<p>A method of completing a transaction with a payment terminal involves the payment terminal transmitting to a network gateway via a first communications network a transaction proposal identifying a proposed transaction with a network device, and receiving from the network gateway a transaction proposal response in response to the transaction proposal. The transaction proposal response specifies a pointer to the proposed transaction. The network gateway is configured to authenticate to the network device via a second communications network that comprises the network device. The payment terminal transmits over a payment network, distinct from the communications networks, payment particulars for the proposed transaction, and receives from the payment network a payment confirmation in response to the payment particulars. In accordance with the payment confirmation, the payment terminal initiates completion of the proposed transaction by generating a transaction completion request and transmitting the transaction completion request to the network device via the network gateway. The transaction completion request is generated from the transaction pointer, and requests completion of the proposed transaction with the network device.</p> |
