Abstract: A system may include wireless broadcast receivers and a wireless broadcast station configured to broadcast a wireless signal causing each of the wireless broadcast receivers to generate an audible advertisement and an inaudible promotion signal associated therewith. The inaudible promotion signal may be for promotion subscribers. The system may also include a digital promotions network (DPN) device, and a mobile wireless communications device carried by a given subscriber and that may include a microphone, a wireless transceiver, and a processor cooperating with the microphone and the wireless transceiver to wirelessly send notification of the inaudible promotion signal to the DPN device based upon receiving the inaudible promotion signal from a proximate one the wireless broadcast receivers. The DPN device may provide, after receiving the notification of the inaudible promotion signal, the given subscriber with the promotion associated with the inaudible promotion signal at a point-of-sale (POS) terminal.

Abstract: A system may include wireless broadcast receivers and a wireless broadcast station configured to broadcast a wireless signal causing each of the wireless broadcast receivers to generate an audible advertisement having a promotion associated therewith. The promotion may be for promotion subscribers. The system may also include a digital promotions network (DPN) device and a mobile wireless communications device carried by a given subscriber and that may include a microphone, wireless transceiver, and a processor cooperating with the microphone and the wireless transceiver to wirelessly send at least a portion of the audible advertisement to the DPN device based upon receiving the audible advertisement from a proximate one of the wireless broadcast receivers. The DPN device may be configured to provide, after receiving at least the portion of the audible advertisement, the given subscriber with the promotion associated with the audible advertisement at a point-of-sale (POS) terminal.

Abstract: The present disclosure relates to identifying consuming entity behavior across domains. Identity records are stored in a memory accessible to a computing system. Each of the identity records comprises at least one attribute, and the identity records originate from a plurality of domains. A determination is made as to whether a first one of the identity records identifies a consumption entity that is identified by a second one of the identity records. The first and the second identity records originate from separate ones of the domains, and the second one of the identity records is associated with a persistent key. The persistent key is associated with the consumption entity. The first identity record is associated with the persistent key if the first identity record is determined to identify the consumption entity.
