A system and associated methods for transmitting information using inaudible acoustic signals are disclosed. In at least one embodiment, a user application resides in memory on an at least one user device; the user application being configured for generating and processing the inaudible acoustic signals. Similarly, a vendor application resides in memory on an at least one vendor device; the vendor application being configured for generating and processing the inaudible acoustic signals as well. Upon a one of the user device and vendor device needing to transmit information to the other, the information is converted to an inaudible acoustic signal. With the user device and vendor device positioned proximal to one another, the inaudible acoustic signal is produced via a speaker of the one of the devices and received via a microphone of the other of the devices. The inaudible acoustic signal is then converted back to the information. |
