Abstract: A computerized method directed at smart phone users, that includes the step of utilizing a networked, computer device and software to provide “engagement services” via the video screens of the users' smart phones, can yield higher rates of customer conversions by configuring the computer device's software to provide: (a) a specialized interface that appears on the video screens of such smart phones, (b) prepared questions that appear on this interface and which are used in a dialog with a smart phone user to elicit the information necessary to establish the sales lead data of the smart phone user, (c) a real-time validation of the elicited information, and (d) prepared, follow-up responses, dependent upon the outcome of such validations, that also appear on the interface and which are provided so as to foster the continuation of the dialog and the collection of the necessary information.
