Abstract: These inventions relate generally to methods and systems for consummating asynchronous transactions between users. An “asynchronous transaction” is a transaction that involves an exchange of goods which does not require the seller, on the one hand, and the purchaser or renter, on the other hand, to schedule a time to meet to physically transfer the item to be delivered. The disclosed systems include an automated storage device in communication with a central server, the automated storage device comprising a plurality of locked storage compartments. A seller may deposit an item in a locked storage compartment for a purchaser or renter to pick up at a later time. The disclosure also includes methods to authenticate the seller and the purchaser or renter prior to granting access to the locked storage compartment, as well as methods to resolve disputes that may arise between the seller and the purchaser or renter.
