A system and method are disclosed to determine an action to be taken for currency delivery to a client. The method provides for the triggering and delivery of digital currency from television sets and audio devices to mobile devices by way of acoustic triggers, which are inaudible and/or indiscernible to the human ear. The acoustic triggers use a method of encoding an identifying data sequence into digital information, convert the digital information into analog audio pattern, transmit the pattern with loud speakers, receive the audio pattern with a microphone, convert the analog audio pattern into digital information, decode the digital information back to an identifying data sequence. The identifying sequence is then authenticate and validated with a server which associates the sequence with currency that can be redeemed at retail point-of-sale terminals or online and used to purchase goods and services. The different frequency sets that are present in these inaudible tones can be assigned monetary values that can be transferred between any two devices so long as the emitting device has a speaker and the receiving device has a microphone. |
