On-line transaction method for exchanging second-hand articles

The invention relates to an on-line transaction method for exchanging second-hand articles, wherein a client platform is connected to a website platform through the Internet. When logging in a member management system, a member can use an article searching match system to find whether there is required article in a member article cabinet. It is regarded as a successful match if the article is released by a member. A member interaction system may pre-deduct exchanging points in the account of request-side member. A match management system informs the logistics operator of obtaining the article from the exchange-side member and then deliveries the article to the request-side member, while the required expense is paid by the request-side member. The logistics operator or the exchange-side member may inquire the delivery state by entering track serial number into a logistics management system so that the member interaction system adds the pre-deducted exchanging points into the account of the exchange-side member
