apps, such as Swapub and other apps.

However, in the bartering website, in addition to the huge amount of item information that users will face, after finding the desired item, they must also be in a situation where both parties are interested in the items provided by each other, meaning a double Demands are coupled so that the two sides can exchange successfully. But the chance of achieving double coupling is very small, resulting in users having to spend a lot of time and energy, and even reduce their willingness to use the barter website.

Therefore, today's barter platform provides a multiplayer pairing mode. After matching the needs of everyone's items, everyone is notified and exchanged together. However, this exchange model will make everyone aware of the identity of others on the barter platform. Therefore, everyone in the multiplayer mode will no longer maintain privacy.

For this reason, how to enable everyone to successfully perform multi-person pairing on the barter trading platform, and to allow the transaction users who perform the multi-person pairing to maintain their own privacy, is a problem that needs to be solved by the technical personnel at this stage.

The main object of the present invention is to provide a sequential exchange method of item matching. By using the sequential exchange method, a multi-person pairing item mode can be performed, and the privacy of the client in this mode can be protected.

In order to achieve the above-mentioned object and effect, the present invention discloses a sequential exchange method for item matching, in which a server matches the exchange information and demand information uploaded by each client. When the match is successful, the server will generate an exchange sequence and send an exchange message to each client, and one of the clients will exchange with the other clients in sequence according to the exchange sequence list on the exchange message.

The present invention provides an embodiment, the content of which is a sequential exchange method for item matching, wherein the exchange sequence further includes an exchange sequence table.

The present invention provides an embodiment, the content of which is a sequential exchange method of item matching, wherein the step of matching the server according to the first information further includes the step of: the first exchange information and the second demand When one of the information matches and the second exchange information matches one of the first demand information; the server sends the exchange messages to the first client and the second client; and the first client is based on The exchange messages exchange the first item of the first information and the second item of the second information of the second client.

An embodiment of the present invention provides a sequential exchange method for item matching, wherein the exchange messages further include a plurality of exchange location information and a plurality of exchange item information.

The present invention provides an embodiment, the content of which is a sequential exchange method of item matching, wherein the exchange messages are completed on the first client, the second client after the corresponding exchanges are completed. The UE and one of the third UEs are removed from the electronic device.

The present invention provides an embodiment, the content of which is a sequential exchange method of item matching, wherein when the exchange messages corresponding to the exchanges are not completed, the exchange messages are sent to the first one after a period of time. One of the client, the second client, and the third client is removed from the electronic device.

In order to make the reviewing committee members have a better understanding and understanding of the features of the present invention and the effects achieved, I would like to provide examples and cooperative descriptions, as described below:

In view of the fact that in the multiplayer pairing mode, the user terminal will no longer maintain the influence of privacy, and accordingly, the present invention proposes a sequential exchange method of item matching to solve the problems caused by the conventional technology.

In the following, the features included in the sequential exchange method of the item matching of the present invention, the matched structure, and the method thereof will be further explained:

Please refer to FIG. 1 and FIG. 2, which are a flowchart of an embodiment of the present invention and a schematic diagram of an embodiment of the present invention, respectively. As shown in the figure, a sequential exchange method for item matching in the present invention includes the following steps:

S1: The first client, the second client, and the third client upload the first information, the second information, and the third information to the server, respectively. The first information includes the first exchange information, the first demand information, and the second information. Contains the second exchange information and the second demand information and the third information includes the third exchange information and the third demand information;

S3: The server matches according to the first information. When the first exchange information matches the second demand information and the second exchange information does not match the first demand information or when the first exchange information and the second exchange information match. When they match and the second demand information does not match the first exchange information;

S5: The server reads the third information, when the second exchange information matches the third demand information and the first demand information matches the third exchange information or when the first exchange information matches the third demand information and the first When the second demand information matches the third exchange information;

S7: The server generates an exchange sequence and sends exchange messages to the first client, the second client, and the third client according to the exchange sequence.

S9: The first client and the second client receive the exchanged messages respectively;

S11: The first client exchanges the first item of the first information and the second item of the second information of the second client according to the exchange message;

S13: the first client and the third client receive the exchanged messages respectively; and

S15: The first client exchanges the second item with the third item of the third information of the third item according to the exchange message.

As shown in step S1, a first client 1, a second client 2, and a third client 3 use an electronic device to upload a first information, a second information, and a third information to a server, respectively. 4, wherein the first information includes a first exchange information 11 and a first demand information 12, the second information includes a second exchange information 21 and a second demand information 22, and the third information includes a third exchange Information 31 and a third demand information 32. The electronic device is a smart phone, a personal digital assistant (PDA), a notebook computer, a desktop computer, or a tablet computer.

Continuing the above, the server 4 in step S3 performs matching according to the first information, and further includes steps:

S31: when the first exchange information matches the second demand information and the second exchange information matches the first demand information;

S33: the server sends an exchange message to the first client and the second client; and

S35: The first client exchanges the first item of the first information and the second item of the second information of the second client according to the exchange message.

Please refer to FIG. 3, which is a flowchart of another embodiment of the present invention. As shown in the figure, in step S31, when the first exchange information 11 matches one of the second demand information 22 and the second exchange information 21 matches one of the first demand information 12, the server 4 is Stop reading any information, and then proceed to step S33 to send the exchange messages 40 to the first client 1 and the second client 2, and the first client 1 uses the first information according to the exchange messages 40. A first item 13 is exchanged with a second item 23 of the second information of the second client 2.

Furthermore, as shown in step S3, the server 4 matches the first information and reads the second information. When the first exchange information 11 matches one of the second demand information 22 and the first When the second exchange information 21 does not match one of the first exchange information 12 or when the first exchange information 12 matches one of the second exchange information 21 and the second exchange information 22 and one of the first exchange information 11 If they do not match, step S5 is continued.

As shown in step S5, the server 4 reads the third information, when the second exchange information 21 matches one of the third demand information 32 and the first demand information 12 and one of the third exchange information 31 When they match or when the first exchange information 11 matches one of the third demand information 32 and the second demand information 22 matches one of the third exchange information 31, the server 4 stops matching and continues Step S7.

As shown in step S7, the server 4 generates an exchange sequence, and transmits a plurality of exchange messages 40 to the first client 1, the second client 2, and the third client 3 respectively according to the exchange sequence. Please also refer to Figure 4, which are schematic diagrams of the transaction sequence table of the present invention, respectively.

As shown in steps S9 to S15, first the first client 1 and the second client 2 respectively receive the exchange messages 40, and the exchange messages 40 of the first client 1 further include an exchange Sequence Listing 41. Furthermore, the first client 1 uses the first information 13 of the first information and the second information of the second information of the second information according to the exchange sequence list 41 of the exchange messages 40. 23 for exchange. After the exchange is completed, the server 4 sends the exchange messages 40 to the first client 1 and the third client 3, and the first client 1 according to the exchange sequence of the exchange messages 40. In the list 41, the second item 23 is exchanged with the third item 33, which is one of the third information of the third client 3.

Continuing the above, and please refer to FIG. 5, which is a schematic diagram of the message exchange of the present invention. As shown in the figure, the exchange messages 40 further include a plurality of exchange place messages 401 and a plurality of exchange item messages 402.

And after the exchange messages 40 are completed in the corresponding plurality of exchanges, the exchange messages 40 are moved in an electronic device of the first client 1, the second client 2, and the third client 3. except. Or when the exchanges corresponding to the exchange messages 40 are not completed, then the exchange messages 40 are in the first client 1, the second client 2 and the third client after a time. Remove one of the 3 electronic devices.

By controlling the time that the exchange messages 40 stay on the electronic device of the first client 1, the second client 2, and the third client 3, the first client 1, the first The privacy of the second client 2 and the third client 3.

The following is an application description of a sequential exchange method for item matching in the present invention, and please refer to FIGS. 6A-6B, which is a schematic diagram of an application of an embodiment of the present invention:
