In one embodiment, a transaction server facilitates a purchase transaction for goods or services between users at two mobile phones. The Purchaser initiates a request for a purchase transaction to a server, and is provided with a unique code ("purchasing nonce") that is uniquely associated with the request. The user of the first mobile phone provides the purchasing nonce to the Seller, who enters that value into the selling mobile phone. The selling mobile phone initiates a request to join the transaction as identified by the purchasing nonce. After confirmation of the Purchaser that the Seller can join the transaction, the Seller can itemize the goods for sale, which are electronically presented to the Purchaser for approval. After all items are selected, the Purchaser approves the transaction, and the transaction server can then transfers funds. An electronic receipt is provided to the Purchaser's mobile phone for confirmation. |
