Method for two-stage data transmission

A method is disclosed for sequential transmission of at least two sub-packages of the data package from an electronic communication transmitter to an electronic communication receiver. A first sub-package of the data package in a form comprehensible to the user of the electronic communication receiver is transmitted from the electronic communication transmitter to the electronic communication receiver. The first sub-package of the data package includes identifying information pertaining to a second sub-package of the data package, with the first sub-package of the data package having less data content than that of the second sub-package of the data package. The electronic communication receiver provides the user thereof with the choice of whether to have the second sub-package of the data package transmitted by the electronic communication transmitter. Transmission instructions are transmitted from the electronic communication receiver to the electronic communication transmitter in response to an affirmative selection by the user of the electronic communication receiver to the choice of whether to have the second sub-package of the data package transmitted. The second sub-package of the data package is transmitted from the electronic communication transmitter upon receipt by the electronic communication transmission instruction from the electronic communication receiver.
