Abstract: A location-based marketing method includes steps of providing at least one first computing device including at least one memory operatively coupled to at least one processor, the at least one memory storing at least a listing of participating vendor geographical locations. At least one second computing device is in computing communication with the at least one first computing device. The method further includes steps of displaying to a user on a display screen of the second computing device a rotatable three-dimensional navigational interface including a plurality of faces, and by a geolocator module of the second computing device, providing to the at least one first computing device a geographical location of the user. The user geographical location is compared to the stored listing of participating vendor geographical locations. On determining a match, the first computing device initiates a user check-in procedure specific to the matching participating vendor.
