With the continuous improvement of the living standard of people and the continuous abundance of commodities in the consumption market, people have more and more choices for purchasing material commodities. Meanwhile, people participate in the market link of commodities more and more, and not only the commodity purchasing requirement but also the commodity selling desire and requirement exist. Therefore, many channels are available in the market for people to sell or exchange their own physical goods. For example, people may sell products by displaying pictures of the products through the online C2C application platform, by selling products through product display grids in a physical store, or by selling products through platforms such as online blogs and wechat. All these customers belonging to non-professional merchants have some common traits or challenges for the customers, namely the selling or purchasing of the commodity of the type C2C, including the display of the commodity, with the limitation that the pictures displayed on line often do not completely correspond to the physical commodities; the authority of the transaction contract between the online sale and the purchaser; security of the transaction payment link; and third party charges for the online platform or the offline sales-replacement platform; and so on. All of these constitute C2C, the challenge and risk of direct commodity transactions between customers by customers.
However, with the development of modern technologies, such as the increasing popularization of smart phones and the increasing wide application in finance, the secure man-machine communication platform NFC technology based on smart phones, especially the continuous improvement of the block chain technology in recent years, people can technically establish reliable point-to-point, that is, a smart contract from a client to a client, and can establish irreversible and non-falsifiable transaction records without depending on a third-party authority. All the function guarantees on the technical level provide a reliable, safe and convenient commercial environment for guaranteeing the direct commodity transaction of the client to the client in commerce.
The invention provides a platform system and a method for directly selling commodities in a C2C form by a client on the basis of a block chain technology platform by combining the NFC communication function of a smart phone and an unmanned commodity display cabinet capable of being dynamically and rapidly deployed.
