A method of downloading an electronic product to a pin-pad terminal involves the terminal transmitting to a network gateway a transaction proposal for an electronic product from a network device, and receiving from the gateway a transaction proposal response generated by the gateway in response to the transaction proposal. The transaction proposal response includes a transaction pointer associated with the electronic product. An electronic cash register receives an indication of a proposed payment amount for the electronic product. The pin-pad terminal receives from the electronic cash register confirmation of entry of the electronic product in an electronic shopping basket maintained by the electronic cash register. The terminal validates the confirmation of entry of the electronic product from a comparison with the transaction proposal response, and transmits the transaction pointer to the network device via the gateway. The terminal receives the electronic product from the network device via the gateway.
