A non-transitory computer-readable medium, whose contents include a program, which, when executed on a server computer, performs a method for managing swaps of tangible and intangible items, comprising:
- registering a first user in an electronic database, receiving a first name of a first tangible or intangible item to list from a first user device through a network connection, storing the first name in the electronic database, and listing the first name on a web site using a registration module,
- registering a second user in the electronic database, receiving a second name of a second tangible or intangible item to list from a second user device through the network connection, storing the second name in the electronic database, and listing the second name on the web site using the registration module,
- registering a third user in the electronic database, receiving a third name of a third tangible or intangible item to list from a third user device through the network connection, storing the third name in the electronic database, and listing the third name on the web site using the registration module,
- receiving a first request through the network connection from the first user device for the second tangible or intangible item that begins a first transaction, removing a first credit from the first user in the electronic database that was stored for the first user during a previous transaction, sending a first message through the network connection to the second user device requesting that the second tangible or intangible item be provided to the first user, receiving a second message through the network connection confirming receipt of the second tangible or intangible item, and storing a second credit for the second user in the electronic database to complete the first transaction using a swapping module, and
- receiving a second request through the network connection from the second user device for the third tangible or intangible item that begins a second transaction, removing the second credit from the second user in the electronic database, sending a third message through the network connection to the third user device requesting that the third tangible or intangible item be provided to the second user, receiving a fourth message through the network connection confirming receipt of the third tangible or intangible item, and storing a third credit for the third user in the electronic database to complete the second transaction using the swapping module, wherein the first credit, the second credit, and the third credit are used to manage a swap of the second tangible or intangible item and the third tangible or intangible item among the first user, the second user, and the third user and wherein the first credit, the second credit, and the third credit each represents a right to request a future swappable tangible or intangible item for the equivalent value of at least one previously swapped tangible or intangible item.
